[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。
[Objective] The research aimed to discuss the effect of different fertilizers on soil water content. [Method] The research on the importance of soil moisture on the study of the improvement of soils was carried out using the materials of sainfoin, weeds, sand weeds, alfalfa, ryegrass, small crown flowers and white clovers. [Result] The highest and lowest soil water content of different plants were as follows: sativa> shrub> sativa> alfalfa> ryegrass> small crown flower> white clover, the average water content was 24.13%, higher than the control 2.45%. Under the conditions of planting white clover and herbaceous shrubs, soil moisture of 0-20 cm soil layer can be significantly increased by applying neither fertilizers nor organic manure. [Conclusion] Applying organic manure and planting crops can improve soil moisture status, reduce soil moisture loss, increase soil water supply and water supply capacity, and improve fertility of spoil grounds.
