The substratum of apricot spore mushroom and preparation method
Technical field
The invention belongs to the fungus growing technique field, particularly relate to a kind of substratum and preparation method of apricot spore mushroom.
Background technology
Prior art is often selected cotton seed hulls for use, and corn cob, wheat bran, wood chip, starting material such as lime are mixed with the nutrition source of solid medium as the apricot spore mushroom growth.Disclose a kind of substratum of apricot spore mushroom as " Hebei agricultural science and technology ", the prescription and the weight proportion of its raw material are as follows: cotton seed hulls 46%, weed tree sawdust 35%, wheat bran 15%, Semen Maydis powder 2%, lime carbonate 1%, sugar 1%." extraordinary economic animals and plants " disclose a kind of substratum of apricot spore mushroom for another example, and the prescription and the weight proportion of its raw material are as follows: cotton seed hulls 2000kg, wheat bran 400kg, Semen Maydis powder 50kg, brown sugar 20kg, calcium superphosphate 4kg, urea 4kg, unslaked lime 25kg.The ratio of two kinds of prescription cotton seed hullss is bigger, and because of being with velveteen on the cotton seed hulls, mechanical type stirs bottling machine bottling difficulty, the quality of influence bottling.It is unreasonable that overall in addition prescription also exists nutritive props, is unfavorable for the growth of apricot spore mushroom.
The preparation method of prior art substratum is that starting material are passed through grinding and processing simply, and granularity is bigger, adds water then and mixes stirring, substratum mixes uneven, and the bottling difficulty, and nutrition is unbalanced, it is irregular to grow, and causes prolong degradation problem under the quality collection period.
Summary of the invention
The objective of the invention is to be to overcome above-mentioned the deficiencies in the prior art, a kind of substratum of apricot spore mushroom is provided, the starting material source is abundant, cheap, and is nutritious reasonable, helps the apricot spore mushroom growth.
Another object of the present invention also is to provide a kind of preparation method of this apricot spore mushroom substratum.
The objective of the invention is to realize in the following manner: a kind of substratum of apricot spore mushroom, make by the following weight parts proportion raw material: 26~32 parts of corn cobs, 5~11 parts in rice bran, 18~22 parts in wheat bran, 18~22 parts of wood chips, 15~19 parts of residue from beans after makings, 4~6 parts of brewer's grains, 0.5~1.5 part in shellfish fossil.
The weight part proportioning of each raw material of screening formulation of the present invention is: 28~30 parts of corn cobs, 7~9 parts in rice bran, 19~21 parts in wheat bran, 19~21 parts of wood chips, 16~18 parts of residue from beans after makings, 4.5~5.5 parts of brewer's grains, 0.8~1.2 part in shellfish fossil.
The weight part proportioning of each raw material of optimum formula of the present invention is: 29 parts of corn cobs, 8 parts in rice bran, 20 parts in wheat bran, 20 parts of wood chips, 17 parts of residue from beans after makings, 5 parts of brewer's grains, 1 part in shellfish fossil.
The medium preparation method of apricot spore mushroom of the present invention in turn includes the following steps:
(a) earlier culture medium raw material is ground into particle, granularity will be below 4mm; (b) in proportion corn cob, wood pellet are added water and stirred 12~18 minutes, to the culture material water content be 40~45%, restir 28~32 minutes; (c) add rice bran, wheat bran, residue from beans after making, brewer's grains, shellfish fossil more in proportion in the compound of step (b), stirred 28~32 minutes, adding water to the culture material water content is 65~68%, restir 15~30 minutes; (d) pack into plantation bottle of the substratum compound that step (c) is stirred.
The substratum of apricot spore mushroom of the present invention has following advantage: the first, and these starting material: corn cob, wheat bran, rice bran, residue from beans after making, brewer's grains all are the waste materials of agriculture production, scientifically utilize the waste material of agricultural, promote the circulation of agricultural resource.The second, these starting material sources are abundant, cheap.The 3rd, utilize these starting material of microbiological degradation, the pollution that causes is few, has also reduced the pollution of waste material simultaneously.The 4th, contain a large amount of mycoprotein through the culture material after the microbiological degradation utilization, can be used as animal-feed and use.The 5th, these substratum can provide abundant nutrition for Pleurotus eryngii, and wherein shellfish fossil of Jia Ruing and brewer's grains can be regulated the pH value of substratum, and the interpolation of residue from beans after making can improve water content greatly, the growing environment that provides for Pleurotus eryngii; Integrate the purpose that can reach increasing both production and income.
The preparation method of the substratum of apricot spore mushroom of the present invention has following advantage: be with starting material grinding and processing granularity below 4mm, granularity is less, add water then and mix stirring, substratum mixes, bottling easily, and is balanced in nutrition, and it is neat to help the apricot spore mushroom growth, shorten collection period, and quality improves.
Embodiment
Embodiment 1: take by weighing raw material by following part by weight: 29 parts of corn cobs, 8 parts in rice bran, 20 parts in wheat bran, 20 parts of wood chips, 17 parts of residue from beans after makings, 5 parts of brewer's grains, 1 part in shellfish fossil.(a) earlier culture medium raw material is ground into particle, granularity will be below 4mm; (b) in proportion corn cob, wood pellet are added water and stirred 15 minutes, to the culture material water content be 42%, restir 30 minutes; (c) add rice bran, wheat bran, residue from beans after making, brewer's grains, shellfish fossil more in proportion in the compound of step (b), stirred 30 minutes, adding water to the culture material water content is 66%, restir 20 minutes; (d) pack into plantation bottle of the substratum compound that step (c) is stirred.
