阿克陶县盐碱地开发项目治理措施效果

Effect of Treatment Measure for Saline-alkali Land Development Project in Akto County

为保障阿克陶县搬迁牧民的生活,采用平整土地、修筑灌排水系统等治理措施将未利用的盐碱地逐步开发成为耕地,对项目区原始地貌、工程完工后及第1次灌水洗盐后的土样进行采集,并测定土壤全盐的含量,作为实施效果的分析。结果表明,治理措施实施后,0~60 cm土壤层含盐量可减少58.4%,但第1次灌水洗盐效果不明显,后期需要水利、农业等多种措施的有效配合,才能逐步达到理想的种植要求,本研究为盐碱地的开发治理提供了借鉴。

In order to guarantee the living of the herdsmen in Akto County,the unutilized saline-alkali land was developed into cultivated land by measures such as leveling the land and constructing irrigation and drainage systems.The soil samples of the original landform of the project area,the completion of the project and after the first irrigation and salt washing were collected,and the total salt content of the soil was measured to analyze the treatment effect.The results showed that after the implementation of the treatment measures,the salt content of 0-60 cm soil layer reduced by 58.4%,but the effect of the first irrigation and salt washing was not obvious.It′s necessary to effectively cooperate with various measures such as water conservancy and agriculture to meet the ideal planting requirements.This study provided reference for the development of the saline-alkali land.
