Abstract:

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.
