新疆棉花膜下滴灌技术的应用与发展思考

Consideration on Application and Development of Drip Irrigation under Plastic Film for Cotton Cultivation in Xinjiang

新疆在棉花种植中将滴灌技术和覆膜植棉技术进行结合,覆膜减少水分蒸发而滴灌控制灌溉用水量,可有效减少深层渗透漏水。在对膜下滴灌技术的形成和发展进行分析的基础上,论述了此技术在新疆棉花中广泛运用与推广的原因,明确在膜下滴灌技术应用期间应注意的问题,并对新疆棉花膜下滴灌技术的应用与发展进行了分析。

Drip irrigation under plastic film was integrated for cotton planting in Xinjiang with decrement of water evaporation under soil covering with plastic film and with control of water amount of irrigation which could reduce water deep leakage effectively.Based on analysis of formation and development of drip irrigation under plastic film cover,the reasons of the widespread application and promotion were discussed,consideration of application of drip irrigation under plastic film in cotton cultivation was pro-posed,the development and further application of the technology in cotton production in Xijiang were analyzed.
