Although the cellular structure, the Chemical composition and the physical and mechanical properties are similar with the solid wood, but bamboo belongs to grass family since its growth and reproductive pattern is similar with the regular grass and much different from the wood. Bamboo’s rhizome keeps stretching and growing under the ground, then new bamboo shoot will be pregnant and grow up from the rhizome root, from the bamboo shoot to grow up to be a 18 meter long bamboo only need 1 month. When the bamboo is young before the age of 4, the bamboo leaf will absorb CO2(Carbon Dioxide) and N2(Nitrogen) from the air and create nutrition through photosynthesis, then convey the nutrition to the rhizome and promote the rhizome stretch and reproduce new bamboo shoot.but after the bamboo is older than 5 years, the photosynthesis function of the leaf becomes weaker and weaker, and the bamboo stem and leaf need to get nutrition from the rhizome and which will affect the reproduction of the rhizome. When the bamboo is older than 7 years, the bamboo texture will become deteriorating yearly and can’t use for industrial production, then the bamboo will die very soon. So the best harvesting time for industrial usage is when the bamboo is between 4-6 years old.
Thus it can be seen, bamboo grows very quickly and is a sustainable nature resource, if the mature bamboo can be harvest yearly, not only it won’t destroy the environment and the bamboo growth, but it is good for the its reproduction.
