Cultivation of mushroom with raw material

Flammulina velutipes, or Flammulina velutipes, is a kind of fungus that can grow in the severe winter. The fruiting body of Flammulina velutipes is small and beautiful and nutritious. Winter mushroom is a kind of high-grade edible fungus, but its seed production and cultivation are not complicated. At present, clinker cultivation is mostly adopted in China. In order to save energy, reduce and simplify the process of cooking base materials under high pressure or low pressure, the relevant experts have successfully carried out long-term cultivation experiments on raw materials. The new method of cultivating mushroom with raw material is briefly introduced as follows.

The main results are as follows: 1. The cultivation and sowing time of winter mushroom is low temperature fungus, the temperature of mushroom production is mostly between 5-15 ℃, the optimum temperature for fruiting body growth is 5-8 ℃, and the sowing time of raw material cultivation is mostly from October to December, which can also be extended to the Spring Festival.

Second, the preparation of cottonseed husk, wheat bran or other raw materials should be fresh, caking-free, mildew-free, and should be exposed to the sun for 2-3 days, and then used after surface disinfection. The formula of culture material is: 1. Cottonseed hull 78%, wheat bran 20%, sugar 1%, gypsum 1%, carbendazim 0.2%. Cottonseed husk 96%, corn meal 3%, sugar 1%, carbendazim 0.2%. Cottonseed hull 100%, carbendazim 0.2%. Note: when batching, the ratio of material to water is 1.2mm 1.4, and the water content is 65% 70%. Mix the material evenly and pile it into a pile, covered with plastic film for 2 hours, if it is not stuffy, or less than 2 hours, carbendazim not only does not play the role of sterilization, but is easy to be harmful, because carbendazim is also lethal to bacteria.

3. Cultivation and sowing methods

1. The raw material is planted in a bottle. ⑦ sowing and bottling. Can use ordinary 500g canned bottle, according to the routine, first disinfect the bottle, and then bottle the culture material. It is better for bottle planting to sow seeds in layers, that is, to install a layer of material, sow a layer of bacteria, sow three layers altogether, and increase the amount of seed in the top layer (that is, seal with bacteria). The strains and materials must be closely combined, and the total amount of seed used should be 10%. When bottling, neither too tight nor too loose, only moderate tightness is conducive to bacteria, after sowing, you can use plastic film to seal the bottle and tie it tight. ② germ culture. Send the bacteria bottle into the culture room to send bacteria, pay attention to shading the room to form a dark room effect. When the room temperature is controlled at 5: 12 ℃, the mycelium can be filled in about 30 to 35 days, and the vegetative stage can be completed. ② growth culture: move the good bacteria bottle to the mushroom to promote the production of mushrooms, first remove the plastic at the mouth of the bottle, cover the mouth with newspaper, and spray water to keep the newspaper warm. The room temperature is controlled between 5-15 ℃ and the relative air temperature is controlled at 80%-90%. When the fruiting body appears, in order to make the blossoming perfect and neat, good quality of mushroom production, and prevent the stalk from bending and lodging, it is necessary to cover the bottle mouth with a hard paper tube of 8 cm and 10 cm, and tie 4 to 5 small holes in the paper to facilitate ventilation. The paper tube is large and upward, and the small mouth is placed on the bottle mouth, which is firmly fastened with a rubber band. at the same time, the newspaper is also covered on the paper slips, and the newspaper is often kept moist, so as to protect moisture and light. In addition, water should be splashed on the ground. Spray in the room. In this way, the first stubble mushrooms can be picked in about 15 to 20 days. When harvesting, clean mushrooms should be collected without leaving residual mushrooms, do not damage the bacterial lumps, tidy up the material surface, make the mycelium grow again for a few days, and then spray heavy water once every two days. After covering a few days, the second stubble mushrooms can grow, and about 3-4 stubble can be harvested. 2. Bed planting and block cultivation: intensive production is often adopted in large area cultivation. If family cultivation, you can use the space under the bed and table, but the site must be strictly disinfected and sterilized. ① bed planting. For the production of bacterial bed, the width should not exceed 80 cm and the length is unlimited. Sowing can be divided into three layers by the combination of layering and on-demand sowing, and the technical measures can be taken in accordance with the routine. ⑦ lump cultivation. Using wood mold to press the block, the wood mold specification is generally 50cm x 35cm xlo cm, sowing mode, either on demand or mixed sowing. No matter which cultivation method is adopted, the fungus, mushroom, harvest and management can be carried out according to the routine.
