The first is the application of fertilizer. That is, the boron fertilizer is applied to the soil before the live rape or the transplanted rape, and the whole growth and development of the crop is required. In the boron-deficient soil, 15 kg of fine dry soil is mixed with 0.5 kg of borax per 667 square meters or mixed with farmyard manure and chemical fertilizer, but the boron fertilizer cannot be directly contacted with seeds or roots.
The second is topdressing. In the late rapeseed stage, before and after flower bud differentiation, during the twitching period (15 to 30 cm high), 0.2% borax aqueous solution or 0.1% boric acid aqueous solution was sprayed in the flowering stage, and 50 liters of fertilizer solution was used per 667 square meters in the later stage. If it rains after spraying, it needs to be re-sprayed.
The third is to cooperate with the application. Boron fertilizer combined with farmyard manure and chemical fertilizer can better exert its potential for increasing production. 0.5 kg of borax per 667 square meters is better with other fertilizers.
