摘  要:
利用Sr18真菌的代谢物在保护地 (大棚 )对番茄根结线虫病的防治进行了研究 ,结果表明 ,施药后 2 8d取样调查 ,植株高度较对照增加 14 5 % ,证实该菌代谢物对番茄植株无毒害作用 ;可明显降低土壤中根结线虫二龄侵染幼虫的数量 ,线虫减退率为 6 8 2 %。收获末期调查 ,Sr18菌液处理的病情指数较对照降低 4 6~ 5 5个百分点 ,防治效果非常显著 ,并可显著增加番茄产量 ,增产率为 6 1 72 %。

摘  要:
The Sr18 fungal metabolites were used in controlling tomato root knot nematodes (Meloidogyne. sp.) in the greenhouse.The results showed that the metabolites of Sr18 could increase plant height by 14 5%,which means that it did no harm on the tomato plant,and that,it could also reduce the number of second stage juvenil(J2) of tomato root knot nematodes by 68 2%.The result of investigation at harvesting period showed that the control effect was significant and the tomato yield increased by 61 72%.These results indicated that Sr18 fungus could be a prospective strain to develop a new kind of biological control agent for nematodes.
