| 摘 要： | 【目的】 研究不同滴灌量对荒漠地区栽培甘草根品质成分的影响，分析不同滴灌量影响甘草根品质成分的生理机制过程。【方法】 以天山北麓昌吉州荒漠地区栽培甘草为材料，于2019年在新疆农业大学科研实习基地新疆昌吉州三坪农场进行大田试验。设X0（0 m3/hm2）、X1（2 500 m3/hm2）、X2（5 000 m3/hm2）、X3（7 500 m3/hm2）和X4（10 000m3/hm2）等5种滴灌水平，检测并分析不同滴灌水平对甘草苗根中甘草酸、甘草苷、多糖、总黄酮和粗蛋白含量的影响。【结果】 当滴灌量控制在2 500~7 500 m3/hm2时有利于甘草根品质成分的积累，随着滴灌量增加品质成分也随着增加，当滴灌量超过7 500 m3/hm2时，5项品质成分含量均明显下降，完全不灌水或过高灌水时均不利于品质成分的积累。【结论】 在荒漠地区滴灌栽培甘草生产中，将滴灌量控制在5 000m3/hm2时，甘草根的甘草酸、甘草苷、总黄酮、粗蛋白和多糖等品质成分表现最优。

| Abstract: | 【Objective】 to study the effects of different drip irrigation rates on the quality components of cultivated licorice roots in desert areas， and to explore the physiological mechanism of different drip irrigation rates on the quality components of licorice roots.【Methods] the field experiment was conducted in San Ping farm， Chang Ji Prefecture， Xinjiang， a scientific research and practice base of Xinjiang Agricultural University in 2019. Five drip irrigation levels such as X0 （0 m3 / hm2）， X1 （2，500 m3 / hm2）， X2 （5，000 m3 / hm2）， X3 （7，500 m3 / hm2） and X4 （10，000 m3 / hm2） were set to detect and analyze the effects of different drip irrigation levels on the contents of glycyrrhizic acid， glycyrrhizin， polysaccharide， total flavonoids and crude protein in the roots of licorice seedlings.【Results] when the drip irrigation rate was controlled at 2，500-7，500 m3 / hm2， it was conducive to the accumulation of quality components of licorice root. With the increase of drip irrigation rate， the quality components also increased. When the drip irrigation rate was more than 7，500 m3 / hm2， the contents of five quality components decreased significantly， and it was not conducive to the accumulation of quality components when there was no irrigation or excessive irrigation.【Conclusion] in the production of Glycyrrhizauralensis cultivated by drip irrigation in desert area， the quality components of Glycyrrhizauralensis root such as glycyrrhizic acid， glycyrrhizin， total flavonoids， crude protein and polysaccharide are the best when the amount of drip irrigation is controlled at 5，000 m3 / hm2. |
