厚皮香等三个绿化树种苗期生长规律研究

The Seedlings Growing Regularity of Ternstroemia gymnanther, Acer fabric and Dendrobenthamia japonica

对三个福建乡土绿化树种厚皮香、四照花和红翅槭的生物学特性研究结果表明:厚皮香、四照花、红翅槭种子的千粒重分别为79.42g、144.59g、40.48g,三种种子均需经过预处理后播种才能发芽;预处理后,厚皮香从播种至出土平均天数约为58d,四照花为76d,而红翅槭为51d;厚皮香、四照花和红翅槭的苗高、地径与叶片数生长速度5月至10月较快,10月后放缓,11月后生长停滞。

The biological characteristics of Fujian local species, Ternstroemia gymnanther, Dendrobenthamia japonica and Acer fabric, were studied in this paper. The results showed a thousand seed weight of T. gymnanther, D. japonica and A. fabric was 79.42g, 144.59g and 40.48g, respectively. The seeds of the three species must be pretreated to germinate in time and to increase germination rate. After pretreated, the time from sowing to seedling emergence was 58 days on average for T. gymnanther, 76 days on average for D. japonica, and 51 days on average for A. fabric. For the three species, the height, ground diameter and leaf number grew rapidly from May to October, slowed down after October, and ceased growing after November.
