Abstract: In order to improve the farmland soil structure, increase farmland’s productivity, soil moisture capacity and crop yield in Beijing, this project has been carried out since 2009 in conservation tillage farmland in Yanqing, Beijing, to study the effect of subsoiling. A thorough comparative analysis of no-tillage and notillage+subsoiling on soil bulk density, moisture rate, infiltration rate and crop growth and yield was conducted. The results of test indicated that compared with no-tillage, no-tillage+ subsoiling treatment could reduce soil bulk density by 3.4% and increase the stable infiltration rate by 62.5% within 0 to 30 cm soil layer, while the average soil moisture content was increased by 5.9% within 0 to 100 cm soil layer. Therefore the subsoiling could improve the soil water holding capacity, contribute to the growth of crops.
