摘 要: 通过对木生长规律的调查,表明木苗木属后期生长类型,全年有多次小的生长高峰,8月上旬有一次明显的、大的生长高峰。光合特性研究证明,木田间达到最高光合速率的时间为上午10∶30前后,其光合速率为18.0μmol/(m2·s),最适光合时期是7月下旬到8月下旬,最适光合温度为25~35℃。 Throngh research on Aralia chinensis, it is showed that its photosynthesis is of later period growth type, which has two fast growing stages, the mid ten days of June and the first ten days of August. It is also demonstrated that the time of the highest photosynthetic rate, with 18 0 μmol/m 2·s, is at 10∶30, the period of that is from the last ten days of July to the last ten days of August,and the suitable temperature of that is 25~35℃.
