Problems solved by technology

However, due to the inconvenience of liquid transportation, so many liquids can only be used around the sugar factory, and it is difficult to transport them to distant places.
[0011] To sum up, there is currently no mature treatment method for molasses alcohol fermentation waste liquid, and the methods are far from each other, so it is difficult to replace them.

Embodiment 1

[0033] The preparation of embodiment 1 fermentation bacterial agent

[0034] The strains used in this example are all listed in the public strain catalog of China General Microorganism Strain Collection and Management Center (Beijing), and can be purchased. The catalog numbers of each microorganism and its strains in the China Common Microorganism Culture Collection and Management Center are: Cellulomonas flavigena (No. 1.1002), Lactobacillus casei (No. 1.62), Vineland Azotobacter vinelandii (No. 1.1649), Rhizobium leguminosarum (No. 1.888), Aspergillus niger (No. 3.6193), Aspergillus oryzae (No. 3.481), Humicola insolens (Humicola insolens) (No. 3.4393), and Rhizopus oligosporus var. tuberosus (No. 3.1145). The above 8 strains were entrusted to Guangxi Yiduoshou Biotechnology Co., Ltd. through commercial channels to carry out liquid culture respectively according to the conventional strain culture method, and after centrifugation, the cells were preserved at 4°C and delivere...

Embodiment 2

[0038] The fermentation of embodiment 2 fulvic acid fertilizers

[0039] Pass the molasses alcohol fermentation waste liquid discharged from the sugar factory into the sedimentation tank, add NaOH solid to adjust the pH to 5.8, let it stand for 2 hours, and take the supernatant and sediment separately for use. Get 700kg cow dung and 300kg after pulverizing the sugarcane residue and 1kg embodiment 1 preparation of sugarcane residue and 1kg embodiment 1 and mix (do not add fermentation bacterium in the production of contrast fertilizer), then pass into above-mentioned stand-by supernatant 500L ( about 500kg), stirred evenly, piled into the fermenter and left to stand for 3 days, then added 300kg of sediment, and continued to stand for 12 days. During the standing period, the compost heap will naturally heat up. Measure the temperature inside the compost heap. When it exceeds 60°C, stir the compost heap to ventilate and cool down the compost heap. Stop stirring when the compost h...

Abstract

The present invention provides a preparation method of a fulvic acid fertilizer, and the method utilizes of molasses alcohol fermentation waste as a raw material for production. In addition, the present invention also provides the fertilizer obtained by the production method and the fermenting agent used, etc.

Description

technical field [0001] The invention belongs to the field of fertilizers. Specifically, the invention relates to a method for producing fulvic acid fertilizers, in particular to producing humic acid fertilizers by using molasses alcohol fermentation waste liquid as a raw material. In addition, the present invention also provides the fertilizer obtained by the production method and the reagents used therein. Background technique [0002] In soil science, humic acid is a mixture of complex and heterogeneous hydroxybenzenecarboxylic acids. It can be divided into three categories according to the color and solubility properties. Among them, the humic acid is soluble in acid, alkali and water and has a yellow solution. It is called fulvic acid; insoluble in water and acid, but soluble in alkali and ethanol, and the brown solution is called brown humic acid; neither soluble in acid, nor soluble in ethanol or acetone, but soluble in alkaline solution And the black solution is call...
