Can not only test the soil surface moisture, can also test of deep soil moisture, can meet the needs of the industry of scientific research, production, teaching and other related work demand.

不仅能够测试土壤表层水分，还能够测试深层土壤水分，能够满足上述行业的科研、生产、教学等相关工作需求。

They have also learned how to better preserved the precious surface water by using the thin film to cover the soil so that the evaporation of the moisture from the ground can be minimized.

他们也学会了用薄膜盖住土地，这样可以最大程度地防止水分的蒸发，以达到保持住弥足珍贵的地表水的目的。
