The cultivation of rapeseed Daejeon requires mastery of the principle of “industrious planting of Miaofei, increasing application of wax fertilizer, skillful application of spring manure, stable application of manure fertilizer, and seedling planting of fertilizers†to make sure that the spring season is strong.
(1) Miaofei is used as a ground. After 20 days of rape planting, topdressing was carried out in two batches, each time, 5 to 7.5 kilograms of urea per acre was poured and poured.
(2) Add wax fertilizer. In January, 1,000 kg of organic fertilizer was applied in Mushi, combined with cultivator and weed control to prevent freezing and keep warm.
(3) Qiao Shichun fertilizer. In early February, urea was applied at 5-7.5 kg per acre.
(4) Apply fertilizer steadily. When è–¹ high 6-8 centimeters, apply urea 7.5-10 kilograms per acre and apply appropriate phosphorus and potassium fertilizers.
(5) See seedlings apply fertilizer. In the beginning of the rape in late March, urea supplemented with 3-5 kg ​​was applied to the poor rapeseed field.
(6) Increase boron fertilizer to prevent "flowering but not realizing". "Double-low" high-quality rapeseed is more sensitive to shed elements, and the lack of sheds will cause "flowers but not realities", which will seriously affect production. For the application of boron fertilizer, 30-35 g (1/3 package) of high-efficiency instant boron fertilizer is applied per acre at Daejeon seedling stage and 10 kg of water is sprayed evenly, and then 65-70 g/mu (2/3 pack) per acre in flood season. ) Efficient instant boron fertilizer plus 20 kg of water evenly sprayed.
Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
