A pond soil culture experiment was conducted to explore the effects of different soil moisture content treatments (65% WHC, 75% WHC, 85% WHC, 95% WHC, and 100% WHC, where WHC represents the maximum field water capacity) on soil respiration rate and root number of upland rice 277. The results showed that the soil moisture remarkably affected soil respiration rate and root number. The soil respiration rate decreased significantly with the increase of soil moisture content. The soil respiration rate of 100%WHC treatment decreased gradually along with the development of growth stage, all other water treatments showed an upward trend. The root number gradually reduced with the increase of soil moisture, and the difference among the five water treatments reached to significant level in the early tillers, however, the difference among them is gradually decreased along with the passage of growth period. While extremely significant positive linear correlation was presented between soil respiration rate and root number. The daily variation of soil respiration rate showed a gradual increase and remained stable under 65% WHC, 75% WHC, and 85% WHC treatments, reached its maximum value and gradually decreased under 95% WHC treatment, and slightly decreased after reaching its maximum value, and remained at a relatively low level under 100% WHC treatment. The daily variation of soil temperature showed a trend of first increasing and then stabilizing under different soil moisture contents, with the highest temperature under 75% WHC treatment and lower temperature under 95% WHC and 100% WHC treatments. Correlation analysis showed that in all of the water treatments (except 100%WHC water treatment), significant or extremely significant quadratic parabola relationship were presented between soil respiration rate and soil temperature, while extremely significant positive linear correlation was presented between soil respiration rate and root number.
Key words： upland rice; soil moisture; root number; soil temperature; soil respiration rate
