疏勒河项目区盐碱地的形成及改良利用

疏勒河项目计划开发荒地523万hm2,由于其独特的地质、气候条件,该区土壤中普遍含盐,且中盐土和重盐土占绝大多数,主要的盐土类型有：沼泽盐土、草甸盐土、典型盐土和干旱盐土。针对不同的盐土类型,提出了相应的改良利用分区,盐土的改良,必须以“水、盐、肥”为中心,水利、农业、生物措施相结合,综合治理。

The formation and exploitation of the saline-alkali soils in the Shule River Project zone

The formation and exploitation of saline-alkali soil in the Shule River Project area were dissussed. Shule River Project was intended to exploit 5.23 hm2 cultivated farmland, but the soils contains high salt due to local climatic and geological conditions. The main saline soil types consist of marshy saline soil, meadow saline soil, typical saline soil & aridic saline soil. Therefore, the improvement of saline-alkali soil is very important at the present. The different exploited zones for the improvement of saline soil were proposed according to the saline soil types. The exploitation must focus on the "water, salt & fertilizer", and combine with irrigation, agriculture and biological measures for comprehensive harness.
