摘要:

【目的】 研究不同海拔高度对芜菁营养成分的影响,分析芜菁在青海省的适生区范围,为芜菁种植选择最佳适生区以及提高资源利用率提供重要的依据。【方法】 选取不同来源的13份芜菁为材料,比较分析芜菁在青海省西宁市(海拔2 261 m,A处理)、青海省海南藏族自治州贵南县(海拔3 100 m,B处理)和青海省玉树藏族自治州玉树市小苏莽乡(海拔3 750 m,C处理)3个不同海拔的地区种植对其营养成分的影响。【结果】 随着海拔高度的增加,芜菁的可溶性双缩脲蛋白质含量增加、总糖含量增加、亚硝酸盐含量增加、硝态氮含量降低、含水量降低,而海拔高度对芜菁抗坏血酸含量、总抗氧化能力和粗纤维含量没有显著影响,表现为在B处理下,抗坏血酸含量高于其他两个地区,总抗氧化能力更强,粗纤维含量比较高。海拔高度与总糖、亚硝酸盐含量呈极显著正相关,与可溶性糖、硝态氮含量呈极显著负相关;土壤理化性质与可溶性蛋白、可溶性糖、总糖、硝态氮和亚硝酸盐含量具有相关性。【结论】 在不同海拔地区芜菁含有的营养成分间存在显著差异,4份材料(1402、W30、昌都和玉树芫根)在海拔2 261和3 100 m的地区各营养成分含量表现更优,1份材料(W22)在海拔为3 750 m的地区营养含量表现更佳。9个营养指标中有4个与海拔高度达到显著性相关;土壤理化性质与营养成分含量具有相关性。

Abstract:

【Objective】 To clarify the influence of different altitudes on the nutrients contained in turnips and determine the best suitable growing areas for turnips,cultivation,this study provides the important basis for selecting the best suitable growing area and improving the resource utilization rate for turnip planting in the future.【Methods】 In this study,13 different sources turnips were selected as test materials,the effects of turnip cultivation on their nutritional content were compared and analyzed in three different altitude areas:Xining City,Qinghai province(2,261 meters above sea level,treated by A),Guinan Conty,Tibetan Autonomoas prefecture,Hainan Province(3,100 meters above sea level,treated by B),and Xiaosumang Township,Yushu City,Tibetan Autonomous Prefecture,Qinghai Province(3,750 meters above sea level,treated with C).【Results】 The results showed that with the increase of altitude,the soluble protein content,total sugar content,nitrite content increased,nitrate content decreased,nitrate nitrogen content decreased,and water content decreased,while altitude had no significant effect on the ascorbic acid content,total antioxidant capacity and crude fiber content of turnip,which showed that under B treatment,the ascorbic acid content was higher than that in the other two regions,the total antioxidant capacity was stronger,and the crude fiber content was relatively high.Correlation analysis showed that altitude was significantly positively correlated with total sugar and nitrite content,while negatively correlated with soluble sugar and nitrate nitrogen content.Soil physical and chemical properties were correlated with the contents of soluble protein,soluble sugar,total sugar,nitrate nitrogen and nitrite.【Conclusion】 There are significant differences in the nutrient content of turnips at different altitudes.Four materials(1,402,W30,Changdu and Yushu turnips) showed better nutrient content at 2,261 and 3,100 meters above sea level,and one material(W22) showed better nutrient content at 3,750 meters above sea level.Four of the nine nutritional indicators were significantly correlated with altitude; Soil physical and chemical properties were correlated with nutrient content.

Key words: turnips; altitude; nutritional content; correlation
