Based on the previous study on cultivation nutrition of Cunninghamia lanceolata plantations of first generation, the cultivation nutrition of C. lanceolata plantations with multi-generation was studied. The results show that there are significant differences in the growth, development and nutrient assimilation among C. lanceolata plantations with different generations and nutrition conditions. These differences are closely related to the land fertility decline of C. lanceolata plantations. This paper demonstrates the mechanism of land fertility decline caused by successively planted C. lanceolata plantations, and provides the directions to work out proper nurture practices and management measures to keep land fertility from declining.
