Paddy rice selenium-rich foliar fertilizer

Abstract

The invention relates to a paddy rice selenium-rich foliar fertilizer. The paddy rice selenium-rich foliar fertilizer is characterized in that 1L of the paddy rice selenium-rich foliar fertilizer contains 1-10g of sodium selenite, 1-10g of a nonionic organosilicon surfactant, and 2-20g of water-soluble azone. The paddy rice selenium-rich foliar fertilizer allows selenium-rich rice with selenium according with standards to be produced through once spraying on paddy rice foliages of the heading stage. The addition of the nonionic organosilicon surfactant which can reduce the surface tension of an aqueous solution to components of a selenium-rich spraying agent, and the synergism of the plant foliage moistening adhesion promotion and the penetration promotion are used to convert selenium into organic selenium which can be enriched in grains.
