Easy Unmovable Mulching Film Experiment in Dryland Foxtail Millet

To solve the pollution of plastic film residue,effect of easy unmovable mulching film on growth stage and yield of dry land foxtail millet were studied.The results showed that: the easy unmovable mulching film could raise soil moisture content;and promoted the growth and development of foxtail millet and made it mature earlier;developed root system to drought,abbreviated internode to resist to lodging;the yield increased by 20.7% with the easy unmovable mulching film than that under open ground,by 13.8% than that under common plastic mulching;the recycling rate of easy unmovable plastic film after harvest could reach 85%.
