Method for producing biological fertilizer by dried longan-containing red wine residues

Abstract

The invention discloses a method for producing biological fertilizer by dried longan-containing red wine residues. The biological fertilizer is prepared from 55-65 parts by weight of dried longan-containing red wine residues, 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 salty mud, 4-5 parts by weight of potassium sulfate, 3.5-3.8 parts by weight of calcium formate, 17-18 parts by weight of nano-activated carbon, 14-15 parts by weight of slaughterhouse abandoned pig bone, 1-2 parts by weight of nitrogen-fixing bacteria, 1-2 parts by weight of potassium bacteria, 1-2 parts by weight of lactic acid bacteria, 20-22 parts by weight of slaughterhouse abandoned cattle bone and an appropriate amount of water. The biologicalfertilizer reduces the discharge of wastes in the brewing process, improves the organic content of the planting soil and satisfies the sustainable development concept of green circulation in the 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 longan dry red wine dregs. Background technique [0002] The use of fertilizers in the planting process of grapes and longan plays a key role in their yield and quality, but there are many defects in the dry red longan fertilizer currently available in the market: First, there is no specific nutritional requirement for dry red longan 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 was...

[0002] The use of fertilizers in the planting process of grapes and longan plays a key role in their yield and quality, but there are many defects in the dry red longan fertilizer currently available in the market: First, there is no specific nutritional requirement for dry red longan 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] Longan and grapes will produce a lot of wine residue in the process of brewing dry red, and the random discharge will cause environmental pollution
