黑龙江省李子园杂草发生种类多、密度大,对李子树生长发育危害较重,对产量也有明显影响。人工除草费工、劳动强度大,又很不经济。为寻求经济、安全、有效地防除李子园杂草的方法,我们选用草甘膦,于1987～1988年进行2年试验,通过试验取得了相当好的除草效果。 Weeds in the plum garden in Heilongjiang Province have many types and densities, which are harmful to the growth and development of plum trees and have a significant impact on the yield. Manual weeding workers, labor-intensive, very uneconomical. In order to find out the economical, safe and effective method to control the weeds in plum garden, we chose glyphosate for two years from 1987 to 1988, and achieved quite good weeding effect through experiments.
