| 在甘肃会宁，以陇糜5号为指示品种，研究了渗水地膜覆盖(T1)、普通地膜覆盖(T2)、露地(T3)3种种植方式土壤水分、地温效应及对旱地糜子生长发育的影响。结果表明，渗水地膜的渗水作用使其比普通地膜能接纳更多的雨水（在出苗期、抽穗期和成熟期的20～40 cm及40～60 cm耕层，均是T1＞T2），微气孔蒸发作用使得其0～20 cm耕层水分含量略低于普通地膜（在出苗期、抽穗期和成熟期的0～20 cm耕层，均是T2＞T1）；与露地相比，渗水地膜和普通地膜覆盖都具有明显的增温和保温效果，且增产显著，增产幅度分别是46.79%和67.13%，但渗水地膜和普通地膜处理之间产量差异不显著。 |

| In Huining county, Gansu province, Longmi 5 was used as the indicator cultivar to study the effects of water-permeable plastic film mulching, common plastic film mulching and no mulching on soil moisture and temperature, growth and development of broomcornmillet. The result showed that water-permeable plastic film with moisture permeable function was more effective on the water retention than common plastic film. However, micropore evaporation of the water-permeable plastic film caused moisture content slightly lower than that of the common plastic film at 0～20 cm soil layer. Compared with open ground, water-permeable plastic film and common plastic film had obvious effects on heat insulation and temperature increasing, which significantly increased broomcorn millet yield by 46.79% and 67.13%, respectively. However, there was no significant difference in yield between plastic film mulching modes. |
