Abstract

The invention discloses a culture substrate for volvariella volvacea. The substrate comprises 30-50% of secondary wood flour subjected to laccase hydrolysis, 20-40% of chopped straws, 5-10% of secondary chopped straw subjected to cellulase hydrolysis, 1-5% of calcium superphosphate and 1-5% of gypsum powder. According to the culture substrate for volvariella volvacea, provided by the invention, straw wastes can be fully utilized, and the cultured volvariella volvacea is crisp and refreshing in mouthfeel.

Description

The culture medium of a kind of straw mushroom

Technical field

The invention belongs to mushroom cultivation field.

Background technology

In mushroom cultivating process, the main two problems one considered is the level of growth of mushroom itself, another is the control of miscellaneous bacteria and insect pest in mushroom cultivating process, the control of these two aspects and balance are except relying on growth conditions, as outside the regulating and control of temperature, humidity etc., also depend on the selection of culture medium, not only if culture medium is beneficial to the growth of mushroom itself but also pole is beneficial to the breeding of miscellaneous bacteria and insect, then not favourable to the cultivation of mushroom.

Summary of the invention

The object of the present invention is to provide one can both meet straw mushroom well to grow, obtain a mushroom straw mushroom that large stem stalk is little, mouthfeel is crisp and refreshing, the culture medium that can effectively suppress varied bacteria growing to be bred again.

Technical scheme of the present invention is as follows: the culture medium of a kind of straw mushroom, described matrix is considered to be worth doing by the secondary wood fragments after laccase is hydrolyzed of 30 ~ 50%, the crushing straw of 20 ~ 40%, 5% ~ 10% secondary crushing straw after cellulase hydrolysis, the calcium superphosphate of 1% ~ 5%, the terra alba composition of 1% ~ 5%.

Its preferred embodiment is: described cellulase be selected from circumscribed beta-glucanase, Endo-β-glucanase and beta-glucosidase one or more.

Cellulase herein also can select the complex class cellulase of commercial type.

Its another preferred embodiment is: described crushing straw is the crushed material of corn or wheat stalk.Its another preferred embodiment is: described wood fragments bits are the limb crushed material of fruits trees.

The trees of growth fruit that refer to of said fruits trees herein, as pear tree, Japanese plum, peach, apple tree, apricot etc.

Usefulness of the present invention is:

1) Appropriate application waste straw, is beneficial to circulation and the regeneration of resource;

2) this culture medium can grow and obtain the crisp and refreshing straw mushroom of mouthfeel;

3) this culture medium can suppress the growth of other miscellaneous bacteria and insect, obtains the straw mushroom of good quality.

Embodiment

Embodiment 1

1) by mass content be 50% secondary wood fragments bits, the mass content crushing straw that is 34%, the mass content secondary crushing straw that is 10%, mass content be 1% calcium superphosphate, mass content be 5% terra alba fully mix, adding the water after disinfection to water content is 50%, culture medium is obtained after mixing, wherein secondary crushing straw is the wheat crushing straw after cellulase hydrolysis, secondary wood fragments bits are the wood fragments bits of the apple tree after laccase hydrolysis, and described wood fragments bits, crushing straw, terra alba have carried out high-temperature sterilization process all in advance;

2) aseptically packed by culture medium and obtain pocket, inoculate straw mushroom bacterial classification in pocket after, constant temperature culture is to fruiting.

Embodiment 2

1) by mass content be 40% secondary wood fragments bits, the mass content crushing straw that is 40%, the mass content secondary crushing straw that is 10%, mass content be 5% calcium superphosphate, mass content be 5% terra alba fully mix, adding the water after disinfection to water content is 50%, culture medium is obtained after mixing, wherein secondary crushing straw is the corn crushing straw after cellulase hydrolysis, secondary wood fragments bits are the wood fragments bits of the pear tree after laccase hydrolysis, and described wood fragments bits, crushing straw, terra alba have carried out high-temperature sterilization process all in advance;
