Brassica napus boron deficiency, atrophy at seedlings is not long, flowering is not true, yield and quality will be affected. The application of boron fertilizer can increase the amount of pods in rapeseed, increase the seed setting rate and 1000-grain weight, and increase the yield by 10% to 20%. The rapeseed application of boron fertilizer can be based on, spraying or foliar fertilizer spraying. The base application was carried out during the transplanting of rapeseed, and 500 g of borax per acre was evenly mixed with organic fertilizer and then applied to a transplanting or transplanting ditch. Sprinkle application after transplanting, 500 grams of borax per acre with water dripping root.
The lack of boron in wheat and wheat will result in abnormal delivery at the seedling stage and “spontaneous panicle disease†in the later period, which will also lead to low wheat yield and poor quality. The addition of boron fertilizer can increase the seed setting rate of wheat and promote full grain filling. The application method is to spray borax solution with a concentration of 0.05% to 0.1% each at the delivery and jointing stages.
Potatoes (potatoes) are deficient in boron, and the plant growth point or the top of the potato is susceptible to death. It also increases the number of lateral sprouts and abnormal growth of the potato. Soaking the seed tube with a concentration of 0.1% borax solution for 4 to 6 hours after sowing can achieve a significant yield increase effect; it can also be sprayed during the growth period, generally spraying 2 to 3 times from the seedling stage to budding and flowering stage. 1% borax solution.
