四种金沙江干热河谷乡土植物生物学特性观察

Observation on Biological Characteristics of Indigenous Plants in the Hot and Dry Valley of Kingsa River

对金沙江干热河谷乡土植物扭黄茅(Heteropogon contortus)、蔓草虫豆(Cajanus scarabaeoides)、牛角瓜(Calotropis gigantea)、戟叶酸模(Rumex hastatus)的生育期、株高、产草量、植株形态等各项指标进行观测研究,为进一步开发利用提供依据。

For further development and exploitation of four indigenous plants （Heteropogon contortus, Cajanus scarabaeoide, Calotropis gigantea （L.） Dryand and Rumex bastatus）, study on their biological characteristics regarding bearing, height, yield and plant morphology was conducted in the hot ＆ dry valley of Kingsa river, Sichuan province.
