摘要:
应用L i-6400光合仪测定不郁闭内人参净光合速率和蒸腾速率;应用温度表测定林内与林外的温度。结果表明,在生长季节内,林内温度低于林外温度,林下人参生长发育较差,产量较低;林分郁闭度为0.7~0.8时,人参的净光合速率、株高、单根重、叶绿素含量等指标较高;而郁闭度过高或过低都会影响人参生长发育;随着人参年龄的增加,净光合速率有逐渐升高的趋势。通过人为调节林分郁闭度的方式来满足人参对温度和光照因子的需求,为林下人参生长发育提供最适宜的生态环境。
Abstract:
The net photosynthesis and transpiration rate of ginseng in different canpoy densities, the temperatures of interior and exterior stand were measured. The rusults indicated that the temperature in forest was lower and the growth of ginseng was slower than out of forest, the yields were also lower; with the increase of ginseng age, the rate of net photosynthesis became higher; when the canopy density of forest reached to about 0.7～0.8, the net photosynthesis, hight, root weight, transpiration,chlorophyll conten of ginseng were higher than others, indicating that both lower and higher canopy density would reduce the rate of net photosynthesis of ginseng, and that the canpoy density of stand could be adjusted to satisfy the temperature and lighting for ginseng, and to provide the optimum ecology enviorment for the growth of ginseng.
