摘要
对药用植物红芽大戟(KnoxiavalerianoidesThoreletPitard)生态特性的研究表明,红芽大戟在中国的分布区横跨热带、南亚热带和中亚热带,垂直分布上限随分布区由东往西逐渐抬升。分布区的土壤主要是由花岗岩发育而成的砖红壤和红壤。植被类型主要为热带亚热带常绿阔叶林,部分地区演变成草坡。红芽大戟为喜光植物,在6月初至6月中旬有一生长高峰期。
In this paper, study on the ecological characters of the medicinal herb Knoxia valerianoides Thorel et pitard shows that in China ,the distribution of Knoxia valerianoides Thorel et Pitard extend through the tropical zone. South Asia subtropical zone and Central Asia subtropical zone. It is mainly distributed in laterite and red soils which orignated from granite. The limit of vertical distribution gradually ascends as the distribution area extend from east to west. The vegetation of the distribution area is tropical and subtropical evergreen broard-leaved forest. portion of which have evolved into grass-slopes. This medicinal herb is mesophyllous heliophyte, with a peak in its growth phase coinciding with that of the annual rainfall.
