摘      要：[Objectives]This study was conducted to choose a selenium-rich foliar fertilizer suitable for the selenium-rich fruit and vegetable industry in Guangxi.[Methods]With Lingfeng wine grapes as test materials,such four kinds of selenium fertilizers as Jufu Selenium(JF),Taishan Weed Fertilizer(TS),Zhongnong No.6(ZN) and Kangxibao(KX) were used as exogenous selenium for the experiment of selenium-enriched grapes.[Results]The selenium contents in the grape fruit applied with the selenium fertilizers increased by 1.2-16.8 times compared with the control (CK),and JF and ZN had a better selenium-enriching effect and produced the fruit having the selenium contents reaching 75.85 and 45.79 μg/kg,*** selenium fertilizers can improve some quality indexes of grapes in that spraying JF on the leaves can significantly increase the total sugar content of the grapes while reducing the total acid content and spraying ZN significantly improved the vitamin C content of the *** the delay of harvesting,the selenium content,total sugar content and total acid content of the Lingfeng grape fruit decreased,while the grapes sprayed with ZN showed the total sugar content increased slightly and the total acid decreased greatly.[Conclusions]It is suggested that if you plan to harvest at the right time,you can use Jufu Selenium as the exogenous fertilizer for selenium-enriched grapes;and if you want to postpone harvesting,you can use Zhongnong No.6 as the selenium fertilizer.
