Culture medium, culture method for culturing field-exposed auricularia auricula and mushroom stick arrangement structure

Abstract

The invention discloses a culture medium and a culture method for culturing field-exposed auricularia auricula. The culture medium comprises the following raw materials: 35-45% of mango branch sawdust, 25-35% of tea twig powder, 22.3-24.3% of weed tree sawdust, 5.5-7.5% of wheat bran, 0.05-0.15% of gypsum powder, 0.05-0.15% of hydrated lime powder. The culture method comprises: (1) manufacturing mushroom sticks: mixing raw materials of the culture medium, then adding water, stirring the raw materials with water uniformly, putting the mixture into a bag for sterilization, and performing aseptic inoculation; (2) puncturing holes in the mushroom sticks: puncturing holes by adopting a hole puncturing machine; and (3) arranging the mushroom sticks: selecting a winter fallow farmland after harvesting from the end of September to the mid October, cleaning and leveling the farmland first, spraying hydrated lime on the ground surface for sterilization, and then carrying out arrangement of the mushroom sticks. Tea twigs applied to the culture medium provided by the invention are rich in cellulose, tea polyphenols, polysaccharides, vitamins, mineral substances, proteins and the like, and mango branches are rich in carbohydrates, vitamins, microelements and the like. The culture medium provided by the invention provides necessary substances for the growth of the auricularia auricula and enables nutrients to be proportioned more balanced, so that a product has a fragrant mouthfeel, a higher yield and better quality.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, and more specifically relates to a culture medium, a cultivation method and a mushroom stick layout structure for the cultivation of cloud fungus in the open field. Background technique [0002] Cloud ear is black fungus (Auricularia auricula), also known as light fungus, is one of my country's traditional export commodities. It tastes delicious, tender, crisp and refreshing, unique in flavor, has high nutritional value and obvious health care effect, and is deeply loved by the world. The production and development of cloud fungus has gone through four stages: natural wild, log cutting, section wood inoculation, and substitute cultivation. The early commodities came from the collection of natural wild cloud fungus, and later developed into a log cutting method for production by natural inoculation; in the 1970s, relevant scientific research departments separated, purified, and cultivated...

AI Technical Summary

Problems solved by technology

[0003] The current cloud ear production mode is to put cottonseed husks, wood chips, crushed crop straw, bran, quicklime, gypsum, etc. into plastic bags, and after sterilization, inoculation, and ear stimulation, the fungus bags are hung in the shed or erected. Put them on the ground bed for ear management, but the method selection and cultivation raw materials are very important in the cultivation of cloud fungus, and the use and ratio of raw materials in cultivation, the discharge of mushroom sticks in the open field, and water spraying facilities are all significant. Affecting the output of cloud fungus, there are problems such as low yield, poor quality and high pollution rate in the medium prepared from raw materials such as cottonseed husk, sawdust, crop straw pulverization, bran, quicklime, gypsum, etc. Therefore, the method for producing cloud fungus Needs to be improved
