Problems solved by technology

In this scheme, amino acid fermentation waste liquid is degraded into small molecular organic matter, and inorganic selenium uses sodium selenite or sodium selenate or selenium ore powder, and small molecular organic matter forms organic state with sodium selenite or sodium selenate or selenium ore powder The effect of selenium is not ideal, so the effect of the formed selenium-enriched organic carbon fertilizer on crops is not weak

Abstract

The invention provides selenium liquid fertilizer. The selenium liquid fertilizer comprises organic carbon, organic nutrients, nitrogen fertilizer, microelement fertilizer, a nano selenium source anda chelating agent which are in a weight ratio of (50-90): (5-10): (10-25): (1.3-1.7): (0.1-0.5): (0.1-0.5); the nano selenium source comprises nano selenium and microorganisms, wherein the nano selenium accounts for 40-50% by weight of the nano selenium source, and the microorganisms account for 5-10% by weight of the nano selenium source. The invention also provides a preparation method of the selenium liquid fertilizer. The selenium liquid fertilizer can be effectively absorbed and utilized by crops, thereby increasing the selenium content in the crops and products as well as the crop yield.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a selenium liquid fertilizer and a preparation method thereof. Background technique [0002] CN108178708A discloses a selenium-enriched organic carbon fertilizer and a preparation method thereof. The invention uses amino acid fermentation waste liquid, amino acid fermentation waste liquid and inorganic selenium as raw materials to produce selenium-enriched organic carbon fertilizer, mainly utilizes redox reaction to degrade amino acid waste liquid into nano-scale small molecular organic matter, and under weakly alkaline conditions, It reacts with selenium compounds to form organic selenium. In this scheme, amino acid fermentation waste liquid is degraded into small molecular organic matter, and inorganic selenium uses sodium selenite or sodium selenate or selenium ore powder, and small molecular organic matter forms organic state with sodium selenite or sodium selenate or se...
