Matrix produced by using vinegar residue for greening and production process thereof

Abstract

The invention discloses a matrix produced by using vinegar residue for greening and a production process thereof, belongs to soil for greening projects and a manufacturing method, and aims at the problems that the vinegar residue matrix in the prior art has insufficient stacked fermentation, and the vinegar residue and the mushroom residue are difficult to process in factories in batch and cannot realize commercial production. The process comprises the following steps: adding bacteria into the vinegar residue serving as a main material and plant ash serving as an auxiliary material and mixing the materials, then performing primary (aerobic) fermentation, adding 6 to 8 percent of vermiculite, 10 to 15 percent of perlite and 15 to 20 percent of mushroom residue into the mixture, and performing secondary post (corrosion) fermentation to obtain granular matrix of which the organic substance content is no less than 50 percent, the soluble ion concentration EC value is 1 to 3mS/cm, the pH is 5.5 to 6.5, the venting gap is 25 percent (V) and the water holding gap is 50 percent (V). Through trial, the matrix has loose and ventilated texture, obviously reduces the soil volume weight around flowers and plants, improves water retention, fertility retention and air permeability of the soil, has the function of improving a soil micro-zone environment around the plants, and develops an important path for avoiding environment pollution and changing waste into valuable for factory batch treatment of the vinegar residue and the mushroom residue and realization of commercial production.

Description

technical field [0001] The invention belongs to soil for greening engineering and a manufacturing method thereof, in particular to a substrate for greening produced by using vinegar grains and a production process thereof. Background technique [0002] Vinegar grains are the main by-products of vinegar making, accounting for about 70-80% of the raw materials for making vinegar. It is composed of rice husk fermented by making vinegar and a small amount of bran and rice wine dregs, but it contains 6% to 10% of crude protein, 2% to 5% of crude fat, 20% to 30% of nitrogen-free extract, crude Ash content is 13% to 17%, calcium is 0.25% to 0.45%, phosphorus is 0.16% to 0.37%, and it is rich in nutrients; however, it is a difficult-to-handle organic material with a fiber content of more than 99% and a pH of 4.5-5.5. waste. Due to its large quantity, high fiber content and high acidity, it is easy to cause environmental pollution and has become a difficult problem for the vinegar ...

Problems solved by technology

[0010] At present, in the greening construction of urban roads and greening projects in garden residential quarters, first of all, there is a common backfill soil that is mostly non-planting soil, yellow soil or deep soil, which is obviously not suitable for planting flowers and seedlings; Quicklime and fly ash, resulting in soil pH is obviously alkaline, not sui
