ABSTRACT
<p><b>OBJECTIVE</b>To investigate the photosynthetic characteristics of wildlife tending Alpinia oxyphylla, and provide a theoretical basis for choosing wildlife tending environment and cultivation management.</p><p><b>METHOD</b>The response parameters of the net photosynthetic rate to light intensity, CO2 concentration and photosynthetic characteristics were measured by Li-6400 portable photosynthesis in blossom bud forming stages under different treated conditions.</p><p><b>RESULT</b>The maximum net photosynthetic rate (Pmax), daily average photosynthetic rate (Pn), apparent quantum efficiency (AQY), apparent carboxylation efficiency (CE), light using efficiency (LUE), and water use efficiency (WUE) were optimal in the wild tending treatment at the light transmission rate of 17.4%-24.1%, beyond the light transmission rate, the photosynthetic capacity utilization of A. oxyphylla would not have a significant increase or be inhibited. The light compensation point (LCP) and light saturation point (LSP) of A. oxyphylla improved with light intensity enhancing. Wildlife tending could enhance the scope of A. oxyphylla to CO2 adaptation.</p><p><b>CONCLUSION</b>A. oxyphylla as sciophytes, and the optimum light transmission rate for wild tending and cultivating was at 17.4%-24.1%.</p>
