旱地谷子易揭膜覆盖试验

摘要

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%.%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％.
