生防放线菌ZZ-9颗粒剂的研制及对黄瓜立枯病的防治效果
Research of Biocontrol Actinomycete ZZ-9 Granules and Its Effect on Cucumber Rhizoctonia Rot
摘要
Abstract
Streptomyces rochei ZZ-9 is a biocontrol strain that with broad-spectrum antifungal activity.The mycelium growth rate method was utilized in this work to screen carriers,stabilizers,disintegrants,adhesives,and wetting agents.The optimal formula of Streptomyces rochei ZZ-9 granules were:the ratio of bacterial solution and attapulgite was 2:5,calcium carbonate 1%,magnesium chloride 2%,polyvinyl alcohol 1%,sodium dodecylbenzene sulfonate 0.5%.The effective viable number of ZZ-9,particle size,moisture content,disintegration time in water,pH value and hardness were 1.19×108 cfu/g,93.5%,2.5%,96 s,6.35 and 10%.The results of pot experiment showed that the optimal controlling effect of cucumber Rhizoctonia rot was 76.92%after application of ZZ-9 granule with 3 g/pot.In addition,the Streptomyces rochei ZZ-9 granules presented significant promoting effects in pot experiment.Compared with the control,the germination rate,plant height,root length and fresh weight of cucumber seedlings were increased by 9.34%,29.52%,27.54%and 22.96%after application of Streptomyces rochei ZZ-9 granules,respectively.关键词
