樟树是我国南方的一种贵重用材和芳香油树种。1964年我所进行了大面积同一立地条件下不同密度(4×4、6×6、8×8、10×10、12×12尺)的植苗造林实验。经过了2年的观察,发现以4×4尺的生长最好,树木主干明显,生势旺盛;相反造林密度越小,生长越差,主干不明显,弯弯曲曲,生势也差(见表)。为了保证樟树造林后的成林成材,我们认为应采 Camphor tree is a valuable timber and aromatic oil tree species in southern China. In 1964 I carried out a large area under the same site conditions of different density (4 × 4,6 × 6,8 × 8,10 × 10,12 × 12 feet) of plantation afforestation experiment. After 2 years of observation, it was found that 4 × 4 feet of the best growth, the tree trunk obvious, strong potential growth; the contrary, the smaller the density of afforestation, the worse the growth, the trunk is not obvious, twists and turns, the potential is also poor (see table). In order to ensure the success of camphor tree planting, we think it should be adopted
