Embodiment 1

[0020] Collect the Vc fermented mash after ultrafiltration, adjust the protein weight concentration to 6-8%, take 10kg, add KOH 100g, and hydrolyze at 120°C for 20 minutes; the sample turns from turbid liquid to translucent, hydrolyze When the concentration reaches 60%, adjust the pH to 5.5-8.0 with the discarded gulonic acid mother liquor (or ion exchange), concentrate until the amino acid weight content reaches more than 10% (the present embodiment reaches 13%), and add appropriate amount of trace elements Fe, Zn, Mn , Mo, B (by weight, 0.5%≤Fe+Zn+Mn+Mo+B≤10.0%), in this embodiment: Fe 0.3%, Zn 0.15%, Mn 0.05%, Mo 0.05%, B 0.05 %; archived for future use. When applying, spray water at 1-4 liters per mu per week.

Embodiment 2-6

[0022] The difference from Example 1 is that the process parameters are different (see Table 1):

Abstract

The invention belongs to a field in which waste materials are used to produce manure, in particular to a method which utilizes Vc fermented liquor to produce amino acid manure, and by applying the method, amino acid liquor manure with low production cost and high efficiency can be produced. In the preparation process of the amino acid liquor manure, the ultrafiltered Vc fermented liquor is collected, under a certain condition, the protein in the Vc fermented liquor is hydrolyzed into amino acid by utilizing alkali, and an appropriate amount of microelements (Fe, Zn, Mn, Mo and B) is supplemented in the Vc fermented liquor, so that the amino acid liquor manure with the weight content reaching over ten percent is produced. According to actual planting circumstances, the invention can be applied in an appropriate amount by the methods, such as spraying, irrigating, etc. and can notably increase yield and effectively prevent diseases of crops.

Description

technical field [0001] The invention belongs to the field of using waste to produce fertilizer, in particular to a method for producing amino acid fertilizer by using Vc fermented mash. Background technique [0002] Amino acid liquid fertilizer is regarded as a fertilizer with great development potential because of its high nutrition. According to relevant information, plants can directly absorb amino acid molecules and their complexes in amino acid liquid fertilizer, and the fertilizer efficiency of amino acid is higher than that of the same amount of ammonia nitrogen and nitrate nitrogen. The complexation of amino acids and other inorganic salts will produce a superimposed effect on absorption, which will accelerate the absorption speed and utilization rate of other nutrients. Therefore, it can increase output and improve quality, and is favored by people, and at the same time it arouses people's enthusiasm for its in-depth development. [0003] Currently, amino acids ar...
