摘　　要：为有效降低小粒咖啡苗圃杂草防除成本,开展了3种药剂及不同处理方法防除咖啡苗圃杂草试验。结果表明,50%敌草胺可湿性粉剂施药后5 d再移栽咖啡沙床苗,不仅可以确保杀草效果,还能确保苗木不受伤害;30%苄嘧磺隆·丙草胺可湿性粉剂采用锯末作为混制“药土”材料,杂草防除效果不仅高于河沙“药土”,防除杂草效果最佳,且持效期长。Experiment of three pesticides against weed in coffee nursery was conducted to study the cost saving ways.It`s found that all three tested pesticides have effect on weed control to coffee seedling,of which 50%napropamide wettable powder has better control effect if treats before sprouting,the seedlings can be transplanted to field without any damage after spraying in 5 days.After sprouting,the 30%Bensulfuron-Pretilachlor wettable powder was thought to be the best one in controlling weed with long effective duration when used raw dust as medium soil.
