چکیده انگلیسی
To explore the reason causing low yield, poor quality of Inula helenium I., this paper investigated the influence of different remained stem heights on the yield, quality and water consumption of Inula helenium I. in Gannan plateau area using field single factor randomized block method. Research results showed that Inula helenium I. which was cut before blooming period in the last ten-day of July with remained stem height of 25â¯cm had the lowest water consumption, the best underground root traits (including main root length, root diameter, and root dry weight per plant), and the highest yield which was higher that control group by 18.73% (Pâ¯<â¯.01) Moreover, Inula helenium I. with remained stem height of 25â¯cm had the lowest ash content while the highest alantolactone content, therefore its quality was the best. The water use efficiency (WUE) of Inula helenium I. with remained stem height of 35â¯cm at September was the highest (1.12â¯kgâ

mmâ1). However, in terms of biological yield WUE and economic yield WUE, Inula helenium I. with remained stem height of 15â¯cm was the highest. Therefore, it can be concluded that remained stem height from 15 to 25â¯cm is an ideal solution, which can not only save water, but also improve yield and quality of Inula helenium I.
