摘　　要：随着我国设施农业集约化的快速发展,设施土壤次生盐渍化日益严重,致使土壤养分失衡,从而导致设施农作物产量和品质下降的问题日益突显。介绍了填闲作物的选择及其对土壤氮素的淋洗和消减作用,以及残体还田对土壤功能的影响,并提出了今后填闲作物改良土壤盐渍化的研究与发展方向。With the rapid development of facility agriculture in China,the secondary salinization of greenhouse soil is becoming more and more serious, which leads to the imbalance of soil nutrients and the decline of yield and quality of greenhouse crops. The paper expounded the research progress of the select catch corp, leaching and elimination of soil nitrogen by catch crops, effects of regression straw on soil function, and put forward research and development direction of soil salinization improvement with catch crops in the future.
