【摘要】 在旱地果园行间种植禾萱草,研究其对土壤的理化性质和土壤含水量的影响。结果表明:滴灌条件下,果园种植禾萱草,可显著改善土壤理化性质,使土壤容重降低0.13g/cm3,总孔隙度为对照组的1.12倍,非毛管孔隙度为对照组的1.68倍,土壤水分下渗速率提高,抗蚀性增强,具有显著的节水效应。更多还原

【Abstract】 Planting Bromuis inermis in irrigated orchards could obviously improve physics characteristics of soil,decrease the volume weight of soil by 0.13g/cm~3,with the total soil porosity being 1.12 times and the soil non——capillary porosity being 1.68 times of that in control.The soil infiltration rate and the ability of erosion resistance were improved,thus significantly improving water——holding capacity of the soil.更多还原
