The reason for zinc deficiency in soil is generally the following conditions. The first is the soil that lacks zinc in the parent material, such as the soil developed by granite; the second is the calcareous soil, and the main components are in the north, including the soils of cotton, bauxite, fluvo-aquic soil, cinnamon soil, brown soil, etc. The PH value of this type of soil Higher zinc content reduces zinc availability and is the main soil for zinc deficiency in China. Third, it contains calcareous paddy soils with high organic matter. The adsorption of organic matter also reduces the effectiveness of zinc. Fourth, excessive application of phosphate fertilizer to soil and Some soils that have limited root development due to harsh environmental conditions are also susceptible to zinc deficiency.
Easy to make some crops produce physiological diseases, if the tree is lack of zinc, the seedlings are hard and small, causing cluster leaves, known as lobular disease; rice zinc deficiency, seat pockets, plant dwarf, delayed tillering, small root system, delayed growth period, empty shell The rate is high; the lack of zinc in maize results in chlorosis of leaves and white flowers, delaying male silking, and lacking of spikes in ears. In addition to rice, corn, and fruit trees that are sensitive to zinc deficiency, flax, wheat, peanuts, soybeans, and peas are also susceptible to zinc deficiency.
Less class, generally use zinc sulfate, zinc oxide and so on. Zinc in soil is the most commonly used method. Spreading and applying can be applied. When applying, combine tillage. Before sowing or transplanting, it is the best time for applying zinc to soil. Generally, about 1.5-5.0 kg/mu (sulfuric acid) is applied. Zinc); foliar spray applied to fruit trees and vegetables, but the emergency measures when the crop appears zinc deficiency symptoms, suitable for early crop growth, the concentration is generally 0.05-0.1% of zinc sulfate, fruit trees available 0.5% zinc sulfate solution Seed treatment with 0.1% zinc sulfate solution soaked or used as rice, cotton and other seed coating; and with 2-4% zinc oxide suspension is a cost-effective method. If zinc sulphate is used for the acid hydrolysis of industrial waste, attention should be paid to the pollution of heavy metals such as cadmium and lead. The residual effect of zinc in the soil is generally 3-5 years, and the soil can be rooted. The results of plant analysis determine whether to apply zinc fertilizer.
