Needle mushroom cultivation matrix formula and its preparation method

[0015] Example 1

[0016] A formula of Flammulina velutipes cultivation substrate, prepared from the following components in weight (kg):

[0017] Modified hulling 35, camellia seed shell 34, vinegar lees 12, bean cake 8, pine scale 8, cotton seed shell 25, potassium dihydrogen phosphate 3, zeolite powder 2, modified plant ash 14, nutrient soil 4,

[0018] Preparation:

[0019] (1) Modification of plant ash, the specific operations are as follows:

[0020] Add the plant ash to the high-speed stirring vessel, add 2-3% attapulgite by weight of plant ash, 1-2% silane coupling agent KH570, 1-2% vermiculite powder, 2-4% wheat bran, 0.1-0.5% tea Saponin, 1-2% flour, 0.01-0.02% vitamin A, 10-15% clay, appropriate amount of water, fully stirred at 850-890rpm for 3-5 hours, granulate, dry, and then ;

[0021] (2) Preparation of nutrient soil

[0022] The nutrient soil is prepared by the following components: magnesium sulfate 19, manganese sulfate 10, zinc sulfate 4.0, copper sulfate 1.6, ferrous sulfate 50, boric acid 0.3, vitamin A 0.02, vitamin C 0.2, vitamin D 0.01, seaweed Sodium powder 4, diatomaceous earth 45, first dissolve micro-fertilizers and vitamins in water, and then mix them with other components to form a moist nutrient soil with a water content of 20-30%;

[0023] (3) The modification method of hulling is:

[0024] Dry the hulled hulls, then pour it into warm water at 36-45℃ and soak for 3-4 hours, and add acid cellulase at the ratio of enzyme activity to the weight of hulled hulls of 30-45IU/g. Adjust the pH value to 5.0 with acid, enzymatically hydrolyze at room temperature for 30-40h; then add hemicellulase at a ratio of 20-30IU/g of enzyme activity to the weight of the hull, and enzymatically hydrolyze at room temperature for 8-10h; then add carbonic acid Adjust the pH value to 8.0-8.5 by sodium, heat up to 75~80℃, keep for 2~3h to inactivate the enzyme, and obtain the crude hull enzymatic hydrolysis solution; filter the hull hull enzymatic hydrolysis crude solution and add 2% of the weight of the filter residue to the filter residue Sodium alginate, 3% chitosan, 4% corn flour, 1% urea, 1% wintergreen oil, fully agitated for 3 hours, dried and granulated to obtain modified hull granules

[0025] (4) Preparation method of Flammulina velutipes cultivation substrate:

[0026] A. According to the formula ratio, mix the above-obtained materials with the rest of the ingredients in the formula, and then add an appropriate amount of water to mix well to obtain the cultivation material, the water content of the cultivation material is 55%;

[0027] B. Bagging: Put the mixed cultivation materials into edible fungus bags, each bag weighs 2.0kg;

[0028] C. Sterilization: steam sterilization at 95-100°C at normal pressure for 18-22 hours to obtain Flammulina velutipes cultivation base.

[0029] The specific process of cultivating Flammulina velutipes with the cultivation base of the present invention is as follows: In a sterile room, the Flammulina velutipes fungus is seeded on the empty rod of the Flammulina velutipes cultivation substrate formula of the present invention, and only 5 hole seeding points can be selected on each rod. The base is called the fungus stick. The fungus stick is cultivated indoors, and the indoor temperature is controlled at 25°C; after the enoki mushroom grows a 3cm-high seedling, it is transferred to the shady ground in the orchard forest to let the enoki mushroom grow naturally, etc. Flammulina grows up and can be harvested.

[0030] Example 2

[0031] The composition of this example is basically the same as that of Example 1, except that when preparing the cultivating base, for every 1000 kg of the cultivating base, a mixed powder of 0.1 kg of garlic powder, 0.3 kg of Gynostemma pentaphyllum powder, and 0.3 kg of millet pollen is added.
