Effect of Different Fertilizer Levels on Vegetative Growth of six-year Camellia oleifera Plantation
The effect of different fertilizer levels ( 0. 25kg/tree, 0. 50kg/tree, 0. 75kg/tree, 1. 00kg/tree, 1. 25kg/tree, unfertilized) on vegetative growth of Camellia oleifera plantation was studied by selecting 6-year Camelia oleifera plantation in Bama County of Guangxi Province and after 3-year ’ s consecutive investigations on tree height, ground diameter and tree crown. The results showed that different fertilizer levels did not demonstrate similar tendency on tree height, ground diameter and crown of young Camellia oleifera plantation. The effect of treatment CK was the smallest for vegetative growth performance, treatment with 1. 00kg/tree showed the best effect in increasing the height of Camellia oleifera, while treatment with 0. 50kg/tree showed the best effect in increasing ground diameter and crown of Camellia oleifera plantation. By considering fertilizer levels, economic cost and veg-etative growth, it was concluded that the fertilization level of 0. 50kg/tree treatment had the best effect in increas-ing the vegetative growth of young Camellia oleifera plantation.
