1种类利用农业、工业和畜牧业的废弃物或有机垃圾、城市污泥,经有益微生物发酵、加工而成的有机肥料称为生物有机肥料。生物有机肥料含大量有机质和大量活的有益微生物及微生物代谢产物,兼有微生物接种剂和有机质,活菌数定为≥0.2亿个/克,有机质含量≥35%。(1)作物秸秆腐熟剂和畜禽粪便、有机垃圾发酵剂。(2)微生物接种剂指利用已知的有益微生物经液体发酵生产而成的液体活菌制品,或菌液经无菌载体吸附而成的固体活菌制品。生物肥料的产品质量不稳定是微生物接种剂生产中存在的最主要问题。
1 types of organic fertilizers made from organic, industrial wastes and organic wastes, municipal sludge and fermented and benefited microorganisms are called bio-organic fertilizers. Bio-organic fertilizer contains a large amount of organic matter and a large number of live beneficial microorganisms and microbial metabolites, both microbial inoculum and organic matter, the number of viable cells is set at ≥0.2 billion / g and the organic matter content is over 35%. (1) Crop stalks and livestock manure, organic waste starter. (2) Microbial inoculants refers to solid viable products made from liquid viable bacteria produced by liquid fermentation of known beneficial microorganisms, or by bacterial cells adsorbed by a sterile carrier. The instability of the product quality of biological fertilizers is the most important issue in the production of microbial inoculants.
