Abstract

The invention provides a method for producing biological fertilizer by using marijuana degumming waste liquid. The method comprises the following steps: (1) adding the marijuana degumming waste liquid and starch which serve as indicators into a reaction container, and under an alkaline condition, dropwise adding an iodine-potassium iodide solution, and stopping adding the iodine-potassium iodide solution till reaction liquid turns into light blue; (2) adding activated carbon for adsorption, standing for 30 to 60 minutes, performing filtering, thus obtaining filtrate A, adding glucan for stirring for 1 to 2 hours, performing filtering, and removing filter residues, thus obtaining filtrate B; (3) adding the filtrate B into a fermentation tank, and then adding a microbial agent for fermentation, thus obtaining biofertilizer stoste; (4) adding beta-cyclodextrin into the biofertilizer stoste, and stirring for 2 to 4 hours, thus obtaining required biological fertilizer. According to the method, harmful substances can be removed from the degumming waste liquid, which is produced by electrochemical-enzymolysis united degumming, through chemical treatment, and gum in the degumming waste liquid is turned into the biological fertilizer easily absorbed by plants through biological fermentation.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for producing bio-fertilizer by utilizing hemp degumming waste liquid. Background technique [0002] Cannabis is an annual herb of the Moraceae family. The scientific name is cannabis Salival, and the common names are hemp, cold hemp, thread hemp, flower hemp, etc. There are about 150 varieties of hemp, which are mainly distributed in Asia and Europe. my country is the center of hemp production in Asia, and the cultivation area is Hemp production ranks first in the world, and its production areas are all over the country, but mainly in the Yellow River Basin. Tai'an in Shandong and Huating in Gansu are well-known cannabis producing areas and are the main economic crops in this area. Hemp cultivation does not have high requirements on climate and soil. It grows rapidly, has strong pest resistance, and does not require pesticides and fertilizers during the c...
