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3 482.52~3 603.77 kg/hm2,增产效果显著,产量较空白对照增加36.17%~40.91%,每公顷增收2 127.5~2 406.4元。

Abstract: 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 3 482.52 to 3 603.77 kg/hm2 after treated with pinoxaden·mesosulfuron-methyl, which increased by 36.17%~40.91% compared to untreated control. Moreover, the yield income increased by 2 127.5~2 406.4 yuan/hm2.

Key words: pinoxaden·mesosulfuron-methyl, weed control effect, nutrient content, wheat yield
