Effects of Fertilization on Strawberry Fusarium Wilt and Soil Microbial Communities Under Continuous Mono-cropping
摘要
Abstract
Soil nutrient management is recently an attractive method to control soil-borne plant disease. A field plot experiment with different fertilization treatments was carried out to evaluate the effects of fertilization on disease resistance of strawberry and soil microbial communities in continuous mono-cropping field of strawberry, by using microbial cultivation and Biolog analysis. The results showed that strawberry plant growth could be improved and strawberry rosarium wilt was controlled effectively under optimized fertilization treatments. In addition, the proportion of culturable bacterium and actinomycctes to fungus under optimized fertilization 1 were increased when compared with conventional fertilization treatment The Biolog analyses indicated that optimized fertilization treatments had less affects on the carbon utilization ability and Shannon, Simpson, Mcintosh indexes of soil microbial communities in a short term. PCA analyses suggested that carbon utilization of soil microbial communities under optimized fertilization I was obviously different from that of conventional fertilization treatment. Considering control of strawberry Fusarium wilt and dosage of fertilizer, optimized fertilization I was more effective and economical treatment than optimized fertilization II.关键词
