摘要: 本文研究了大豆(Glying soja)苗期在光合、呼吸和蒸腾作用中的能量代谢, 结果表明, 大豆苗期的能量输入为990Kcal.m-2·h-1, 能量吸收为40.42Kcal.m-2·h-1, 能量固定为14.71Kcal.m-2·h-1, 能量损耗为28.61Kcal.m-2·h-1, 能量积累为11.71Kcal。m-2·h-1。由此可见, 绝大多数的能量损耗于大豆苗期的能量代谢过程, 其中, 蒸腾作用中的能量损耗为25.71Kcal.m-2·h-1, 光呼吸和暗呼吸作用中的能量损耗为3.00Kcal.m-2·h-1。因此,大豆苗期能量利用效率仅为1.18%。

Abstract: This paper studies on the energy metabolism in the process of photo-synthesis, respiration and transpiration of the soybean (Glycing soja) seedling stage. The results show that the energy input is 990 kcal·m-2. h-1, the energy absorbing is 40.42 kcal·m-2. h-1, the energy fixing is 14.71kcal·m-2.h-1, the energy dissipating is 28.61 kcal·m-2. h-1 and theenergy accumulating is 11.71 kcal·m-2.h-1, in the process of the energymetabolism of soybean (Glycing soja) seedling stage. That can be seen thatmost of the energy is lost in the energy metabolism, of which the tra-nspiration of the soybean dissipates 25.71 kcal·m-2.h-1 and the photo-respiration and respiration of the soybean dissipates only 3. 00 kcal·m-2.h-1. Thus, the efficiency of the energy utilization is 1.18% in its seedlingstage.
