White diamond or hexagonal crystal is easy to dissolve in water, has small hygroscopicity, belongs to physiological acid fertilizer, and has strong quick action. After being applied to soil, potassium (K+) is dissolved in soil solution and exists in an ionic state, and can be selectively absorbed by plants or adsorbed by soil colloid. After adsorption, caSO with low solubility is formed in calcareous soil 4 Formation of H in acid soil 2 SO 4 . Thus, the acidification of the soil is less than the HCl formed after potassium chloride application. Is suitable for various soil and crops, but should be preferentially distributed to crops like tobacco, potato, grape, flax and the like which are potassium-like and chlorine-like. Can be used as base fertilizer, additional fertilizer, seed fertilizer and external root fertilizer. The application should be divided into several times on sandy soil to avoid leaching of potassium. On acid soil, the fertilizer should be applied in combination with alkaline fertilizers such as lime to prevent further acidification of the soil and influence on plant growth. The potassium sulfate is an important variety in potash fertilizer, is a high-quality fertilizer, has a saline-alkali soil index of only about 40% of that of potassium chloride, and is particularly suitable for some commercial crops such as tobacco, watermelons, tea, oranges, grapes and the like which are free of chlorine. The potassium sulfate can not only improve the crop yield, but also improve the quality of the crops, and can improve the disease resistance of the crops when used for sulfur-deficient soil.
At present, the main methods for producing potassium sulfate are as follows: man Ha Mfa, association method, double decomposition method, etc. Wherein, man Ha Mfa is a process for producing potassium sulfate by using sulfuric acid and potassium chloride as raw materials.
