摘　　要：旱灾是制约辽西地区农业发展的重要因素。针对辽西干旱地区农业生产实际,介绍深松和坐水播种技术及其作用,并通过应用试验以验证其对土壤的保墒增墒效果。试验结果表明,在干旱条件下采用这两种技术可有效改善土壤情况,为种子发芽出苗创造适宜的环境条件。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.
