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.
