In areas where water resources are not sufficient, water resources are a major problem in limiting agricultural development. In order to use water resources rationally, many studies have found that no-tillage can increase the use of soil moisture and also stabilize the soil temperature.
Studies have shown that no-tillage increases soil infiltration rate and reduces surface runoff. When rainfall is 5 to 25mm, no-tillage soil has less disturbance, and the average infiltration rate of no-tillage treatment is faster than that of ploughing and can increase soil profile moisture content. Conservation tillage can significantly increase soil water storage and moisture content in soil layers from 0 to 200 cm. No-tillage is 1.80 times greater than that of conventional tillage. At 30 to 45 mm, it is 1.71 times faster than tillage. In addition, no-tillage also increased by 1.93% to 7.25%. This effect was more pronounced in less rainfall years. While straw cover inhibited evaporation, soil evaporation decreased by an average of 56.5% compared with no cover during the entire growth period. At the same time, no-tillage coverage is 1.3, which increases the transpiration efficiency of soil moisture and has an effective water retention effect of “into more and lessâ€.
At the same time, the analysis by soil moisture temperature detector showed that no-tillage also reduced the range of soil temperature changes. No-tillage soil showed a cooling effect during the winter wheat activity period, and a warming effect during the wintering period. Huang Gaobao et al. pointed out that with the traditional farming In comparison, no-till straw stalks can stabilize soil temperature, warm up slowly during the day, and cool more slowly during the afternoon to night. This is mainly due to the fact that no-tillage and straw mulching have both reduced solar radiation and prevented the spread of ground heat, creating a dual role of cooling and warming. No-tillage soil temperature is in a relatively stable state, harmonizing soil moisture, soil nutrient migration and transformation.
