[目的]研究绿豆田草害控制技术,并配套组装、开发与示范。[方法]通过田间试验,测定9种土壤处理除草剂对绿豆的安全性、除草效果及产量的影响。[结果]50%扑草净WP、25%氟磺胺草醚EC、75%噻吩磺隆WG在试验剂量下对绿豆的安全性好。70%嗪草酮WP 1 200 g/hm2、25%氟磺胺草醚EC2 250 m L/hm2对阔叶类杂草药效好。50%二氯喹啉酸WP 750、1 125、1 500 g/hm2处理对禾本科杂草药效较好。25%氟磺胺草醚EC 1 500 m L/hm2、48%异恶草松EC1 125、1 500 m L/hm2具有增产作用。[结论]48%异恶草松EC1 125、1 500 m L/hm2、25%氟磺胺草醚EC1 500 m L/hm2具有除草效果好和增产作用,可以作为绿豆田的主要除草剂进行示范推广。
[Objective] The research aimed to study the control technology of mung bean field and its supporting assembly, development and demonstration. [Method] The effects of 9 herbicides on mung bean safety, herbicidal effect and yield were determined by field experiments. [Result] The safety of 50% prometryne WP, 25% fomesafen EC and 75% thifensulfuron - methyl WG was better than that of mung bean under the test dose. 70% metribuzin WP 1 200 g / hm2, 25% fomesafen EC2 250 m L / hm2 Broad-leaved weeds with good efficacy. 50% quinclorac WP 750,1 125,1 500 g / hm2 treatment on grass weeds better. 25% Fomesafen EC 1 500 m L / hm2, 48% Clomazone EC1 125,1 500 m L / hm2 has the effect of increasing yield. [Conclusion] 48% EC1 125,1 500 m L / hm2 and 25% fomesafen EC1 500 m L / hm2 had good weeding effect and increased yield, which could be used as the main herbicide in mung bean field .
