Abstract

In this paper, seedling of non-energy-plant Stevia rebaudiana Hemsl in greenhouse is designed as the research subject. After its plant height, fresh weight, root length, leaf number, soil moisture content and other indexes are measured, seedling Stevia is found in germination period, slow growing period after germination, rapid growing period and then field transplanting period. In the meantime, root length of Stevia shows a linear increasing tendency with increasing growing time; plant height and fresh weight show an exponential increasing tendency with increasing growing time; leaf number shows a linear increasing tendency with increasing growing time; fresh weight and plant height present a linear relationship, that is, the higher the plant height is, the heavier the fresh weight is and the larger the plant biomass is; plant height and root length present a logarithmic function relationship; fresh weight and root length present an exponential relationship, namely, plant height and leaf number above the ground mainly develop and root length does not change greatly when root length increases to 30mm; and soil surface moisture content should be above 20% (2mm) consistently so as to meet the moisture condition for the germination of Stevia in greenhouse.
