| 摘 要： | 对构树叶构件种群生长动态变化及其粗蛋白年变化进行的研究结果表明:叶构件种群的生长过程呈"S"型曲线变化,3月上旬发芽展叶,现叶方式为"爆发型",4～6月生长迅速,同时4月开始慢慢落叶,12月落叶结束;构树叶粗蛋白年变化呈2个高峰,分别在4月和8月时出现,其叶粗蛋白值分别为25.4%和21.2%.在每年4月和8月采集构树叶做饲料,其经济效益最高.

| Abstract: | The results from studying growth dynamic change of Broussonetia papyrifera leaf modular population and its annual variation of crude protein content indicates that the growth process of Broussonetia papyrifera leaf modular population is a S curve,the leaves start to grow in an eruption pattern in the first ten-day period of March,rapidly grow from April to June,and begin to defoliate slowly from April;and its leaf crude protein content in April and August is 25.4% and 21.2% respectively.Therefore,the econom... |
