羊踯躅(Rhododendron molle)生物学特性观察Ⅰ

A OBSERVATION OF BIOLOGY CHARACTERISTIC OF RHODODENDRON MOLLE I

本文采用直接观测法,对羊踯躅四年生种苗的根、茎、叶进行观察、测量、称量、计算,结果表明,羊踯躅的地下部分根颈部粗大,须根系庞大;茎分枝较少,萌生枝条和多年生枝同时并存,其生长量与落叶灌木玫瑰的生长量基本相似;叶着生在当年生枝条的顶端,叶片覆盖面积为80.2%,滞水量95.5%。

This paper reports that usese the methods directly, by the observating, measuring, weighing and computing to the root, stem and leaf of four years’ seeding of Rhododrendon molle. The results express,that the root-necks is bigger, and the fibrous root is bulky. Branches of Rhododrendon molle.is a less, sprouted new branches and perennatial branches is keep at the same time. It's same that stem's growth with Rose of deciduous bush; Leaf growing top of branches in those year. Leaf's cover area is about 80.2%,backwater capacity is about 95.5%.
