| 摘 要： | 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T1T2),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T2T1);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。

| Abstract: | 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 wa-ter-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 in-sulation and temperature increasing ,which significantly increased broomcorn millet yield by 46 .79% and 67 .13% ,re-spectively .However ,there was no significant difference in yield between plastic film mulching modes . |
