3个种源花椒1年生实生苗年生长节律观测与模拟

Observation and Simulation of the Growth Rules of One-year-old Zanthoxylum bungeanum Seedlings from Three Provenances

对同一栽培条件下3个不同种源花椒的年生长规律进行了观测比较。结果表明,各种源花椒的多项生长指标方程拟合效果显著;不同种源生长节律有所不同,但总体上可划分为5个阶段:出苗期、缓慢生长期、速生生长期、生长后期、休眠期。

Growth rules of one-year-old seedlings of Zanthoxylum bungeanum from three different provenances were observed and simulated. The growth curves of seedling height, ground diameter and number of leaflets were built with different equations, and selected regression equations. The results indicated that the Simulation performances of different growth indices were perfect. Although the growth rhythms of the seedlings from different provenances were different,in general it could be divided into 5 stages： young-seedling, slow-growing, fast-growing, late-growing, and dormancy stages.
