复合微生物菌剂对生菜根结线虫田间防治效果
Field Experiment of Multi-microbial Agents against Root-knot Nematode Meloidogyne incognita on Lettuce
摘要
Abstract
In order to study the effect of multi-microbial agents,which was consisted of Purpureocillium lilacinum,Streptomyces olivaceus and Ochrobactrum pseudogrignonense,on root-knot nematodes in lettuce field,the experiment was conducted in a greenhouse with the commercial multi-microbial agent,which was mainly consisted of P.lilacinum,turfy soil and 10％ fosthiazate granules as controls.The results showed that the 10％fosthiazate had the best effect up to 78.2％ on lettuce root-knot nematode.The effect of multi-microbial agent on lettuce root-knot nematode at 44 d was 34.9％,which was significantly superior to the commercial multi-microbial agent,tufty soil and the untreated control.Meanwhile,the application of multi-microbial agent could also promote plant growth.Both the fresh weight and the height of the multi-microbial agent treatment were significantly higher than the commercial multi-microbial agent,tufty soil and the untreated control.The total yield of multi-microbial agent treatment was also higher than other four treatments with the improvement of 47.2％.The results indicated that the multi-microbial agent could not only effectively control the lettuce root-knot nematode,but also improve the growth of the plant and the yield.Although the effect of the multi-microbial agent was not as good as the 10％ fosthiazate,it gave us a newly effective and safe way to control root-knot nematodes on those leafy vegetables with short growth period.关键词
