摘　　要：比较了土壤测试中传统操作模式和新的系列化操作模式的差异,指出提高测土配方施肥中土壤测试的效率是成功推广测土配方施肥技术的关键。传统操作模式使分析过程极为复杂烦琐,人为误差加大,大大限制了土壤分析速度,成为农民使用测土配方施肥技术的瓶颈。而现代化的系列操作模式通过采用联体杯、稀释加液器等系列化设备可以大大提高土壤分析的效率,减少人为误差。文章研究分析了稀释加液器的应用对提高土壤分析的效率和准确性的作用。The differences of traditional analysis model and modern system analysis model were compared in the paper. It was indicated that improving soil testing efficiency was the key for successful extension of soil testing and fertilizer recommendation technique. The traditional analysis model in soil testing was too complicated, too slow and with more testing errors. The slow service was probably the worst deterrent preventing farmer use of soil testing technique. The modern system analysis mode in soil testing with special measuring-cups, diluter-dispersers etc has high efficient soil testing and low analysis errors. The application of diluter-dispersers was studied in improving the efficiency and reducing error of soil testing.
