中文摘要：

通过冬小麦田间试验,研究了免耕、深松、翻耕三种不同耕作措施对土壤物理特性的影响。结果表明：冬小麦收获时,免耕与其它处理相比,增大了土壤容重、土壤硬度,其土壤干筛法〉0.25 mm团聚体含量比深松和翻耕每层平均增加3%和5%,但较冬小麦耕作处理前每层平均下降5%;免耕条件下,湿筛法〉0.25 mm团聚体含量比深松和翻耕每层平均增加11%和32%,较冬小麦耕作处理前每层平均下降42%;免耕可增加土壤蓄水量,收获期土壤蓄水量为373.1 mm,较深松和翻耕提高17%和8%;随着降水量的增加,冬小麦收获期水分入渗速率逐渐减少;且不同耕作方式水分入渗速率为免耕〉深松〉翻耕。

英文摘要：

Experiment was conducted to study the effect of different tillage measures on soil physical porperties of winter wheat field. The results showed that, in no-tillage treatment, soil bulk density and soil hardness, increased; soil macro-aggregates dry sieving content increased by 3 % and 5 % over sub-soiling and deep plowing, but decreased by 5 % compared with winter wheat soil preparatio; soil macro-aggregates wet sieving content increased by 11% and 32% over sub-soiling and deep flowing, but decreased by 42 % compared with winter wheat soil preparation. At the harvest time, no-tillage could inhibit soil water evaporation, and soil water storage capacity was 373.1 mm, increasing by 17% and 8 % over sub-soiling and deep plowing;with the increase of precipitation, the rate of water infiltration gradually reduced, and water infiltration rate of different tillage methods was in the order of no-tillage 〉 sub-soiling 〉 deep plowing.
