Extra care must be taken to be sure that water does not cut through any of the ridges between contour furrows.
要格外细心以确保水流不会穿越等高沟间的田埂。

The distributing trend of soil moisture contour map in under soil is rising up from bottom to surface, which indicates that ground water level has no influence on soil moisture variation.
下部土壤含水率等值线分布由底部向上都呈递增趋势，表明本次试验土壤水分动态变化不受地下水位的影响。
