我国是一个农业大国,农业灌溉用水量较多,但我国的水资源现状极其紧缺、人均占有量少,节水灌溉技术的推广应用已经成为缓解我国水资源紧缺矛盾的战略选择。而膜下滴灌技术作为一种重要的、先进的局部节水灌溉技术,发展日益迅速并且前景愈发广阔。本文通过介绍膜下滴灌技术的概念及其特点、发展现状,提出了膜下滴灌技术存在的问题,并针对问题分析了相应的未来发展趋势,提出了今后需要进一步研究和探索的方向。
China is a large agricultural nation, where agricultural irrigation water consumption is huge and unefficient. However, the water resources are deficient and the amount of per capita is much less than the average in the world. As a result, the development of water-saving irrigation in our country has become a strategic choice for alleviating contradictions. As one kind of important, advanced water saving irrigation technique, drip irrigation under film technology is in broad and rapid development. This article introduces the concept of drip irrigation under plastic film technology and its characteristics, analyzes its development status, raises the issue of drip irrigation under plastic film technology, puts forward the appropriate future development trends, and raises further study and explo- ration direction required in the future.
