摘要
应用农业的、生物的、物理的方法和无公害农药等技术措施,综合防治山楂多种病虫害。防治效果一般比常规方法提高30%～60%,天敌数量增加48.23%,农药成本降低51.26%～68.51%,产量提高47.58%。农药残留的检测结果:检不出或低于FAO/WHO或国家标准500～1000倍。
Field experiments on integrated control of pests injuring Chinese hawthorn by some nonpollution techniques including agricultural, biological and physical methods, were carried out in Xinglong County, Hebei Province during 1989～1991. Satisfactory results were obtained. Compared with synthetic pesticides, the new techniques improve the control effect by 30%～60% generally, increase the number of natural enemies by 51.26%～68.51%, and enhance the yield by 47.58%. The test shows that the hawthorns from the fieldstreated by the new techniques are either free of pesticide residual or with a residual 500～1000 times less than the residual standard fixed by FAO/WHO or the state.
