摘要
采用田间试验研究了6%唑啉草酯·甲基二磺隆可分散油悬浮剂防除小麦田主要杂草的效果,及杂草防除后对氮、磷、钾及水分的影响。结果表明,施用6%唑啉草酯·甲基二磺隆可分散油悬浮剂防除小麦田杂草效果显著,对牛繁缕(Malachium aquaticum)、棒头草(Polypogon fugax)、菵草(Beckmannia syzigachne)均有良好防效,总鲜重防效达90.8%~97.5%,优于2种对照药剂。杂草防除后,显著降低了杂草对田间氮、磷、钾和水分的消耗,有效改善了田间的水肥条件。6%唑啉草酯·甲基二磺隆可分散油悬浮剂处理的小麦田产量达3482.52~3603.77 kg/hm^(2),增产效果显著,产量较空白对照增加36.17%~40.91%,每公顷增收2127.5~2406.4元。
The effect of 6% pinoxaden·mesosulfuron-methyl OD on weed control in wheat field was studied.The wheat yield,the content of N-P-K and water were also analyzed after weed control by pinoxaden·mesosulfuron-methyl.The results indicated that the efficacy of weed control were remarkable by 6% pinoxaden·mesosulfuron-methyl WDG in wheat field.The control efficacy on Malachium aquaticum,Polypogon fugax and Beckmannia syzigachne was ranged from 90.8% to 97.5%.The accumulation of weed water and fertilizer was significantly decreased after weed control.The wheat yield was ranged 3482.52 to 3603.77 kg/hm^(2) after treated with pinoxaden·mesosulfuron-methyl,which increased by 36.17%~40.91% compared to untreated control.Moreover,the yield income increased by 2127.5~2406.4 yuan/hm^(2).
