摘要
对麦田中芦苇的空间分布型及抽样技术进行了调查,结果表明,芦苇的空间分布为聚集分布,分布的基本成分是个体群,且聚集强度随着杂草密度的增加而增强。
Spatial distribution and sampling techniques of Phragmites communis in wheat fields were studied. This weed has an aggregated spatial distribution with individual distribution group as basic components. Aggregation intensity increa- ses with the increase of weed density.
