| 摘 要： | Objective] The aim of this study is to investigate the optimum application amount of nitrogen in Lycium barbarum based on considering the relationship between main secondary metabolites and polysaccharide.Method]Under field conditions,the effects of different application amounts of nitrogen on main secondary metabolites of betaine,carotenoid and flavone of Lycium barbarum and the relationship between main secondary metabolites and polysaccharide.Result] The main secondary metabolites of betaine,carotenoid and flavone of Lycium barbarum varied under different application amounts of nitrogen.The proper application amount of nitrogen(600-900 kg/hm2)was beneficial to the formation and accumulation of secondary metabolites such as carotenoids.Correlation analysis results showed that polysaccharide were negatively correlated with betaine,carotenoid and flavone at significant probability level.Conclusion]Considering the relationship between the output and quality of the fruits of Lycium barbarum,the optimum nitrogen application amount should be 600-900 kg/hm2.

| Abstract: | Objective] The aim of this study is to investigate the optimum application amount of nitrogen in Lycium barbarum based on considering the re-lationship between main secondary metaholites and polysaccharide. Method] Under field conditions, the effects of different application amounts of nitro-gen on main secondary metabolites of betaine, carotenoid and flavone of Lycium barbarum and the relationship between main secondary metabolites and pol-ysaccharide. Result] The main secondary metabolites of betainc, carotenoid and flavone of Lycium barbarum varied under different application amounts of nitrogen. The proper application amuant of nitrogen (600 -900 kg/hm2) was beneficial to the formation and accumulation of secondary metabolites such as carotenoids. Correlation analysis results showed that polysaccharide were negatively correlated with betaine, carotenoid and flavone at significant probability level. Conclusion] Considering the relationship between the output and quality of the fruits of Lycium barbarum, the optimum nitrogen application a-mount should be 600 -900 kg/hm2. |
