Paddy rice rice blast-resistant selenium-rich yield-increasing agent and preparation method thereof

Abstract

The invention discloses a paddy rice rice blast-resistant selenium-rich yield-increasing agent and a preparation method thereof. The paddy rice rice blast-resistant selenium-rich yield-increasing agent comprises the following raw materials by weight: 30-50 parts of ammonium biphosphate; 45-65 parts of monopotassium phosphate; 6-12 parts of boron fertilizer; 8-12 parts of selenium fertilizer; 3-6 parts of humic acid; 3-6 parts of lithium sulfate monohydrate; 10-20 parts of sodium metasilicate pentahydrate; 0.3-1.2 parts of diclofenac sodium; 0.1-0.3 parts of glycyrrhizic acid; 1-3 parts of p-chloro-m-xylenol; 0.5-1.5 parts of flucytosine; 6-9 parts of betaine; 0.2-0.4 parts of diphenhydramine; and 0.1-0.4 parts of cromolyn sodium. The paddy rice rice blast-resistant selenium-rich yield-increasing agent of the invention is strong in pertinency, solves various prominent problems in paddy rice plantation, and has various effects of rice blast resistance, seed setting rate increasing, thousand seed weight increasing, yield increasing, polished rice rate increasing, rice protein content increasing, rice selenium content increasing, and the like.
