掌握树木的生理机能和生态特性对于科学营林具有十分重要的意义。山东省林业厅于1981年下达了“泡桐生理生态的研究”课题。至1985年我们主要研究了泡桐对各项生态因子的适应幅度以及各因子对泡桐的影响;在泡桐的生理机能方面,主要研究了能量转换、需光强度、净光合速率、气孔开关和蒸腾强度等问题。现将所获资料整理如下。
Grasping the physiological functions and ecological characteristics of trees is of great significance to scientific management of forests. Shandong Provincial Forestry Department in 1981 issued a “Paulownia physiological and ecological research” issue. By 1985, we mainly studied the adaptability of Paulownia to various ecological factors and the influence of each factor on Paulownia. In the physiological function of Paulownia, we studied the energy conversion, light intensity requirement, net photosynthetic rate, stomatal switch and transpiration intensity And other issues. The information obtained is now organized as follows.
