Rational fertilization is an important measure to achieve high yield, stable production, low cost and environmental protection. It is necessary to apply phosphorus to the soil and to see the ground quantitatively; according to the requirements of various crops for fertilizer, reasonable application; master key and suitable nitrogen application; deep application of fertilizer, fertilizer and efficiency; organic fertilizer and inorganic fertilizer.
The organic fertilizer has full nutrients and slow fertilizer efficiency; the fertilizer is rich in fertilizer and quick in effect. In particular, organic fertilizers contain a large amount of organic matter, which forms humus by microbial action, can improve soil structure, make it loose and soft, and has good ventilation. This not only benefits the growth and development of crop roots, but also helps to improve soil water retention and fertilizer retention. ability. Fertilizer can supply the available nutrients needed for microbial activities, accelerate microbial growth and activity, promote the decomposition of organic fertilizers, and release a large amount of carbon dioxide and organic acids, which is beneficial to the dissolution of poorly soluble nutrients in the soil. Therefore, the combination of organic fertilizer and chemical fertilizer can take advantage of the length and complement of each other and give full play to the effects of these two fertilizers.
