Analysis on Growth Effect of Different Afforestation Density of Cunninghamia Lanceolata
This paper studied the growth effect on the different planting density of Cunninghamia lanceolata with 8 years old.The result showed that there were significant differences in the DBH, tree height, crown breadth and volume growth on afforestation density of Cunninghamia lanceolata.The different afforestation density is as follows.The accumulation of Cunninghamia lanceolata with 8 years old is positively correlated with the size of its afforestation density.The higher the density, the earlier the differentiation of trees, which will affected its growth in late stage.Therefore, the reasonable planting density on the stand is particularly important to the normal growth and development.In this experiment, four different planting afforestation densities were analyzed to explored Cunninghamia lanceolata.The best result can be obtained when the density is 1600 plants/hm2.
