生物有机肥对大豆红冠腐病及土壤酶活性的影响
Effect of Biological Organic Fertilizer on Soybean Red Crown Rot and Soil Enzyme Activities
摘要
Abstract
Soybean red crown rot is a kind of soil-borne disease, its spread has affected the normal development of soybean industry. In this study, biological organic fertilizer(BOF) made by the decomposed manure with three kinds of bacteria(Bacillus subtilis ,B. mucilaginosus and B. megaterium) was used to control the soybean red crown rot by pot experiment. The results indicated that BOF could significantly reduce the occurrence of the soybean red crown rot. When the disease-control effect of CPC( C.parasiticum Crous ) treatment was assigned as 0, the disease-control effect of two kind of BOF treatments reached 84.74% and 81.30% respectively, which were higher than that of organic fertilizer(OF) treatment disease-control effect(24.24%). In the same effective nutrient,the plant height, fresh weight, dry weight and main stem sections of soybean in BOF treatment were higher than that of OF treatment significantly, which indicated the BOF promotion of the growth of soybean significantly. Application of BOF, soil urease, phosphatase, catalase and invertase activities were higher than those of CPC , CK and OF treatments. The results showed that BOF could improve soil enzyme activities, the soil quality and fertility conditions and prevent the occurrence of soil born disease.关键词
