Problems solved by technology

[0003] As the technology of artificially planting hickory chicks has made major breakthroughs in China, such as flat shed cultivation, steel frame greenhouse cultivation, and forest cultivation, etc., are all based on field and facility cultivation models, but the existing hickory chick cultivation substrate , using a large amount of grain raw materials, such as wheat, corn, etc., not only has high cost, but also causes the consumption of grain resources, and the final output of morel mushrooms is still not ideal

Embodiment 1

[0032] A hickory chick cultivation substrate, the cultivation substrate is made of the following raw material components in parts by weight: 20 parts of semi-carbonized biomass, 20 parts of sawdust, 45 parts of humus, and 8 parts of rice straw; the semi-carbonized biomass is made of It is prepared from the following raw materials in percentage by weight: 25% distiller's grains, 8% corncobs, 65% phosphogypsum, 1% polyvinyl alcohol and 1% carboxymethyl cellulose; it also includes 25 parts of exogenous culture substrate, exogenous culture substrate It includes 20% soybean powder, 6% sucrose, 5% lime, 2% potassium dihydrogen phosphate, and the rest is water.

[0033] Semi-carbonized biomass is prepared by the following steps:

[0034] S1. Weighing 25% of distiller's grains, 8% of corncobs, 65% of phosphogypsum, 1% of polyvinyl alcohol and 1% of carboxymethyl cellulose according to weight percentage;

[0035] S2. Under anaerobic conditions, place distiller's grains and corncobs in...

Embodiment 2

[0043] A hickory chick cultivation substrate, the cultivation substrate is made of the following raw material components in parts by weight: 15 parts of semi-carbonized biomass, 25 parts of sawdust, 40 parts of humus, 5 parts of rice straw; the semi-carbonized biomass is made of It is prepared from the following raw materials in weight percentage: 35% of distiller's grains, 7% of corncobs, 55% of phosphogypsum and 3% of polyvinyl alcohol; it also includes 30 parts of exogenous culture medium, which includes 15% of soybean powder, 5% of sucrose %, lime 3%, potassium dihydrogen phosphate 1%, and the rest is water.

[0044] The preparation method of the semi-carbonized biomass is the same as that in Example 1, except that the pyrolysis rate is 5°C / min and the temperature is 300°C.

[0045] Cultivation method is the same as embodiment 1, difference is: inoculum size is 0.3kg / m 2 .

Embodiment 3

[0047]A hickory chick cultivation substrate, the cultivation substrate is made of the following raw material components in parts by weight: 18 parts of semi-carbonized biomass, 20 parts of sawdust, 45 parts of humus, 6 parts of rice straw; the semi-carbonized biomass is made of It is prepared from the following raw materials by weight percentage: 25% distiller's grains, 7% corncobs, 65% phosphogypsum and 3% polyvinyl alcohol; the pH of the cultivation medium is 6-7, and the water content is 65%; it also includes exogenous culture medium 20 parts, the exogenous culture medium includes 25% soybean powder, 8% sucrose, 3% lime, 3% potassium dihydrogen phosphate, and the rest is water.

[0048] The preparation method of the semi-carbonized biomass is the same as in Example 1, except that the pyrolysis rate is 4°C / min and the temperature is 260°C.

[0049] Cultivation method is the same as embodiment 1.

Abstract

The invention belongs to the technical field of morchella esculenta, and particularly relates to a morchella esculenta culture medium and a culture method thereof.The culture medium is prepared from, by weight, 15-20 parts of semi-carbonized biomass, 20-25 parts of wood chips, 40-45 parts of humus soil and 5-8 parts of straw; the semi-carbonized biomass is prepared from the following raw materials in percentage by weight: 20-35% of vinasse, 5-10% of corncob, 55-65% of phosphogypsum and 2-3% of an adhesive. According to the morchella culture medium, vinasse, corncobs, ardealite and an adhesive are utilized to form semi-carbonized biomass, the porosity of the culture medium is increased, fertilizer nutrients are slowly released, the utilization rate is increased, an exogenous culture medium is sprayed, morchella fruiting is stimulated, nutrition is supplemented for growth of morchella, primordium and sporocarp formation is promoted, and the morchella yield is increased. The growth cycle of the morchella esculenta is shortened; the yield is improved.

Description

technical field [0001] The invention relates to the technical field of hickory chicks, in particular to a hickory chick cultivation substrate and a cultivation method thereof. Background technique [0002] Morchella is a kind of saprophytic fungus with high nutritional and medicinal value. It is a kind of delicious edible and medicinal fungus. It has a unique smell, delicious fragrance, and a fresh, smooth, crisp and tender taste. Morchella is extremely nutritious and has the functions of resolving phlegm and relieving cough, promoting digestion and regulating qi, promoting intestinal peristalsis, invigorating the spleen and stomach, etc. It is a rare and precious Chinese herbal medicine with extremely high health care and medicinal functions. [0003] As the technology of artificially planting hickory chicks has made major breakthroughs in China, such as flat shed cultivation, steel frame greenhouse cultivation, and forest cultivation, etc., are all based on field and facil...
