Corn and soybean mixed cultivation techniques

Corn and soybeans are mixed in the same hole to make full use of light to achieve the purpose of increasing production and income. Firstly, before and during the growth period, the leaf area per plant is small, and all of them can use the direct light of the sun. By the late soybean, scattered light from the lower layer of the corn leaf can be used, so the light is more abundant; secondly, the fertilizer and water are sufficient, and nutrient complementation can be achieved. Bacteria can immobilize the free nitrogen in the soil, and can also be used by maize in the same cave, in addition to its own needs, while the maize root can secrete acidic substances to decompose the insoluble mineral elements in the soil into quick-acting nutrients for soybean absorption and utilization. Can get monocropping soybean and can not get the seed fertilizer and top dressing; then is to reduce the degree of pests and diseases, soybean covered by corn to avoid the maggots, bean hornworm, borer and other hazards, so as to achieve the effect of increasing production, the main cultivation techniques are as follows:
First, choose the appropriate variety. Maize should be selected for high productivity of single plant varieties, soybeans should be selected earlier than corn, shade-tolerant performance is good, more branched varieties.
Second, rational dense planting, mixed with the points. 2800 corns per mu and 5600 soybeans are the best.
Third, the preparation of soil, nutrition seedlings nursery. One corn seed per hole, two kinds of soybeans, one-off Miao Qi, Miao Zhuang.
Fourth, timely transplanting. Normal corn is transplanted when two leaves are in one heart and three leaves are in one heart.
Fifth, scientific fertilization management. Apply base fertilizer, heavy ear fertilizer, mainly farmyard fertilizer, supplemented by commodity fertilizer.
Sixth, cultivating soil and preventing pests and diseases.
Seven, timely harvest. It is more difficult to harvest the soybeans with the same point and mix, and all the stems and pods turn yellow, and the grains in the pods are detached. When the sound is shaken, the soybeans are immediately harvested. Generally, 450-500 kg of corn are harvested per mu, and 70-100 kg of soybeans are collected.
Corn and soybeans are mixed in the same hole and are suitable for growing farmers with more land and less land.

Fat contains more linoleic acid and less oleic acid. The effective ingredients of mushrooms can enhance the function of T lymphocytes, thereby improving the body's ability to resist various diseases. Mushrooms contain crude fiber, semi-rough fiber and lignin that are difficult for the human body to digest. It can maintain the water balance in the intestine, absorb excess cholesterol and sugar and expel it from the body. It can prevent constipation, bowel cancer, arteriosclerosis, diabetes, etc Both are very beneficial and have a significant effect on lowering blood pressure.
