摘要
利用筛选获得的对植物线虫具有毒杀活性的光合细菌菌株和芽孢杆菌菌株培养液及其混配制剂进行防治黄瓜根结线虫病田间药效试验。试验结果表明,3种菌剂对黄瓜根结线虫病都有一定的防治效果,能显著降低黄瓜根围根结线虫J2虫口密度,减少根结的形成,尤其是两菌剂复配后作用效果显著优于两单剂,说明两生防菌剂具有协同效应。同时研究结果显示,3种生防菌剂还能促进植物生长,显著提高作物产量。
In this paper, the fermentation broth of photosynthetic bacteria and Bacillus spp. and their mixture were used for the control of cucumber root-knot nematode (Meloidogyne incognita) in field. The results showed that, the three fermentation broth could decrease the number of second stage juvennil (J2) of root-knot nematodes and reduce the galls formation. The results showed that these two bio-uematicides were effective especially the they were mixed, which indicated that the two biocontrol bacteria had synergistic effects. The results also showed that the three treatments could promote plant growth and increase the yield.
