本文对青海高原农田野燕麦的发生特点,如出苗、生长发育、繁殖和传播、种籽抗逆性等进行了初步试验。为认识野燕麦的危害性和制定防除措施提供了依据。在化学除草方面,试验了十几种除草剂和不同的应用条件,初步认为“深埋药”、“狠抓水”、“防耗损”、“促生长”是保证药效的重要环节。对旱地除草剂的应用有一定参考意义。 In this paper, the occurrence characteristics of wild oat in farmland of Qinghai Plateau were studied, such as emergence, growth, propagation and propagation, seed resistance and so on. In order to understand the dangers of wild oats and to develop measures to provide the basis for prevention and control. In the field of chemical weed control, a dozen herbicides and different application conditions were tested. It is initially believed that “deep-buried drugs”, “paying close attention to water”, “preventing loss” and “promoting growth” are important links to ensure efficacy. The application of herbicide in dry land has certain reference value.
