The phenomenon of zinc deficiency in the soil is very common. In general, high groundwater levels, winter soaking fields, muddy fields, high altitudes, and low temperature areas are all prone to zinc deficiency. A large amount of compound fertilizer and phosphate fertilizer will induce zinc deficiency in crops, and zinc fertilizer needs to be added. The application of hybrid varieties and high-yield cultivation techniques has resulted in a larger zinc requirement for crops and an increase in zinc fertilizer. The application of zinc fertilizer in corn, wheat, cotton, rape, fruit trees, vegetables, soybeans, peanuts, artichokes, tobacco and other crops can significantly improve and improve product quality.
The method of applying zinc fertilizer is as follows:
1. Paddy soil: The amount of large-grain zinc per acre is 200g, which can be used as a seedbed fertilizer in the field. Combine with the soil preparation as a noodle fertilizer, mix the large-grained zinc with granular fertilizer and fine soil and then apply it.
2. Dryland soil: 200g of large-grained zinc per acre. Before planting the soil, mix the large-grained zinc with the compound (mixed) fertilizer or fine soil, then apply it, apply it or apply it.
3, fruit tree application: the amount of large zinc per fruit tree is 5 ~ 10 grams (10 ~ 30, according to the size of the canopy), can also be applied with compound fertilizer, organic fertilizer, as a spring fertilizer, strong fruit fertilizer, also Yang fertilizer Application, the tree crown is applied along the drip line to cover the soil.
In addition, it should be noted that the application of zinc fertilizer should be applied sooner or later, and it is best applied in the early stage of crop growth. Zinc fertilizer should be combined with nitrogen, phosphorus and potassium fertilizers to exert greater fertilizer efficiency and obtain a better harvest. The application of zinc fertilizer should be strictly controlled and applied according to the recommended amount. Large zinc has an aftereffect, and zinc-deficient fields can be applied once a year or every other year.

Pay attention to applying zinc fertilizer to crops
Zinc deficiency in crops is one of the most common micronutrient deficiencies. Its common features are: chlorosis of leaves, shortening of internodes, clusters, small leaves, short plants, growth inhibition, high seed emptying rate and low yield. The solution is to apply zinc fertilizer. Once zinc is added, the growth and development of the crop will be significantly improved, the seed setting rate can be improved, the cold resistance and disease resistance can be enhanced, and the yield can be increased by 10% to 30%.
