摘要
通过对毛果青冈播种育苗,研究毛果青冈1年生苗在苗期各器官生长的变化规律.经定期测定与回归分析,模拟苗木各器官生长与时间之间的相关关系和各器官生长与苗高生长的数学模型.结果表明:苗高、地径与生长时间呈幂函数关系,根、径、叶同苗高的生长有着直线性的相关关系;拟合模型符合毛果青冈1年生苗的生长规律,各器官间的数学模型及相关关系均达到极显著水平.
The organ growth rule of one-year-old seedlings of Cyclobalanopsis pachyloma was studied. By means of stable measurement and linear regression, the math model of the correlativity between the growth and time of seedling vegetative organs and the correlativity between their growth and the growth of height were both imitated. The imitated equation accorded with the growth rule of one-year-old seedlings of Cyclobalanopsis pachyloma. And the math model of vegetative organs and the correlativity all reached significant correlation. The results indicate that the relationship among height, ground diameter and growth time could be best described by the power model （y=at^b） while the relationship among the increment of root, diameter and leaf and the increment of height could be described by the linearity （y=a＋bx）.
