Abstract

The invention discloses a preparation method of liquid medical fertilizer for hydroponic flowers and medical fertilizer. The preparation method comprises the following steps: (1) performing the anaerobic fermentation for human or animal excrement, collecting a fermentation solution, performing suction filtering, obtaining filtrate, concentrating the filtrate for 7 to 10 times by virtue of a reverse osmosis membrane, and obtaining a concentrated solution; (2) collecting a given amount of concentrated solution, adding nitrogen fertilizer and phosphorus fertilizer into the concentrated solution,stirring, dissolving, and obtaining a solution A; (3) adding metal element fertilizer and HEEDTA into a given amount of concentrated solution, stirring, dissolving, standing, and obtaining a solutionB; and (4) mixing the solution A and the solution B, adding the biochemical fulvic acid, uniformly stirring, finally adding ascorbic acid to adjust the PH to 6 to 6.8, and obtaining a finished productmedical fertilizer, wherein every one L of liquid medical fertilizer is configured, the addition amount of the nitrogen element is 90 to 110 g, and the addition amount of the phosphorus element is 50to 55 g. The preparation method has the advantages that the concentration of the nutrients contained in biogas slurry can be increased; and moreover, by adding the biochemical fulvic acid and the inorganic trace elements, the liquid medical fertilizer can be better absorbed by plants, and the disease resistance of the flowers can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a method for preparing liquid medicinal fertilizers for hydroponic flowers and the medicinal fertilizers. Background technique [0002] In recent years, with the continuous development of the economy and society, the problems of energy shortage and environmental pollution in our country are also intensified. Anaerobic fermentation technology can be used to solve energy and environmental problems, and has been widely used in my country, especially in rural areas. With the increase in the number and scale of anaerobic fermentation tanks, more and more attention has been paid to the treatment of their residual biogas slurry and biogas residue. [0003] Hydroponics technology is the use of modern bioengineering technology, using physical, chemical, and biological engineering methods to domesticate ordinary plants so that they can grow in water for a long...
