摘要
以田间试验为基础对棉花膜下滴灌的灌溉制度及其各因素的特点进行了分析研究。膜下滴灌技术采用局部灌水 ,田间地面蒸发量很小 ,另外 ,该技术为浅灌且可控性强 ,使灌水深度与棉花根系吸水深度相一致 ,避免深层渗漏 。
Based upon field experiments, the under mulch drip irrigation regime for cotton as well as the factors referring to this regime were researched. By the local wetting to soil and the strict controllability, the under mulch drip irrigation technique can result in little land evaporation and in water to infiltrate in soil to the depth, within which cotton roots just absorb the water. Therefore, water leakage from deep soil is avoided and the water utilization ratio in field is raised.
