摘要
采用非线性回归拟合方式对海州常山1年生播种苗生长曲线进行logistic模型拟合,苗高和地径生长曲线的拟合相关性极显著,用数学模型来确定海州常山苗木生长的速生期,将生长期划分为四个时期。对见报的其他繁育技术研究进行了综述,提出实际生产中以播种育苗作为海州常山繁育方法的首选。
Fitting growth curve of 1-year Clerodendrum trichotomum Seedling of logistic model by the method of nonlinear regression way. The correlation coefficient of high and ground diameter growth curve had reached a significant level. Determine the fast-growing period of seedling growth of C. trichotomum by the mathematical model. Process of growth will be divided into four periods. Some researches in other cases of breeding technology that have been reviewed were summed. The seedling breeding methods as the first choice in the practical production was put forward.
