摘　　要：将原生长在海滨沙滩上的珊瑚菜(GlehnialittoralisFr.SchmidtexMiq.)迁地移栽至下列6种不同配比的土壤基质上,即全沙(Ⅰ)、1 2沙+1 2腐殖土(Ⅱ)、1 2沙+1 2黄棕壤土(Ⅲ)、黄棕壤土(Ⅳ)、腐殖土(V)和1 3沙+1 3腐殖土+1 3黄棕壤土(Ⅵ)。在定期定株连续观察基础上,比较分析了生长在上述6种不同基质中的珊瑚菜的成活率、生长发育状况和花果数量,发现在Ⅵ类基质上的珊瑚菜移栽成活率最高;在Ⅱ类基质上的营养生长最好;在Ⅲ类基质上的结实率及种子的饱满程度最高;而Ⅳ类基质对珊瑚菜的生长发育最不利。根据珊瑚菜生长发育状况的10个生物学指标,对上述各类基质进行了综合评估,认为对珊瑚菜迁地移栽最为有利的土壤基质依次为Ⅲ>Ⅱ>Ⅰ>Ⅵ>Ⅴ>Ⅳ。The individuals of \%Glehnia littoralis \%Fr. Schmidt ex Miq. introduced from the sandy beach of Liandao Island at Lianyungang in Jiangsu Province were planted in 6 kinds of soil medium at Nanjing, such as sand (Ⅰ), 1/2 sand + 1/2 humus (Ⅱ), 1/2 sand + 1/2 yellow\|brown earth (Ⅲ), yellow\|brown earth (Ⅳ), humus (Ⅴ) and 1/3 sand + 1/3 humus + 1/3 yellow\|brown earth (Ⅵ). The survival rate, growth situation, blooming and fruiting of \%G. littoralis \%planted in the above\|mentioned 6 kinds of soil medium were observed and compared. The results indicated that the survival rate of these individuals was the highest in Ⅵ, the nutrition growth in Ⅱ was the best, in Ⅲ the fruiting rate and the seed quantity were the highest, and the growth and development in Ⅳ was the most unfavorable. According to 10 indexes of the growth and development, the advantage of the above\|mentioned different soil media were evaluated and ordered for planting this species, and the order is Ⅲ>Ⅱ>Ⅰ>Ⅵ>Ⅴ>Ⅳ.
