| 摘 要： | 农作物地膜覆盖栽培技术是 2 0世纪 80年代发展起来的新技术 ,其保温、保墒和增产效果明显 ,但不同地膜覆盖率对减少土壤棵间蒸发影响规律 ,目前国内研究不多。通过在室内研究覆膜灌溉土壤蒸发规律 ,研究出不同土壤含水率的水分蒸发和不同覆盖率对土壤蒸发的影响关系 ,并在田间进行验证。为今后定量评价农作物地膜覆盖减少土壤棵间蒸发提供理论依据

| Abstract: | Crop cultivation with plastic film mulch is very popular in Northern China. The soil moisture and temperature situation may be improved obviously during crop growing season, and yield also may increase significantly under plastic film mulch cultivation. Laboratory experiments were carried out for investigating the effects of plastic film mulch on soil surface evaporation. The relationships between soil surface evaporation rate with soil moisture content and field cover rate with plastic film are analyzed with laboratory experimental data and are checked in outdoor field. |
