Abstract
Through 10 years of building raw Schima superba Gardn.et Champ + Liriodendron chinense (Hemsl.) Sarg.mixed afforestation, Liriodendron chinense (Hemsl.) Sarg.pure forest growth effect were investigated, the results show∶ that under the condition of appropriate site, Liriodendron chinense (Hemsl.) Sarg.growth was significantly higher than Schima superba Gardn.et Champ, row of The same proportion of planting Liriodendron chinense (Hemsl.) Sarg.average diameter at breast height of 13.7 cm, the average tree as high as 9.2 m, volume of 81.823 m 3/hm 2, respectively, 47.3%, 12.2%, 131.4% higher than Schima superba Gardn.et Champ.Different mixing proportion of Schima superba Gardn.et Champ, Liriodendron chinense (Hemsl.) Sarg.growth has significant influence, in Liriodendron chinense (Hemsl.) Sarg.pure forest was the highest, Diameter growth, tree height growth, Total save numbers, the total volume of respectively,14.5cm,10.1m,2447strains/hm 2,204.325m 3/hm 2;Schima superba Gardn.et Champ,Liriodendron chinense (Hemsl.) Sarg.=1∶1 inter-row mixed growth of Secondly, Schima superba Gardn.et Champ,Liriodendron chinense (Hemsl.) Sarg.=3∶1 mingling between plant growth was the lowest.关键词
