Effects of Combined Fertilization on the Growth of Young Camellia oleifera Saplings

In this paper,studies were made of effects of different amount of N、P、K fertilizer on the sapling growth and chlorophyll content of superior clones of Camellia oleifera by the randomized block design in the field experiment. The results showed that combined fertilization had effects on the height, crown width and shoot growth of Camellia oleifera saplings to different degree. However, the sapling growth and chlorophyll content of young Camellia Oleifera forest were very different under the condition of different ration of fertilizer and application. Among them,the effect of treatment 7 was significantly greater than that of the other treatments. The optimum ratio of N、P、K (N:P₂O₅:K₂O) was 10:5:2 in this test.
