摘要
用石灰氮颗粒剂(有效成分为氰胺化钙)进行了处理温室土壤防治番茄根结线虫试验。试验结果表明,石灰氮颗粒剂可较好地控制番茄根结线虫为害。石灰氮3.3,5.0,6.7kg/667m23个处理,药后90天土壤中2龄幼虫数量减退率分别为16.85%,31.58%和61.54%,而对照药剂1.8%阿维菌素乳油1.0L/667m2处理的线虫减退率为37.28%。药后90天石灰氮颗粒剂各处理防治效果分别为60.00%,66.00%和73.72%,而对照药剂为61.99%。石灰氮颗粒剂可有效地控制番茄根结线虫的为害,有较高的推广应用价值。
CaCN2 was used to control tomato root-knot nematode in greenhouse soil. The results showed that CaCN2 was an excellent nematicide for controlling tomato root-knot nematode. The decline rate of J2 was 16.85%, 31.58% and 61.54% by CaCN2 applied at 50, 75, 100 kg/hm2, respectively while Avermectin was 37.28% after 90 days. The control effect was 60.00%, 66,00% and 73.72% by CaCN2 applied at 50, 75, 100 kg/hm^2 , respectively while Avermectin was 61.99% after 90 days. These results indicated that CaCN2 could be a prospective nematocide for tomato root-knot nematodes control.
