有机肥是无机化肥所不可替代的重要肥类,它不仅是矿质元素的重要来源,而且是有机质的主要来源.由它腐殖化而形成的腐殖质,对种子萌发、根系生长、光合作用和植物养分的有效性都有重要的作用,而且对土壤水气肥热等有重要的调节和缓冲作用.同时,它是土壤中微生物能量的重要来源,微生物在分解有机肥所产生的腐植酸、酶、生长激素对土壤中物质和能量转化起重要作用.它形成的腐殖 Organic fertilizers are important fertilizers that can not be replaced by inorganic fertilizers, which are not only the important source of mineral elements, but also the main source of organic matter. The humus formed by humification is good for seed germination, root growth, photosynthesis and plants Nutrient availability has an important role, but also on soil moisture and other important heat regulation and buffering effect.At the same time, it is an important source of microbial energy in soil, microorganisms in the decomposition of organic manure generated by humic acid, enzyme , Growth hormone plays an important role in the conversion of matter and energy in the soil, and it forms humus
