Method for preparing amino acid foliar fertilizers from distillers' grains

Abstract

The invention provides a method for preparing amino acid foliar fertilizers from distillers' grains. The method includes steps of (1), cooking the distillers' grains in a pot filled with water, continuing cooking the distillers' grains for 20 minutes after the water in the pot is boiled, fetching the distillers' grains out of the pot, cooling the distillers' grains until the temperatures of the distillers' grains reach the room temperature, and filtering and drying the distillers' grains to obtain distillers' grain powder; (2), adding enzyme bacterium inoculants and the distillers' grain powder obtained in the step (1) into a fermentation vat, stirring the distillers' grain powder and the enzyme bacterium inoculants until the distillers' grain powder and the enzyme bacterium inoculants are uniform, adding brown sugar water and rice vinegar into the fermentation vat, stirring the brown sugar water and the rice vinegar until the brown sugar water and the rice vinegar are uniform, covering an opening of the fermentation vat with three layers of gauze, tying the gauze by the aid of strings, placing the fermentation vat in an indoor environment and fermenting materials in the fermentation vat; (3), stirring the materials in the fermentation vat once on a daily basis from the fifth day to the sixth day after fermentation is started, instantly covering the opening of the fermentation vat after the materials in the fermentation vat are stirred, stopping fermenting the materials once blocks are formed by the materials in the fermentation vat and the materials are odorless, opening the gauze and drying the materials; (4), transferring the dried fermented materials into a container, soaking the dried fermented materials in brown sugar water for 20 days, fetching the materials out of the brown sugar water, separately packing the materials to obtain the amino acid foliar fertilizers, and storing the amino acid foliar fertilizers in shade and dry places. The method has the advantages of simplicity in operation and low preparation cost.

Description

technical field [0001] The invention relates to a method for preparing amino acid foliar fertilizer by utilizing distiller's grains. Background technique [0002] Amino acid foliar fertilizer is a foliar fertilizer containing amino acid active factors. It uses plant amino acids as a substrate, uses its large surface activity and adsorption and retention capacity, and adds nutrients needed for plant growth and development (nitrogen, phosphorus, potassium, iron, Copper, manganese, zinc, aluminum, boron, etc.), through complexation and complexation to form organic and inorganic compounds. This kind of fertilizer can not only maintain the slow release and full utilization of a large number of elements, but also ensure the stability and long-term effect of trace elements. It has a good effect of enhancing plant respiration, improving plant redox process, and promoting plant metabolism. Photosynthesis and chlorophyll formation can significantly promote and activate physiological ...

Problems solved by technology

At present, most manufacturers in my country mainly sell distiller's grains directly as roughage at low prices, while a few manufacturers directly discharge wet grains, which not only causes serious environmental pollution, but also leads to waste of resources
