小麦是晋中盆地种植的主要粮食作物之一,近年来受杂草为害较为严重.为化学防除提供理论依据,本文就晋中盆地麦田杂草种类,分布及演替等进行了调查分析.结果表明:晋中盆地麦田杂草共约有22种,大多为阔叶杂草,其中为害严重,分布较广的有8种,即:藜、刺儿茶、萹蓄、播娘蒿、麦瓶草、离子草、田施花、苦菜.并对各种杂草出现的频率,分布进行了分析比较,同时进行了化学防除比较试验.
Wheat is one of the main grain crops planted in the Jinzhong Basin and has been severely weed-harmed in recent years. In order to provide a theoretical basis for chemical control, we conducted a survey and analysis of the weed species, distribution and succession in the wheat fields in the Jinzhong Basin. The results showed that there were about 22 species of weeds in the wheat field in the Jinzhong Basin, mostly broad-leaved weeds, of which 8 species were severely damaged and widely distributed, namely: quinoa, burdock tea, Grass, ion grass, field flowers, bitter herbs.And the frequency and distribution of various weeds were analyzed and compared, at the same time, the chemical control comparative experiment was carried out.
