本文对西洋参地上植株类型做了多方面的调查和测定，植株高度四年生为２０．６～７０．５ｃｍ，三年生为２０．６～５０．５ｃｍ；植株花梗长度四年生为２～２４ｃｍ，三年生为５．５～１９．５ｃｍ；叶按长宽比划分为长型、中型、宽型。四年生有４７％植株为长型叶，有２７％植株为小型叶，２６％植株为宽型叶。三年生４１％植株为长型叶，３５％植株为中型叶，２４％植株为宽型叶。叶按叶展角度可划分为直立、平展，三年生有５２％植株属直立。四年生有１９％植株直立，２５％植株平展，其余性状不明显。果穗分紧穗型、散穗型，三年生、四年生均以紧穗为多，共比为５～７：１。果实结籽数有单籽果、双籽果、叁籽果，偶有四籽果、五籽果。植物类型多样，以宽叶、直立、紧穗为高产类型。 In this paper, we investigated and determined the types of plant on the ground of American ginseng. The plant height was 20.6-70.5cm for four years and 20.6-50.5cm for three years. The pedicel length was 4-24cm, Annual is 5.5 ~ 19.5cm; leaf by aspect ratio is divided into long, medium, wide. Four-year-olds have 47% of the plants with long leaves, 27% with small leaves and 26% with broad leaves. 41% of perennials are long leaves, 35% are middle leaves, and 24% are broad leaves. Leaves can be divided according to the leaf exhibition angle upright, flat, 52% of three-year-old plants are upright. Four-year-old 19% of the plants erect, 25% of the plants spread, the remaining traits are not obvious. Spike sub-panicle type, scattered type, three-year-old, four-year-old students are more closely to the spike, the total ratio of 5 to 7: 1. The number of fruit seeds have a single fruit, double fruit, three seed fruit, sometimes four seed fruit, five seed fruit. Diverse plant species to the broad leaves, erect, tight ears for high-yield type.
