生物有机肥对冬瓜枯萎病及土壤微生物和酶活性的影响
Effects of biological organic fertilizer on wax gourd wilt disease, microorganism and enzyme activities in soil
摘要
Abstract
[Objective]To research the effects of the biological organic fertilizer ( BOF) on controlling wax gourd wilt disease , microorganism and enzyme activities in soil .[Method]The biological organic fertilizer (BOF) was made by mixing the mature compost with functional bacteria in proportion to identify the effects in pot experiment .[Result and conclusion]The occurrence of wax gourd wilt disease decreased by applying BOF , and along with the increasing amount of fertilizer application , the efficacy was more signif-icant.When the disease-control effect of CPC treatment was assigned as 0, the disease-control effects of the treatments of BOF1,BOF2 and BOF3 were 42.27%,52.92% and 70.15%, respectively, which were higher than that of disease-control effect(31.91%)of organic fertilizer treatment;With the same a-mount of effective nutrients , the height , stem diameter , leaf width , and fresh mass of plant in BOF 2 treatment were significantly higher than that of OF treatment , which indicated that the BOF could promote the growth of wax gourd .The number of bacteria and actinomycets in soil increased significantly by BOF , while the amount of fungi and Fusarium oxysporum in soil decreased .Urease , acid phosphatase , catalase and invertase activities in soil of BOF were higher than those of CK and CPC treatment .The results showed that BOF could improve soil enzyme activities , adjust soil microbial community structure , improve the soil quality and fertility conditions , hence decrease the occurrence of the wax gourd wilt disease .关键词
