| 摘 要： | 笔者以黄花梨为试材,研究了叶龄及树冠不同部位光强对其光合速率的影响。结果表明:黄花梨叶片在展叶后约11天即有少量光合产物输出,25天时,单叶净光合速率接近最大值;密植梨树高光合叶幕厚度约125cm左右。

| Abstract: | The authors used Huanghua pear as a test material and studied the effects of leaf age and different positions on canopies on rate of photosynthesis. It was shown by the results that the leaves of Huanghua pear exported a few photosynthetic substances on 11th day after spreading leaves, the net rate of photosynthesis of single leaf approximated to maximum on 25th day, and the thickness of high photosynthetic leaf canopy was about 125 cm in dense planting pear trees. |
