Description

A kind ofly utilize Chinese silvergrass as Xingbao mushroom medium of matrix and preparation method thereof

Technical field

The present invention relates to a kind of Xingbao mushroom medium and preparation method thereof, especially relate to and a kind ofly utilize Chinese silvergrass as Xingbao mushroom medium of matrix and preparation method thereof.

Background technology

Xingbao mushroom ( pleurotus eryngii), having another name called eryngo and pick up the ears, it is subject to consumer's favor deeply with good mouthfeel and longer shelf life.In recent years, the factory culture of this rare edible mushroom at home and abroad receives much concern.Research practice shows, the industrialized cultivation medium of Xingbao mushroom has direct impact to its output, quality and production cost etc., and therefore, selecting appropriate culture medium is the basis that Pleurotus eryngii industrial cultivation obtains more efficient benefit.

At present, it is main carbon source that the industrialized cultivation medium of Xingbao mushroom be take wood chip, cotton seed hulls, corncob etc., and wheat bran, rice bran, corn flour etc. are main nitrogen, and production cost is higher.

Summary of the invention

Technical problem to be solved by this invention is, provide a kind of production cost low utilize Chinese silvergrass as Xingbao mushroom medium of matrix and preparation method thereof.

The technical solution adopted for the present invention to solve the technical problems:

The present invention utilizes Chinese silvergrass as the Xingbao mushroom medium of matrix, comprises the component of following quality per distribution ratio: dregs of beans 3-8%, corn flour 5-9%, wheat bran 3-9%, Chinese silvergrass 72-82%, precipitated calcium carbonate 1.8-2.2%, lime 0.8-1.2%.

Further, dregs of beans 4-6%, corn flour 6-8%, wheat bran 4-7%, Chinese silvergrass 75-80%, precipitated calcium carbonate 1.8-2.2%, lime 0.8-1.2%.

Further, described Chinese silvergrass is Caulis Miscanthis floriduli, Nan Di, the assorted awns in Hunan No. 1, the assorted awns of the assorted awns in Hunan No. 2 or Hunan No. 3.

The present invention utilizes Chinese silvergrass as the preparation method of the Xingbao mushroom medium of matrix, comprises the following steps:

(1) pre-treatment of Chinese silvergrass: collect Chinese silvergrass stem stalk and blade, be dried to after water content < 10wt%, be crushed to 0.5 centimetre of particle diameter <; Or undried is directly crushed to 0.5 centimetre of particle diameter <;

(2) according to quality per distribution ratio dregs of beans 3-8%, corn flour 5-9%, wheat bran 3-9%, Chinese silvergrass 72-82%, precipitated calcium carbonate 1.8-2.2%, lime 0.8-1.2% takes each component, mixes.

By the spice pack according to a conventional method of gained medium, sterilizing, inoculation, after inoculation, in 20-26 ℃ of culturing room, send out bacterium and cultivate, after mycelia is covered with pocket, then through ripe cultivation in 29-32 days, enter management of producing mushroom.

Chinese silvergrass ( miscanthus) be the general designation of various awns platymisciums, containing having an appointment 15 to 20 species, belong to grass family.Assorted No. 1, No. 2, No. 3 three kinds of awns in Hunan that Agricultural University Of Hunan cultivates awns and southern reed artificial hybridization, its dry matter production per mu yield reaches 2500 kilograms, plant height can reach 4 meters, individual plant tiller number reaches more than 100, cellulose and hemicellulose reach 75%, total ash is below 5%, and annidation is strong, can vegetative propagation; Plant and can gather in for many years for 1 time, the assorted awns in Hunan No. 1, the assorted awns of the assorted awns in Hunan No. 2 and Hunan all reached high term No. 3, and maintain more than 5 years after 2 years.

Research shows, Chinese silvergrass has unique biological property, very high to luminous energy, moisture, N element availability, growth is fast, damage by disease and insect seldom, without using agricultural chemicals and chemical fertilizer, cheap, cellulose and hemicellulose level can meet the growth needs of Xingbao mushroom up to more than 80%, are to produce the organic or good host material of nuisanceless Xingbao mushroom.Use the present invention containing the Xingbao mushroom medium Xinbao mushroom culturing of Chinese silvergrass, Chinese silvergrass biological transformation ratio wherein can reach more than 80%, can improve Xingbao mushroom product yield and quality, reduces production costs.

Embodiment

Below in conjunction with embodiment, the invention will be further described.

embodiment 1

The present embodiment utilize Chinese silvergrass as the Xingbao mushroom medium of matrix, comprise the component of following quality per distribution ratio: dregs of beans 5%, corn flour 8%, wheat bran 5%, Chinese silvergrass 79%(kind is the assorted awns in Hunan No. 1), precipitated calcium carbonate 2%, lime 1%.

Preparation method, comprises the following steps:

(1) pre-treatment of Chinese silvergrass: collect Chinese silvergrass stem stalk and blade, be dried to after water content < 10wt%, be crushed to 0.5 centimetre of particle diameter <;
