摘要
通过环境温度对西洋参生育期及产量品质的影响研究得出：西洋参植株生长最适宜温度为１４～１８℃，参根生长最适宜温度为１２．４～１３．２℃。秦岭山区，生长季平均温度在１７．５℃以上的地区有利于开花、结果，但参根生长欠佳，宜作西洋参种子生产基地；在１２．４～１６．０℃地区，气候冷凉，有利于参根生长，适宜作商品参基地。种植坡向，在低海拔地区宜种在北坡、东北、西北坡向，忌种植于南坡及川道；在高海拔地区，各坡向和川道均宜种植。
The effect of temperature on the growing period, the yield and quality of P.quinquefolium L. was studied. The results show that the optimum temperature is 14￣18℃ for plant growth and is 12 4￣13.2℃ for root growth of P. quinquefolium L. The Qinling mountain area where the mean temperature in growing season is over 17.5℃ is advantageous to blossom and fruit bearing, but is not good enough to root growth. It can be used as a base area for seed production. The area where the mean temperature is 12.4￣16.0℃ during the growing seasons is beneficial to root growth and the area can be used as a commodity ginseng base. In the area of low elevation, P. quinquefolium L. shoud be planted in the northeast and northwest slope. In the area of high elevation it may be planted in every slope and plain in Qinling mountain.
