| Abstract: | This paper examined two kinds of effective measures of how to keep and increase soil moisture.One of which was to research the effects of deeply loosing by plough to keep soil moisture based on the mechanisms and experiments.The other was to discuss the effects of irrigating which changed the soil moisture by changing the soil physical properties.These two measures were feasible and effective to keep and increase soil moisture in drought season. |
