Traditional Chinese medicinal residue oyster mushroom cultivation matrix and preparation method thereof

Abstract

The invention relates to a traditional Chinese medicinal residue oyster mushroom cultivation matrix and a preparation method thereof. The cultivation matrix comprises traditional Chinese medicinal residues, biogas residues, lime powder, gypsum powder, urea, calcium superphosphate and wheat bran. The biogas residues and the traditional Chinese medicinal residues are combined, and proper auxiliary materials are supplemented to realize coarse and fine complementation of the nutrition and particles of the matrix, and normal spawn running, normal fruiting and stable output can be reached without adding other raw materials. The invention also provides the preparation of the cultivation matrix. The oyster mushroom cultivation matrix has a 80% lower cost than matrixes adopting cottonseed hull as a raw material, and has an about 60% lower cost than matrixes adopting cobs as a straw raw material, and the general biological efficiency of the traditional Chinese medicinal residue oyster mushroom cultivation matrix is about 120%.

Description

[0001] technical field [0002] The invention belongs to the technical field of using new resources to obtain the cultivation substrate of Pleurotus ostreatus, and in particular relates to a cultivation substrate of Pleurotus ostreatus with traditional Chinese medicine dregs and a preparation method thereof. [0003] Background technique [0004] Pleurotus ostreatus is the general name of the genus Pleurotus. Currently, artificial cultivation mainly includes strains such as Pleurotus pectinosa, Pleurotus purpurea, Pleurotus aeruginosa, Florida Pleurotus, abalone mushroom, and Pleurotus ferulae. It can be said that the start of the production of edible fungi and the formation of industrialization in my country mainly started with flat mushrooms. The main reason is that the production of flat mushrooms is simple and the price is popular, so that the majority of farmers quickly master the production technology and let consumers Quickly embraced edible mushrooms. Taking Shandon...

Problems solved by technology

[0006] Plant-based traditional Chinese medicine dregs have low effective nutrients and thick and long particles. When used alone as a cultivation substrate for Pleurotus ostreatus, there are many problems such as insufficient nutrition, too thick substrate, large space in the substrate, and low water holding rate of the substrate. The fruiting efficiency is low, as disclosed in Chinese Patent Document CN1918963 (Application No. 200610068623.8), the method for utilizing Chinese medicine dregs to produce edible fungus cultivation material, adopts the method of fermentation treatment for the traditional Chinese medicine dregs, so that the substrate with low nutrient content is regenerated in the fermentation process. A large amount of nutrients are lost, which makes the cultivation effect unsatisfactory, and over-ripe traditional Chinese medicine dregs are prone to contamination by fungi such as Neurospora and Trichoderma during the fermentation process, resulting in extremely unstable cultivation effects and low yields; The content of organic matter is higher, but the particles are finely divided, and there are problems such as serious poor ventilation in the substrate, long time for bacteria generation, and high pollution rate of bacteria bags when used as a flat mushroom cultivation substrate alone; as disclosed in a Chinese patent document CN101100403 (application number 200710015927.2). Culture medium of Agaricus bisporus with slag and its preparation method, 2000-4000 parts of biogas residue, 2000-5000 parts of forage, 500-2000 parts of manure powder, 40-120 parts of superphosphate, 20-60 parts of urea, 60-200 parts of lime powder 30-180 parts of gypsum powder, 30-60 parts of calcium carbonate powder
