摘要
采用地膜覆盖植棉，可使棉黄萎病发生及发病高峰提早，病情加重，感病品种比抗病品种明显。但病指与对照差异不显著，且产量显著增加。
In cotton fields mulchd、with plastic membrane、the development of verticiliium wilt(Verticillium dahliae)and its peak shifed ahead in time and the symptoms were more severe. Sucheffects were more significant in susceptible ctltivars than in resistant cultuvars.Disease index,however.showed no great difference between the mulched fileds and the unmulched control.Mulching substantially enhanced the yield of cotton.
