土壤添加剂是一种有机、无机营养混合物 ,是防治作物病害的一项重要措施 ,国内外对此均有研究报道。土壤添加剂的防病机制综合为无机盐的抑菌作用、有益微生物的拮抗作用、营养物质的促长作用、有机物质增强土壤病原菌的腐生性 ,削弱其致病性。利用土壤添加剂与其他防治方法相比有很多优点 ,其应用前景广泛 Soil additive is a kind of organic and inorganic nutrient mixture, which is an important measure to prevent crop diseases. Both of them have been reported at home and abroad. The combination of soil anti-pathogenic agents for the anti-bacterial effect of inorganic salts, beneficial microbial antagonism, the role of nutrients to promote growth, organic matter to enhance the saprophytic soil pathogen, weakening its pathogenicity. The use of soil additives compared with other control methods has many advantages, its wide application prospects
