摘要
为明确山西省晋中市春播谷田杂草发生情况,在晋中市春播谷子种植区选取具有代表性的4个县、乡镇,共12块样地,采用倒置“W”取样方法,对杂草发生情况进行调查与分析。结果表明:晋中市春播谷田杂草共有14科30属31种,其中禾本科杂草7种,占杂草总量22.58%,阔叶杂草24种,占杂草总量77.42%;一年生杂草23种,占74.19%,多年生杂草8种,占25.81%。优势杂草为稗草(Echinochloa crusgalli)、反枝苋(Amaranthus retroflexus)、藜(Chenopodium album)、狗尾草(Setaria viridis)4种。不同县、乡镇杂草种类和相对优势度存在一定差异。
The occurrence of weeds in spring sowing millet fields in Jinzhong City,Shanxi Province,was determined by surveying 12 sample plots from 4 representative counties and towns.There were 31 species of weeds belonging to 30 genera and 14 families in Jinzhong spring sowing millet fields,among them,7 Poaceae species accounted for 22.5823%and 24 species of broad-leaved weeds accounted for 77.42%,while 23 species of annual weeds accounted for 74.19%,and 8 species of perennial weeds accounted for 25.81%.Echinochloa crus-galli,Amaranthus retroflexus,Chenopodium album and Setaria viridis were the dominant weeds.There were some differences in weed species and relative dominance among different counties and towns.
