Abstract

The invention relates to a cotton seedling substrate prepared from vinasse biogas residue and a preparation method thereof. The cotton seedling substrate comprises 7-9 cubes of vinasse biogas residue and 1-3 cubes of vermiculite, wherein the vinasse biogas residue is fresh mire which is generated after the vinasse is fermented in a biomass tank and biogas is generated, and the vermiculite is of clay mineral. The preparation method comprises the following steps of: sun-drying and dehydrating the vinasse biogas residue, carrying out first fermentation and secondary heterofermentation, air-drying leavening, mixing the leavening with the vermiculite, and then sieving to obtain the cotton seedling substrate. According to the invention, the problem that the vinasse biogas residue pollutes environments is solved, the vinasse biogas residue is used as the raw material of the seedling substrate, and the industrial chain of the circular economy for food processing is prolonged; the cost of the cotton seedling substrate per cubic meter is RMB 135 yuan; the cost of turf substrate raw material per cubic meter is RMB272 yuan; and therefore, the cost is reduced by more than 50%. The cotton seedling substrate has the following physicochemical indexes of: the grain sizes of 1-5mm of larger than or equal to 40%, organic matters with volume-weight of above 4.47 of 0.15-0.40g/m<3>, the total void of 60-70%, the pH value of 5.5-8.0, the conductivity of less than or equal to 80% us/cm, the total nutrient of 4.0%, and the moisture of less than or equal to 30% and reaches the optimal range of growth of seedling root systems.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology and product technology, and in particular relates to a cotton seedling-raising substrate made from distiller's grain biogas sludge (biogas residue) and a preparation method thereof. Background technique [0002] The study found that during the cotton seedling raising process, the growth of the root system in the soilless substrate was 8 to 10 times that in the nutrient soil seedling growth, the emergence period was 1-2 days earlier, the emergence rate increased by 10.7-15.2%, and the plant height increased by 13.4% %, the stem diameter increased by 21.9%, the leaf size increased by 17.4%, the transplanting shortened the seedling return period, the flowering was 7-8 days earlier, the maturity was 5-7 days earlier, the yield increased by 8-10%, the quality improved, and the income per mu increased by 8 %above. [0003] Cotton in my country has developed from direct seeding of dry seeds, di...
