Method for manufacturing Pleurotus citrinopileatus culture material from sunflower byproducts

Abstract

The invention relates to a Pleurotus citrinopileatus culture material which is characterized in that sunflower byproducts, including sunflower heads, sunflower straws, sunflower seed husks and sunflower seed cakes, are used as main raw materials; bran, sunflower seed cakes, calcium superphosphate, lime powder, gypsum powder and the like are used as auxiliary materials; and the water content of the culture material is 63-65%. The invention also relates to a manufacturing method of the culture material. The method has the following advantages: the raw materials are proportioned reasonably to promote the physical behavior complementation and nutrient complementation of the culture material, so that the culture material has favorable air permeability and high water retention property, and the Pleurotus citrinopileatus hypha can grow vigorously; the culture material has the advantages of balanced nutrition, good growth vigor of sporophores and high yield, and the biological efficiency is up to 140.6-148.3%; and the method provides a solution for innocent treatment of sunflower heads, sunflower straws and sunflower seed husks, and finds out a new substrate for culturing Pleurotus citrinopileatus.

Description

technical field [0001] The invention utilizes sunflower by-products-sunflower discs, sunflower stalks, sunflower seed shells and sunflower seed cakes to prepare the cultivation material of P. chinensis, including the compatibility of the cultivation materials, and the preparation method of the cultivation material, and belongs to the technical field of edible fungus cultivation. Background technique [0002] Yuhuang mushroom is also known as golden top side ear, golden top mushroom, elm yellow mushroom, etc. It is named elm yellow mushroom because it is commonly found on the dead branches of saprophytic elm trees. The artificially cultivated yellow mushrooms are covered with imbricates. The base of the cap is concave into a trumpet shape, and the edge is flat and wavy. Many caps are stacked and clustered together, like a bunch of golden flowers, with a noble and elegant shape. Yuhuang mushroom is rich in nutrients such as protein, fat, carbohydrates and various vitamins. It ...

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.
