Is there marsupial cultivation in Baise, Guangxi? I want to grow bagged mushrooms in Longlin, Baise, but I don't know.

There are bagged mushrooms in Baise, Guangxi, and the specific planting projects of bagged mushrooms are as follows:

One: bagged mushrooms

Substitute cultivation of Lentinus edodes is another cultivation method after log or log cultivation. Its cultivation forms are various, which are mainly designed according to the different cultivation conditions, materials and containers. It has developed rapidly in recent years, accounting for more than 95% of the planting area. Its culture medium takes sawdust, crop stalks and weeds rich in cellulose, lignin and hemicellulose as the main culture materials, and is properly matched with bran, rice bran and gypsum rich in organic matter and vitamins.

2. Cultivation methods

1. culture time

The determination of cultivation time varies with varieties and local climatic conditions. At present, the excellent strain "7402" screened by Shanghai Academy of Agricultural Sciences is mostly used in mushroom brick cultivation, which has the advantages of fast fruiting, long fruiting period and high yield. When the temperature is 5 ~ 20℃, fruiting bodies can be formed. Generally, the original seed is prepared in early June. Mycelium culture was carried out in August, and bottles were dug and pressed in the first and middle days of1October. Mushrooms began to grow in the late month of 1 1 and were harvested in May of the following year.

2. Preparation of culture medium

Sawdust or bagasse 78% wheat bran or rice bran 20% sucrose 1% gypsum powder 1%

Weigh and mix the raw materials according to the above formula, add appropriate amount of water, stir evenly, the water content is about 65%, adjust the pH value to 5.5 ~ 6, then put them into a jar or polypropylene plastic film bag, autoclave and cool for later use.

3. Inoculation culture

The sterilized bags or bottles are moved into a sterile room or an inoculation box, and the original seeds are inoculated through aseptic operation. Each bottle of original seed can be inoculated with 70 ~ 80 bottles (bags). After inoculation, move the bottle or plastic bag into the culture room in time and culture at 23 ~ 26℃. Because most of the temperature is high at this time, we should try our best to cool down and not exceed 26℃. Attention should be paid to mycelium growth and the occurrence of miscellaneous bacteria during culture, and measures should be taken in time to overcome the bad situation. Generally, after 50 ~ 60 days of culture, the mycelium covers the whole bottle, and when it reaches physiological maturity, it can be dug out and pressed into bricks.

Step 4: pressing the fungus brick.

When the temperature drops below 25℃, the cultured mycelium can be dug out of the bottle together with the culture medium. When digging a bottle, dig out the aging bacteria on the bottle surface first, and then dig out the whole bottle, so it won't be too broken, which is beneficial to restore mycelium growth after pressing bricks. When pressing bricks, a movable wooden frame with a length of 45cm, a width of 25cm and a height of 5-6cm is placed on the plastic film of the cultivation frame, and then the excavated mycelium culture material is poured into it, leveled, compacted with a palm or a wooden board, and the edge is slightly pressed to facilitate molding. Each piece is 3 ~ 4 cm apart and well ventilated. After filling a shelf, cover it with plastic film immediately, which is convenient for heat preservation and moisturizing culture.

manage

After brick pressing, the temperature should be controlled within the range of 20 ~ 25℃. After 3 days, white pure hyphae germinated on the surface and gradually healed. After 7 ~ 10 days, the surface of mushroom brick gradually changed from white to light brown and then to brown, and formed a protective film, which became a block. In the meantime, we should pay attention to management. Do not tilt the film for one week after pressing the brick. Only when there is a high temperature above 26℃ and yellow water droplets are produced on the surface, the film will be inclined to cool down. This can not only prevent hyphae from growing white, but also control the spread of miscellaneous bacteria. After one week, the film can be uncovered and ventilated, and the number of times depends on the temperature. At high temperature, once in the morning and once in the evening, and below 20℃ for several days. After two weeks, when the reddish-brown water accumulates, it must be dried with clean gauze. But you can't move the mushroom brick to avoid water accumulation at the bottom; It will cause the brown biofilm to thicken and affect the fruiting.

The surface discoloration of mushroom brick is closely related to mushroom production. According to experimental observation, dark brown skin is late and sparse. But the flowers are big; Yellow-brown, early flowering, high density, middle flowering and high yield; Gray, early and dense mushrooms, but the quality of small flowers is poor. Generally speaking, the speed and depth of discoloration are closely related to the age, temperature, substrate and illumination of the bacteria except for the variety. Therefore, attention should be paid to mastering these conditions in training.

Generally, with proper management and suitable conditions, mushrooms can grow in one month after pressing bricks. After fruiting, the mushroom bricks should be arranged in herringbone shape to expand the fruiting surface. And pay attention to the following aspects.

Three: pest control

In the process of anti-bacterial culture, bricks are often damaged by green mold pollution, which mainly comes from incomplete disinfection of strains, mushroom houses and utensils, and high temperature and sultry indoor. In addition to strict disinfection in the process of aquaculture management, measures should be taken to prevent and control green mold pollution when it occurs. If the mycelium of pressed brick has not healed, Penicillium will appear. It is necessary to ventilate and cool down first, and then scrub it with lime water after healing, so as to change the pH value and control its growth and spread. If it has penetrated into the fungus brick, you can dig out the infected part and replant it. Individual seriously polluted mushroom bricks can be moved outdoors, washed with clear water, dried for 2 ~ 3 days, and then the infected parts are dug up for replanting or resection, and then moved back to the cultivation room to cultivate mushrooms.

Four: Matters needing attention

1. At the initial stage of water replenishment, the moisture content of mushroom bricks is about 60%, which can meet the moisture requirements of the first batch of mushrooms without direct water spraying. Only increase the relative humidity of the air in the mushroom house. In the middle stage, the mushroom brick gradually dries. According to the weather, spray some atomized water on the mushroom brick to improve the humidity. Generally, the relative humidity of the air should be kept between 85% and 95% after fruiting. In the later period, the fungus brick is relatively dry, but the surface fungus film is thick and hard, so it is difficult to inhale by spraying water, so it should be soaked in water to make it fully absorb water. Generally, soak in water at 20℃ for 8 ~ 12 hours to make the water content reach 50% ~ 55%, and then put it on the shelf to continue fruiting. After harvesting a batch, soak it in water until the mushrooms are finished.

2. Ventilation and cooling During the fruiting period, the indoor air should be kept fresh, especially in the early and late stages. The temperature is high, which is not suitable for the requirements of fruiting, and it is easy to cause harmful bacteria, so it is necessary to open the window for ventilation and cooling at night.
