| 摘 要： | 通过对12个楸树杂种无性系的研究表明,楸树杂种无性系苗期苗高、地径生长节律符合"S"型曲线,其生长进程均表现出明显的"慢-快-慢"的节律。采用Logistic生长方程对动态生长节律进行拟合,相关系数达0.99以上,拟合的效果极显著。楸树速生期的天数占整个生长期的比重为47%,速生期内的生长量占整个生长量的60%以上;楸树杂种无性系苗高生长峰值出现在7月中旬,地径峰值在7月上旬,苗高速生期开始时间为6月上旬,地径速生期开始时间5月下旬。苗高速生期结束时间为9月初,地径速生期结束时间在8月下旬,苗高速生期持续天数86 d,地径速生期持续天数89 d。 |

| Abstract: | The research of 12 hybridal clone of Catalpa bunge showed that the growth rhythm of the seedling height during seedling stage and ground diameter matched perfectly with S curve,the growth process was showed obviously slow-fast-slow rhythm.The dynamic growth rhythm was fitted by Logistic Growth Equation and the correlation coefficient was above 0.99,reaching significant level.The rapid growth period was accounted for 47% of the total growth period and the amount of growth during this period was accounted for... |
