摘要
利用50%的乙草胺对玉米自交系及杂交种在播种后进行土壤封闭处理,以探讨乙草胺对春夏播自交系及杂交种的玉米田间杂草防除效果及药害表现情况,以便为玉米育种、制种单位和玉米大田生产提供参考。试验表明乙草胺对春夏播杂交种及自交系玉米田间杂草防除效果良好,但对春播自交系在低温多雨的天气条件下易产生药害而出现死苗现象。夏播自交系和春播杂交种也会产生轻微药害,夏播杂交种施用乙草胺比较安全。
In order to probe into the result and medicine suffer that second grass amine prevent and kill off maize field weeds of coeno-species, offer the reference for maize breeding, unit of reproducing seeds and maize business production, the soil that was produced maize inbred line and hybrids was sealed after seeding by utilizing 50% second grass amine. The test result showed that it was good to prevent and kill off maize field weed, but produce medicine hurt and appear shoot phenomenon extremely under the condition of low temperature and much rain, and produce same slight medicine suffer in summer sowing stage. It is relatively safer to use second amine preventing and killing off coeno-species weeds in summer sowing period.
