Planting method of potted orange 0 1 to obtain orange seeds. Orange seeds are obtained from fresh oranges bought in the market. Just stay when eating oranges.
Keep it clean. The collected orange seeds need to be kept clean to remove the pulp attached to the surface.
Change water. Soak the collected orange seeds in clean water and change the water once a day to make the seeds have enough water. It takes about a week to soak in water. Be sure to change the water every day to keep the seeds clean.
Peeling. After soaking the orange seeds for a week, take out the seeds and remove the thin skin on the surface of the orange seeds with tweezers. Don't hurt the inside of orange seeds when removing pulp, and carefully remove the epidermis, which is beneficial to the rapid germination and growth of seeds.
05 buried. After the epidermis is removed, prepare a pot of nutrient soil, and the soil taken from the vegetable field is the best. Bury orange seeds about two centimeters under the soil, then water them every day and wait patiently for the seeds to germinate.
Preservation method of potted citrus: breeding environment
As we all know, citrus is a southern fruit tree and likes warm and humid environment. The suitable growth temperature is 12.5 ~ 37℃, and the air humidity is relatively high. Potted soil with loose texture, good structure, organic matter content of 2% ~ 3% and good drainage is better. Sunshine can grow normally for 4 to 6 hours every day on average.
Potted soil:
Pots for potted citrus should not only satisfy the growth of fruit trees, but also be beautiful and firm. Because the crown is large and there are many fruits, we should choose large flowerpots, and all of them should have drainage holes, so as to discharge excess water in time and prevent water from rotting the roots. Citrus is not strict with the soil, but the soil should be properly mixed in potted plants. General pots: garden soil 1 serving, decomposed organic fertilizer 1 serving, river sand 0.5-0.8, plant ash 0.5-0.2. After the pot is ready, mix it evenly, finely crush it, then put it in a transparent plastic bag, sterilize it in the sun for a week, and turn it frequently.
Citrus planting:
After the soil of the flowerpot is done, it can be planted. First put 1 ~ 2 thick crumbs, gravel or sand at the bottom of the flowerpot for defecation, drainage and root ventilation. Before planting, apply decomposed organic base fertilizer in the basin. When transplanting, the root system of seedlings will not touch the base fertilizer, so as to avoid damaging the roots and crushing the seedlings. Add a small amount of pot soil, put the fruit seedlings in the center of the pot, let the roots extend around, and try not to bend the roots. When transplanting, water the plants first, leave a certain amount of fixed root soil when raising seedlings, cut the root system, but leave a certain amount of lateral roots, which is beneficial to absorption. Slowly add the pot soil, constantly lift the root, cover the soil to the root neck, and gently compact it by hand, so that the soil is closely connected with the root, and the surface of the pot soil is smooth and permeable. 2-3 days after planting, support the soil with poles to prevent the seedlings blown by the wind from hindering the growth of new roots and keep the soil moist.
How to water
Citrus likes humidity, so it is necessary to keep the basin soil moist and pay attention to whether there is water. If the topsoil in the basin is white, it needs watering. Tap the edge of the basin, the sound is crisp, indicating that the soil is dry and needs watering. Watering should be thorough, and it is advisable to have water seeping from the drainage hole at the bottom of the basin. The soil is too wet, which easily leads to rotten roots and needs drainage.
How to fertilize
Potted citrus is limited by pot soil, and the nutrient supply is very limited. Usually, more thin fertilizer should be applied. Apply decomposed liquid fertilizer once before the plants germinate, and then apply liquid fertilizer mainly containing nitrogen every 7 ~ 10 days to promote more branches and leaves and more spring shoots. Fertilize in time after each coring to promote the early maturity of branches. During the growth of citrus, you can sprinkle some cake fertilizer on the basin surface, so that some fertilizer can penetrate into the soil every time you water it, and enhance the fertility. After autumn, fertilization will be reduced, plant nutrition will be avoided, autumn shoots will be promoted, and fruits will compete for nutrients, leading to fruit drop.
Daily maintenance
Potted citrus, because of the small soil in the pot and limited nutrition, should be pruned. Through pruning, the reasonable distribution of nutrients in the tree can be adjusted, so that limited nutrition can be supplied to buds and leaves, and more fruiting branches can be formed, so as to achieve full branches of flowers and fruits. It takes about 2 years to change pots and soil, and at the same time, the roots should be trimmed to restore vitality.
Flowers are sparse and fruits are reduced, and citrus plants are potted, but the nutritional components are limited. If you want to concentrate nutrition on flowers and fruits, you must dilute flowers and reduce fruits. For example, some leafless branches, intraosseous branches and dense weak branches cannot bear fruit because of poor development, so flowers should be picked and deleted, and there are clusters of ethnic flowers, only a few well-developed strong flowers can bear fruit, so flowers should be thinned in time. Therefore, the decisive thinning of flowers and fruits is to achieve the purpose of protecting flowers and fruits. In addition, potted fruit trees pay more attention to ornamental value.
Precautions for eating oranges 1? Oranges and milk should not be eaten together? There is no scientific basis
There's a saying? Milk is not suitable for oranges? The reason is:? Citrus fruit or juice contains organic acids, which can denature and solidify protein in milk, but it is difficult to absorb after protein denaturation. ?
In fact, the liquid in human stomach is acidic, and the PH value of gastric acid (mainly hydrochloric acid) is between 1~3, which is a strong acid, thousands of times higher than the acidity of fruit juice. After milk enters the stomach, the protein contained in it is bound to be denatured and solidified by gastric acid, which is an inevitable process of protein's digestion and absorption. Therefore, adding sour substances (or eating them at the same time) to milk, such as citrus fruits or juice, is just beneficial to the digestion and absorption of milk (as are other foods).
Therefore, milk is rich in high-quality protein, calcium, vitamin A and vitamin B, while citrus fruits are rich in sugar, potassium, trace elements, vitamin C and dietary fiber. The combination of the two is excellent. Similarly, the combination of orange juice and milk is also very good;
2. Take medicine and avoid eating oranges.
Oranges are rich in fruit acid and vitamin C. When taking vitamin K, sulfonamides, spironolactone, aminopterin and potassium supplements, oranges should be avoided.
3, avoid fresh orange peel to make tea.
Most picked oranges are soaked with preservatives before they are put on the market. Preservatives are chemical agents, and soaked oranges have no effect on pulp, but the residual preservatives on orange peel are difficult to wash off with clear water. If such orange peel is soaked instead of drinking tea, it will be harmful to health.
Eating too many oranges will lead to stones.
Oranges are rich in water and nutrients, and contain a lot of more than ten kinds of nutrients such as vitamin C, citric acid and glucose. Proper consumption can nourish the body, especially for patients with chronic hepatitis and hypertension. Eating oranges can improve the detoxification ability of the liver, accelerate the transformation of cholesterol and prevent arteriosclerosis. Proper consumption can increase appetite, but improper consumption is useless. Children should not eat more oranges.
If oranges are rich in carotene, if eaten in large quantities, about 500 grams a day for two months in a row, high carotene may appear, which is manifested by yellow staining on the skin of hands and feet, gradually spreading to the whole body, accompanied by nausea, vomiting, loss of appetite, general fatigue and other symptoms, and sometimes easily confused with hepatitis.
Carotene is converted into vitamin A in the liver, but a large amount of carotene can not be converted in time in children's liver, so it is deposited in the whole body with blood and has adverse reactions to the body.
