soil water dynamic changes的意思|示意

Taking bare surface as CK, this paper discussed effect of straw-mulch during wheat stage on soil water dynamic changes and yield of summer maize.

以不覆盖的处理为对照，研究了冬小麦期覆盖秸秆对夏玉米土壤水分动态变化及产量的影响。

The model can predict not only the soil water dynamic profiles and the soil water potential profiles, but the changes of the effective root density with depth and time.

该模型除能预报根系吸水的一些水分动态和水势动态外，还能预报有效根密度的时空变化。
