水杉一年生播种苗生长规律探讨

本文阐明了水杉一年生播种苗苗高、地径的变化规律及其与环境因子的关系。将水杉苗年生长过程划分为出苗期、生长初期、生长盛期和生长后期四个生长时期,并模拟出其高生长模型及径生长模型。

Yearly Growth Rhythm of Metasequoia Seedling

In this paper the variation patterns of seedling height and Collardiameter of metasequoia andtheir relationships to enviroment factors were studied. The yearly growth process can be dividedinto emergence period, early growth period, vigorous growth period and later growth period. Thegrowing processes of the height and diameter were simulated.
