近年霍县沿山千亩果园,普遍受到山楂红蜘蛛危害,特别是7—8月盛发期,红蜘蛛猖獗,叶色退绿,严重影响当年果品产量和下年花芽分化。广大果农突击喷药防冶,但仍减产1—2成,经济收入减少15—25％。为扭转这种被动局面,1988年我们在阎家庄乡刘家庄果园,根据山楂红蜘蛛在树下土块缝隙越冬、早春爬行上树的特性,在23棵苹果树上进行了涂药膏堆药土粘杀灭虫的综合防治试验,把害虫消灭在上树为害之前,有效地控制了其生物群落,收到了投资少效益高的预期效果。
In recent years Huo County acres of orchards along the mountains, are generally hawthorn red spider harm, especially in the peak period of July-August, spider rampant, leaves color green, seriously affecting the yield of fruit and the next year flower bud differentiation. The majority of peasants assaulted and sprayed anti-metallurgical measures, but still reduced production by 1-2% and their economic income decreased by 15-25%. In order to reverse this passive situation, in 1988 we were in Yanjiazhuang Liujia Zhuang Orchard, according to hawthorn spider mite under the trees in the cracks in the soil overwintering, early spring crawling on the characteristics of the tree, in the 23 apple trees were smeared ointment The comprehensive pest control test killed the pests before they were harmed by the tree and effectively controlled their biomes and received the expected benefits of less effective and less costly investment.
