【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％。更多还原

【Abstract】 This paper studies on the energy metabolism in the process of photo-synthesis, respiration and transpiration of the soybean （Glycing soja） see-dling 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.更多还原
