| 摘 要： | 为提高半干旱地区<10 mm降雨的有效性和改善地膜覆盖土壤环境的通气性，初步研究了微孔地膜覆盖效应.结果表明，微孔地膜覆盖处理具有纳雨补墒功能，可提高膜下土壤的含水量.随着塑膜覆盖度的增加，土壤中CO2浓度显著增高；孔膜覆盖处理的CO2浓度都较相应幅宽的普膜低，玉米植株根活力较高.根活力与土壤CO2浓度呈负相关.孔膜覆盖较普膜覆盖的玉米产量提高8.98%

| Abstract: | To improve the light rain availability and soil ventilation in semi-arid area, this paper studied the effectiveness of perforated plastie film mulehing on maize field. The results showed that perforated plastic film mulehing had the benefits of receiving rainfall and supplementing soil moisture. Soil CO2 content increased with increasing area of mulching, and was lower under perforated plastic film mulching than under common plastic film mulching. A negative correlation was observed between maize root vitality and soil CO2 content. The maize yield under perforated film mulching was 8.98% higher than that under eommon film mulehing. |

| Keywords: | Perforated plastic film Light rain availability Soil CO2 Root vitality. |
