Avoid applying fertilizer to the acupoints. Fertilizer application is easy to cause local fertilizer concentration to be too large, resulting in the roots not being absorbed evenly, and even causing rape poisoning, burning roots, and affecting growth, especially in the application of ammonium bicarbonate. Therefore, it is best to fertilize rapeseed by ditching between rows. The general ditch is 10 cm deep and 20 cm wide.
Some farmers who refused to apply the seedlings and fertilizers were only applied to the farmer's fertilizer for seedlings two months after the transplanting of the rapeseed. In fact, at this time, rapeseed is need to absorb more nutrients, such as nutrition can not keep up, it will affect the growth of rapeseed, and even cause deadlock. To this end, in the transplanting of rapeseed, it is necessary to use the dilute excrement as a fixed root water; after living the tree, use 250-500 kilograms of human excrement per acre, and 2 to 3 kilograms of urea, and add water to fertilize it to benefit the strong seedlings.
Avoiding the application of boron fertilizer Rape is sensitive to the reaction of boron fertilizer. Boron deficiency can cause physiological diseases, leading to poor root development, only flowering is not strong or the seeds are not full. Generally, 0.2-0.3 kg of borax is used as the base fertilizer per acre. At the same time, in the rapeseed seedling stage, the bud stage, and the flowering stage, the boron fertilizer is sprayed once, and each time 50 grams of borax is added with 50 kg of water and sprayed.
