Research on the Interplanting of Chinese Goldthread Within Chinese Fir and Chinese Cedar Stands.

The interplanting of Chinese goldthread(Coptis chinensis) within Chinese fir(Cunninghamia lanceolata) and Chinese cedar (Cryptomeria fortunei) stands is a common practice in hilly areas of southeastern China. (1) the complex interplanting ecosystem has a considerably higher utilization rate of light-energy and its productivity is higher than pure stands of all three species; (2) the forest-medicinal plant interplanting system provides better environmental conditions for the growth of Chinese goldthread and consequently results in its higher yield; (3) compared with traditional cultivation with artificial shading, the forestmedicinal plant interplanting system can save shading material by 52.5m~3 per ha, labor hours by 28.7%, and incroase net income by 62.4%, labor productivity by 30.3%. The interplanting techniques of Chinese fir (or Chinese cedar) and Chinese goldthread are also briefly discussed.
