农田野燕麦综合治理关键技术的研究

 农田野燕麦综合治理的关键技术主要有：⑴化学防除配套技术，包括土壤处理与苗期施药两项技术。麦田以燕麦畏与野燕枯，禾草灵、骠马配套使用，并与防除双子叶杂草的除草剂结合使用；油菜、豆田等采用氟乐灵与稳杀得、禾草克、盖草能配套使用，充分发挥化学除草效果。⑵以深耕-浅耕-浅耕或深耕-浅耕相结合的耕作法，使耕层土壤中野燕麦种子60%-80%分布0-10cm的浅层，配合除草剂使用，便于集中防除，收到了最佳除草效果。⑶实行小麦（青稞）-油菜（豆类）-小麦（青稞）轮作，配合使用除草剂，控制野燕麦效果达95%以上。⑷在野燕麦严重危害地区，实行化学除草与合理的耕作，轮作、人工除草等综合治理技术。三年即可控制野燕麦危害，使粮食产量翻了一番。

A STUDY ON KEY TECHNIQUES OF INTEGRATED CONTROL OVER WILD OAT ON FARMLAND

The key techniques of integrated management of wild oat are as follows:1.Chemical control, including both preemergence and postemergence applications, could provide good results. In wheat fields.Trialliate has been used for soil treatment combined with Difenzoquat, Diclofopmethyl or Puma super for fofiar appfication and with broadleaf herbicides;in rape and soybean fields Trifluralin, Quizalotop-ethyl, Haloxyfop, were all very effective.2.By ploughing yearly in the menner of deep-shallow-shallow Plowing or the combination of deep and shallow plowing,60%-80% of the wild oat sueds distributed in 0-10cm soil layer could be killed with herbicides effectively.3.Proper rotation of wheat (high land barley)-rape (pea and bean)-wheat (high land barley), combined with the application of herbicides could get more than 95% of reduction for wild oat comtrol.4. In the severely damaged area by wild oats, using chemical weeding, integrated with proper cultivationn, rotation and hand weeding the wild oat damage could be reduced and grain output might be doubled after 3-year control.
