目前,世界上许多国家已普遍使用生物肥料,并正在逐渐加大生物肥料的施用比例,以替代常规化肥。欧洲一些国家的使用量已高达农业用肥总量的45%～60%,美国使用量达农业用肥总量的60%～70%。我国生物肥料的研制开发和生产应用尚处于初始阶段,生物肥料的潜在市场亟待挖掘。生物肥料是以城乡有机废物为原料,配以生物接种剂和其他添加剂,经生物方法制成的高效有机肥通常生物肥料可以分为把空气中的氮固定供豆科作物营养的生物氮肥,把土壤中植物无法吸收的无机磷或有机磷分解成植物能吸收的生物磷肥,以及能把土壤中矿物钾分解成生物钾肥。开发并使用生物肥料,将是保证农产品有效供
At present, biological fertilizers are widely used in many countries in the world, and the proportion of biological fertilizers is being gradually increased to replace conventional fertilizers. Some European countries have used up to 45% to 60% of the total agricultural fertilizers and the United States has used 60% to 70% of the total agricultural fertilizers. China’s biological fertilizer research and development and production applications are still in its infancy, the potential market for biological fertilizers need to be tapped. Biological fertilizer is based on urban and rural organic waste as raw material, together with biological inoculant and other additives, bio-efficient biological fertilizer can be divided into biological nitrogen fertilizer can be divided into nitrogen in the air for the nutrition of legumes biological nitrogen fertilizer, Inorganic phosphorus or organic phosphorus that plants can not absorb in the soil can be decomposed into bio-phosphate fertilizer that can be absorbed by plants, and can decompose mineral potassium in soil into bio-potash fertilizer. The development and use of biological fertilizers will ensure the effective supply of agricultural products
