| 摘 要： | 通过对具有代表性样地的调查,初步了解了黄河中下游典型地区主要田间杂草的及分布特点.研究结果表明,调查样地出现的各种杂草种类共22科,55种,主要为禾本科(Gramineae)、菊科(Compositae)、十字花科(Cruciferae)、藜科(Chenopodiaceae)、石竹科(Caryophyllaceae)和莎草科(Cyperaceae)等;不同作物田块的杂草群落的分布存在显著差异;通过对相对多度的分析,开封郊区的杂草种类可主要分成两个聚类.

| Abstract: | In this paper, by the typical plots surveying, the main weed species and its distribution of different land use types in the middle-lower reach of the Yellow River were primarily studied. The results showed that, in different typical fields, all kinds of weeds belong to 22 families, 55 species mainly including Gramineae, Compositae, Cruciferae, Chenopodiacea, Caryophyllacea, Cyperaceae and so on. The distribution of weed clony in different fields has apparent differenciation. Relative abundance analysis indicates that all kinds of weeds mainly belong to two clusters in the surveying area. |
