| 摘 要： | 研究了新疆春大豆高产（4500kg.hm^-2)条件下群体光合速率，呼吸速率的变化。结果表明，高产大豆群体光合速率在整个生育期的变化呈单峰曲线，在开花期以前稳定上升，至结荚期达到最大，为4.165gCO2.m^-2.h^-1，鼓粒末期开始下降，全生育期平均值为2.321gCO2.m^-2.h^-1。群体呼吸速率随生育时期的变化呈现单峰曲线，盛荚斯达到最大值，为1.962gCO2.m^-2.h^-1。群体呼吸速率日变化的趋势与光合速率相似，亦呈现单峰型曲线，至中午14：00－16：00达最大值，呼吸速率的日变化与温度成显著正相关。

| Abstract: | This paper is a study on canopy apparent photosynthesis(CAP)rate,canopy respiration of spring soybean in high yield of Xinjiang.The result showed that the CAP rate of soybean during the entire growth period generally varied according to a single curve,where the peak value was usually reached around the time of full pod.The CAP of high yield soybean (4 500 kg/hm\ 2)usually increased before full bill.The change of CAP at various times of day generally varied according to a single peaks.The change of respiration characters is the same as CAP rate. |
