| 摘要 | In this paper, the vegetable field in the teaching base of College of Agriculture, Yangtze University was taken as the research object. The indoor simulation method was used to explore the effects of temperature and moisture on the phosphorus (P) bioavailability of vegetable soil. Three temperature gradients [T1 (15℃), T2 (25℃), T3 (35℃)] and three humidity gradients [W1 (40%), W2 (70%), W3 (100%) were set in the test. The results showed that it could improve the contents of HCl-P, Enzyme-P, Citrate-P, and Olsen-P in vegetable soil by increasing soil moisture content; temperature rise was helpful to increase the contents of HCl-P and Olsen-P, but it could reduce the content of Citrate-P. The contents of Enzyme-P and CaCl2-P were significantly affected by hydrothermal interaction. Within a certain range of soil temperature and humidity, temperature and moisture had a positive coupling effect on soil P bioavailability components, and significantly affected soil P supply capacity. |
