Method for preparing russula cultivation material by utilizing sunflower by-products

Abstract

The invention relates to a russula cultivation material, and is characterized in that the russula cultivation material takes sunflower by-products of sunflower plates, sunflower stalks, sunflower seed shells and sunflower seed cakes as main raw materials and is supplemented with bran coat, a lime powder, a gypsum powder, calcium superphosphate and other auxiliary materials, and the moisture content of the cultivation material is 63%-65%. The invention also provides a preparing method of the cultivation material. The russula cultivation material has the advantages that: one, the cultivation material has reasonable cooperation of fineness and thickness, good mushroom material permeability and strong water holding capacity, and russula mycelia are thick white and robust and have vigorous growth; two, the cultivation material has balanced nutrition, the russula has good growth vigor and high yield, and the biological efficiency is up to 130.2%-142.5%; and three, the cultivation material not only provides a solution method for harmless treatment of the sunflower plates, the sunflower stalks and the sunflower seed shells, but also finds a new matrix for russula cultivation.

Description

technical field [0001] The invention uses sunflower by-products-sunflower discs, sunflower stalks, sunflower seed shells and sunflower seed cakes to make russula cultivation materials, including the compatibility of the cultivation materials and the preparation method of the cultivation materials, and belongs to the technical field of edible fungus cultivation. Background technique [0002] Russula, also known as Russula, belongs to the Phylum Fungi, Russulales, Russulaceae, and Russula. Its fruiting body is pink, rich in amino acids, mushroom polysaccharides, a variety of mineral elements necessary for the human body, and also contains a variety of fatty acids, sterols and other functional ingredients closely related to human health, and has a certain effect on many digestive tract diseases. Russula is a precious medicinal and edible fungus. [0003] Russula is a high-temperature fungus and is an important edible fungus cultivated in summer. For a long time, mushroom farm...

AI Technical Summary

Problems solved by technology

[0006] The output of sunflower flower discs is equivalent to about 50% of the seed production. China produces about 1 million tons of sunflower discs every year. At present, there are three types of utilization methods: fermentation to produce biogas, return to the field and feed treatment, but most of them are still incinerated, causing Great waste of resources; sunflower shell production is approximately equivalent to 35% of seed production, about 700,000 tons per year. Most processing companies treat these sunflower shells as waste, which not only increases production costs, but also pollutes the environment; Sunflower stalks are upright, thick, and have high biomass. For a long time, a large number of sunflower stalks have been burned in the fields. The burning of straws not only seriously pollutes the environment, but also brings safety hazards to traffic and civil aviation.
