叶面补硒对红美人硒含量的影响

Effect of foliar selenium supplementation on selenium content in Hongmeiren

硒是人体必不可少的微量元素之一。在贫硒地区实现富硒果品的生产是功能型果品生产的重要目标。尽管如此,无机硒大多对人类健康有害,生产安全的富硒果品的方法已成为关键。浙江是柑橘的主要产区,同时也是贫硒地区,因此,富硒红美人柑橘拥有巨大的市场潜力。本实验采用了叶面喷施的补硒方式,研究了叶面补硒对红美人果实硒含量的影响,评价了果实的含硒量是否安全。结果表明,喷施亚硒酸钠溶液可提高红美人果实的硒含量;每隔15 d叶面喷施植物硒元素营养液(1次、2次、3次),连续喷施3次果实硒含量最多。

Selenium is one of the essential trace elements in the human body.The production of selenium rich fruits in selenium poor areas is an important goal of functional fruit production.Nevertheless,most inorganic selenium species are harmful to human health,and the method of producing safe selenium rich fruits has become crucial.Zhejiang Province is a major citrus production area and also a selenium poor area,so selenium rich Hongmeiren has huge market potential.This experiment used foliar spraying to supplement selenium,studied the effect of foliar selenium supplementation on the selenium content of Hongmeiren fruit,and evaluated whether the selenium content of the fruit was safe.The results showed that spraying sodium selenite solution could increase the selenium content of Hongmeiren fruit,spraying plant selenium nutrient solution on the leaf every 15 days(once,twice and three times),and continuously spraying three times to obtain the highest selenium content in the fruit.
