【正文】 料就是利用天然肥料資源菌，通過提高、改造其生產性能，對其進行工業(yè)化生產的肥料。我國是化肥生產消費第一大國，但由于長期的不合理施用，已造成肥效急劇下降、生產成本上升、環(huán)境污染、土壤板結、可耕作性惡化[2]。與施用化學肥料相比，微生物肥料不僅具有肥效好、肥效長、作物體內無殘留毒素、無副作用、不污染環(huán)境、成本低、經(jīng)濟效益高、用途廣泛等諸多優(yōu)點，還能保育、改良土壤、提高土壤肥力、防止環(huán)境污染和土壤惡化，建立起高產農田的良好生態(tài)系統(tǒng)，進而促進農業(yè)的可持續(xù)發(fā)展[1]。 organic farming。Summary: In recent years to, in agricultural production in the due to abuse fertilizer, soil aggregate structure suffered damage, soil of insurance fertilizer insurance water capacity weakened, soil is serious pollution, microbial normal District of is disrupted, to force declined, crop pest increasingly serious, and fertilizer of loss and volatile and pollution has water and air, caused ecological of evil cycle, on human survival and health brings potential threat. Therefore, under pressure from resources, environment, energy, and required the development of sustainable organic agriculture and microorganism fertilizer. Microbial fertilizers are metabolites of microorganisms life activity and its role in improving crop nutrient supply, providing nutrients to crops, growth substances, which regulates its growth, to improve the yield and quality, reducing fertilizer use, improve soil fertility, reduction or reduction of plant diseases and insect pests, improve environmental quality. Key words: Fertilizer。微生物肥料是利用微生物的生命活動及其代謝產物的作用，改善作物養(yǎng)分供應，向農作物提供營養(yǎng)元素、生長物質，調控其生長，達到提高產量和品質、減少化肥使用、提高土壤的肥力、減少或降低病蟲害發(fā)生、改善環(huán)境質量。微生物肥料與有機農業(yè)20116432摘要：近些年來，在農業(yè)生產中由于濫用化肥，土壤團粒結構遭受破壞，土壤的保肥保水能力減弱，土壤被嚴重污染，微生物正常區(qū)系被打亂，地力下降，作物病蟲害日趨嚴重，并且化肥的流失和揮發(fā)又污染了水源和空氣，引起生態(tài)的惡循環(huán)
