摘要
[目的]筛选佳木斯地区肇东苜蓿无药害除草剂品种和使用方法。[方法]通过土壤处理除草剂小区试验研究6种除草剂处理对肇东苜蓿分枝期苗情和草情的影响。[结果]6种土壤处理除草剂对阔叶杂草均有抑制或杀灭作用，对禾本科杂草也有一定防效。对肇东苜蓿无药害的药剂处理有75％阔叶散悬浮剂播后苗前喷雾，药害较轻的有5％普施特水剂播后苗前喷雾。对肇东苜蓿干草产量影响较小的为5％普施特水剂播后菌前喷雾和75％阔叶散悬浮剂播后菌前喷雾。[结论]肇东苜蓿无药害除草剂品种和使用方法推荐5％普施特水剂播后苗前喷雾。
Abstract
Objective] The aim was to screen some soil-applied herbicides for Medicago sativa L.field in Jiamusi and their application method. [Method] We studied the effects of six soil-applied herbicides on seedlings and weeds at branching period of Medicago sativa L..[Result] The six soil-applied herbicides had inhibition or killing effect on broadleaf weeds , and also had certain control against Gramineous weeds .75%thifensulfuron-methyl suspension concentrate spraying after sowing and before seedling had no phytotoxicity to Medicago sativa L., and 5% ima-zethapyr water agent spraying after sowing and before seedling had light phytotoxicity .Both 75%thifensulfuron-methyl suspension concentrate and 5% imazethapyr water agent spraying after sowing and before seedling had small effect on the hay yield of Medicago sativa L..[ Conclusion] It is recommended that 75%thifensulfuron-methyl suspension concentrate spraying after sowing and before seedling is suitable for controlling weeds in Medicago sativa L.field.
