This fact will be required a lot of raw material from a large scale factory, therefore, what kind of bamboo should be selected for a material. So, this study discussed on this matter through investigation and experiment. Results of this study are as follows: 1) Characteristics of bamboo different from trees and grass; 2) Environmental factors: a) annual mean temperature in 10-15 ℃ shows good growth of culm in temperate area and more than 20 ℃ also shows in tropical area, b) Rainfall: more than 1,000 mm year-1 is necessary for growth of culm in temperate and tropical area, and still more in addition to two times of 100 mm month-1 in temperate area, and three times of 200 mm month-l in tropical area, c) Soil and topography: brown colored soil and flat or gentle slope show better growth in temperate area, but red colored soil and slope are not suitable in tropical area, d) Geographical distribution of bamboo related with growth type shown in Figs. 1-3. Productivity of bamboo: annual productivity of bamboo is the biggest compared with other type of vegetation; 4) Selection of two growth type of bamboo: many big bamboos are growing in tropical area; 5) Furthermore items discussed in this report.展开更多
文摘The latest effective utilization of bamboo resources is changing from domestic industry to mechanical industry. This fact will be required a lot of raw material from a large scale factory, therefore, what kind of bamboo should be selected for a material.
