摘要

以不同恢复年限的人工和天然小叶锦鸡儿为研究对象，采用样地调查和室内外实验相结合的方法对小叶锦鸡儿的更新方式进行了研究．结果表明，不同年限小叶锦鸡儿结种量和百粒重差异明显；小叶锦鸡儿土壤种子库丰度随时间降低很快；虽然沙埋有助于提高种子萌发率，但野外条件下小叶锦鸡儿幼苗很难存活；平茬处理后小叶锦鸡儿枝条长势良好；小叶锦鸡儿到达一定年限后可通过自然萌生进行更新．说明在自然条件下，小叶锦鸡儿难以实现种子更新；自然萌生和人工平茬是其主要且有效的更新方式．

Abstract

Caragana microphylla is one of the key species for vegetation restoration in Horqin sandy land. Using field investigation and indoor and outdoor experiments

the regeneration of C. microphylla with dif-ferent ages were studied. The results show that there were obvious differences in seed yield and lO0-seed weight among C. microphylla with different ages. Seed density in soil decreased quickly with time. Seed-lings could hardly survive under natural conditions

although sand burial increased the seed germination rate. The branches grew well after stumping treatment. C. microphylla could regenerate through sprouting after a few years. In summary

it is difficult to implement seed regeneration for C. rnicrophylla under natural con-ditions

and sprouting and artificial stumping are the effective regeneration patterns for C. microphylla in the study area.
