摘　　要：百合田杂草一直是影响百合产量和食用品质的一大障碍。为完善百合田杂草化除技术,筛选百合田适用除草剂,我们在调查研究百合田杂草发生特点的基础上,开展了百合苗前土壤封闭处理和苗后茎叶处理等化除技术研究,比较多种除草剂的防效和安全性。结果表明:百合田杂草草相复杂,商陆与百合竞争力最强,是本地百合田主要的恶性杂草。百合田土壤封闭处理适用的除草剂品种有精异丙甲草胺、乙草胺和二甲戊灵,其中乙草胺不能超量使用。苗后茎叶处理防除双子叶杂草适用的除草剂品种有草甘膦和二甲·灭草松,其中草甘膦一次用药即可达到防除禾本科和阔叶科杂草的目的,为确保安全性,制剂用量应控制在41%草甘膦异丙胺盐水剂200mL/667m2以下。Weeds in lily field have always been a major obstacle to the yield and edible quality of lily.In order to improve the chemical weeding technology and screen the appropriate herbicides for use in lily field,based on the investigation of the occurrence characteristics of weeds in lily field, the research was carried out on the pre -emergence soil treatment and post -emergence stems and leaves treatment to compare the control effect and safety of various herbicides.The results showed that the weeds in lily field were complicated,and,that Phytolacca acinosa Roxb was the most competitive to lilium and the main malignant weed in the local lily field.The herbicides suitable for soil treatment in the lily field were s -metolachlor,acetochlor and pendimethalin,among which acetochlor could not be used overdosed.The herbicides suitable for post -emergence treatment for the control of dicotyledons weeds were glyphosate and MCPA +bentazone,and one treatment of glyphosate was enough to eliminate and control grasses and broadleaf weeds effectively.In order to ensure safety,the application rate of glyphosate IPA 41% SL should be controlled under 200mL/667m^2.
