A Study on Fertilizer Application to Nearly Mature Forest of Cunninghamia lanceolata

Cunninghamia lanceolata is the most important timber species with good quality in the south of China. It grows fast and is used widely. The Cunninghamia lanceolata stand aged 20 was tested on its density and fertilizer application. The growth in the following six years was summarized, which offers theoretical basis for culturing large-diameter timber of Cunninghamia lanceolate.
