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 results of phenology and embryology, the relationship between Chinese fir seed yield and the main meteorological factors during the sensitive period was studied. The mathematical model for predicting the seed yield of Chinese fir seed orchard was established by applying stepwise regression. Historical models have also been fitted using the model built.
