摘  要:
针对以物理方法消除斥水性的土壤进行污水灌溉后,土壤斥水性是否会很快重新出现的问题,采用自来水和3种不同生活污水为水源,对这种土壤进行滴灌,在灌溉了4个月和8个月后分别进行了斥水性差异显著性分析。结果表明,土壤斥水性会在灌溉一定时间后重新出现,并且与灌溉的时长和水质的优劣呈显著正相关。

摘  要:
The problemof whether the water repellency of the soil,in whichthe water-repellency soil is eli minated throughthe physical method,will reoccur or not shortly after irrigation with sewage,is discussedin this paper.The soil is irrigated through dripirrigation with tap water and other three kind s of domestic wastewater,and the significance difference analysis of water repellency is conducted after irrigation for 4 and 8 months.The result shows that soil water repellency will appear again after dripirrigationin a certainintervals.Meanwhile,it has a significant positive correlation withirrigation ti me and water quality.
