摘要:
为了更全面地了解秸秆还田对土壤水分的影响，通过田间试验，分时期分土层研究了小麦和玉米两种秸秆在不同处理下还田对西北雨养农区冬小麦土壤水分的影响。结果表明：秸秆还田各处理土壤含水量的差异在时期上表现为前期大于后期，以越冬期的土壤墒情差异最大；在土层上表现为下层大于下层，以120—150 cm土层处理间差异最大。总体表现为：土壤含水量的差异随着生育时期的推进和土层加深而减小。同时，除小麦秸秆还田后不覆膜不镇压（T6）外其余秸秆还田处理的小麦产量和土壤水分利用效率均高于CK。其中，玉米秸秆还田后小麦产量和土壤水分利用效率均高于小麦秸秆还田；秸秆还田不覆膜，镇压（T2，T5）高于不镇压（T3，T6）。全生育期200 cm土体墒情秸秆还田好于露地（CK），秸秆还田覆膜（T1，T4）好于不覆膜（T2，T3，T5，T6）。无论是增产还是保墒，秸秆还田和地膜覆盖组合模式是最好的。
Abstract:
To comprehensively understand effects of straw returning on the soil water content, the effect of straw returning with wheat and maize under the different treatments on soil moisture of winter wheat in northwest rainfed agriculture was studied at different stages and soil layers in a field experiment conducted in Tongwei county, Gansu province. The results show that the differences in soil water content with straw returning in the early were larger than those in the late at different stages, the soil water content in winter period was the highest, the differences in soil water content in upper soil were greater than those in subsoil, which were the highest in 120—150 cm soil layer. In general, the difference was decreasing with the development of growth period and the soil layer depth. At the meantime, the yield and water use efficiency (WUE) of other treatments with straw returning were higher than those of control except for the treatment of wheat straw returning with no-express and no-film, in which the yield and WUE of treatment with maize straw returning were higher than with wheat straw returning, and straw returning with compaction and no-film were higher than with no-compaction and no-film. The soil water content of straw returning was higher than CK, that of straw returning with film was higher than with no-film. The combination of straw returning and film mulching was the best practice in terms of the rate of increasing yield and the soil water conversation.
