| Abstract |
The purpose of this study was to study the difference in growth between planted Cerasus jamasakura and Quercus serrata in the eleven plots where had 15m square the group selection openings of Cryptome...ria japonica and Chamaecyparis obtusa, established by nonprofit organization from 2007 to2010 in Kuroki Town, Yame City, Fukuoka Prefecture. For post-planting management, it was decided that underbrush would be cut only around the planted trees in order to increase biodiversity and competition among different species. Tree height measurement and vegetation surveys were conducted from 2007 to 2018. As a result, it was confirmed that the planted Cerasus jamasakura could grow to 857~1,017 cm in 11 years through interspecific competition with the pioneer species. The average annual tree height growth was 64 cm. On the other hand, it was confirmed that the growth of Quercus serrata was significantly inhibited by the shade of the surrounding artificial forest of Cryptomeria japonica, Chamaecyparis obtusa and other plants in the study area. The height of the trees was only 276~417 cm in the 10th and 11th year at the upper site of the study area. It was concluded that the growth of Quercus serrata was unsuitable under these conditions.show more
