| 摘 要： | 采用随机调查的方法,对不同耕作制度下棉田杂草的种类和数量进行调查研究,从中发现,不同的耕作制度对杂草种类和数量的消长有很大的影响.免耕不覆秸秆、免耕覆秸秆、翻耕覆膜及翻耕不覆膜四种处理下,以免耕不覆秸秆条件下杂草的种类和数量最多,由此调查还可知道在免耕条件下覆盖秸秆也是控制棉田杂草滋生的一种有效措施.

| Abstract: | Based on the investigation of random block the weeds' kinds and their quantity were conducted in the cotton fields under different cultivation systems.In our study the dynamic of increasing and declining on weed species and number was affected significantly by the various tilling systems.Among four treatments of fallowing without straw mulching,fallowing with straw covering,plowing with film and ploughing without film the weeds species and number would show a maximal value in the system of fallowing without straw mulching.Meanwhile straw incorporated soil in the fallow fields would be favor for controlling and inhibiting weeds growth and their widespread,which will be one of feasible and efficient measurements accounting for weed eradication in the ecological and sustainable agriculture. |
