Chemical fertilizers are characterized by simple ingredients, high nutrient content, low dosage, fast fertilizer efficiency, convenient application, transportation and storage, and can quickly increase yield and quality. Phosphorus and potassium fertilizers can be divided into single fertilizers, compound fertilizers and mixed fertilizers. Elemental fertilizers contain one element, such as ammonium sulfate, ammonium bicarbonate, urea, etc., containing only one element; compound fertilizers contain two or three elements, such as ammonium phosphate, potassium nitrate; mixed fertilizers, such as ammonium sulfate Fertilizer mixed with superphosphate.
Nitrogen fertilizer is a fertilizer for nitrogen nutrients needed for plant growth. It is an important substance that constitutes plant protein. Plant chlorophyll, phospholipids, glycosides, nucleic acids, vitamins and alkaloids all contain nitrogen, and nitrogen fertilizer is appropriate. Mao, the production of organic matter, the role of increasing yield and quality is great; if improperly applied or applied too much, it will cause stems and leaves to grow wild, easy to fall, increase disease, hinder flowering, delay crop maturity, and reduce production.
Phosphate fertilizer is a fertilizer for phosphorus nutrients needed for plant growth, and can be divided into natural phosphate fertilizer and artificial phosphate fertilizer. Appropriate application of phosphate fertilizer has a good effect on root development, can promote crop torso robust, not easy to fall, enhance drought resistance, cold resistance, disease resistance, and promote flowering and fruiting, so that crop seeds are full, commonly used and used in larger amounts of nitrogen.
Potassium fertilizer is a fertilizer for potassium nutrients needed for plant growth. Appropriate application of potash fertilizer can make grain kernels full, promote the increase of roots such as potatoes and potatoes, and increase sugar by fruits, sugar cane and sugar beet, etc. Crop tillers increase. It can make the stems of plants strong and not easy to fall, and enhance the ability of drought resistance, cold resistance and disease resistance.
