摘要: 通过田间试验对二甲戊灵与扑草净混用防除绿豆田杂草的防效及对4个品种绿豆生长的安全性进行了研究。结果表明:二甲戊灵与扑草净混用可以有效地防除绿豆田主要一年生杂草,对杂草的总防效可达85%以上;二甲戊灵与扑草净混用试验剂量内对冀绿七号、白绿八号、科绿一号和蒙清绿豆4个品种生长的安全性较好,对绿豆出苗数及绿豆初花期的株高、根系鲜重和地上部鲜重等指标没有显著影响,对绿豆收获时的株高、有效英数、英长、单英粒数、百粒重和产量指标也没有显著影响。二甲戊灵与扑草净混用可以用于绿豆田除草,适宜的施药剂量为二甲戊灵600g/hm^2与扑草净300g/hm^2混用。

Abstract: Field experiments were conducted to analyze the control eftect of pendimethalin mixed with prometryn on weeds and its safely tor the growth with 4 varieties of mung beans. The results showed that the combination of pendimethalin and prometlTn can eftectively control the main annual weeds in mung bean fields, and the total control eftect of weeds was more than 85%. The mixed use of pendimethalin and prometryn had no detrimental eftects on the growth of 4 varieties of mung beans (Jilv 7, Bailv 8, Kelv 1 and Mengqing). There were no significant eftects on the seedling numbers, plant height, root fresh weight, fresh weight of upper ground of early flowering period, the index plant height, pods per plant, pod length, grain number per pod, 100-grain weight or yield of harvest time of mung bean. The combination of pendimethalin and promemy-n can be used for mung bean field weed management. The appropriate dose was found to be pendimethalin 600 g/hm^2 and prometryn 300 g/hm^2.
