Embodiment 1

[0037] Embodiment 1, the method utilizing Vitex shavings to cultivate Auricularia auricula, the Auricularia auricula strain is purchased in the market

[0038] A. Preparation of liquid strains

[0039] First-class liquid culture medium formula: 20% potato, 3% bran, 2% glucose, KH 2 PO 4 0.3%, MgSO 4 0.15%, VB 1 10mg / L, CMC 0.3%, natural pH;

[0040] Secondary liquid culture medium formula: Vitex powder 5%, potato 20%, bran 3%, glucose 2%, KH 2 PO 4 0.3%, MgSO 4 0.15%, VB 1 10mg / L, CMC 0.3%, natural pH; among them, Vitex twigs are crushed and sieved through an 80-mesh sieve to obtain a powder, boiled with potatoes and bran for 30 minutes, filtered to remove slag to obtain an extract.

[0041] Use a 500mL Erlenmeyer flask with a liquid volume of 200mL for the preparation of the first-level liquid strains. After autoclaving at 121°C for 30 minutes, insert commercially available PDA slant strains under aseptic conditions, and the inoculation volume of each bottle is 4 piec...

Abstract

The invention provides a method for cultivating auricularia polytricha through thorn scraps. The method for cultivating auricularia polytricha through the thorn scraps is characterized in that the cultivation media of auricularia polytricha comprise, by weight, 60% of thorn scraps, 20% of cotton seed hull, 19% of bran and 1% of quick lime; the preparation method comprises the steps that thorns are crushed to be in a wood dust shape and are mixed with the bran and the quick lime, and the ratio between the materials and water is 1:1.4. A matched technology for cultivating the auricularia polytricha by using the thorn scraps as a main material further comprises the steps that the thorn scraps are also used as a substrate for induction in the liquid spawn culture media and grain spawn culture media and are added in advance. According to the method, the forestry waste of the thorns is fully utilized, a recycling economy mode is formed, resource waste is avoided, the cultivation cost is lowered, the yield is high, and the period is short. The method has obvious economic benefits and ecological benefits, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a fungus compost containing vitex chips and a method for cultivating the fungus. Background technique [0002] Auricularia polytricha (Auricularia polytricha) belongs to Fungiphylum, Basidiomycotina, Heterobasidiomycetes, Auricularia, Auriculariaceae, Auricularia genus in systematic classification, and belongs to different species with black fungus. Auricularia auricula is a kind of fungus with both food and medicine. Its texture is thicker and harder than black fungus, but it is chewy, crisp, thick, and large in shape. It is called "jellyfish skin" on trees and has become increasingly popular. The fungus is rich in nutrition, containing more carbohydrates, protein, fat, cellulose and multivitamins, as well as a small amount of trace elements such as iron, calcium and phosphorus. Auricularia auricula has high medicinal value. It can strengthen the b...
