Boron is one of the indispensable trace elements in the growth and development of crops. Winter crops such as rapeseed, faba bean, wheat, potato, green manure and winter vegetables are good crops that have a good response to boron fertilizer. If boron is not available, it will affect growth, which has a great impact on yield or quality. Practice has proved that the application of boron fertilizer to winter crops can achieve significant yield increase. It is a measure for increasing production with less investment and effective results.
1. Rape. The lack of boron in rapeseed, atrophy at seedling stage is not long, flowering is not true, and it has a great impact on yield and quality. The application of boron fertilizer can promote the normal growth of rapeseed, increase pods, increase seed setting rate and 1000-grain weight, and increase production by 10% to 20%. The rapeseed application of boron can be applied based on spraying, foliar application and foliar fertilizer spraying. During the transplanting of rapeseed, Koshi was uniformly mixed with 500 grams of borax per acre and then applied into transplanting or transplanting trenches. After the transplanting, 500 grams of borax was added per acre and the roots were sprayed. Shiyi sprayed 0.2% borax solution once at the seedling stage, bud stage and early flowering stage, and the spraying fertilizer solution was 30 kg, 50 kg and 75 kg per mu respectively.
2, broad beans. The lack of boron in broad beans will also produce flowers without realizing the image, affecting high yields. The application of boron fertilizer can reduce the loss of calyx, increase pod and grain weight, and increase production by 15% to 20%. Should be sprayed in the seedling stage, early flowering stage and flowering stage, a concentration of 0.1% borax solution, per acre spray fertilizer solution seedling period of 30 kg to 40 kg, flowering 50 kg to 75 kg.
3, wheat. The lack of boron in wheat seedlings is not normal at the seedling stage, and there is a "spike-not-yet-acting disease" in the later period. There are many empty louses, and the yield is low and the quality is poor. The application of boron fertilizer can increase the seed setting rate, promote the fullness of grain and increase production by about 10%. It is advisable to spray one borax solution with a concentration of 0.05% to 0.1% at the delivery and jointing stages, each time about 50 kg of fertilizer solution per acre.
4, potato. Potatoes (potatoes) are deficient in boron, plant growth points or tips are apt to wither, lateral shoots increase and grow rapidly, and internodes are short, making the plants appear as a short plexus, resulting in a small tuber and a low yield. Soaking seed tuber with a concentration of 0.1% borax solution for 4 hours to 6 hours after sowing can achieve significant yield increase. Can also be sprayed during growth, generally from the seedling stage to budding and flowering stage with 0.1% borax solution spraying 2 or 3 times.
5, green manure. The lack of boron in green manure, poorly developed root nodules, and poor nitrogen fixation make it difficult to obtain high yields. The borax solution with a concentration of 0.2% was sprayed once at the seedling stage, bud stage and early flowering stage, which increased the fresh grass production by more than 20%, and left the field to increase the seed collection by more than 25%.
In addition, winter vegetables such as cabbage, celery, lettuce, beet, radish, etc. are all vegetable crops that are sensitive to boron, and the addition of boron fertilizer can achieve good yield increase and quality improvement. The vegetable boron fertilizer is mainly used for spraying foliar fertilizers. It is advisable to spray 2 to 3 times in the middle and middle period before fertility. Spray 0.1-0.2% borax solution 30 kg per acre. 50 kilograms.
