摘　　要：[Objective] The aim of this study was to study the influence of plants on the soil moisture content under different fertilization.[Method] Using sainfoin,sweet clover,Astragalus adsurgens,alfalfa,ryegrass,little flower,white clover as experimental material,this study explored the effects of soil moisture on the improvement of soil quality.[Result] Results showed that the soil moisture content of different plants follows as：sainfoin 〉sweet clover 〉Astragalus adsurgens 〉alfalfa perennial ryegrass 〉small crown 〉white clover,and the average moisture content reached 24.13% which was 2.45% higher than that of control group.At planting white clover,sweet clover,under the condition of 7 kinds of crops,in the treatments without fertilizer and with organic fertilizer,soil moisture content of soil in 0-20 cm grew significantly.[Conclusion] The application of organic fertilizer and growing of plants would improve soil moisture in abandoned fields,enhance the ability of soil water supply,and improve soil fertility.[目的]探讨不同施肥下植物对土壤含水率的影响。[方法]以红豆草、草木樨、沙打旺、紫花苜蓿、黑麦草、小冠花、白三叶为试验材料,研究土壤水分对于研究土壤的改良状况的重要性不可少的。[结果]不同植物的土壤含水率由高到低分别为：红豆草〉草木樨〉沙打旺〉紫花苜蓿〉黑麦草〉小冠花〉白三叶,平均含水率为24.13%,比对照高2.45%。在种植白三叶、草木樨等7种作物的条件下,不施肥与施有机肥均能明显提高土壤0-20 cm土层的含水率。[结论]施入有机肥和种植作物能够改善弃土场土壤的水分状况,减少土壤水分的损失,提高土壤保水供水能力,从而改善弃土场的肥力程度。
