【摘要】 采用覆盖技术可以提高玉米水分的利用率2.7%~89.0%,降低耗水量2.5%~12.7%和耗水强度2.5%~35.0%,水分利用趋于合理。采用地膜/秸秆二元覆盖和W地膜覆盖新技术节水效益较传统地膜覆盖提高3.2%~8.7%和0~9.5%,应作进一步深入研究。更多还原

【Abstract】 The mulching technique can increase 2.7%~89.0% of water utilization rate;decrease 2.5%~12.7% of water consumption and 2.5%~35.0% of water consumption strength in maize production.The saving-water effects of the double mulching with plastic film and straw,and W plastic film techniques increase by 3.2%~8.7% and 0%~9.5% compared with the traditional plastic film mulching technique respectively.更多还原
