猪苓是一种常用的中药材,自古至今靠采挖野生供药用。由于自然资源减少,供需矛盾日趋突出。为实现人工培植,进行野生猪苓生态调查和生物学特性的研究,掌握其生长繁殖的规律是必要的。现将调查结果报导如下: 一、猪苓的生态环境1.海拔:野生猪苓多处于海拔1000～2000公尺地段。但云南省点苍山海拔2500～3500公尺的山腰有分布,这可能与该地区受孟加拉湾海洋气候的影响有关。2.坡向:云南、四川发现阳坡生长猪
Polyporus umbellatus is a commonly used Chinese herbal medicine, ancient mining by digging wild for medicinal purposes. Due to the reduction of natural resources, the contradiction between supply and demand has become increasingly prominent. In order to realize the artificial cultivation, it is necessary to carry on the research on the ecological investigation and the biological characteristics of Polyporus umbellatus and to grasp its law of growth and reproduction. The survey results are reported as follows: First, the Polyporus ecology 1. Altitude: wild Polyporus more at an altitude of 1000 to 2000 meters section. However, there is a distribution of mountainsides of 2500-335 meters above sea level in Dian Cangshan in Yunnan Province, which may be related to the influence of the marine climate in the Bay of Bengal in the area. 2. Slope: Yunnan, Sichuan found that the Yangpo growth pigs
