棉隆熏蒸土壤消毒后对土传病害防治效果的影响研究

Study on the Effect of Soil Disinfection on Soil-borne Diseases Control after Dazomet Fumigating

[目的]了解98%棉隆对保护地土传病害的防治效果,为保护地土传病害防控提供科学依据和技术支持。[方法]通过应用不同浓度的棉隆对大棚土壤进行消毒,对主要土传病害进行数据分析和产量调查。[结果]施用25 g/m^(2)棉隆即可达到理想效果。[结论]棉隆土壤消毒剂对防治番茄织球壳菌萎蔫病、茄子黄萎病、辣椒疫病、根结线虫等土传病害均能取得良好效果,可显著提高作物产量。

[Objective]The aim of this experiment was to study the effect of 98%dazomet on the control of soil-borne diseases in the protected areas,hence providing scientific basis and technical support for soil-borne diseases prevention and control in the protected areas.[Method]The major soil-borne diseases were tested by analyzing of the data and investigating of the average output following by using different concentrations of dazomet to disinfect the soil in greenhouse.[Result]The most ideal effect is proved to be achieved by the concentration of 25 g/m^(2)dazomet.[Conclusion]Soil disinfection by dazomet has good effects on the control of soil-borne diseases such as tomato Plectosphaerella cucumerina(Lindf.)W.Gams,eggplant Verticillium wilt,pepper Phytophthora blight and Meloidogyne incognita,which can significantly increase the yield of crops.
