摘要
根据物候学和胚胎学的研究结果,研究了杉木种子产量同各敏感期主要气象因子的相关关系,并应用逐步回归的方法,建立了预测尤溪经营林场杉木种子园种子产量的数学模型.还利用所建模型拟合了历史产量.
Based on the researches of phenology and embryology of Canninghamia lanceolata, this paper has studied the relations between seed yield and main meteorological factors in each sensitive period and developed a mathematical model for forecasting the seed yield of Cunninghamia lanceolata seed orchard in Youxi Jingying Forest Farm by means of stepwise regression. The forecasting result of the historical seed yields shows that the model is accurate and practicable.
