Excuse me, is the climate in Yanyuan County, Sichuan suitable for growing mushrooms?

The geographical environment and climate in Yanyuan County, Sichuan Province can be used to grow mushrooms. Mushrooms used to be cultivated with logs or logs in a few areas. Due to the limitation of trees, regions and seasons, the development speed is very slow. At present, production is mainly based on contract farming.

Substitute cultivation is to use various agricultural and forestry by-products as main raw materials and add appropriate auxiliary materials to make culture medium to replace traditional cultivation materials (logs and wood chips) to produce various edible fungi.

First, the production of bacterial bags

(1) formula:

1. poplar sawdust 79%, wheat bran 20%, gypsum 1%, carbendazim 0. 1%(50% wettable powder);

2. Corn cob (crushed to the size of broad bean) 45%, poplar sawdust 40%, corn flour 13%, gypsum 1%, lime powder 1%, carbendazim 0. 1%(50% wettable powder). Wood chips should be aged for more than half a year, and wheat bran must be fresh, free from mildew and moth.

(2) Mixing: after weighing the above raw materials, mix sawdust, wheat bran and gypsum together, stir them evenly, turn them over for 4-5 times, then put carbendazim and lime into water, stir them evenly, and spray them into dry materials with a watering can. While watering, mix the materials evenly, and adjust the water content of the culture material to about 60% (that is, when the material is pinched by hand, the wet material will agglomerate, and water drops will appear between fingers but not drop).

(3) Bagging: low-pressure polyethylene film is used, with the size of large bag being 25 × 55cm and the size of middle bag being 17 ~ 20 × 55cm. The big bag can hold 2.0 kg of dry material, and the middle bag can hold about 1.5 kg of dry material. Before loading, seal one end of the plastic bag until it is completely sealed. Put the evenly stirred culture material into a bag with appropriate tightness. There is no softness in the middle of the hand-packed material package and there is no sag at both ends.

Second, sterilization.

1. Construction of steamer: Choose a large iron pot with a diameter of 1.5m to build a steamer with a length× width× height of 2× 2× 2.5m and a volume of 8 ~ 10 m3. The inside and outside of each pot wall shall be polished with high-grade cement, and a curtain with a diameter of 1.7m shall be made of wood squares or iron bars, which shall be placed on the pot surface and covered with sacks to prevent the material bags from being punctured. Then make a pot cover with a diameter of 2. 1m from galvanized sheet with a thickness of 1.5mm, and build a steamer for later use.

2. Add water to the pot: Before fire sterilization, add enough water to the pot, and the water level in the pot is about 20 cm away from the curtain. Then align the stuffed bags up and down and put them on the curtain in the steamer in batches.

3. Ignite, heat and sterilize: ignite the fire before filling the pot to make the temperature in the pot reach 100℃ for 4 ~ 6 hours, then continue to heat and keep the temperature at 10 hour, and then keep it stuffy for one night. When the feed temperature drops to 70℃, grab the temperature and take it out of the pot, quickly move it into the cooling room, and then inoculate it after the temperature in the feed bag drops.

Third, vaccination.

1. Disinfect rooms: 4 days before use, put the discharged tools into indoor sealed doors and windows to achieve indoor sealing without air leakage, ignite each room with sulfur, and fumigate the rooms.

2. Inoculation time: When the bag temperature drops to 30℃, planting should be started, and the inoculation time should be arranged in the morning and evening.

3. Inoculation procedure: It is advisable to have four people, do a good job of division of labor, operate, light alcohol lamps, beat strains, take strains, mix bags and tie strains, and seal. The finished fungus bags are stacked in a "well" shape, with 5 layers in each pile.

Fourth, fungal culture.

1, keep the room dark and control the room temperature at about 25℃.

2. After inoculation with 16 ~ 20 days, prick 10 ~ 20 holes with a depth of 0.5 ~ 1.0 cm at the inoculation point with a toothpick. Use a sweater needle for the second time and chopsticks for the third time, once every 10 day, gradually increasing and deepening.

V. Color management

Generally, discoloration is carried out between spawning rooms. To make the room temperature reach 20 ~ 30℃, take off the bag, soak the bacteria tube with lime water and take it out. Always ventilate, but not for too long at a time. Generally, 30 minutes is appropriate.

6. Result period management

1, mushroom shed construction can make use of existing greenhouses or greenhouses. If you want to build a new greenhouse, you can choose a place with sunny lee, dry and flat terrain, clean and sanitary environment, sufficient water and convenient access to materials, such as in the courtyard, in front of the house, near the village, in the orchard, and in the open space among trees. The film in the greenhouse is covered with grass curtains or umbrellas.

2, the bacteria bag is discharged; Put it horizontally on the bedstead, and the bag spacing is about 4 cm. Each layer can discharge 42 ~ 44 large bags of bacteria bags. In order to make it easier for the bacteria bag to replenish water, it is best to build a soaking pool near the shed.

3. Changing temperature to promote mushroom growth: The temperature difference between day and night in the greenhouse must be above 10℃ to stimulate the formation of mushroom buds. Keep the humidity in the shed at 85%. Where conditions permit, the method of urging flowers and mushrooms can be used to produce more flower mushrooms and create better economic benefits.

Seven, harvesting

1, discard the inferior and keep the superior: if the young mushrooms grow too densely, they should be picked properly and kept at a uniform distance.

2, early spring or late autumn can be heated by fire, and it will bear fruit sooner or later. When the weather is cold in winter, the fungus bags can be folded together for the winter. When the temperature rises next year, mushrooms will grow again.

The collected mushrooms can be sold fresh or dried. After harvest, let the vat rest to cultivate bacteria, accumulate nutrition, and provide sufficient nutritional conditions for the next batch of mushrooms.
