不同土壤处理剂对设施蔬菜黄瓜根结线虫防治技术研究

Control effect of different nematicides to the root-knot nematodes in greenhouse cucumber

为了筛选蔬菜根结线虫的防治技术,在赤峰市进行了7种不同土壤处理药剂对黄瓜根结线虫的防治效果田间试验,结果表明,应用7种不同土壤处理药剂进行土壤处理,揭膜放气5d后定植黄瓜,对黄瓜生长无不良影响,而且对根结线虫均有较好的抑制作用,其中98.1%1,3-二氯丙烯-氯化苦复配胶囊16kg/667m2、95%1,3-二氯丙烯液剂65kg/667m2及10%液体石灰氮65kg/667m2对黄瓜根结线虫的防治效果达90%左右,优于目前生产中常用药剂42%威百亩水剂6kg/667m2和10%噻唑磷颗粒剂2kg/667m2的防治效果,并且可以显著地提高黄瓜产量,适于在设施蔬菜生产上推广使用。

The field experiment was conducted to define the control effect of seven kinds of soil treatment agents on the root-knot nematode in greenhouse cucumber in Chifeng City. The results showed that soil treated by seven kinds of different soil treatment agents had no negative effect on the growth of cucumber plants, but had good in- hibition against root-knot nematodes. Control effects of 98.1% 1,3-dichloropropene-chloropicrin mixture capsule with dose of 16 kg/667 m^2 , 1,3-dichloropropene LD with dose of 65 kg/667 m^2 and 10% liquid calcium cyanamide with dose of 65 kg/667 m^2 were about 90%. These treatments could increase the yield of cucumbers and had better control effect than that of the common chemicals, 42% metam-sodium AS 6 kg/667 m2 and 10% fosthiazate GR 2 kg/667 m^2.
