| 摘 要： | 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。 |
| 关 键 词： | 土壤潜在斥水性 烘干温度 烘干时间 |

| Abstract: | In order to get the effect of the drying temperature and time on potential soil water repellency,Water Drop Penetration Time(WDPT) was measured after drying the samples in four temperatures,namely 25 ℃,45 ℃,65 ℃ and 105 ℃,and different time in the oven for two clay and two sandy soils collect from Israel.The result shows that the optimal temperature is 45~65 ℃ and the time is 24 hours for measuring potential water repellency after analyzing the different WDPT among the treatment for each soils. |
| Keywords: | potential soil water repellency drying temperature drying time |
