Boron is one of the trace elements that are indispensable for the growth and development of crops. Winter crops such as rapeseed, broad beans, wheat, potatoes, green manure and winter vegetables are all crops that respond well to boron fertilizer. The lack of boron will affect growth, both in terms of yield and quality. Practice has proved that the addition of boron fertilizer on winter crops can achieve significant yield-increasing effects, and it is a production-increasing measure with less investment and great effect.
1, rape. The lack of boron in rapeseed, the atrophy of seedlings is not long, and the flowering period is not real, which has a great influence on the yield and quality. Adding boron fertilizer can promote the normal growth of rapeseed, increase the pod, increase the seed setting rate and 1000-grain weight, and increase the yield by 10%-20%. Brass can be applied to the rapeseed, applied and applied as foliar fertilizer. When the rapeseed is transplanted, 500 grams of borax per acre is mixed with the organic fertilizer and then applied to the transplanting point or transplanting ditch; after the transplanting, 500 grams of borax per acre is added with water to drip the root; Shiyi sprayed a borax solution with a concentration of 0.2% in the seedling stage, the bud stage and the initial flowering stage, and the sprayed liquid per acre was 30 kg, 50 kg and 75 kg respectively.
2, broad beans. Boron deficiency in broad beans can also produce flowers without realizing images and affecting high yields. Adding boron fertilizer can reduce flower pod shedding, increase pod and grain weight, and increase yield by 15%-20%. It is advisable to spray a concentration of 0.1% borax solution in the seedling stage, the initial flowering stage and the full flowering stage respectively. The seedling period of each acre of spraying fertilizer is 30 kg to 40 kg, and the flowering period is 50 kg to 75 kg.
3. Wheat. The boron deficiency in wheat is not normal in the seedling stage. In the later stage, there is a "spear and inconsistency", which is more open, low in yield and poor in quality. Increasing the application of boron fertilizer can increase the seed setting rate and promote the fullness of the grain, increasing yield by about 10%. It is advisable to spray a borax solution with a concentration of 0.05% to 0.1% in the tillering and jointing stages, and each time the spraying liquid per acre is about 50 kg.
4, potatoes. Potato (potato) is deficient in boron, the plant grows or the top is easy to die, the lateral buds increase and grow rapidly, and the internodes are short, which makes the plants short clusters, which leads to small tubers and low yield. Soaking the seed potato block with a concentration of 0.1% borax solution for 4 hours to 6 hours, can achieve significant yield increase. It can also be sprayed during the growth period, generally spraying 2 times to 3 times with 0.1% borax solution from the seedling stage to the flowering stage of the bud.
5, green manure. The green manure lacks boron, the nodule is poorly developed, and the nitrogen fixation ability is poor, making it difficult to obtain high yield. Spraying a concentration of 0.2% borax solution in the seedling, bud and early flowering stages can increase the yield of fresh grass by more than 20%, and increase the seed yield by more than 25%.
In addition, winter vegetables such as cabbage, celery, lettuce, beets, radishes, etc. are all vegetable crops that are sensitive to boron, and the addition of boron fertilizer can achieve good yield and quality improvement. The application of boron fertilizer in vegetables is mainly applied as foliar fertilizer. It should be sprayed 2 times to 3 times in the middle stage of fertility, and each time the spray is 30 kg of borax solution with a concentration of 0.1% to 0.2%. 50 kg.
