%X <span style=\"font-size:14px;\">膜下滴灌是干旱区新疆农业节水灌溉主要模式，为农业节水增产水资源高效利用管理发挥了重要作用，本文在回顾总结微灌技术应用实践及取得成效的基础上，分析农业灌溉系统多要素投入对于产出综合效应，结果表明，化肥施用对农业产出贡献率38.7%，节水灌溉及水资源利用贡献率61.3%远大于农业施肥技术，但其中：膜下滴灌技术应用贡献率占比10.2%，低于灌溉水资源贡献率占比54.5%和渠道防渗及低压管灌贡献率占比35.3%。这一结果说明，农业灌溉投入产出系统尚处不和谐状态，间接反映了膜下滴灌引起灌水周期短、灌水频繁、用时长能耗高、定额小、土壤湿润层浅，地膜白色污染农田生态环境恶化，针对这些问题，本文提出了节水增效节能降耗环保型渗灌研究发展方向，为农业节水高质量发展提供支撑。</span><br />
<span style=\"font-size:14px;\">Underfilm drip irrigation is the main mode of agricultural water-saving irrigation in arid areas of Xinjiang, playing an important role in the efficient utilization and management of water resources for agricultural water-saving and yield increase. Based on a review and summary of the application practice and achievements of micro irrigation technology, this article analyzes the comprehensive effect of multiple factor inputs in agricultural irrigation systems on agricultural output. The results show that the contribution rate of fertilizer application to agricultural output is 38.7%, the contribution rate of water-saving irrigation and water resource utilization is 61.3%, which is much higher than that of agricultural fertilization technology. However, the contribution rate of the application of drip irrigation under film technology is 10.2%, which is lower than the contribution rate of irrigation water resources, which is 54.5%, and the contribution rate of channel anti-seepage and low-pressure pipe irrigation is 35.3%. This result indicates that the input-output system of agricultural irrigation is still in a disharmonious state, indirectly reflecting the short irrigation cycle, frequent irrigation, high energy consumption, small quota, shallow soil moisture layer, and deterioration of farmland ecological environment caused by white pollution of plastic film. In response to these problems, this article proposes the research and development direction of water-saving, efficiency increasing, energy saving, consumption reducing, and environmental protection infiltration irrigation, providing technical support for the high-quality development of agricultural water-saving.</span>
