不同硒肥类型对毛葡萄果实硒含量及品质的影响初探

Effects of Different Selenium Fertilizer on Selenium Content and Quality of Vitis quinquangularis Rehd.

摘要: 为开展广西地区毛葡萄富硒研究，本试验通过采用“聚福硒”、“泰山葡萄专用补硒叶面肥”、“中农6号”、“康熙宝有机水溶肥料”四种常见硒叶面肥，研究其对毛葡萄富硒效果及品质影响。结果表明：四种硒肥富硒效果表现为“聚福” > “中农” > “康熙” > “泰山”，与对照(CK)相比分别提高了96.08%，85.56%，71.12%，54.11%；不同类型硒肥对毛葡萄果实总酸、维生素C、总糖影响不尽相同；总糖含量仅“康熙”处理比对照增加0.89%，其余三种处理却比对照低；维生素C含量除“中农”比对照低其余均显著增高；总酸含量“聚福”和“中农”分别比对照显著增加13.21%和18.22%，而“泰山”和“康熙”与对照相当但差异不显著。综合各种因素考虑，我们认为“康熙宝”牌硒肥为本次试验最佳肥类。

Abstract: In order to carry out the research on the Se-rich of Vitis quinquangularis Rehd. in Guangxi, this test used four selenium fertilizers of “Jufuxi”, “Taishan special selenium supplement foliar fertilizer for grape”, “Zhongnong No. 6”, “Kangxibao organic water soluble fertilizer” to study the effects on grape quality and selenium content. The results showed that: the selenium enriched effect of the four selenium fertilizers was “Jufu” > “Zhongnong” > “Kangxi” > “Taishan”, increased by 96.08%, 85.56%, 71.12% and 54.11% respectively compared to the control (CK); the effects of different selenium fertilizers on total acid, vitamin C and total sugar were different; the total sugar content of the “Kangxi” treatment was higher than the control by 0.89%, while the remaining three treatments were all lower; all treatments except “Zhongnong” had significantly increase than the control on the vitamin C content; the total acid content of “Jufu” and “Zhongnong” was higher than the control by 18.22% and 13.21%, but “Taishan” and “Kangxi” showed little differences to the control. We think that the selenium fertilizer of “Kangxi Bao” brand was the best fertilizer in this test.
