Abstract
The fertilization of mixed forests of Castanopsis fissa and Pinus massoniana for 2 years was tested.The results showed that the plant height of C.fissa grew fastest which average plant height was 183.6cm with the basic fertilizer treatment,and higher than that with the top fertilization treatment and without fertilization 10.1cm and 22.1cm,respectively.The increase of diameter at ground level of C.fissa was the fastest with the basic fertilizer treatment which average diameter at ground level was 2.41cm,and faster growth than that with the top fertilization treatment and without fertilization at 0.07cm and 0.27cm,respectively.The plant height of P.massoniana growed fastest which average plant height was 158cm with the basic fertilizer treatment,and higher than that with the top fertilization treatment and without fertilization 7.6cm and 15.2cm,respectively.The increase of diameter at ground level of P.massoniana was the fastest with the basic fertilizer treatment which average diameter at ground level was 2.19cm,and faster growth than that with the top fertilization treatment and without fertilization at 0.1cm and 0.23cm,respectively.
