Abstract

The invention discloses a kind of methods that the grafting using mushroom spawn and bacteria stick improves quality xianggu yield, including (1) to prepare bacteria stick, and the primary raw material sawdust of bacteria stick and the ratio of wheat bran are 8:2, prepare lentinus edodes strain stick according to a conventional method, normal to cultivate；(2) mushroom spawn is prepared, the primary raw material sawdust of mushroom spawn and the ratio of wheat bran are 55-65:35-45, mushroom mushroom spawn is prepared according to a conventional method, the column circular pit of grafting (1) preparation bacteria stick is reserved above mushroom spawn, and the production mushroom spawn time is later than (1) and makes bacteria stick 30-35 days；(3) it grafts, when bacteria stick annesl starts fruiting, and it is grafted when mushroom spawn is just sent out full bacterium, plastic foil at bacteria stick one end and mushroom spawn round pool is removed, it will be in the vertical insertion mushroom spawn hole of bacteria stick, the mycelia of bacteria stick and mushroom spawn just links together after 3-5 days, and the nutrition of mushroom spawn and moisture pass through mycelia network transmission into bacteria stick.After the method for the present invention, 30% or more quality xianggu yield can be improved.

Description

The method for improving quality xianggu yield using the grafting of mushroom spawn and bacteria stick

Technical field

The invention belongs to technical field of edible fungi cultivation, in particular to a kind of grafting using mushroom spawn and bacteria stick improves high-quality perfume (or spice) The method of mushroom yield.

Background technique

Mushroom is one of biggish edible fungus variety of China's cultivation amount.Currently, the method for cultivating mushroom in China is typically all There is wheat bran as primary raw material using 80% sawdust and 20%, bacteria stick is made or mushroom spawn form is made with mold with polybag and is cultivated Production, does not there is always big change in decades.Sawdust is responsible for providing carbon source in the feed, and wheat bran provides nitrogen source, and the two maintains Carbon-nitrogen ratio needed for mushroom growth.The problem of being currently, there are be, nitrogen source supplier wheat bran springy texture in conventional formulation, Nutrition decomposition and rate of release are fast, and then particle is big, harder for carbon source supplier sawdust, and nutrition decomposition and rate of release are slower. Therefore, in two or three batch of fruiting early period, the C/N ratio that bacterium bag provides also is able to maintain the development institute of suitable mushroom fruiting body substantially It needs, fruiting quality is fine.However after third stubble, since carbon source surplus is still more in bacterium bag, and nitrogen source early period discharges more, the later period Surplus is less, and carbon-nitrogen ratio quickly improves, and cannot meet the normal development demand of mushroom fruiting body again, cause the quality of fruiting quick Decline, show as thallus become smaller, be thinning, easy parachute-opening phenomena such as, a large amount of substandard products mushroom output has seriously affected cultivating champignon Economic benefit.

Summary of the invention

In view of the problems of the existing technology, the object of the present invention is to provide a kind of grafting raisings using mushroom spawn and bacteria stick The method of quality xianggu yield uses mushroom stick in the method that period appropriate grafts fruiting bacteria stick and nutrition mushroom spawn From absorption in nutrition mushroom spawn and supplemented with nitrogen source needed for the later period, to meet fruiting later period fruiting bacteria stick mushroom fruiting body hair The demand to carbon-nitrogen ratio nutrition is educated, the mushroom of high-quality is produced, improves the economic benefit of Lentnus edodes.

The present invention is achieved through the following technical solutions.

A method of quality xianggu yield being improved using the grafting of mushroom spawn and bacteria stick, is included the following steps:

(1) ratio of the primary raw material sawdust and wheat bran that prepare bacteria stick bacteria stick is 8: 2, prepares lentinus edodes strain stick according to a conventional method, Normal culture；

(2) ratio of the primary raw material sawdust and wheat bran that prepare mushroom spawn mushroom spawn is 55-65: 35-45, prepares perfume (or spice) according to a conventional method Mushroom brick reserves the column circular pit of grafting (1) preparation bacteria stick above mushroom spawn, and the production mushroom spawn time is later than (1) production bacteria stick 30-35 days；

(3) grafting starts fruiting when bacteria stick annesl, and when mushroom spawn just sends out bacterium full is grafted, bacteria stick one end and mushroom spawn round pool The plastic foil at place removes, and by the vertical insertion mushroom spawn hole of bacteria stick, the mycelia of bacteria stick and mushroom spawn just links together after 3-5 days, bacterium The nutrition of brick and moisture pass through mycelia network transmission into bacteria stick.

In the present invention, mushroom spawn is equivalent to the effect of " battery ", transmits its battalion lacked to bacteria stick by mycelia network It supports, bacteria stick is responsible for fruiting.Since the bacteria stick of fruiting possesses the double nutrition of conventional cultivation bacteria stick, and can be to the carbon source of mushroom spawn It is selectively absorbed with nitrogen source, thus it is possible to produce more quality xianggus out.

Compared with prior art, the beneficial effects of the present invention are: the bacteria stick fruiting later period passes through bacterium after (1) implementation present invention Silk absorbs nutritional ingredient and moisture in mushroom spawn, and due to supplying more nitrogen and less carbon in mushroom spawn, i.e. C/N is relatively low, makes up C/N relatively high defect in bacteria stick, needed for the C/N ratio for obtaining bacteria stick has substantially met the development of mushroom fruiting body, very greatly The bacteria stick fruiting later period insufficient situation of nitrogen nutrition is improved in degree, improves fruiting quality, and quality xianggu ratio can be improved 30% More than.(2) after implementing the present invention, mushroom spawn is laid in ground, convenient to keep the skin wet to it and other management.

Specific embodiment

The method that the present invention improves quality xianggu yield using the grafting of mushroom spawn and bacteria stick, is to prepare according to a conventional method first Bacteria stick raw material, the primary raw material sawdust of bacteria stick and the ratio of wheat bran are 8:2, prepare lentinus edodes strain stick according to a conventional method, normal to cultivate； Then mushroom spawn raw material is prepared, the primary raw material sawdust of mushroom spawn and the ratio of wheat bran are 55-65: 35-45, mushroom spawn is prepared with mold, The column circular pit of grafting bacteria stick is reserved above mushroom spawn, the production mushroom spawn time is later than production bacteria stick 30-35 days；When bacteria stick annesl Start fruiting, and when mushroom spawn just sends out bacterium full, is grafted, and the plastic foil at bacteria stick one end and mushroom spawn round pool is removed, bacteria stick is stood Formula is inserted into mushroom spawn hole, and grafting is completed.The mycelia of 3-5 days bacteria sticks and mushroom spawn just links together after after grafting, the nutrition of mushroom spawn Pass through mycelia network transmission into bacteria stick with moisture, from this, gives bacteria stick moisturizing indirectly by way of keeping the skin wet to mushroom spawn, mend Water operation is simply again convenient.
