摘  要:
砒砂岩和沙是毛乌素沙地的两种主要物质,是造成当地水土流失和土地沙漠化问题的主要原因,在当地被称为"两害"。针对如何将砒砂岩与沙复配成土的技术问题,开展了砒砂岩和沙不同配比混合后的"复配土"特性研究,并在富平县及榆阳工程示范区进行了作物试种,均已取得良好成效。实验结果表明,玉米和马铃薯分别适宜在砒砂岩与沙为1∶2和1∶5的复配土中生长。对大田试种后的土壤肥力水平与环境质量状况的分析结果表明,各指标均符合种植标准。

摘  要:
Arsenic rock and sand,two main substances in Mu Us Desert,called "two evils" by the locals are the primary causes of soil erosion and land desertification.This paper mainly focuses on the farmland-building technology of mixing arsenic rock and sand.It also studies the characteristics of mixed soil of arsenic and sand in different proportions.The results showed that crops growing in Fuping County and Yuyang engineering demonstration zone had good effects,indicating that corn is suitable for planted in 1∶2remixed soil,and the most suitable ratio for potato is 1∶5.The soil fertility and environmental quality of mixed soil are both in line with the planting standards.
