| 摘 要： | 试验采用单因素随机区组设计,旨在研究禾耐斯与速收两种新型、高效除草剂对马铃薯田杂草的化学防除效果。结果表明:禾耐斯100 mL/667m2+速收12 g/667m2药后30 d对马铃薯田禾本科杂草和阔叶杂草的株防效均可达100%,且对马铃薯出苗无影响,该处理药后50 d对马铃薯田禾本科杂草和阔叶杂草的株防效及鲜重防效分别为97.47%、96.60%和99.08%、99.93%,且对马铃薯生长较安全,与对照相比,可使马铃薯增产18.62%;禾耐斯100mL/667m2药后30 d对马铃薯田禾本科杂草的株防效可达98.48%,药后50 d株防效为94.94%、鲜重防效为84.29%,与对照相比,该处理可使马铃薯增产5.08%;速收12 g/667m2药后30 d对马铃薯田阔叶杂草的株防效为99.77%,药后50 d株防效为96.31%、鲜重防效为98.74%,与对照相比该处理可使马铃薯增产8.53%。

| Abstract: | Single factor randomized block design was used in order to study chemical control effect of two new kinds of high efficiency herbicides Sumisoya and Harness on weeds in potatoes fields.The results showed that after 30 days,the control effect of combining Harness with 100 mL per acre and Sumisoya with 12gram per acre could amount to 100 percent,and which had no obvious bad influence on potatoes germination.After 50 days,the effects of this treat on grass weeds or broadleaf weeds were 97.47 percent and 96.60 percent in stem effect,and 99.08 percent and 99.93 percent fresh weight effect.And this treat was safety to the growth of the potatoes.It resulted in 18.62% increased production per acre comparing with contron;The stem control effect of Harness with 100 mL per acre on grass weeds could amount to 98.48 percent after 30 days and 94.94 percent after 50 days.The fresh weight effect of this treat on grass weeds was 84.29 percent after 50 days.This treat resulted in 5.08% increased production per acre;The stem control effect of Sumisoya with 12gram per acre on broadleaf weeds could amount to 99.77 percent after 30 days and 96.31 percent after 50 days.The fresh weight effect of this treat was 98.74 percent after 50 days.This treat resulted in 8.53% increased production per acre. |
