免耕种麦在节省用工、保证农时、提高总产等方面收到显著效益,但免耕种麦又会引起杂草增多,出草数常数倍于耕翻田,对产量构成严重威胁。近几年来,关于免耕麦田除草已有不少试验报道,但其中对恶性杂草看麦娘的防除尚缺乏应变弹性,防效因受气候条件影响而不稳定。本文试图对免耕麦田的杂草(以看麦娘为代表)的发生特点进行归纳,对已发表的试验结果进行较系统的分析,并据此提出防除对策。 Tillage-free wheat has received significant benefits in terms of saving labor, ensuring farm time and increasing total output. However, no-tillage wheat will cause more weeds to grow. In recent years, there have been many reports on weeding in tillage-free wheat fields. However, there is a lack of strain resilience in the control of weeds and weeds, and the control effect is not stable due to climatic conditions. This paper attempts to summarize the occurrence characteristics of weeds in Triticum aestivum (represented by Anemarrhena asphodeloides), analyze the published test results systematically, and put forward the countermeasures for prevention and control.
