Black fungus culture compatible product and preparation method of culture

Abstract

The invention provides a black fungus culture. The culture is characterized by taking chestnut branch scraps, bud hull scraps and chestnut hull scraps as main raw materials and bran, corn powder, gypsum powder and the like as auxiliary materials, wherein the water content of the culture is 63-65%. The invention also provides a preparation method of the culture. Compared with sawdust cultures, the culture has the advantages that I. the culture is reasonable in thickness matching, so that fungi have good air permeability, the black fungus hyphae grow vigorously and the bag filling time is shortened; II. through sunlight exposure, accumulation aging and biological fermentation, not only are toxic antibacterial materials removed but also macromolecular substances are degraded, thus being favourable for absorption by black fungus hyphae; III. the black fungi have good yield properties, good merchandise properties and higher biological efficiency; and IV. the culture raw material channel is widened, thus greatly reducing the production cost.

Description

technical field [0001] The content of the invention includes the compatibility of black fungus cultivation material and the preparation method of the cultivation material, belonging to the technical field of edible fungus cultivation. Background technique [0002] The chestnut tree is a nut plant of the Fagaceae Chestnut genus, and its fruit is a famous traditional agricultural and sideline product in my country. China is the largest producer of chestnuts. According to statistics from the Food and Agriculture Organization of the United Nations (FAO), by the end of 2009, China's chestnut cultivation area was 200,000 ha 2 , the total output is about 1.09 million tons, accounting for about 77% of the world's total output. [0003] During the production and processing of chestnuts, three types of wastes are generated. One is the branches produced after pruning. my country's chestnut planting area is large, and the branches pruned from chestnut orchards can reach 700,000 tons ...

AI Technical Summary

Problems solved by technology

my country's chestnut planting area is large, and the branches pruned from chestnut orchards can reach 700,000 tons every year. However, these branches have not been rationally utilized, and most of them are used as firewood; Chestnut pods and chestnut cattail shells are the waste left after harvesting chestnuts. Generally, every 100kg of chestnuts means 60kg-90kg of dry bract shells. These bract shells are easy to obtain and the quantity is huge, but only a few are used as fuel. Outside, all the other are often discarded at will or allowed to rot; the 3rd, chestnut shell, is the pericarp of chestnut nut and is the seed coat, accounts for 10% of chestnut fruit weight, and chestnut shell is produced in the chestnut processing process, and resource is abundant and concentrated, but Most enterprises treat it as waste, which not only increases production costs, but also wastes resources
