Comparative Analysis on Growth of 2-Year-Old Cunninghamia lanceolata Cutting Clones and Mixed Forests of Castanopsis carlesii and Schima Superb
In order to track the growth of 2-year mixed forest with Cunninghamia lanceolata cutting clones with Castanopsis carlesii and Schima superba,the growth of pure forest,mixed forest with Castanopsis carlesii and mixed forest with Schima superba were measured in November 2023.The results show that the growth of height,diameter,height and diameter of 2-year-old Cunninghamia lanceolata clones in the mixed forest of Cunninghamia lanceolata and Schima superba were the best.The growth of height and diameter were 5.1%and 6.0%higher than the average of height and diameter of 2-year-old Cunninghamia lanceolata clones treated with 3 mixed forests,re-spectively;There was no significant difference in the distribution frequency of height and diameter of 2-year-old Cunninghamia lanceolata clones among the three mixed forests(P>0.05).
