中文摘要:
      以高羊茅和草地早熟禾为试验材料,于2015年3月至2016年9月在上海交通大学农业与生物学院探索5种生产上常用的芽前除草剂对杂草的控制和草种子生产的影响。结果表明:适用于高羊茅种子生产的除草剂为40%扑草净WP,其处理的高羊茅种子单产较高,为793.3 kg/hm2,与人工除草处理产量无显著差异,杂草的株防效为69%;适用于草地早熟禾种子生产的除草剂为480 g/L氟乐灵EC,其处理的草地早熟禾种子单产较高,为200.9 kg/hm2,与人工除草处理无显著差异,杂草的株防效为59%;不适合在两种草种子生产中使用的药剂为960 g/L精异丙甲草胺EC,它对两种草坪草的生长和种子产量均有显著抑制作用。
英文摘要:
      Using Festuca elata and Poa pratensis as experiment materials, a study was conducted in School of Agriculture and Biology, Shanghai Jiao Tong University from March 2015 to September 2016.Effects of 5 preemergence herbicides on weed control and seed production were investigated and evaluated. The result showed that prometryn 40% WP was suitable herbicide for seed production of F.elata, the seed yields (793.3 kg/hm2) were higher than that of control, and there was no significant difference in seed yield between weed control by hand and applying prometryn 40% WP. The effect of weed control with applying prometryn 40% WP was 69%. Trifluralin 480 g/L EC was suitable herbicide for seed production of P.pratensis, the seed yield of P.pratensis.(200.9 kg/hm2) was higher than that of control, and there was no significant difference in seed yield between weed control by hand and applying trifluralin 480 g/L EC. The effect of weed control with applying trifluralin 480 g/L EC was 59%. S-metolachlor 960 g/L EC significantly inhibited the growth and yield of F. elata and P.pratensis, which was unsuitable for seed production of the two lawn grasses.
