为研究不同烘干温度和时间对测定土样潜在斥水性的影响,选用以色列2种类型的4种土壤,通过在25、45、65和105℃的4种不同温度和不同时间的组合对土壤样品进行烘干,然后测定潜在土壤斥水性,最后分析不同烘干温度在不同时间下对不同土壤潜在斥水性的影响。结果表明,在测定土壤潜在斥水性时的最佳烘干温度为45～65℃,最佳烘干时间为24h。 In order to study the effect of different drying temperature and time on the potential water-repellency of soil samples, four soil types were selected from two types of soil in Israel. Soil samples were collected at four different temperatures and different times at 25, 45, 65 and 105 ℃ The samples were dried and then the potential soil water repellency was determined. Finally, the effects of different drying temperatures on the potential water repellency of different soils at different times were analyzed. The results showed that the best drying temperature was 45 ~ 65 ℃ and the best drying time was 24h when soil potential water repellency was determined.
