The quality of the role of bio - fertilizer
From the way bio-fertilizers can be learned, bio-fertilizers can not directly provide nutrients (including nitrogen, phosphorus, potassium and various mineral elements) that are absorbed by the crop, but are produced by a large number of active microorganisms in the soil. Assisting the crop to absorb nutrients or produce growth hormone to stimulate the growth of the crop, which is essentially different from the way the fertilizer is applied. And bio-fertilizer can provide fertilizer efficiency can not meet the needs of crop growth on nutrients. Therefore, the view that bio-fertilizers can replace fertilizers is a misunderstanding, and some of the biological fertilizer mysterious, known as "high-tech" products, infinitely exaggerated its role is also wrong in the use of bio-fertilizer in agricultural production and The use of fertilizers should complement each other. But bio-fertilizer is not environmental pollution, is conducive to the protection of the ecological environment, and some of the role of bio-fertilizer and ecological benefits are not available or irreplaceable fertilizer.
Bio-fertilizer can improve soil fertility, which is its main role, such as various nitrogen-fixing bacteria fertilizer, can increase the nitrogen source in the soil, the solution of phosphorus and potassium fertilizer can dissolve the soil insoluble phosphorus and potassium, Soil phosphorus (P), potassium (K) elements of the source. In addition, bio-fertilizers can promote crop growth and improve the quality of agricultural products. A variety of bio-fertilizer into the soil, can produce different growth hormone, stimulate the growth of crops, such as "5406" actinomycetes bio-fertilizer, not only antagonize the role of pathogens disease prevention bacteria, but also secrete cytokinin Crop growth. Fungal bio-fertilizer not only in helping crops to absorb phosphorus, zinc and copper and other mineral elements have a strong role, as well as enhance the crop of water, water to improve the role of crop drought resistance. As the bio-fertilizer can produce and help the crop to absorb the use of a variety of nutrients, so the quality of agricultural products have greatly improved, can change the fertilizer produced by the "melon is not fragrant, fruit is not sweet, tea tasteless" status, The indicators to meet the green food standards.
