摘　　要：为探索防治芦笋育苗田杂草的适宜除草剂类型及其对苗期芦笋的安全性,利用花盆种植芦笋,在温室内分别进行了7种封闭类除草剂和7种苗后除草剂对芦笋幼苗生长的安全性评价。结果表明:播后苗前施用330 g/L二甲戊灵乳油750 mL/hm2对芦笋出苗影响不明显,苗后施用15%精吡氟禾草灵乳油500 mL/hm2对芦笋幼苗生长无明显的药害症状,2种除草剂均可以在芦笋育苗田使用。To choose the best herbicides types for controlling weeds in asparagus seedling field and determine its safety evaluation for asparagus, experimental studied the influence on asparagus seedling of seven pre-emergence spraying herbicides and seven post-emergence herbicides.The results showed that 330 g/L pendimethalin EC （750 mL/hm2） had little influence on the emergence of asparagus, 15% fluazifop-P EC （500 mL/hm2） had no significant phytotoxicity on asparagus seedling.The two kinds of herbicides could be used in asparagus seedling fields, and other herbicides could cause different extents of phytotoxicity.
