【目的】研究南方地区再生水灌溉对红壤入渗特征的影响。【方法】以红壤为研究对象开展土柱模拟灌溉试验,采用再生水(RW)、稀释2倍再生水(RW-2)、稀释4倍再生水(RW-4)、稀释6倍再生水(RW-6)进行干湿交替灌溉,以蒸馏水灌溉(CK)为对照组。利用便携式入渗计进行入渗率测定,采用压力膜仪法测定土壤水分特征曲线。 【结果】再生水灌溉后,土壤水力传导度(K)减小显著(P

【Objective】Soil hydraulic properties are affected by many physical and biological factors and this paper presents the results of a study on the change in hydraulic conductivity of red soil irrigated with reclaimed wastewater in subtropical region in southern China.【Method】The red soil was packed into columns, and each column was then irrigated with reclaimed wastewater (RW), and diluted reclaimed wastewater at 2∶1 ratio (RW-2), 4∶1 ratio (RW-4) and 6∶1 ratio (RW-6), respectively. The control was freshwater irrigation (CK). The infiltrati...
