摘　　要：用盆栽方法研究了夏大豆叶片蒸腾速率的时空分布及其与水肥条件的关系。结果表明,夏大豆叶片蒸腾速率日变化,蒸腾速率与叶龄、株龄、水肥条件的关系均呈单峰曲线,可用模式y=ax^pe^(bx)模拟。各生育时期植株干物质积累与蒸腾速率呈显著线性正相关关系.The time and space distribution of transpiration rate of leaves and its relation to conditions of water and fertilizer in summer soybean were studied with the method of pot culture in 1986～1988. The results showed that the diurnal changes of leaf transpiration and its relations to leaf age,plant age and conditions of water and couplex fertilizer were described with single peak curve and were simulated with model y=ax^pe^(bx).The positive linear correlation between accumulation of dry matter of plant and transpiration rate were significant in each growth stage.
