Abstract
Objective]For understanding growing conditions of Dracocephalum rupestre Hance,in order to introduction and cultivation.[Methods]the origin of climatic conditions,longitude and altitudeof four original habitat and a testing ground in Shanxi were tested,and 1 2 soil nutrient contents of 5 producing areas were determined.[Results]The results showed that:(1)Dracocephalumrupestre Hance origin elevation mainly were between 1 900~2 400 m,annual sun-shine hours was about 2 800 h,annual rainfall was between 400 mm and 650 mm.So it liked light,cool and more hu-mid environment.(2)Soil of origin habitat of Dracocephalumrupestre Hance had a higher organic matter content, with an average of 70 g·kg-1 .Soil pH value was neutral weak acid and alkaline,the average value was 7.01 .(3)The average content of natively total soil nitrogen,phosphorus,potassium,exchangeable calcium,exchangeable magnesi-um,manganese and effective state,effective state Fe,available Cu,Zn effective were 0.308%,21.1 mg·kg-1 , 217 mg·kg-1 ,0.526%,121 mg·kg-1 ,13.1 mg·kg-1 ,36.48 mg·kg-1 ,0.47 mg·kg-1 ,1.50 mg·kg-1 .Potassium, manganese and effective state Mn,effective state Fe and magnesium content of the original habitat soil interactivity were higher than the average level of the soil in Shanxi;total nitrogen,phosphorus,Zn content were consistent with the average level of the soil in Shanxi;interactivity Ca content was less than soil average Shanxi.[Conclusion]By the a-nalysis of environment and soil nutrients of Dracocephalum rupestre Hance,its growth condition was high altitude, cool,moist,sunshine long time,and low soil salinity,high organic matter content.关键词
