水是农业的命脉，我国作为农业大国，其整个耕地面积的40％是需要通过灌溉来保证其正常生产。因此，合理开发和调配有限水资源，推广节水灌溉技术，是保持我国经济社会可持续发展的关键。膜下滴灌技术作为一种新型的灌溉方式，促进了农业生产的一系列改变，成为现代农业的一个转折契机。本研究把实际研究与实地调查相结合，以有着华北地区的典型气候条件的环渤海地带为实际研究地点，以天津市宝坻区某镇村民为主要调查对象，以统计法为主要方法，以节水灌溉增产效益的计算模型为基础，就半湿润缺水地区的辣椒种植需水特点展开研究讨论关于膜下滴灌技术推广的可行性，为膜下滴灌技术及农业节水灌溉技术的发展及推广提供合理的决策参考。“,”For agriculture,water is the lifeblood,agriculture can not exist without water.China is a large agricultural country,40%of the cultivated area can only function normally through irrigation.As a new irrigation way,drip irrigation under plastic film promotes a series of changes in agricultural production,becoming a turning point to modern agriculture.This study combines practical study with field survey,choosing the particular Bohai region with typical climates in North China as the research spot.The main objects of this stud-y are those villagers in a certain town of Baodi district,Tianjin city.The main study method is statistics.Based on the calculation model of water-saving irrigation ,This study discusses the feasibility of the extension of technology of drip irrigation under film with the assum-ing characteristic that pepper plants need water in semi-humid water-deficient area.This study aims to provide reasonable suggestions about developing and promoting the technology of drip irrigation under film and the technology of agricultural water-saving irrigation technology.
