摘 要：
本研究探讨了一种方便适用的土壤水取样方法及其配套技术。试验结果表明，采用自行研制的电动土壤水压榨取样仪进行土壤水压榨取样，样品的重复性良好。如果在土壤取样时共取30个点，则样品的代表性可以基本满足土壤水化学研究的试验要求。从田间采集的供土壤水化学研究使用的新鲜土壤样品，在用双层塑料袋密封的情况下，于4℃的冰箱中保存的时间不应超过3天。

摘 要：
An easy and fast method to obtain soil solution from original soil was developed method, and its related sample processes were studied in the paper. The newly developed. in which soil solution was pressured out from orlginal soil using the homemade squeezer, imposed good stability and reliability. Composite soil sample taken from 30 sampling points was shown to good enough to represent the soil for soil solution Study. The original soil sample for soil solution Study could not stored for more than 3 days at 4℃.
