左家天然次生林中天南星的生长规律

为了研究天南星生长的生态环境。从而在半野生条件下对其驯化栽培。以左家为例对天然次生林中生长的天南星科植物进行调查。结果表明，左家天然次生林中有4种野生天南星。多生长在土壤疏松、肥沃含腐殖质高的灌木林、灌丛或草丛、山沟等比较阴湿的环境下。东北天南星的生长期为4月下旬至6月末。平均株高43cm；齿叶东北天南星的生长期为5月初至6月末，平均株高44cm；异叶天南星的生长期为5月初至9月末，平均株高85cm；朝鲜天南星的生长期为5月中旬至9月末，平均株高76cm。为天南星的人工栽培提供理论基础。

Investigation of Growth Regularity of Arisaema in the Secondary Forest of Zuojia

In order to study the ecological environment ofA risaema growth for the domestication and cultivation under the semi-wild conditions, we examined the second-growth forest Arisaema in Zuojia. The results indicated that there were 4 types of wild Arisaema in the secondary forest of Zuojia, which grow in the dank shrubbery, bosk, brushwood, upland channel etc. where loose fertile soil was found.Arisaema amurense＇s growing season is from the late April to end-June, and the average stem height is 43cm; Arisaema amurense riserrata＇s growing season is from the early May to the end-June, and the average stem height is 44cm; Arisaema heterophyUum＇s growing season is from the early May to the end-September, and the average stem height is 85em; the A risaemapeninsulae＇s growing season is from the mid-May to end-September, and the average stem height is 76cm. This paper can provide the theoretical basis for A risaema＇s cultivation.
