松原灌区苏打盐碱地改良开发试验研究初探

Discussion on the experimental study of the soda saline-alkali soil improved development in Songyuan irrigation District

吉林省西部地区是世界三大苏打盐碱地之一,即将开发建设的松原灌区就在其中,灌区内分布着大面积的中重度苏打盐碱地。如何改良开发这些中重度苏打盐碱地,是开发建设松原灌区的关键,特别是重度盐碱地,改良利用上一直存在着见效缓慢、改良困难等问题。本次试验重点针对pH值9以上,ESP在40%以上的重度盐碱地,采取水利、农业、物理、生物、化学等技术的综合治理措施,力求摸索一套经济实效、易于推广的治理重度盐碱地的技术模式,以便于为松原灌区,乃至于吉林省西部盐碱地改良利用提供技术支撑。

The west area of Jilin Province is one of the world＇s three large soda saline-alkali soil,in which Songyuan Irrigation District will develop and construction is located.How to improve the development of these moderate to severe soda saline land,is the key of the development and construction of Songyuan district,es- pecially severe saline land,improvement and utilization has been issues of effective slow improvement.This test focused on pH above 9, the ESP more than 40% of the severe saline land, taking integrated governance mea- sures including water conservancy, agriculture, physics, biology, chemistry technology, which strive to explore a set of economic effectiveness, easy promotion model,in order to provide technical support for Songyuan irrigation areas,and even to the saline land improvement and utilization in the west of Jilin Province.
