test of artificial soil

In this thesis, with eight events of artificial water-washing test on five different slope gradients, factors affecting soil potassium loss by erosion, such as slope gradient, rain intensity, vegetation coverage, and amount of rainfall are discussed.

本文通过在5个不同坡度径流小区进行的8次人工模拟冲刷试验，探讨了坡度、放水冲刷强度、植被和降雨量等因素对土壤钾素径流流失的影响。

Then the test of plants by using artificial soil technology is the most important task and we can not afford failing in the test.
