Abstract：Using white insect-proof net，black insect-proof net and sun-shading net，we compared and studied the yield，quality，environmental factors of Gynura divaricata（L.）DC．The results showed that the quality and chlorophyll content were improved obviously，while the temperature and light intensity of greenhouse were reduced，the nitrate content was also decreased，the quality and growth of Gynura divaricata（L.）DC．were improved under sun-shading net cultivation．The comprehensive analysis shows that sun-shading net can be extended and applied in protected cultivation of Gynura divaricata（L.）DC．in summer at tropical areas.
