Rhizospheric Soil Fertility under Compound Pattern of Cunninghamia lanceolata-Aleurites fordii-Mesora chinensis

Cai Liping, Chen Guangshui, Xie Jinsheng. Yang Yusheng(Department of Resource and Environment. Fujian Agricultural and Forestry University, Nanping 353001. P. R. China)  
A study on rhizospheric soil fertility under compound pattern of Cunninghamia lanceolata-Aleurites fordii-Mesora chinensis was carried out, and the results showed that the pH value was higher under compound pattern than under the control. The contents of organic matter and total N of rhizospheric soil wers both higher than those of soil under compound pattern. The difference in content of organic matter and total N between rhizospheric soil and total soil of Cunninghamia lanceolata was higher than that of soil under compound pattern. The rhizospheric soil has higher hydrolyzed N, and lower available P and available K than total soil both under compound pattern and the control. The rhizospheric soil of Aleurites fordii and Mesora chinensis had more figure in microbes and physiological groups. and higher biochemical activity than that of Cunninghamia lanceolata. and the amount of microbes and biochemical activity of total soil and rhizospheric soil under compound pattern were both higher than those under the control. It concluds that compound pattern can benefit the soil fertility. and hence stimulate the growth of Cunninghamia lanceolata.
