| Abstract: | This paper is a report of the preliminary study on nutrient circle (N,P,K,Ca,Mg)of the undergrowth in a mature Chinese-fir forest in Liluo,Longsheng county.The results indicated that the maximum quantity of accumulation,the annual remainder,total amount of annual nutrient return and the annual nutrient uptake were 179.6,142.1,25.3& 167.4 kg/ha respectively.In addition,disappearance and nutrient release of the dead leaves,concentrations,distributions and accumulations of the nutrients in the undergrowth plants were discussed and analysed in detail. |
