Embodiment 1

[0021] Example 1: Using 1,000 kg of raw materials, extruding at 150-170°C through a twin-screw extruder to obtain pellet-shaped culture material. The material of the twin-screw extruder has 10 seconds in the high-temperature pipeline to achieve the disinfection effect. Its water cooling system can reduce the temperature of the material to about 85°C. Cool under GMP conditions, make the temperature reach below 25℃, mix well with the liquid bacteria, the ratio of material to water is 100:150, fill in plastic bottle container and glass bottle container, add 0.5 kg of mixed culture material to each container, and seal . After the surface of the culture material is covered with hyphae, increase the ventilation. Manage according to known cultivation techniques. Thus, the fruit body is obtained and becomes a commodity of Coprinus comatus.

Embodiment 2

[0022] Example 2: Using 500 kg of raw materials, ammonium citrate, 0.1 kg of potassium salt, 0.05 kg of magnesium sulfate, 0.5 kg of calcium carbonate and 0.6 g of trace element selenium. After mixing, it is extruded and expanded by a twin-screw extruder to obtain a granular culture material. Cool to inoculate the temperature below 25°C. Mix well with the liquid Coprinus comatus strains, with a material-to-water ratio of 100:120. The moulding steps in the forming production process are as follows: the container enters the sleeve first, then fills the material, roll-forms, exits the groove, and caps. Add 0.5 to each container Kilogram of mixed culture material, seal, put on the shelf, cultivate, and produce Coprinus comatus.

Abstract

The invention belongs to the technical field of agriculture, in particular to the technical field of cultivation of edible and medical fungi. Production of coprinus comatus in China is industrialized in Anyuan County. Pre-treatment by the method of cooking to disinfect and sterilize in production consumes large heat energy and costs a long time. The method provided by the invention is characterized in that 1, the sterilizing technology of culture materials is different from that in the past and culture medium materials are directly subjected to flash evaporation at 150-170 DEG C to sterilize; 2, the disinfecting time of flash evaporation to sterilize only costs about 10 seconds; 3, according to the invention, the culture medium materials are cooled and inoculated with culture of flammulina velutipes after the culture medium materials are cooled; and 4, the culturing container is not needed to be sterilized at high temperature so that the production process is simplified and the production time is shortened, so as to achieve a novel culturing technology which saves energy and is in low-carbon production.

Description

Technical field: [0001] The invention belongs to the technical field of agriculture, especially the cultivation of edible and medicinal fungi. Background technique [0002] Edible medicinal fungi are closely related to human health, for example: Coprinus comatus, Tremella, Hericium, Shiitake, Cordyceps and other dozens of fungi. After years of development, Coprinus comatus has been produced in factories in my country, and the products have developed into a variety of processed products and sold at home and abroad. According to the article “Efficient Three-dimensional Circulation Cultivation Technology of Coprinus comatus” (Huang Haiyang, Guo Xiuying, Chu Fengli) introduced in Northern Horticulture 2010 (16): 188~189, the culture materials are mixed according to the ratio and put into 17cmx33cm polyethylene plastic bags. 400g bagged dry material, normal pressure sterilization for 8-10h, autoclave sterilization for 1.5-2h. In the production process, pre-treatment is required by s...
