In winter, adding boron fertilizer to crops can achieve significant yield increase. Brassica napus boron deficiency, atrophy at seedlings is not long, flowering is not true, yield and quality will be affected. The addition of boron fertilizer can increase the amount of pods in rape, increase the seed setting rate and 1000-grain weight, and increase the yield by 10%-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. Spraying should be performed with a 0.2% borax solution at the seedling, bud and early flowering stages. The deficiency of boron in broad bean beans can also produce flowers without effect, affecting high yields. The application of boron fertilizer can reduce the loss of calyx, increase pod and grain weight, and increase production by 5%-20%. The application method was to spray 0.1% borax solution once at the seedling stage, early flowering stage and flowering stage. The amount of spray per acre is: 30 kg to 40 kg for seedlings and 50 kg to 75 kg for flowering. 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 application 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%-0.1% once during 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. Seed soaking in the borax solution with a concentration of 0.1% for 4 to 6 hours can achieve a significant yield increase effect; it can also be sprayed during the growth period, generally spraying 2-3 times from the seedling stage to budding and flowering stage. 1% borax solution.
