新疆棉花地下滴灌应用发展对策

Discussion on Application and Development of Subsurface Drip Irrigation for Cotton in Xinjiang Production and Construction Corps

新疆是我国最主要的商品棉生产基地。被认为最复杂、效率也最高的地下滴灌技术,这几年在新疆兵团棉花的应用上,虽取得了一定的效果,但也出现了一些问题,一直没有规模化扩大,反呈负增长态势。分析了所产生问题的种类和原因,根据近年来的研究应用实践,认为应总结经验,正确评价地下滴灌技术的优缺点,因地制宜,加强管理;积极开展试验研究工作,特别是积极研究应用棉花移栽地下滴灌技术,它可能是兵团棉花节水灌溉和地下滴灌的主要发展方向之一。

Xinjiang is a major commodity cotton production base of China.In the past few years,the application of subsurface drip irrigation technology,which is considered the most complicated technology with the highest efficiency,has achieved some success in Xinjiang.However,there also existed several problems.The application has not been expanded on large-scale,but shows anti-negative growth trend.The types and causes of problems are analyzed in this paper.According to recent studies and practice,it is suggested that the experience should be summarized,the advantages and disadvantages of subsurface drip irrigation technology should be correctly evaluated,the application should be suitable to local conditions,the management should be strengthened,the experimental research should be actively carried out,especially on the application of cotton transplanting subsurface drip irrigation technology,which may be one of the major development direction of subsurface drip irrigation and water-saving irrigation in Xinjiang production and construction corps.
