The Weed Investigation and Chemical Control Technology Research in Oil Flax Field of the Northwestern Hebei
摘要
Abstract
The weed types、communities and dominant weed species in oil flax field of the northwest-ern Hebei in the seedling stage were studied systematically,and chemical weed control test was carried out.The results showed that the weed types of local area in the seedling period of flax classified as 43 species weed of 16 families,and the dominant families were Gramineae、Compositae、Chenopodiaceae、Po-lygonaceae and Amaranth which accounted for 55.3% of all types.The dominant weed species were 11 , such as Chenopodium album L.,agopyrum tataricum(L.)Gaerth,Setaria viridis (L)Beauv.and et,al. The weed was 2 ~12 yuan community,and 6 ~9 yuan community was more than the others among them. Three kinds of controlling broadleaf weed herbicides were selected which control effects were above 85%,and the one of them was 40% 2 methyl octanoyl deltamethrin EC;Seven kinds of controlling gramineae herbicides were selected which control effects were above 90%,and the one of them was 10.8% Haloxy-fop -r -methyl.All herbicides screened were safe for oil flax and were suitable for popularizing and ap-plying in large area.关键词
