近年,日本农用土壤微生物制剂改变了单一菌种做法,向着复合菌种发展,从而达到一菌多用的目的。一九六九年,合成的新制剂“利王”便是其中之一。其主要成分为真菌、放线菌和细菌。此外,尚有27％硅酸、30％苦土石灰、20％有机质及其他添加物。“利王”能改良土壤,防止肥料流失,又能杀菌防虫,同时还能提高作物品质和产 In recent years, Japan’s agricultural soil microbial agents have changed the practice of a single strain toward the development of complex strains, so as to achieve the purpose of multipurpose bacteria. In 1969, one of them, the new synthesis “Lee King,” was one of them. Its main components are fungi, actinomycetes and bacteria. In addition, there are 27% silicic acid, 30% bitter lime, 20% organic matter and other additives. “Lee King” can improve the soil, prevent fertilizer loss, but also bactericidal pest control, but also improve crop quality and production
