Extended Abstract
Introduction and Objective: Dracocephalum lindbergii is one of the native medicinal plants in Lamiaceae family of Iran and it is growing natural habitats in the north east of Iran. In order, this plant know ecological characteristic for introduce and artificial revegetation on dryland farming and then use in medical industries. Such as this plant natural sites were controlled of destroying. This study was executed in rangeland and dryland artificial revegetation from 2018 to 2021 in Bojnourd
Material and Methods: In the range site, the studies were climatically (precipitation, temperature, climate) characteristic and vegetable variation including plant height, length and wide of diameter, density, Canopy cover percentage and Estimating biomass, physical and chemical analyses of the soil. In order to artificial revegetation the medicinal species of Dracocephalum lindbergii, a special dryland was selected at an altitude of 1500 meters above sea level on the northern slope in Godali Salakh area. Planting was done by two methods of plant division and transplanting. Statistical analysis of the obtained data was performed using independent t-test and principal component analysis.
Results: The results revealed that this species could be adapted for regions with semiarid- cold climate, annual rainfall average of 295 mm and annual temperature average of 11.28 c°. This species has dispersed in north, south, east and west slope and altitude 1200- 1900 m of sea level in rocky areas. The soil of area is calcareous with sandy-loom texture. Principal component analysis (PCA) showed that the variables of sand, silt, lime percentage, organic matter and cation exchange capacity had significant correlations with the first axis and explained the 37.2% variation. In the site and dryland artificial revegetation, Average of canopy covers and production were 0.147, 57.68% and 2.83, 1619.68 kg in hectare respectively.
Conclusion: The present survey findings can property a suitable management approach for farmer, planners and policymakers to make a sound decision regarding the soil and plant protects in similar areas.
