Soil Fertility in Agroforestry System of Chinese Fir and Villous Amomum in Subtropical China

摘要

A trial of interplanting and non-interplanting villous amomum(Amomum villosum Lour.)under the canopy of Chinese fir(Cunninghamia lanceolata Hook.)at age 22 was established in Sanming, Fujian of China, and a survey on soil fertility was carried out 10 years after its establishment. Compared with the Control(non-interplanting), the properties of soil humus in agroforestry system were amelioraed, with a Higher level of humification and resynthesis of organic detritus.
