Abstract:

According to the investigating of the factors of stands, shoots emergence and new culms in 96 plots of high-yield bamboo forest built in distributive area of Phyllostachys heterocycla cv.pubescens in Fujian Province, the biomass of every organs, D. B. H., height, and node number of 96 standard culms were measured. Based on these datas, the forecasting models of shoot emergence, new culms, and the biomass of every organs, have been established by mono regression models and multiple regression models.The weight, basal diameter and maximum diameter of 277 spring shoots have been determined. The shoot weight estimation model also has been established, which is significantly correlative by F test, high precision and reliable, and can be applied to forest production.
