Edible fungi industrial cultivation substrate prepared from coconut bran and its application

Abstract

The invention discloses a domestic fungus industrial cultivation matrix prepared by coconut husk, and an application thereof. The cultivation matrix comprises, by mass, 5-10 parts of coconut husk, 30-40 parts of corncob, 30-40 parts of rice bran, 5-10 parts of wheat bran, 3-5 parts of corn flour, 5-10 parts of brewer's grains, 5-10 parts of soybean hull and 1-3 parts of shell powder. The water content of the cultivation matrix is 66-68%, and the pH value of the cultivation matrix is 6.2-6.8. The cultivation matrix can be applied in industrial cultivation of domestic fungi. The domestic fungus cultivation matrix prepared in the invention has the advantages of good water retention, permeability and other physical and chemical indexes, low cost, convenience for industrial operation, reduction of the safety risk of foods, realization of high output and good regularity of domestic fungi cultivated by using the matrix, and improvement of the appearance of commodities of the domestic fungi, can be applied in the industrial large-area popularization of the domestic fungi, and has substantial economic, social and ecologic benefits.

Description

technical field [0001] The invention belongs to the technical field of industrialized cultivation of edible fungi, in particular to an industrialized cultivation substrate of edible fungi prepared from coconut bran and application thereof. Background technique [0002] Coconut bran is a pure natural organic medium that falls off during the processing of coconut shell fibers, and is a by-product or waste of coconut after processing. Coconut bran has the characteristics of good water retention, air permeability, low nutrient content and slow decomposition. In recent years, it has been widely used as an ideal substrate for soilless cultivation in the facility cultivation of fruits and vegetables. [0003] The water content of the fruiting bodies of artificially cultivated edible fungi is relatively high, and the water content of the fruiting bodies of general edible fungi such as Flammulina velutipes, Pleurotus eryngii, and seafood mushrooms exceeds 80%. Longer and prolonged c...

Problems solved by technology

With the development of industrialization of edible fungi, the prices of various raw materials such as rice bran, corncobs, and bran continue to rise. Sawdust needs to be watered for a long time to remove tannins and other substances before use. Not only the water content cannot be accurately controlled, Moreover, the waste water produced during the water showering process will have a negative impact on the environment.

Cottonseed hulls widely used in traditional edible fungus cultivation have the risk of enriching pesticides and heavy metals. Beet pulp, which is mainly used as a water-absorbing material, has a high price and low quantity due to the current reduction in domestic sugar beet production and the demand for feed processing. The above factors are seriously restricted. The development of industrialization of edible fungi
