- 摘要:
- 以“沾化冬枣”为试材，在露地栽培条件下，研究了叶面喷施富硒肥对冬枣营养品质的影响。结果表明：叶面喷施富硒肥果实中硒含量显著大于对照；叶面喷施富硒肥可以显著增加冬枣可溶性糖、可溶性蛋白质、可溶性固形物的含量，同时降低了有机酸和维生素C的含量，并在一定程度上抑制了贮藏时可溶性蛋白质含量的增加。可溶性糖、可溶性蛋白质、有机酸和维生素C含量随着贮藏期延长而逐渐增多，可溶性固形物含量则随时间延长逐渐降低。相关性分析表明，可溶性糖含量与除可溶性蛋白质外的营养品质都有显著关系，维生素C和有机酸含量除与可溶性糖含量有显著相关性外，还与可溶性固形物含量呈显著负相关。综上所述，叶面喷施富硒肥能显著提高冬枣的营养品质，且随着冬枣在贮藏时由初红期向全红期转变，果实各项营养品质含量也逐渐提高。
- Abstract:
- To identify the effect of spraying Se fertilizer on ‘Zizyphus jujuba cv.Dongzao’ nutritional quality，the Jujube was grew under two levels：spraying Se fertilizer on the leaf and in the control.The results showed that,fruit selenium of treated group was significantly higher than the control group；spraying Se fertilizer could significantly increase soluble sugar，soluble protein and soluble solids content，while reducing the content of organic acids and vitamin C，and to some extent inhibited the increase of soluble protein content in storage.Soluble sugar，soluble proteins，organic acids and vitamin C content gradually increased as the storage period was extended，while soluble solids content gradually decreased.Correlation analysis showed that soluble sugar content had a significant relationship with all nutritional quality but soluble protein，vitamin C content had significant relationship with soluble sugar content and soluble solids content.In concusion，spraying Se fertilizer could significantly improve the nutritional quality of jujube，and the nutritional qualities were gradually improving from the early red phase to the all red phase.
