| 摘 要： | 利用放线菌1306、1342、1384的发酵液对蒙自枣树根际土壤线虫进行致死性研究，并根据谢辉分类系统，对致死线虫进行种类鉴定。结果表明：菌株1342发酵液的5个稀释倍数在48 h后对线虫的校正死亡率均达到了50%以上，杀线活性级别达到A级；菌株1384的100%、80%、20%发酵液在48 h后杀线活性级别为A级，40%、60%发酵液在48 h后杀线活性级别为B级；菌株1306的40%、60%发酵液在48h后杀线活性为B级，其余3个稀释倍数的杀线活性为C级。所以，3种放线菌发酵液中，1342和1384对线虫的致死性较好。对致死的线虫进行了种类鉴定，它们分别是燕麦真滑刃线虫（Aphelenchus avenae）、孤独滑刃线虫（Aphelenchus eremitus）、螺旋拟滑刃线虫（Aphelenchoides helicus）、异头丝尾垫刃线虫（Filenchus heterocephalus）、细尾盘旋线虫（Rotylenchus tenericaudatus）、多带螺旋线虫（Helicotylenchus multici nctus）等。

| Abstract: | The three fermentation broths of 1306, 1342 and 1384 were used in the lethal study of nematodes in rhizosphric soil of Ziziphus jujuba in Mengzi, according to Xie's classification system, we identified the species of killed nematodes. The result showed that:in 48 hours treatment, all the fermentation broths of 1306, 1342 and 1384 had certain lethal effect on nematodes at different dilution ratios. In 48 hours treatment, the 5 dilution ratios of the 1342 fermentation broth showed the lethal efficiencies to more than 50%, and the activated level was A. The activated level of 1384 fermentation broth in the dilution ratios of 100%, 80%, 20% was A after 48 hours, and the dilution ratios of 40%, 60% was B. The activated level of 1306 fermentation broth in the dilution ratios of 40% and 50% was B, and the rest 3 dilution ratios were C. Therefore, among the 3 fermentation broths, the lethal effects of 1342 and 1384 were better. The identification result showed that the species of killed nematodes belong to Aphelenchus avenae, Aphelenchus eremitus, Aphelenchus helicus, Filenchus heterocephalus, Rotylenchus tenericaudatus, and Helicotylenchus multicinctus, etc. |
