摘　　要：利用有机玻璃管土柱模拟田间试验的方法,研究了在滨海粉砂淤泥质土壤中加入不同厚度的半腐熟玉米秸秆肥、稻壳和河沙对提高土壤渗透性的效果。结果表明:施入河沙后的水分入渗速度和单位时间渗水量与对照差异不显著;施入稻壳后,虽然水分入渗速度和单位时间渗水量与对照相比显著提高,但远不及施入半腐熟玉米秸秆肥的效果好。改善滨海粉砂淤泥质土壤渗透效果的适宜技术为铺5 cm半腐熟玉米秸秆肥,混入0～40 cm土层。Using the method of the organic glass tube soil column simulated field experiment, the effects of adding different proportion of half-composting corn stalks fertilizer, rice husks and river sand on improving the soil permeability in coastal silty muddy soil were researched. The results showed that the water infiltration rate and water leakage amount per unit time after applied the river sand were not significant with the control. The water infiltration rate and water leakage amount per unit time after applied the rice husks were significantly higher than the control, but far less than applied half-composting corn stalks fertilizer in soil. The appropriate technology to improve soil permeability effect in coastal silty muddy soil was laying half-composting corn stalks fertilizer with 5 era, and mixed with 0 -40 cm soil layer.
