Method for producing biological fertilizer from lychee red wine slag

Abstract

The invention discloses a method for producing biological fertilizer from lychee red wine slag. The biological fertilizer is prepared from 55-65 parts by weight of lychee red wine slag, 5-6 parts by weight of hemp seeds, 1.3-1.6 parts by weight of solid polyethylene glycol, 4-5 parts by weight of forsterite powder, 6-7 parts by weight of salt mud, 4-5 parts by weight of potassium sulfate, 3.5-3.8parts by weight of calcium formate, 17-18 parts by weight of nano-carbon black, 35-36 parts by weight of domestic organic wastes, 14-15 parts by weight of slaughterhouse abandoned pig bone, 1-2 partsby weight of nitrogen-fixing bacteria, 1-2 parts by weight of potassium-dissolving bacteria, 20-22 parts by weight of slaughterhouse abandoned cattle bone, 2.8-3.2 parts by weight of citric acid and an appropriate amount of water. The method reduces the discharge of the wastes in brewing, improves the organic content of the planting soil and conforms to the sustainable development concept of the green cycle in agricultural production.

Description

technical field [0001] The invention relates to a method for reusing wine dregs, in particular to a method for producing biological fertilizer from lychee dried red wine dregs. Background technique [0002] The use of fertilizers plays a key role in the production and quality of grapes and lychees, but there are many defects in the commercially available lychee fertilizers: first, there is no specific nutritional requirement for lychees and soil nutritional characteristics Targeting is simply to provide a large amount of nutrients such as nitrogen and phosphorus; second, chemical fertilizers are mostly used as the main supplement, organic fertilizers are supplemented, which easily produces chemical residues and pollute the environment; third, it cannot improve the soil, and in the long run It will lead to barren soil, which is not suitable for planting; Fourth, the utilization rate of fertilizers is low, which leads to excessive waste of available resources when resources ca...

[0002] The use of fertilizers plays a key role in the production and quality of grapes and lychees, but there are many defects in the commercially available lychee fertilizers: first, there is no specific nutritional requirement for lychees and soil nutritional characteristics Targeting is simply to provide a large amount of nutrients such as nitrogen and phosphorus; second, chemical fertilizers are mostly used as the main supplement, organic fertilizers are supplemented, which easily produces chemical residues and pollute the environment; third, it cannot improve the soil, and in the long run It will lead to poor soil, which is not suitable for planting; Fourth, the utilization rate of fertilizers is low, which also leads to excessive waste of available resources when resources cannot be reused.

[0003] Litchi and grapes will produce a lot of wine residue in the process of brewing dry red, and random discharge will lead to environmental pollution
