A field experiment of 40 cm subsoiling under no-tillage 2 years later was operated from 2005 to 2006. Based on the data of soil moisture and crop yield, the physical basis of subsoiling for water conservation and yield increasing was analyzed.

土壤免耕第3年的基础上深松40cm，2005~2006年连续两年通过田间试验观测深松对土壤水分的影响，分析深松保墒增产的机理。

Based on the data of continuous field plot experiments for five years in Luoyang, the influence of four different tillage practices, namely reduced tillage, no-tillage, subsoiling and conventional tillage on the soil moisture, water use efficiency and crop yields of winter wheat was studied.

采用连续5a的田间定位试验资料，研究了洛阳地区休闲期4种不同耕作方式对冬小麦农田土壤水分变化、水分利用效率及作物产量的影响。

Delineation result based on the improved ant clustering indicated that the study area could be partitioned into two irrigation management zones. Soil field capacity, saturation moisture content and permanent wilting point in Zone I were greater than those in Zone II, which indicated that soil in Zone I had stronger drought resistance than that in Zone II under the same climate conditions. Delineation of irrigation management zones could provide references and data support for site-specified irrigation management.

改进的蚁群聚类分区结果表明，研究区可划分成2个灌溉管理分区，I区土壤的田间持水率、饱和含水率和凋萎含水率均较II区大，表明在相同的气候条件下，I区的土壤耐旱能力较II区强，分区结果可以为精准灌溉的分区管理提供参考依据和数据支持。

The results showed that tillage had stronger compaction effect on Red soil. By analyzing retention properties, water content was higher in the same suction for Red soil. Field capacity and wilting coefficient were higher for Red soil than those for Lou soil, but effective moisture and saturated hydraulic conductivity were lower for Red soil. For Red soil, Lateral infiltration ability was stronger, infiltration rate was greater than one number degree for Lou soil and preferential flow occurred easily.

结果表明：耕作片红壤有较强的压实作用；从持水特征分析，同一吸力下红壤的含水量较高，田间持水量和凋萎系数也高于塿土，而有效水含量略低于塿土，饱和导水率却低于塿土1个数量级；从入渗特征分析，红壤的侧渗能力很强，入渗率比塿土高1个数量级，容易发生大孔隙流。
