Method for preparing pleurotus cornucopiae cultivation material through cinnamomum longepaniculatum leaf residues

Abstract

The invention relates to a method for preparing a pleurotus cornucopiae cultivation material through cinnamomum longepaniculatum leaf residues. The method is characterized by comprising the following steps of: crushing cinnamomum longepaniculatum leaves in which camphor wood oil is extracted by distillation into cinnamomum longepaniculatum leaf residues, adding 2.8-3.2% of calcium carbonate according to the weight of the cinnamomum longepaniculatum leaves, and fully soaking the mixture in water, and adjusting the pH to 8.5; uniformly mixing 60 parts by weight of soaked cinnamomum longepaniculatum leaf residues, 28 parts by weight of cottonseed hull, 10 parts by weight of wheat bran, 1 part by weight of white sugar and 1 part by weight of gypsum powder, and adjusting the pH to 8 to obtain the cultivation material. According to the method provided by the invention, the waste cinnamomum longepaniculatum leaf residues in which the camphor wood oil is extracted by distillation are used for replacing most part of cottonseed hull to produce the pleurotus cornucopiae, therefore, the production cost and pollution rate of cultivating the pleurotus cornucopiae are greatly reduced on the condition of not affecting the yield and quality, and meanwhile, the pollution caused by incineration of the cinnamomum longepaniculatum leaf residues is reduced so as to protect the environment.

Description

technical field [0001] The invention relates to a method for producing edible fungi, in particular to a method for producing planting material for pheasanthus by distilling and extracting camphor oil from waste camphor leaf residue. Background technique [0002] Jiji mushroom, also known as Oyster mushroom, Pleurotus, etc., belongs to the phylum Fungi, Basidiomycetes, Agaricaceae, and Pleurotaceae. It was introduced to Japan by the Hebei Institute of Microbiology. It is widely sold in Japan and is used for pasta. The stress resistance and adaptability of Jiji mushroom are very strong, and the available cultivation raw materials are also very extensive, which is slightly different from the cultivation method of Pleurotus ostreatus. At present, raw materials / clinker bags are mostly used for wall-planting mushrooms. At present, the main cultivation formulas are: (1) 75% cottonseed hulls, 20% wheat bran, 2% sucrose, 1% superphosphate, 1% calcium carbonate, 1% gypsum powder; (2)...

AI Technical Summary

Problems solved by technology

However, the above two formulas all need to use a large amount of cottonseed hulls and wheat bran, resulting in higher production costs, and higher costs in non-cotton-producing areas

In fact, almost all edible fungus cultivations currently use cottonseed hulls as the main raw material (accounting for more than 60% of the cultivation materials). With the further development of my country's edible fungi industry, the contradiction between supply and demand of cottonseed hulls will further increase ( drama), the cost will continue to increase

[0003] Sichuan Yibin area is rich in camphor oil resources, with an annual output of nearly 6,000 tons of camphor oil. Calculated at an oil yield of 2%, it can produce 300,000 tons of camphor leaf residue. The camphor leaf residue after distillation and extraction of camphor oil is usually directly incinerated. , or piled up and rotted on the spot, which pollutes the environment and also causes a waste of resources
