- 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.
