棉草灵系我所新研制成的棉花苗床复配除草剂,是一种内吸传导型的土壤封闭处理剂,兼有一定的芽后触杀作用.药剂主要通过杂草的幼芽吸收,茎叶和根系也可吸收部分药剂,从而破坏杂草正常的生理功能,最终导致杂草死亡.为明确棉草灵对棉花苗床期马唐、狗尾草、千金子、稗等一年生单子叶杂草和铁苋菜、地绵、鳢肠及藜科、苋科等一年生双子叶杂草的防除效果及安全性,1991～1992年进行了本研究,1993年在如东、大丰、兴化等地进行多点示范,现将主要研究结果总结如下:
Cotton seedling system is newly developed by our cotton seedbed compound herbicide, is a kind of internal absorption conduction type soil sealing agent, both with certain post-bud contact action.Pharmaceuticals are mainly absorbed through the sprouts of weeds, stems Leaf and roots can also absorb some of the agents, thus undermining the normal physiological function of weeds, and ultimately lead to the death of weeds.In order to clear cotton grass seedling stage Coturnum, Setaria, Trichosanthes, barnyardgrass and other annual monocotyledonous weeds and iron Amaranth, Radix Rehmanniae and Chenopodiaceae, Amarantha and other annual dicotyledonous weeds control effect and safety, from 1991 to 1992 conducted this study in 1993 in Rudong, Dafeng, Xinghua and other places to conduct more Demonstration, the main findings are summarized as follows:
