Seeding medium made of vinasse methane-sludge and preparation method thereof

Abstract

The invention relates to a seeding medium made of vinasse methane-sludge and a preparation method thereof, not only solving the problem of environment contamination caused by vinasse methane-sludge, but also effectively utilizing vinasse methane-sludge. The seeding medium comprises fresh sludge containing 90 percent of water after methane generated from vinasse in a methane tank, accessories, ferment strain I and ferment strain II, wherein the accessories comprise grass peat, vermiculite and perlite; the ferment strain I comprises saccharomycetes, lactobacillus, high-temperature actinomycetes and bacillus; and the ferment strain II comprises photosynthetic bacteria, lactobacillus, bacillus, saccharomycetes, actinomycetes and terrestrial cyanobacteria. The preparation method comprises the following steps of preparing fresh sludge, dehydrating, adding the ferment strain I for fermentation, adding the ferment strain II for secondary fermentation, air drying, adding accessories, crushing, screening and packing. The vinasse methane-sludge contains 40 to 50 percent of organic matter and 4.3 percent of available nitrogen (N), phosphorus (P) and kalium (K). The seeding medium made of vinasse methane-sludge has better hydrophilicity, and seeding can be carried out after loading the dry seeding medium and spraying water, thus saving both labor and time.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology and products, and in particular relates to a seedling-raising substrate made by fermenting distiller's grain biogas sludge and a preparation method thereof. Background technique [0002] Studies have found that during the process of growing seedlings, the growth of roots in soilless substrates is 8 to 10 times that of growing seedlings in nutrient soil, the emergence period is 1-2 days earlier, the emergence rate is increased by 10.7-15.2%, and the plant height is increased. 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 8% or more. Therefore, more than 90% of seedling crops in countries such as Japan, South Korea, the United States, Britain, and Is...

AI Technical Summary

Problems solved by technology

The area of ​​seedling crops in my country is 15 million hectares, and the area of ​​soilless seedlings using substrates is less than 2.74%. The seedling technology is backward, which restricts the development of modern agriculture in my country

It is difficult to granulate it as raw material of organic fertilizer. Organic fertilizer manufacturers discard it. A large amount of biogas residue and sludge are piled up. The smell is suffocating, and the environmental pollution is becoming more and more serious, which greatly endangers human health.
