湿加松F2子代1年生实生苗的高生长节律可用Logistic曲线准确描述,苗高(Y)依生长天数(X)的生长模型Y=36.71/(1+53.93513e-0.02971X),其回归和相关均达极显著水平,决定系数r2=0.9930,据此将苗高年生长过程划分为生长前期、生长高峰期、生长后期.分析了5-11月苗高净生长量与主要气象因子的关系.
The high growth rhythm of 1-year-old seedlings of F2 in wet Jiazong can be accurately described by Logistic curve. The growth model Y = 36.71 / (1 + 53.93513e-0.02971X) according to the growth days (X) And the correlation reached an extremely significant level, the coefficient of determination r2 = 0.9930, thus the annual growth process is divided into pre-growth, peak growth and later growth.Analysis of net growth and main meteorological factors from May to November relationship.
