有机无机复混肥是肥料产业发展中的新秀,具有中国特色,逐渐被产业界所重视。过去发展有机无机复混肥料的主要原因,一是消纳有机废弃物,保护环境;二是增加土壤有机质,培肥土壤。以上两个方面固然是促进有机无机复混肥料发展的重要动力。然而,我们一系列的研究发现,有机物料与化学肥料科学复合(混),具有调节化学肥料养分转化、释放和供应模式的作用,有机物料通过改善土壤的理化性状、调节土壤酶活性等,减轻氮肥氨挥发损失,减缓磷钾肥在土壤中的固定,土壤供肥能力得到改善,等养分投入条件下, Organic-inorganic fertilizer is a rookie in the development of fertilizer industry, with Chinese characteristics, gradually by the industry attention. In the past, the main reasons for the development of organic-inorganic compound fertilizers are to eliminate organic wastes and protect the environment; second, to increase soil organic matter and fertilize the soil. The above two aspects of course is to promote the development of organic and inorganic compound fertilizer an important driving force. However, our series of studies have found that the scientific compounding (mixing) of organic materials with chemical fertilizers has the effect of regulating the mode of nutrient conversion, release and supply of chemical fertilizers. Organic materials can reduce the physical and chemical properties of soil and regulate the activity of soil enzymes Nitrogen ammonia volatilization loss, slowing the fixation of P and K in the soil, improving soil fertility, and under the conditions of nutrient input,
