人参(Panax ginseng C·A·Meyer)属于阴性植物,所以遮荫栽培一直是人参生产中的一个重要环节。过去多数参区一直采用坡式全荫棚,由于这种荫棚造价高,费材料,并且在这种荫棚下栽培的人参产量低、质量差。所以近年来不少地区改为双透(或单透)拱形棚和双透(或单透)坡式棚,使人参的产量和质量都有明显的提高。关于这 Ginseng (Panax ginseng CA Meyer) is a negative plant, so shade cultivation has been an important link in the production of ginseng.

Therefore, in recent years, many areas have been converted to double-penetration (or single-pass) arched sheds and double-penetration (or single-pass) sloping sheds to significantly increase the yield and quality of ginseng.
