构树叶粗蛋白年变化呈现两个高峰,依次在4月和8月时出现,其值分别为25.4%和21.2%;皮粗纤维年变化也出现两个高峰,依次在4月和10月时出现,其值分别为45.7%和41.2%。构树皮生物量的分配为中度干扰>强度干扰>弱度干扰,这说明适宜强度的干扰可以促进构树萌枝的产生。根据研究结果提出了构树叶、皮的经营技术。 The annual changes of the crude protein in leaves showed two peaks, which appeared in April and August in turn, with the values ​​of 25.4% and 21.2% respectively. The annual changes of the crude fiber also showed two peaks, which were in April and October Appear, its value is respectively 45.7% and 41.2%. The distribution of bark biomass was moderate disturbance> intensity disturbance> weak disturbance, which indicated that the disturbance of appropriate intensity could promote the emergence of broussonetia papyrifera. According to the results of the study made of tree leaves, skin management techniques.
