The Impact of Nurturing Thinning on the Growth of Artificial Cryptomeria Stands
In order to investigate the effect of different thinning intensities on the growth of artificial Cryptomeria stands,nurturing thinning was carried out on the artificial Cryptomeria stands(using post cutting canopy closure to reflect thinning intensity),with post cutting canopy closure of 0.50,0.60,0.70,0.85(control,no thinning).After 3a,the changes in the growth of artificial Cryptome-ria stands under different post cutting canopy closure were studied.The results showed that thinning and nurturing can effectively pro-mote forest growth,manifested in five aspects:average diameter at breast height,average height,cross-sectional area,average volume per plant,and forest volume.The study also found that among thinning and nurturing measures,the best growth effect was achieved when the post cutting canopy closure was between 0.5 and 0.6,with the highest volume growth observed at 0.5 canopy closure,signif-icantly higher than the other treatments.
