中文摘要：

为研究不同地域枸杞主要次生代谢物和初生代谢物的关系,以宁夏主产区中宁、银川、固原、惠农、同心等7个地域的＂宁杞1号＂为试材,研究了土壤肥力因子、枸杞果实次生代谢物甜菜碱、黄酮、类胡萝卜素等及初生代谢物枸杞多糖和总糖的变化规律及其相关性。结果表明：不同枸杞产地的土壤养分有显著差异,以主产区中宁宁安、田滩的土壤肥力状况最好。枸杞果实主要次生代谢物甜菜碱、类胡萝卜素、黄酮、维生素C及初生代谢物多糖、总糖含量在不同地域间也存在显著差异,土壤肥力较好的中宁宁安、田滩的枸杞甜菜碱、多糖含量最高,而糖碱比较低。相关分析表明,土壤全磷、全盐与类胡萝卜素积累有负相关性,速效钾与枸杞黄酮有显著的正相关性;枸杞甜菜碱与土壤有机质、全氮、全盐的含量呈极显著正相关性,速效钾与甜菜碱含量有显著相关性;多糖累积与全氮、全盐、有机质、速效钾间呈显著正相关性,而总糖含量与全盐间呈极显著负相关。因此,中宁作为枸杞道地产区,要求具有较高的土壤肥力,枸杞果实多糖和甜菜碱含量较高而糖碱比较低。

英文摘要：

In order to prove the relationship between main primary metabolites and secondary metabolites of Chinese wolfberry in different production areas of Ningxia,seven places were selected,and the effect of production areas on soil fertility,betaine,carotenoid,flavonoids,vitamin C,polysaccharide,total sugar content were studied.The results showed that the soil nutrient had significant differences with different production areas of Chinese wolfberry,Zhongning Ning＇an and Tiantan had the best soil fertility.Production areas had significant influence on main secondary metabolites betaine,carotenoid,flavonoids,vitamin C,and primary metabolites polysaccharide,total sugar content in Chinese wolfberry fruit.Chinese wolfberry fruit produced in Zhongning Ning＇an and Tiantan had the highest betaine and polysaccharide content and lower sugar alkali.Correlation analysis showed that soil total phosphorus,total salt had negative correlation with carotenoid;available potassium,flavonoids and betaine had a significant positive correlation;betaine had significant positive correlation with soil organic matter,total nitrogen,total salt content;accumulation of polysaccharide had significant positive correlation with soil organic matter,total nitrogen,total salt content,available K;total sugar content had significant negative correlation with soil salt.Zhongning as genuine producing areas had high soil fertility,the Chinese wolfberry in Zhongning had higher polysaccharide and betaine content,but lower sugar alkali.
