| 摘 要： | 田间试验的昼夜定时观测发现，不同肥力水平对土壤－植物连续系统水势有明显影响。在一定土壤含水量（２００ｇ／ｋｇ左右）下，随着土壤肥力提高，土壤水势有明显降低的趋势；小麦叶片细胞渗透势降低，小麦叶水势和叶片细胞的持水都有所提高。随着气温的升高，土壤－植物体系水势梯度（ψｓ－ｐ）呈增大趋势。

| Abstract: | Through continuous observation in field experiments, it was discovered
that,with certain soilwater content (200 g /kg or so), soilwater potential and Osmosis
potentials of wheat leaves decreased greatly, and water remained in leaf cells increased
somewhat with soil fertility increment, and the water potential gradient in soil-plant continuum had a tendency to increase with temperature rise. |

| Keywords: | soil fertility water and fertilizer effect water potential wateraccumulation by fertilizer application |
