摘要: 结合模拟试验,对林下人参的生理活动及生长过程与林内生态因子的关系进行了观测研究.结果表明,林内光照、水分、温度等因子与林下人参生长的关系极为密切.一般林内光照在中等条件下,即相对光照在10~35%左右.林分郁闭度约0.6~0.8,土壤含水量在35~40%时人参生长最好;林下人参的物候进程及生长与温度的关系密切.林内温度在5℃左右人参芽胞开始萌动,15℃左右地上茎高生长进入速生期,6月上旬生长停止.因此,人为调节各种生态因子在适宜的范围内有利于林下人参的生长.

Abstract: With simulation experiment, the relationship between the phenology and growth of ginseng (Panax ginseng) under forest and some ecofactors, e. g., light. soil water and temperature was studied. Ginseng could grow best under conditions of 10~35% relative light intensity, 0.6~0.8 crown density and 30~45% soil water content. Its phenological process and growth were significantly affected by air temperature. It began to shoot when the air temperature was about 5℃, and its height growth became fast at about 15℃ in early May, and stopped at the beginning of June. It is advantageous for its growth through adjusting the niche conditions artificially.
