经过1973—1975年的试验示范看出,在花生根结线虫病严重发病地块,每亩用滴滴混剂60—80斤熏蒸土壤防治花生根结线虫病效果达95.7—98.4%,杀除线虫92.5—98.15%,株高增加40.3—45.8%;产量增加60—127.3%,同时对花生固氮根瘤菌无不良影响,施药区此对照区花生固氮根瘤菌增加161.8-205.3%,而且施药一次后,第二年不再施药,仍有87.6—92.3%的防病后效和25—50%的增产效果。
After 1973-1975 pilot demonstration showed that peanut root knot nematode disease in the block, the mu with drip mixture 60-80 kg fumigation soil pest control root knot nematode disease effect of 95.7-98.4%, kill Nematode 92.5-98.15%, plant height increased 40.3-45.8%; yield increased 60-127.3%, while the peanut nitrogen-fixing Rhizobia no adverse effects, the application of this control area peanut Azotobacter increased 161.8-205.3%, and the application of pesticides Once, the second year no longer applied pesticides, there are still 87.6-92.3% of the disease prevention effect and 25-50% yield increase.
