分析了松嫩平原类闭流苏打盐渍土区水土资源之特点及开发利用中存在的问题及其发展趋势。根据三年试验结果提出了适于该区开发治理的“旱作,水田灌溉、发展芦苇、泡沼养鱼及发展畜牧业”的综合治理模式。为类闭流盐渍土区域的水土资源开辟了一条开发与治理相结合的途径。提出了类闭流区防止盐渍化,沼泽化的“统一规划,分段调控”的水盐调控技术,并将栽植芦苇这一生物措施运用到了水盐调控中,经三年运行耕地表土脱盐率达67%,灌溉期地下水位控制在0.7m以下。
The characteristics of soil and water resources in Songnen Plain closed-flow soda saline soil area and the problems and development trends in development and utilization are analyzed. According to the results of three years, the comprehensive management mode of “dry farming, paddy field irrigation, development of reed, bubble marsh fish culture and development of animal husbandry” is put forward for the development and management of this area. For the kind of soil and water resources in the closed flow salinized soil area, it has opened up a combination of development and management. Proposed water and salt regulation and control technology of “unified planning and segmented regulation” to prevent salinization and swamping in the closed flow area, and applied the biological measures of planting reed to water and salt regulation. After three years of operation, Rate of 67%, groundwater level during irrigation control in 0.7m below.
