摘要
研究了玉米田覆盖渗水地膜后的增温调温、保墒提墒和增产效应,结果表明:渗水膜覆盖具有增温效应,对于夏季土壤的极端温度有一定的调节作用;生育期内土壤平均含水量为15.2%,与其他处理的差异达极显著水平;渗水膜覆盖增产幅度达25%~60%,与其他处理比较,差异均达极显著水平。
The experiment was designed to study the efficacy of water-osmosis plastic membrane in maize field, the result indicated that water-osmosis plastic membrane could increase and adjust the soil temperature. The average soil moisture was 15.2% during the whole maize growth period, and the yield was increased by 25%-60% compaired with other treatments.
