摘要
本试验研究9种化学除草剂对‘济粱1号'播后苗前和苗后田间杂草防效、产量等性状的影响,筛选出既能有效防除杂草又能保证‘济粱1号'正常生长的除草剂。即:苗前单一除草剂50%异甲·莠去津悬乳剂200 m L(666.7m2用量,下同)和33%二甲戊灵150 m L封闭喷雾,苗后5—6叶期喷施单一除草剂75%氯吡嘧磺隆8 g和复配除草剂(56%二甲四氯27 m L+50%二氯喹啉酸10 g+38%莠去津79 m L+75%氯吡嘧磺隆2 g)均可用于高粱杂交种‘济粱1号'的杂草防治。
In order to screen out the herbicides which had efficient weed control effects and could ensure the normal growth of Jiliang 1,the weed control effect and yield under 9 kinds of herbicide treatments were researched in the experiment before and after emergence.The results showed that before emergence,the 200 mL of 50%ISO-propylene compound atrazine and 150 mL of 33%pendimethalin per 666.7m 2 could be single used for closed spray,which were safe for the weed control of sorghum hybrid Jiliang 1.At the 5-6 leaf stage after emergence,8 g of 75%halosulfuron-methyl and compound herbicide(27 mL of 56%MCPA+10 g of 50%quinclorac+79 mL of 38%atrazine+2 g of 75%halosulfuron-methyl)per 666.7m 2 could be used for the weed control of Jiliang 1.
