| 摘 要： | 为探讨几种化学除草剂对大豆田主要杂草的除草效果及对其他豆科作物安全性,选用除草剂异恶草酮、咪草烟、恶草酮和氯嘧磺隆在4种豆科作物间作田进行播后苗前土壤处理.结果表明:4种除草剂的总杂草株防效和鲜重防效分别为84.2%和84.4%以上,均与对照达到极显著水平,除草效果优良.4种除草剂对藜、马齿苋、反枝苋的株防效最高可达到100%.异恶草酮对反枝苋株防效为45.2%.氯嘧磺隆对稗草的株防效仅为11.7%,但对多年生问剂防效达89.8%,其他3种除草剂对稗草防效均较高,对问剂防效较低.从对豆科作物安全性看,4种除草剂都可以用于大豆田除草,与实际应用情况相符;异恶草酮禁用于绿豆、黄芪和黑豆;恶草酮禁用于黄芪和黑豆;氯嘧磺隆禁用于黄芪;只有咪草烟对4种豆科作物安全.

| Abstract: | Clomazone,imazethapyr,oxadiazon and chlorimuron-ethyl were studied in four bean intercrops to research their phytocidal effect and safety.In the test,the soil was treated with these herbicides after sowing and before sprouting.The results showed that the total phytocidal effect of four herbicides on individual weeds and fresh weight were 84.2% and 84.4% respectively.The control effect of four herbicides attained 100% in weeds of Chenopodium album,Portulace oleracea and Amaranthus retroflexus except that clo... |
