【摘要】 为了解决地膜残膜污染问题,研究了易揭膜覆盖对旱地谷子生育时期和产量的影响。结果表明,易揭膜覆盖提高了土壤水分含量,加快了谷子的生长发育进程,可使谷子提早成熟,能促进根系发育,使根基部第1节间缩短,增强抗旱、抗倒性;易揭膜覆盖的产量比露地增产20.7%,比普通膜覆盖增产13.8%;收获后易揭膜的回收率可达到85%。更多还原

【Abstract】 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%.更多还原
