Pay attention to applying zinc fertilizer to crops
Zinc deficiency in soil is very common. In general, zinc deficiency is likely to occur in areas with high groundwater levels, winter fields, muddy fields, high altitudes, and low temperatures. The use of a large amount of compound fertilizers and phosphate fertilizers can induce zinc deficiency in crops and require the addition of zinc fertilizers. The application of hybrid varieties and high-yield cultivation techniques results in a greater amount of zinc for the crops and an additional application of zinc fertilizer. The use 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 zinc fertilizer application method is as follows:
1. Paddy soil: The amount of large-grain zinc per acre is 200 g. It can be used as seedbed fertilizer in Putian, combined with site preparation for surface fertilizer, and the large-grain zinc is mixed with granular fertilizer and fine soil and then distributed.
2. Dryland Soil: Use 200 grams per acre of large grain zinc. Before planting the ground, combine large-grain zinc with compound (mixed) fertilizer or fine soil, spread, apply or apply.
3. Application of fruit trees: The amount of large-grain zinc in each fruit tree is 5 to 10 grams (10 to 30 grains, based on the size of the crown). It can also be used together with compound fertilizer and organic fertilizer, as a spring fertilizer, strong fruit fertilizer, and also as a positive fertilizer. Application, along the tree crown along the drip line after the application of the trench.
In addition, it should be noted that it is advisable to apply zinc fertilizer sooner rather than later, and it is best applied in the early stage of crop growth. Zinc fertilizer should be combined with nitrogen, phosphorus and potash fertilizers in order to exert greater fertility and obtain a better harvest. Zinc fertilizer should be strictly controlled and applied according to the recommended amount. Large grain zinc has a post-effect, and zinc deficiency fields can be applied once a year or every other year.
