Zinc deficiency in crops is a common micronutrient deficiency. Its common features are: leaves are chlorotic, internodes are shortened, clusters, small leaves, short plants, growth inhibition, high seed empty rate, low yield, the solution is Apply zinc fertilizer. Once the zinc is supplemented, 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 more than 10%.
The phenomenon of zinc deficiency in the soil is very common. 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 on corn, wheat, cotton, rape, fruit trees, vegetables, soybeans, peanuts and other crops can significantly improve and improve product quality.
Zinc fertilizer can generally be used as base fertilizer, top dressing and seed fertilizer in application.
1, base fertilizer. When zinc fertilizer is used as the base fertilizer, 1-2kg of zinc sulfate is generally applied per mu, which can be mixed with physiological acid fertilizer. The mild zinc-deficient plots are applied again after 1-2 years, and the moderately zinc-deficient plots are applied every other year or in the following year.
2, topdressing. When zinc fertilizer is used as top dressing, it is often used as top dressing. The general crop is sprayed with a concentration of 0.02%-0.1% zinc sulfate solution, and the corn can be used at a concentration of 0.1%-0.5%. The fruit tree can be sprayed with 5% zinc sulphate one month before the germination, and the germination result tree is brushed with 3%-4% concentration; the annual branches are 2-3 times or 0.2% zinc sulphate solution is sprayed in the early summer.
3, seed fertilizer. Zinc fertilizer is often used for soaking seeds or seed dressing methods. The concentration of soaking seeds is 0.02%-0.1%, soaking seeds for 12 hours, and sowing after drying. For seed dressing, use 2g-6g zinc sulfate per kilogram of seed, and corn can use 2g-4g.
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.
