摘　　要：本研究旨在分析宁夏中卫市沙坡头区退砂地的土壤质量提升及农作物种植适宜性。通过连续3年的田间试验,收集并分析了8种宁夏地区广泛栽培的耐旱作物对土壤理化性质的影响及其经济效益。分析了退砂耕地适生农作物对当地土壤质量的影响及经济效益。结果表明,朝天椒和红葱在退砂地上表现出较高的产量和产值,且投入产出比大,是退砂地优先选择的作物。此外,玉米和小杂粮等作物轮作种植也显示出改良土壤结构和提高肥力的潜力。本研究为退砂地的科学利用提供了理论依据和实践指导,有助于推动中卫市经济社会可持续发展。This study aims to analyze the improvement of soil quality and the suitability of crop planting in the sandy land reclamation area of Shapotou District,Zhongwei City,Ningxia.Through continuous field experiments over three years,the effects of 8 drought-resistant crops widely cultivated in the Ningxia region on soil physical and chemical properties and their economic benefits were analyzed.The impact and economic benefits of suitable crops for sandy land reclamation on local soil quality were also studied.The results show that Cai Tian Jiao and Red Onion exhibit higher yields and output values on sandy land,with a large input-output ratio,making them the preferred crops for sandy land reclamation.In addition,the rotational planting of crops such as corn and mixed grains also demonstrates potential in improving soil structure and enhancing fertility.This research provides a theoretical basis and practical guidance for the scientific utilization of sandy land reclamation areas,contributing to the sustainable development of Zhongwei City's economy and society.
