Study On The Biomass Of Different Origins In Moso Bamboo Base On Fertilizer Regulation

In this paper, based on the different origin moso bamboo as the research object of Yongfeng Guanshan forestry station in Jiangxi province, the moisture content of various organs, the biomass allocation proportion, regression models, individual biomass and regression models were studies of the different origin moso bamboo.The results show that:1.Dazhoushan artificial moso bamboo and Dongmaokeng natural moso bamboo aboveground part each organ average moisture content order of leaves>culm>branchs, artificial moso bamboo each organ average moisture content is greater than natural moso bamboo each organ average moisture content.2.There is some certain relationship in the plant biomass allocation in different organs of Dazhoushan artificial moso bamboo and Dongmaokeng natural moso bamboo, results showed that, because of the support bamboo body bamboo culm plays an important role, after long-term accumulated, culm biomass distribution of the proportion of the largest, branch, leaf in the process because of metabolism or grow consumption, the biomass allocation proportion is relatively minor. Each standard in bamboo for sample habitat conditions and different fertilizer processing show different differences, comprehensive data get organs for biomass allocation proportion:culm>branchs>leaves, of which continents Dazhoushan artificial moso bamboo, the average biomass allocation ratio in culm 80.36%,the average biomass allocation ratio in branchs 13.32%,the average biomass allocation ratio in leaves 6.04%; Of which continents Dongmaokeng natural moso bamboo, the average biomass allocation ratio in culm 82.34%, the average biomass allocation ratio in branchs 11.91%, the average biomass allocation ratio in leaves 5.75%.3.Different origin and fertilizer moso bamboo individual average biomass exist in the following relations:Under different fertilizer processing, natural moso bamboo individual average biomass is greater than artificial moso bamboo individual average biomass. Under 39% Slag fertilizer processing, artificial moso bamboo and natural moso bamboo individual average biomass gap is the largest. Under 45% Slag fertilizer processing, minimize differences.4.The correlation and regression analysis between the biomass allocation ration in different parts of a bamboo and stand index showed that:1) Except the biomass allocation ration in bamboo leaves, there are significant linear correlations between DBH and biomass allocation rations in different organs. The linear correlation between the bamboo culm biomass allocation ratio and DBH is significant, in which the biomass allocation ratio of bamboo culm increases with DBH. the biomass allocation ratio of the bamboo branchs increases with DBH decreased. Through to the various common function bamboo biomass allocation proportion and DBH fitting to find fitting equation coefficient of determination close to zero, account for there is no obvious linear correlation between DBH and the bamboo leaves biomass allocation ratio.2) The linear correlation between the bamboo culm biomass allocation ratio and the bamboo height is significant, the linear correlation between the bamboo leaves biomass allocation ratio and the bamboo height fitted the worst, determination coefficient is almost zero. The biomass allocation ratio of bamboo culm increases with the bamboo height, the biomass allocation ratio of bamboo branchs and increases with the bamboo height decreased. The bamboo leaves biomass allocation ratio datas are scattered, there is not exist linear correlation between them.
