摘要
[目的]研究豆科植物在石质边坡生态复绿中的应用效果。[方法]在杭徽高速昌昱段石质边坡生态复绿中种植8种豆科植物,2年后测定、比较它们的成活率、地上和地下生物量及优势度。[结果]草本豆科植物中白三叶的成活率最高,为8.3%;灌木豆科植物中紫穗槐的成活率最高,为6.0%。草本豆科植物中白三叶的地上、地下生物量均最大,分别为2.7、1.4 g,多变小冠花次之,分别为2.3、1.1 g。灌木豆科植物中紫穗槐的地上、地下生物量均最大,分别为15.2、3.0 g;其次为金雀儿,分别为9.2、1.8 g。白三叶、紫穗槐、金雀儿的优势度较高。[结论]白三叶、多变小冠花、紫穗槐及金雀儿是浙江省石质边坡生态复绿的首选植物材料。
[ Objective ] The aim was to study the application effect of legumes on the ecological greening in the stone slope. [ Method ] 8 kinds of legumes were planted in the Chang-yu part of the Hang-hui autobahn stone slope greening. After 2 years, their survival rate, the biomass and dominance above-ground and underground were detected and compared. [ Result] The survival rate of white clover was the highest among herb legumes, being 8.3 % ; the survival rate of Amorpha fruticosa was the highest among shrub legumes, being 6. 0%. The aboveground and underground biomass of white clover were the biggest among herb legumes, being 2.7 and 1.4 g resp. , the second was Coronilla varia L, being 2.3 and 1.1 g resp. The aboveground and underground biomass of A. fruticosa were the biggest among shrub legumes, being 15.2 and 3.0 g resp, the second was Caragana sinica being 9.2 and 1.8 g resp. The dominance of white clover, C. varia L and A. frutieosa was higher. [ Conclusion] The white clover, C. varia L , A. fruticosa and C. siniea were the first selective plant materials in Zhejiang province on the ecological greening in the stone slope.
