Abstract
Dracocephalum kotschyi Boiss. is one of the medicinal and aromatic plants that is found in natural sites of mountainous areas. This plant is important because of it's high content of essential oil. In traditional medicine, this plant is used for fever reduction, joints pain, rheumatism, inflammation against and sore recovery. The present study was done to introduce ecological characteristic and dense cultivation on farm land and then using this plant in medicinal industries. This study was carried out in rangelands of Bojnourd in 2008. In this site, different parameters like climate characters, geology, stand type, codominant plant and vegetable variation, physical and chemical analysis of the soil were determined. The results showed that Dracocephalum kotschyi could be adapted in regions with semiarid cold climate, annual rainfall average of 320 mm and annual average temperature of 10.22 °C. Dracocephalum kotschyi have dispersed in northern and north- west slope and altitude 1600-1800 m of sea level in rocky area. The physical and chemical analysis of soil showed that the soil was very shallow with loomy texture, pH= 7.57- 7.6, EC= 0.555 ds/m and CEC= 11.475- 11.9 Cmol/kg. The stand type was Stachys inflata- Festuca ovina and the codominant plants were over 58 species. Average of canopy covers and density were 0.122%, 361 shrubs in hectare, respectively.
