Autumn wind blows, and the grains are fragrant. This is the harvest season. You see, corn is happy, showing people full fruits.

I like eating corn best, so my mother often goes to the market to buy me corn.

The shape of corn is not very beautiful, because its cylinder is wrapped in layers of coats. I carefully peeled off layer after layer. When I peeled off the "coat" of corn, I found that it was still covered with a layer of "blonde hair", just like a "blonde witch"! Tear off its blonde hair and it will show its true colors. This is the corn displayed in front of us. It's very different from what it just looked like. It is really bright and luxurious, like a delicate handicraft, like yellow pearls and jade grains inlaid with neat sizes, emitting charming brilliance.

I also know that corn is an annual plant and its flowers are unisexual. Its pollen needs external force to help it spread to the stigma of another flower to bear fruit. The growth process of corn is like this, but corn is rich in nutrition. It contains many vitamins, glucose, amino acids and minerals ... It belongs to coarse grains, and eating more corn is good for health.

The corn is ripe, delicious, sweet and fragrant, and the shiny corn grains make people drool. Really my "good friend".

This afternoon, the weather is very sunny. Grandpa moved all the corn that had been dried for several days into the house, and everyone joined the action of "peeling corn".

Grandpa has a small diamond in his right hand and dried corn in his left. He pierced the root of corn with the tip of this small drill, and scraped off two rows of corn one left, one right, one left and one right. In a short time, he turned the corn into a bare corn cob.

This is the most labor-saving method.

Grandma used a faster method: Grandma first waited for Grandpa to cut a path for the corn with a small drill, then put the corn with seams on the legs of the chair with shoes tied, and then began to rub on the soles. The corn kernels fell, but like disobedient children, they didn't want to get into the big round basket at all, so we picked them up all over the floor.

My sister and I were afraid that the chairs and drills were unsafe, so we decided to take them off by hand.

My sister learned grandma's method, found a corn cob as grandma's chair leg, and rubbed it up, but it didn't take many times. Who said she was too weak? I will use the most honest way: peel it by hand.

It's slow, but the corn won't fall out of the basket! Very practical.

Finally, everyone Qi Xin worked together to peel off the corn husks.

Full of a big round basket, Huang Cancan's is like gold.

Although my fingers are a little sore, I am still very happy to help my grandparents! Teacher's comment: The article is very real. Describe the scene of peeling corn kernels. Anyone who has done this kind of work knows what Grandpa's drill is like. You vividly expressed that I seemed to see my grandparents peeling corn kernels in front of my eyes.

The full text has reasonable conception, distinct levels, vivid and accurate language and complete and vivid expression.

Although my fingers are a little sore, I am still very happy to help my grandparents.

From here, we also see the image of a sensible good boy.

My earliest "reading" was just listening to books. In the process of listening to the book, I will think about what the next plot will be like. I also want to know whether the characters in this story are known before or heard in another story. Gradually, I feel that listening to books is like eating someone else's milk, so listening to books also tells me that the taste is eaten up.

Later, I began to read picture books, which were full of pictures without words. When reading them, I will think about what happened and why the people in the photos did it. These picture books fascinate me: Tortoise, Diary of Earthworms and so on.

In these picture books, I always feel that I can't learn good words and sentences. Finally, I gave up reading such books.

After a while, I heard that reading illustrated books can not only get good words and sentences, but also have opinions on pictures, so that you can never get tired of reading them.

I have seen big men in Grade One and small men in Grade Two, bears stuck in the bathtub and so on.

Later, I felt that I was so big that I should know the world and this country.

After a period of consideration, I began to relax my confidence and read books on popular science and literature. In these books, I learned higher knowledge, good words and phrases, and my understanding of the country and the world. When reading Little Copernicus, Summer Adventure, and If you give me three days of light, I summed up an experience: deep reading is the end of the book.

Gorky said that books are the ladder of human progress. For everyone, we are inseparable from books. Books are the source of human progress.

7. I have made progress. I made progress this time, because I got high marks in this exam, and I also managed to look at the questions and think independently, but I still regret four questions.

These four questions are: please carefully judge the second small problem in the second big problem. Weight of each ham sausage 10g. I didn't think about it carefully, so I looked it up. If I can think about this question carefully, what is 10g? I wouldn't have lost two points. I have my first regret.

Please fill in the first big question and be sure to read it carefully. At that time, the eighth question, I thought the same thing when I filled in the blanks. In order for 0 to appear in the middle of the quotient of 8□2÷8, I have to fill in a number that can be divisible by 8. When the teacher handed out the test paper, I saw this question again and suddenly realized that it was enough to be less than 8. I made a mistake in this question because I didn't consider it when I did it.

This paper introduces the basic knowledge and contract of corn. Recently, a study by the German Nutrition and Health Care Association shows that corn has the highest nutritional value and health care function among all staple foods.

Prevent heart disease and cancer. In this study, which lasted 1 year, experts compared the nutritional value and health care function of many staple foods such as corn, rice and wheat.

The results show that the vitamin content in corn is very high, which is 5- 10 times that of rice and wheat.

At the same time, corn contains a lot of nutrients and health-care substances, which also surprised experts.

Besides carbohydrates, protein, fat and carotene, corn also contains nutrients such as riboflavin and vitamins.

These substances are of great benefit in preventing diseases such as heart disease and cancer.

The research also shows that the nutritional value of special corn is higher than that of ordinary corn.

For example, the content of protein, vegetable oil and vitamins in sweet corn is 1-2 times higher than that in ordinary corn; The selenium content of "life element" is 8- 10 times higher; Among 17 amino acids, 13 amino acids are higher than common corn.

In addition, the moisture, active substances, vitamins and other nutrients of fresh corn are much higher than those of old corn, because the cultivation branch of corn drops rapidly during storage.

Professor Rahman, a famous German nutritionist in charge of this research, pointed out that among the more than 50 kinds of nutritional and health-care substances that have been proved to be the most effective today, corn contains 7 kinds-calcium, glutathione, vitamins, magnesium, selenium, vitamin E and fatty acids.

It has been determined that every100g of corn can provide nearly 300 mg of calcium, which is almost the same as that contained in dairy products.

Rich calcium can lower blood pressure.

If you take 1 g calcium every day, your blood pressure will drop by 9% after 6 weeks.

In addition, the carotene contained in corn can be converted into vitamin A after being absorbed by the human body, which has the function of preventing cancer; Plant cellulose can accelerate the discharge of carcinogens and other poisons; Natural vitamin E has the functions of promoting cell division, delaying aging, lowering serum cholesterol, preventing skin lesions, relieving arteriosclerosis and brain function decline.

The researchers pointed out that lutein and zeaxanthin contained in corn can fight against eye aging.

In addition, eating more corn can also inhibit the side effects of anticancer drugs on human body, brain cells, and enhance people's basic knowledge of brain power and memory. 1. Common sense of corn Gramineae corn belongs to the genus Zea Mays L. (also known as corn), with tall plant type, wide and long leaves and ectopic male and female flowers. The male inflorescence grows at the top of the plant, and the female inflorescence (spike) is inserted between the axils of the middle and upper leaves, which is a heteroflower.

There are common names such as corn, bonzi, Hosta, and corn pearl rice, which are native to South America.

7000 years ago, American Indians began to grow corn.

After Columbus discovered the New World, he took corn to Spain. With the development of world navigation, corn has gradually spread all over the world and become one of the most important food crops.

About the middle of16th century, China began to introduce corn, which was introduced to India in18th century.

So far, corn has been planted on all continents in the world, and it has become the most important feed crop.

In the world, although there are feed crops such as barley, oats and sorghum, its output is really the tip of the iceberg compared with corn.

Corn accounts for more than 65% of the world's coarse grain output and 90% of China's coarse grain output.

Corn is the most important raw material for making compound feed, generally accounting for 80%, and the remaining 20% is high-protein additives such as soybean meal or fish meal.

Among the cereal crops in the world, the planting area and total output of corn are second only to wheat and rice, ranking third and the average yield is the first.

It can be planted from 58 north latitude to 42 south latitude, from Turpan Basin in Xinjiang, China, which is below sea level, to high altitude areas above 3600 meters above sea level.

North America is the largest, followed by Asia, Latin America and Europe.

China has the second largest corn planting area and total output in the world.

It is concentrated in the oblique belt passing through North China from northeast to southwest, and the planting area accounts for about 85% of the national corn area.

Corn seeds contain 70-75% starch, 10% protein, 4-5% fat and 2% multivitamins.

The contents of protein, fat, vitamin A, vitamin B 1 and vitamin B2 in cereals are higher than those in rice.

There are more than 500 kinds of processed products made from corn.

The seeds of maize include pericarp, seed coat, embryo and endosperm, but the pericarp and seed coat are closely connected and difficult to separate.

The endosperm consists of aleurone layer and starch layer.

Seeds are yellow, white, purple, striped and other colors due to different varieties. The outermost peel is usually transparent and colorless, and only a few varieties are purplish red or striped.

Embryo is located at the basal surface of the grain, accounting for 10- 15% of the total weight of the grain, endosperm accounts for 80-85%, and pericarp and seed coat account for 6-8%.

The grain shape, size and transparency vary with the variety type, for example, the horse tooth variety is large, flat and nearly rectangular; Hard grain varieties are small, nearly round and have good transparency.

Corn is a warm short-day crop.

It takes 90- 150 days from seed germination to new seed maturity.

Late-maturing varieties generally have a long growth period because of early sowing date and low temperature in the early growth stage; On the contrary, it is short.

The growth period of early-maturing varieties in China is 90- 100 days, and they are often sown in spring.

Day-length and spectral components are closely related to the growth and development of maize.

The whole growth period can be divided into three stages: seedling stage (from sowing to jointing), ear stage (from jointing to heading) and flower and grain stage (from heading to maturity).

From germination, it goes through the processes of emergence, rooting and stem and leaf formation.

Spring corn in northern China needs 12- 15 days for sowing from mid-late April to early May, and the jointing period is around mid-June.

Summer-sown corn is sown from late May to mid-late June, and usually emerges after 5-6 days, with jointing stage in early and middle July.

The growth characteristics are mainly root growth, and the growth of root system is greater than that of aboveground stems and leaves.

The dry matter weight of roots is 1- 1.5 times that of stems and leaves.

Compared with leaves at seedling stage, leaves grow faster than stems.

The heading date of spring sowing corn is in the middle and late July, and summer sowing corn is in the middle and late August, which varies with varieties, regions, sowing dates and cultivation conditions.

The reproductive characteristics of this period are not only the vigorous growth of roots, stems and leaves, but also the rapid differentiation of female and male ears, which is a period when vegetative organs and reproductive organs flourish at the same time.

Second, the utilization of corn Because of the many characteristics of corn seeds and plants in composition, the extensive utilization value of corn is determined.

In the world's total corn output, direct ...

It is not easy to pick corn with 700 words. You have to break the corn stalks first, and then pick corn on them.

It's really not easy to pick it all the way. There are many bugs in the field, which scared my city children to death.

Most importantly, there are a group of aphids lying on some corn! Oh, mom, I'm scared! Corn leaves are the most stinging. It hurts and itches when I am pricked by a corn leaf. It's really hard.

Half an hour later, I picked less than twenty corn cobs, which was really inefficient.

Alas! I really didn't want to pick it at that time, but seeing the farmers' uncles working so hard, my fighting spirit was stimulated again, and my blood began to boil again! With the crisp sound of "cut, cut", I also began to pick up the corn hard! It is naturally handy to do it. As long as the roots of the corn fruit are gently broken off, the corn will come down, which is still very easy! Thanks to me, the corn was quickly picked (hee hee, don't say I boast). Finally, we have to meet the next difficult battle.

Hard work: shipment whew! Here, the tractor my uncle bought can be of great use. With this novelty, transportation is not a problem, but we still have to load corn.

Loading corn is simple, but it takes a lot of effort. Throw the picked corn pile on the tractor. How many cars can pull out so much corn?

* * * will soon be bored, what should I do? Keep pretending, if you are tired, you have to pretend, otherwise there will be no sweet corn.

We kept throwing corn at tractors and loading them one by one.

We were all sweating, and then I realized the hardships of being a farmer. Without the hard work of the farmer's uncle, where did these attractive foods come from, and where did we have this wonderful time? Fortunately, my brothers and sisters who went to school in other places also came to help. We all worked together in Qi Xin and finally got through this.

Hard work: bring back the corn, it's time to peel the corn.

It's simple. Just pick a nail at the top of the corn husk, and the husk will loosen automatically, and then gently tear it off.

Just a pile of corn. It will take several days to peel it off.

Don't say anything, peel! We peeled and peeled day and night for four days, and finally consumed this "mountain", ha! This "harvest war" is coming to an end!

290 words of corn as the saying goes, before and after Qingming, plant melons and beans.

No, I went to my grandmother's house in the country on weekends, and my grandmother went to plant corn in the back of the house.

The first step is weeding in the open space.

Grandma gave me a hoe to get up.

As soon as I started, I picked up my hoe and turned it around on the battlefield.

After working for a while, I was tired and anxious. Except for a small piece, Grandma had no grass anywhere except half of it.

So I asked my grandmother for advice.

I pulled out a bunch of grass roots, but I can't pull them anymore. I turned up the grass roots and rolled them as I dug, just like rolling a carpet. One roll is a big roll. What a great idea! I also rolled up like my grandmother. After a cup of tea, we wiped out a large area of "grassland".

Next, it's time to dig a hole and sow.

Grandma first dug a row of pits neatly with a hoe, and I dug with a sickle, sowing seeds while digging. I didn't know how many pills to put at first, so I put 6-8 pills casually and quickly shouted, "Wrong, wrong, put two."

"Well, can't, so we have to dig again. I don't know how to grow corn.

At sunset, we finally finished all the tasks. We are like gray monkeys. You look at me, I look at you.

But it also honed my will, and I feel quite happy.

The four OO words in the composition "Harvest Corn" in the first volume of the fourth grade are written according to the model essay or according to one's own practical experience.

Writing method: 1). Determine the center and write the profound meaning.

Summer vacation is the season when corn is ripe.

One sunny day, after breakfast, grandma took her brother and sister with me to break corn in the corn field.

I followed my grandmother's example, carried a basket on my back and walked happily to the cornfield.

When I got to the cornfield, I immediately picked up the corn.

I first separated the leaves wrapped in corn layer by layer, and then forcibly broke the leaves and roots, and the corn took off its clothes outside, revealing its true colors.

I put these corn in the basket.

Time and time again, we didn't finish picking the corn in this field all morning.

Next, we need to transport the corn home safely.

Every time, I put 20 corn in the basket, and then slowly carry the basket with corn home.

When I got home, I took the corn out of the basket, put it away, and went to the cornfield to carry it home.

My sister is the funniest when I recite corn.

She is only five years old this year and knows she is the youngest and weakest. In order to compete with us, she chose a big basket full of corn.

When she was carrying it, because the basket was too heavy, she couldn't carry it at all, so she began to cry loudly.

No choice, my brother and I had to help my sister share some corn in her basket and carry it home.

What is even more bizarre is that this time my sister actually only carried a corn home.

I looked at my sister's lovely appearance and thought: I might as well walk home with a corn in my hand and no basket on my back! After two days of contact, we broke all the corn in the corn field and successfully shipped it home.

Next, beat the corn-that is, take all the corn kernels off the cob with a machine.

Several of us are responsible for the division of labor and cooperate with each other.

One person is responsible for putting the corn in the basket and giving it to another person. Another man put the corn in the basket into the corn thresher one by one. After the corn cob enters the machine, piles of corn kernels come out directly from the other end of the machine.

One person is responsible for pushing the corn kernels out of the machine to dry, so as to prevent the corn kernels from piling up too high and ramming into the machine again.

I am busy putting the corn in the basket, and I am busy pushing it away, and I often sweat.

While we were busy corn-harvesting, the weather was bad and it began to rain, but we had to temporarily stop corn-harvesting, quickly pile up corn kernels and cover them with plastic sheets to prevent them from getting wet by the sun rain.

When the rain cleared up, we hurried on with the corn, and it took more than an hour to finish all the corn.

In the process of harvesting corn this time, I am often sweating and panting, but looking at piles of corn kernels, I can't say how happy and excited I am.

This time in grandma's hometown, I personally participated in harvesting corn, which not only made me realize the hardship and difficulty of farmers' uncles' work, but also exercised my will to work hard.

From then on, I must learn to cherish food and cherish the happy life I have.

I like corn in my hometown. My hometown is a place rich in sugarcane, rice and peanuts.

But I still like the corn in my hometown best.

When the flowers bloom, spring comes, and the farmer's uncle scatters corn seeds into the already loosened fields.

After the seeds have eaten enough nutrition in the ground, they stick their heads out in droves and stretch out a small leaf roll.

After about two or three weeks, the corn has sprouted and grown leaves, and the leaves of the corn are swaying in the wind, just like a slim girl dancing in the field.

After more than a month, the leaves of corn are more lush, and the thick corn stalks are particularly energetic under the moisture of rain and dew.

In a blink of an eye, summer came and the whole field became a green ocean.

The breeze blows, and corn leaves come and go, like waves in the sea.

The waves are green, green and bright.

The corn on the cob has long and thin hairs on its head, just like grandpa's brown beard.

Teacher Qiu brought the joy of harvest. The corn in the field is ripe, and the golden corn is hanging on the corn stalk. The granules are full, and they are greedy at first sight.

The farmer's uncle happily came to his field to collect corn.

After harvesting corn, children always urge adults to cook corn. Corn is very fragrant, slightly sweet and has an endless aftertaste.

I like corn in my hometown.

...

My hometown is beautiful Tai 'an.

I love my hometown, and I love the cornfields in my hometown even more.

After Tomb-Sweeping Day, the drizzle fell gently, for fear of disturbing the sleeping corn seed doll underground.

It rained and cleared for three consecutive days in Mao Mao.

The corn seed doll grew up desperately regardless of her mother's stop! The corn seed doll finally poked out its little green head.

They looked around as if they had come to another world, and all the sunshine and rain belonged to them.

Seeing this, the corn seed doll is determined to break through all obstacles and grow up quickly in a good time.

After more than twenty days, the corn seed doll grew up and became a corn sister.

Look, Sister Corn is wearing green clothes, a white skirt and white shoes.

A breeze blew, and Sister Corn danced as if to show off her youth to people again.

When the corn is ripe, grandma and I will go to break the corn together.

"Oh, this corn is great!" I rushed over and broke it.

Grandma and I tore down the whole car.

When I got home, I picked a few tender ones and cooked them in a pot.

Soon, a refreshing aroma came to my face.

I picked up a big one and put it in my mouth. Wow! It smells good! Corn stalks can quench your thirst! Every afternoon, my friends and I will go to the corn field to chew corn stalks. Its water is really delicious! Corn fields in my hometown! You don't want anything from others, but you give everything to them.

Corn fields in my hometown! I want to praise you!
