Introduction to Chinese names: Organic Strawberry Kingdom: Plant Kingdom: Angiosperm Kingdom: Dicotyledonous Plants Order: Rosaceae: Rosaceae: Division of Strawberry, Composition Comparison, Related News, Division Compared with Common Strawberry 1. It is forbidden to use synthetic substances such as pesticides, fertilizers and hormones in the production and processing of organic strawberries, and genetic engineering technology is not allowed; Other agricultural strawberries allow limited use of these substances, and genetic engineering technology is not prohibited. 2. Organic strawberries have strict regulations on land production and transformation. Considering that some substances will remain in the environment for a long time, it will take 2 ~ 3 years for the land to produce other strawberries to produce organic strawberries, but there is no requirement for the land change period to produce green and pollution-free strawberries. 3. The quantity of organic strawberries must be strictly controlled, requiring a fixed plot and a fixed output. Other strawberries are not so strict. Organic strawberries are naturally more expensive than non-organic strawberries because of strict planting techniques. Definition of virus-free strawberry Virus-free strawberry is a kind of organic strawberry, which is an organic strawberry fruit picked after breeding, planting and growth through virus-free technology of individual details of organic strawberry. Virus-free process 1. Take meristem cells of strawberry; 2. dedifferentiation into universal callus; 3. Carry out cell culture in vitro; 4. Wait for it to grow into a plant; 5. Raise seedlings. Why do organic strawberries have no viruses? Just like the human body, strawberries contain a lot of viruses, especially natural organic strawberries. In the stage of cell division, the virus easily invades the fruiting body. Strawberries infected with virus will lead to individual deformity, poor taste and decreased yield. Virus-free technology has the super ability of "turning decay into magic", just like immunizing strawberries, which makes them have the ability to resist viruses during their growth. This kind of strawberry can grow bigger and will not rot, because they will not produce toxins to affect their growth. Compared with non-virus-free strawberries, virus-free strawberries have good appearance, uniform and neat appearance, bright color, no deformity, large fruit, and the maximum single fruit weight is 60-80 grams. For example, the quality of eggs is good, and the disease resistance, high temperature resistance and cold resistance of plants are enhanced. There are basically no pests and diseases, and generally no spraying is needed, so that real green organic strawberry fruits can be produced. Misunderstanding of the concept of organic products 1. Organic products refer to products that do not use chemical synthetic substances. 3. The yield of crops planted by organic method is definitely lower than that planted by modern cost. Organic strawberry cultivation in greenhouse. Organic crops and their products are of low quality and poor nutrition. 5. Organic products must be pollution-free and contain no chemical residues. 6. The production of organic products is simply to use organic fertilizer instead of chemical fertilizer. 7. Organic products have a lot of labor input and high cost. Organic product certification mark All organic products listed, including organic strawberries, must be certified by relevant departments before they can be sold. Organic products sold without a license are fake and shoddy products. The chart of organic product certification marks in China and some countries is as follows: 1. China organic product certification mark II. European organic product certification mark 3. American organic product certification mark 4. Japanese organic product certification mark components are more common. Strawberry is an edible fruit and vegetable, also known as raspberry, raspberry, raspberry and so on. , is the floorboard of Rosaceae strawberry plants, there are more than 50 species in the world. Strawberries originated in South America and are widely planted in Europe and other places. This species is a horticultural hybrid, and its parents are American F. virgirniana Duch. And Fusarium Chile. The hybrid is an octoploid (2n=56) plant. At the beginning of the 20th century, many varieties of strawberries were introduced to China and widely cultivated, with more than 2,000 varieties. The fruit is bright red and beautiful, soft and juicy, sweet and sour, and fragrant. Strawberry is rich in nutrition and contains many effective ingredients. According to the determination, every100g of strawberry pulp contains 8-9g of sugar, 0.4-0.6g of protein and 0.00mg of vitamin C 50-100g, which is 7-10g higher than that of apples and grapes. Strawberry is rich in organic acids (such as amino acids, fructose, sucrose, glucose, citric acid, malic acid, nicotinic acid), pectin and other nutrients, and its essential minerals and some trace elements such as malic acid, citric acid, vitamin B 1, vitamin B 12, carotene, calcium, phosphorus, iron, potassium, zinc and chromium are also higher than those of apple. Strawberry is an important source of cellulose, iron, potassium, vitamin C, flavonoids and other essential components for human body. These nutrients have a good role in promoting growth and development, and are easily digested and absorbed by the human body. Eating more will not cause a cold or get angry. They are healthy foods suitable for all ages, which are of great benefit to the elderly and children. Eating strawberries after meals can break down food fat and promote digestion. Strawberry is cool, sweet and sour, moistening dryness, promoting salivation, benefiting phlegm, strengthening spleen, relieving alcoholism, enriching blood and lowering blood fat, which has a good curative effect on leukemia and anemia, and also has a certain preventive and therapeutic effect on gastrointestinal diseases and cardiovascular diseases. Known as the "fruit queen". No wonder Taiwan Province province calls strawberries "living vitamin pills" and Germans call them "magic fruits". Nutritional analysis of strawberry 1. Carotene contained in strawberry is an important substance to synthesize vitamin A, which has the function of improving eyesight and nourishing liver. 2. Strawberry has a certain nourishing and conditioning effect on gastrointestinal tract and anemia; 3. Strawberry can not only prevent scurvy, but also prevent arteriosclerosis and coronary heart disease. 4. Strawberry is a plant rich in tannic acid, which can absorb and prevent the absorption of carcinogenic chemicals in the body and has the function of preventing cancer; 5. Strawberry contains aspartic acid, which can naturally and peacefully remove heavy metal ions from the body. Strawberry has bright color, soft and juicy fruit, rich fragrance, sweet and sour taste and rich nutrition, which is deeply loved by consumers at home and abroad. It belongs to high-grade fruit. The latest research on the nutritional components of organic strawberries is more nutritious than ordinary strawberries 1. Research at Washington State University: Professor John Riside from the Department of Soil Science at Washington State University wrote a paper and published a study on strawberries in PLoSONE, an online magazine published by the Public Library of Science. Strawberries grown with organic fertilizer are more nutritious and delicious than those grown with traditional methods. The nutrients of organic strawberries include antioxidants and vitamin C, which are not only richer than ordinary strawberries, but also have a longer shelf life. The research was supported by the Federal Organic Food Promotion Center and organic food companies. Rashid's team includes Preston Andrews, an associate professor of horticulture at Washington State University, and seven other experts. It took them two years. In California, the taste and nutrition of strawberry were compared in 13 organic commercial field, and the chemical and biological characteristics and properties of 3 1 soil were analyzed, which was the most comprehensive research of its kind. Rashid and his research team found that berries produced in organic fields are equal to or greater than those produced in traditional fields in almost every major index, and the contents of antioxidants and vitamin C in strawberries cultivated in organic nutrition in soil are higher. However, scientists also pointed out that high planting cost and low yield are the biggest challenges facing organic strawberries. The chemical-free DNA analysis of organic soil in the research of Washington State University found that organic strawberry "* * * has greater huge and unique polygenic genetic diversity". This is a key measure for researchers to explain soil adaptability and emphasize the ability to grow crops. The research achievements of Washington State University include the following three aspects: (1) Organic soil chemistry and biology, including photosynthesis, nitrogen, enzyme activity and key properties of trace elements. (2) Compared with the berries planted by traditional methods, organic strawberries are delicious in open packaging for half a day. (3) Organic strawberries have more dry matter or are thicker. 2. After analyzing the research data of the past 50 years, the British Food Standards Agency found that the nutrition of organic crops is not higher than that of traditional vegetables. However, Reginald said: "In the past 65,438+00 years, scientists have repeatedly studied the nutrition of organic plants, of which 8 out of 65,438+00 studies believe that organic food is indeed nutritious." According to the researchers of Washington State University, after collecting and analyzing 26 organic strawberry farms and common strawberries in Watsonville, California, including the same soil, strawberry varieties and planting time, the period was as long as 2 years, and it was found that organic strawberries contained more antioxidants and vitamin C, and the storage period was longer. The DNA analysis of organic soil also found that the soil contains more kinds of microorganisms, so it is very beneficial for planting. Researcher Reginald said: "After analyzing various indicators, it is found that organic strawberries are almost better than ordinary traditional strawberries." However, he also found that the appearance of organic strawberry is smaller than that of ordinary strawberry 13.4%, and its potassium, phosphorus and other components are obviously lower than that of ordinary strawberry. In addition, scientists also believe that the high cost and low yield of organic strawberries are indeed the biggest challenges faced by organic crops.
