Embodiment 1
[0057] To prepare morel strains:
[0058] Location: Yangma Town, Jianyang City, Sichuan Province
[0059] Time: Started on May 9, 2015
[0060] A, rape stalks are crushed into 3 cm X 3 mm sized pieces;
[0061] B. Straw primary fermentation: Mix the components according to the following weight ratio: 10 parts of crushed rapeseed straw, 0.5 part of rapeseed cake, 0.05 part of urea, 4 parts of poultry and livestock dry manure, 0.3 part of lime, 0.2 part of gypsum, magnesium sulfate 0.05 part, 0.05 part of potassium sulfate; the water content of the mixture after mixing is 60%; 5 cubic meters of tunnel fermentation;
[0062] C. Secondary fermentation of straw: place the primary fermented straw obtained in step B in a shading and rain-proof place, pile it up into a cube with a volume of 24 cubic meters, and ferment for 90 days to obtain the straw fermentation substrate. Add 1 part of corn flour, 0.01 part of lime, 0.1 part of gypsum, and 0.001 part of potassium dihydrogen phosp...
Embodiment 2
[0074] To prepare morel strains:
[0075] Location: Pujiang County, Chengdu City, Sichuan Province
[0076] Time: Started on June 1, 2015
[0077] A. Crush the corn stalks into 3 cm X 3 mm pieces
[0078] B. Straw primary fermentation: Mix the components according to the following weight ratio: 10 parts of crushed corn stalks, 0.5 parts of rapeseed cake, 0.05 parts of urea, 4 parts of poultry and livestock dry manure, 0.3 parts of lime, 0.2 parts of gypsum, magnesium sulfate 0.05 part, 0.05 part of potassium sulfate; the water content of the mixture after mixing is 60%; build 5 cubic meters of conical piles for fermentation;
[0079] C. Secondary fermentation of straw: Place the primary fermented straw obtained in step B in a shading and rain-proof place, pile it up into a conical shape with a volume of 30 cubic meters, and ferment for 100 days to obtain the straw fermentation substrate. Add 1 part of corn flour, 0.01 part of lime, 0.1 part of gypsum, and 0.001 part of pota...

Abstract
The invention belongs to the field of edible mushroom strain production, and relates to a straw fermentation substrate, a morchella spp. strain medium and preparation methods of the straw fermentation substrate and the morchella spp. strain medium, in particular to methods for preparing a straw fermentation substrate by adopting fermented crop straw as a main raw material and then further preparing morchella spp. strains. According to the morchella spp. strain medium, the straw is prepared into the straw fermentation substrate after being fermented, and the medium is prepared by adopting the straw fermentation substrate as the main raw material. The straw fermentation substrate in the medium accounts for 90 wt% to 98 wt% by dry weight, preferably 90 wt%. The medium is utilized for preparing the morchella spp. strains. The straw fermentation substrate, the morchella spp. strain medium and the preparation methods of the straw fermentation substrate and the morchella spp. strain medium have the advantages that the formula and the preparation steps are simplified, the common raw materials are used, grain raw materials are avoided or reduced, grain resources are saved, and cost is reduced. A large amount of straw is consumed, waste is turned into wealth, air pollution caused by straw incineration is avoided, the parts, unconsumed by morchella spp., of the applied strains can serve as organic fertilizer, soil is improved, and nourishment can be provided for the next season.
Description
technical field [0001] The invention belongs to the field of edible fungus strain production, and relates to a straw fermentation substrate, a hickory chick strain culture substrate and a preparation method thereof, in particular to using fermented crop straw as the main raw material to prepare a straw fermentation substrate, and then further preparing hickory tripe Bacterial strain method. Background technique [0002] Morchella spp., also known as Morchella spp., belongs to the genus Morchella of the family Ascomycetes, Panmycetes, and is a rare edible fungus. Morchella has high nutritional value, is rich in essential amino acids and polysaccharides, and is expensive. Collecting wild hickory chicks has been unable to meet the needs of the hickory chick consumption market. [0003] The artificial domestication and cultivation of hickory chick was once a worldwide problem. In recent years, breakthroughs have been made in the artificial cultivation of morel mushrooms, and ...
