深松技术可有效提高土壤蓄水保墒能力，其中0~100cm土壤含水量增加了3.2%~5.9%，土壤稳定入渗率增加了62.5%~224%，累计入渗量提高58%~264%，0~30cm植物易效水提高了5.2%~14.9%，而0~30cm土壤容重降低了2.8%~15.1%；深松时间的选择也是影响深松效果的重要因素，播前深松要好于苗期深松；行距变化对土壤蓄水保墒效果影响不明显。

the technology of deep loosening can effectively improve the ability of soil water storage to keep moisture. The 0~100 cm soil moisture content increased by 3.2%to 3.2%, and the soil stability infiltration rate is increased by 62.5%to 62.5%, the cumulative infiltration volume increased by 58%~264%, 0 to 30 cm plant absorbed water increased by 5.2%~14.9%, and the 0 to 30 cm soil bulk density decreased from 2.8%to 15.1%. Determining the time of loosening soil is also an important factor that affecting the effects of deep loosening. The best time loosen soil is before sowing that much better than seeding stage. But the impact on soil water storage and keeping moisture by changing row ledge is not obvious.
