几种微生物菌剂对辣椒混合性土传病害的田间防效试验

用不同浓度的微生物茵剂AR156、AR156—1、AR156—2、菌根菌、甲基硫菌灵喷洒基质，研究不同浓度处理对辣椒栽培大田土传病害的防效。研究结果表明，辣椒移栽后60d和105d，浓度为10。cfu／mL的AR156—2处理的防效分别为86．39％和78．14％，增产效果显著，增产率214．39％；菌根菌防效不明显，但促生效果明显，增产率达158．25％。

Control Efficacy of Several Microbial Agents against Mixed Soil-borne Diseases of Hot Pepper in Fields

In this study, we mixed the microbial agents AR156, AR156-1, AR156-2 which were came from Nanjing Agricultural University, mycorrhizal fungi which was came from Qingdao Agricultural University, fungicide thiophanate- methyl which was came from the German Basf Inc. with pepper matrix respectively, and studied the control efficacy of different agents with different concentrations against soil-borne diseases of hot pepper in fields. The results showed that, the treatment 10^8 cfu/mL AR156-2 possessed highest control efficiency of 86.39% and 78.14% after hot pepper plants being transplanted 60 days and 105 days later respectively, and the yield was significantly increased by 214.93%. The myeorrhizal fungi treatment did not show so significant eontrol effect as the agent AR156-2, but the yield was increased by 158.25%.
