摘要
麦田杂草的危害是造成小麦减产降质的主要因素。通过对我国几个典型小麦高产区域的麦田杂草种类及群落构成进行实证调查研究,结果表明,不科学的耕作方式、除草剂使用不当及气象因素是造成麦田草害危害加重的主要原因。因此,今后应加强农业、生物、化学等方面的防治措施,建立立体监测防治网络体系,保持麦田生物群落多样性,从而提高小麦产量。
The weed damage in wheat field is still one of the main causes of wheat yield reduction.After investigating the weed species and community composition in wheat fields in several typical high-yield areas of China,it was found that cultivation methods,inappropriate use of herbicides and meteorological factors are the causes of wheat field weed damage.Through strengthening agriculture and biology.In order to improve wheat yield,we should establish a three-dimensional monitoring and control network system to maintain the diversity of wheat bio-community.
