【Abstract】 A study indicated that the deeply applying (25cm) of chloropicrin with the effective content of 54000g/hm 2 in furrow 30 days before the peanut sowing induced the control effect of peanut root-knot nematode in plots is 90%(83.3%～97.2%) yield increase is 77.03%(69.8%～82.0%) and in demonstratating field is 90.9%(88.1%～94.4%),yield increase is 151.8%(127.9%～172.7%) which showed significant effect on peanut root-knot nematode control and yield incrase.更多还原
