OBJECTIVETo establish and optimize the cultivation systems for wild Huperzia serrata, through assessing the effects of environmental factors on its growth.

METHODH. serrata was planted under natural field condition, the growth status of H. serrata under different light intensities, temperatures, relative humidity (R. H.), fertilizer levels, and so on were investigated and analyzed.

RESULTH. serrata grew nicely under following environmental conditions: temperature ranging from 18.9-26.3 degrees C, R. H. ranging from 81%-90% and 1330-3000 lx light intensity. A cultivation system, in which H. serrata was planted in the bamboo forest and did not occupy the arable land, was established through the study.

CONCLUSIONConcluded that light intensity and R. H are the two factors which greatly confine the growth of H. serrata. As long as the levels of the above two factors meets the demands, H. serrata could be cultivated.
