摘要
对毛竹叶螨发生的竹林进行劈草和锄草抚育,通过1a观察发现,锄草的竹林中的毛竹叶螨的种群密度和危害高于劈草的竹林。建议竹林抚育要因地制宜,对杂灌不繁茂、土壤较疏松的竹林不劈草。对杂灌繁茂的竹林于8-9月份劈草,尽量不锄草。释放捕食螨防治毛竹叶螨结果表明,捕食螨防治效果留草竹林大于劈草竹林、大于锄草竹林,所以毛竹叶螨的防治要与竹林抚育管理相结合,竹林在释放捕食螨防治毛竹叶螨的当年林下要留草,禁止全垦全劈。
Brush cutting and weeding were taken respectively in different bamboo groves which were harmed by leaf mites.After one-year study,the results showed that the damages and population density of leaf mites in weeded bamboo grove was higher than that in brush-cut bamboo grove.It was suggested that tending should hinge on local conditions.Bamboo grove should not be weeded,where brush was not luxuriant and the soil was porous.Brush cutting should be taken on August to September in bamboo grove where brush was luxuriant,but no weed.Study of letting off predatory mites to control harmful leaf mites showed that the control effect in bamboo grove with weeds was better than that in bamboo grove where weeds was eliminated or brush was cut.So complete reclaim and brush cutting should be prohibited in bamboo grove when predatory mites were used to control harmful leaf mites.
