孝义市麦田杂草现状及防治措施
|
摘要
4种阔叶优势杂草对小麦产量影响机理不同,在相同密度下,对小麦产量影响存在差异,在杂草种群的层次上,随着杂草种群密度增加,小麦减产量成倍增加。近年来,随着气候、耕作条件等条件改变,农田杂草构成发生了一定改变。
The effect mechanism of four dominant broad-leaf weeds on wheat yield was different, and the effect on wheat yield was different under the same density. At the level of weed population, with the increase of weed population density,wheat yield decreased exponentially. In recent years, with the change of climate, farming conditions and other conditions,the composition of farmland weeds has changed.
