| Abstract: | Wheat is one of the most important crops in Shanxi. Recent years it has been seriously affected by the weeds. Inorder to control these weeds effectively with herbicides, the present paper has investigated the varieties, densities and distributions of the weeds in wheat fields of Jinzhong Basin. The results showed that there were 22 varieties of weeds in the wheat fields, 8 of which have caused serious damage to the crops. They were Chenopodium aibum L. ,Cephlanoplos segetum (Bge. )Kitam,polygonum avicu-lare L. , Descurainia sophhia (L. ) Schur, Silene conoidea L. , Chorispora tenella DC. , Convolvulus ar-vensis L. and Sonchus oleraceus L. . In addition, the field tests of control to the weeds with herbicides have also been conducted. |
