摘要
本文根据土壤入渗试验的要求,研制了一套新的野外入渗试验装置:该套装置是将马利奥特容器和改进后的双套环结合起来,可自动供水,提高了入渗水量的测量程度和灵敏度;同时,采用r透射法测量土壤水分在时空上的变化。试验所得结果可根据水量平衡原理对各时段所测量的入渗水量及土壤水分剖面的精度进行检验,从而为野外土壤入渗试验研究的资料分析提供了可靠依据。
Based on the requirements of soil water penetration test, we have developed a set of field soil water penetration testing devices. This set of testing devices is to combine Maliaut containers with the improved double jackets, and can supply water automatically, thus improving measurements and sensitivity of amount of penetrating water, and at the same time, r-transmission method is adopted to determine the variations of soil water in time and space.The results from the tests can be inden rifled in accordance with the principle of soil water balance in the amount of penetrating water determined in each section and the accuracy of soil water in the profiles thereby to provide the reliable bases for the analysis of the field testing data of soil water penetration.
