| 摘 要： | 通过对暴马榆1年生播种苗生长进行定期观测,采用Logist曲线对苗高生长过程进行拟合,建立生长模型,经对生长模型进行计算分析,结果表明:暴马榆1年生苗高生长相关系数达0.994 369,拟合效果显著。1年生暴马榆播种苗高生长过程可划为生长前期、速生期和生长后期。生长前期约35d,苗木累积生长量为15.3cm,累积生长率为23%;速生期约48d,苗木累积生长量为40.8cm,累积生长率为61.3%;生长后期约38d,苗木累积生长量为10.5cm,累积生长率为15.7%。

Growth Observation of One-year-old Cerasus maxiowiczii seedings and its management in seedlings stage |

| Abstract: | Seedling growth of one year planted Cerasus maxiowiczii was observed,and growth model was estab-lished using Logist curve to fit on the seedling height growth process.Through calculation and analysis on the growth model,the results showed that correlation coefficient of one year C.maxiowiczii seedling height growth reaches 0.994 369,and the fitting effect is remarkable.Seedling growth process is divided into three stages,inclu-ding early growth stage,fast growth stage and late growth stage.Early growth stage is 35 d,with 1 5.3 cm cumula-tive mass growth and 23% cumulative growth rate.Fast growth stage is 48 d,with 40.8 cm cumulative mass growth and 61.3% cumulative growth rate.Later growth stage is 38 d,with 10.5 cm cumulative mass growth and 1 5.7% cumulative growth rate. |
