Embodiment 1
[0040] preparation:
[0041] Time: May 4, 2015
[0042] Location: In the Provincial Academy of Agricultural Sciences, Jinjiang District, Chengdu City, Sichuan Province
[0043] step:
[0044] 1) The straw comes from corn, and the straw is crushed into crumbs, and the size of the crumbs is -40 mesh.
[0045] 2) Mix straw crumbs and wheat bran at a weight ratio of 10:1.
[0046] 3) The solid matter obtained in the previous step is mixed with the liquid culture of Chryseobacterium HT2 at a volume ratio of 1:2, and the effective number of viable bacteria in the liquid culture is 5.2 million per milliliter. This solid-liquid mixture is placed in a square cylinder with a volume of 2 cubic meters and soaked for 1 day.
[0047] 4) Filter out the solids. The remaining liquid culture can be used repeatedly for soaking. Add 5% quicklime by weight and 10% corn flour to the soaked solids, mix well, pack tightly into polypropylene bags, 0.4 kg per bag, and sterilize at 121°C for 2 hou...

[0057] preparation:
[0058] Time: May 4, 2015
[0059] Location: In the strain factory of the Demonstration Base of the Provincial Academy of Agricultural Sciences, Xindu District, Chengdu City, Sichuan Province
[0060] step:
[0061] 1) The straw comes from rapeseed, and the straw is crushed into crumbs, and the size of the crumbs is -40 mesh.
[0062] 2) Mix straw crumbs and wheat bran at a weight ratio of 10:1.
[0063] 3) The solid matter obtained in the previous step is mixed with the liquid culture of Chryseobacterium HT2 at a volume ratio of 1:2, and the effective number of viable bacteria in the liquid culture is 5.5 million per milliliter. The solid-liquid mixture is placed in a pool of 5m*3m*0.5m and soaked for 1 day.
[0064] 4) The solids are filtered out, and the remaining liquid culture can be used repeatedly for soaking. Add 5% quicklime by weight and 10% corn flour to the soaked solids, mix well, pack tightly into polyethylene bags, 0.6 kg per bag, and s...

Abstract
The invention belongs to the field of cultivation of morchella esculenta, and relates to a nutritional bag prepared by crop wastes needed in a morchella esculenta cultivation process and a preparation method thereof, in particular to a morchella esculenta nutritional bag prepared by straw fermenting substrates and a preparation method thereof. The preparation method comprises the following steps of (1) crushing straw; (2) mixing straw chips and wheat bran; (3) mixing a solid mixture in the step (2) and a liquid culture matter of chryseobacterium HT2, and soaking in an opening container; (4) filtering to obtain the straw chips and wheat bran, adding 3 to 5% of quicklime, and 5 to 10% of corn meal, mixing to obtain a mixture, bagging, and sterilizing, so as to obtain the nutritional bag. The preparation method has the advantages that the preparation raw materials of the nutritional bag are changed, the straw is used as the main raw material, the traditional wheat grains are replaced, the agricultural wastes are utilized, the straw is fermented and decomposed by the chryseobacterium HT2, and one part of cellulose and hemicellulose in the straw is converted into saccharides which can be easily utilized by the morchella esculenta; the cost is reduced, the pollution is reduced, and the yield of morchella esculenta is improved.
Description
technical field [0001] The invention belongs to the field of hickory chick cultivation, and relates to a nutrition bag for hickory chick cultured by using agricultural wastes and a preparation method thereof, in particular to a hickory chick nutrition bag made of straw fermentation substrate and a preparation method thereof . 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 technology of morels, and a method of supplementing organic nutrients to the soil in the c...
