1. Preparation materials: 38kg of sawdust, 1kg of wheat bran, 1kg of sugar, .5kg of gypsum, .5kg of calcium superphosphate and 35g of carbendazim. 2. Making the culture medium: soak the sawdust in 2% limestone for 12 hours, then mix the raw materials evenly and add water according to the ratio of 1: 1.3, stir and then build a pile for decomposition. The decomposed culture material needs to be disinfected twice, the first time before entering the mushroom house and the second time after entering the mushroom house.

1. Planting and cultivation techniques of Lentinus edodes

1. Prepare raw materials

38kg of sawdust, 1kg of wheat bran, 1kg of sugar, .5kg of gypsum, .5kg of calcium superphosphate and 35g of carbendazim.

2. Making cultivation substrate

(1) Wood chips can be soaked with 2% limestone for 12 hours, or with .2-.3% potassium permanganate solution, generally for about 12 hours.

(2) mix the raw materials evenly, then add water according to the ratio of 1: 1.3, and then stir to build a pile. The pile is 1.2-2m wide and 1-5m high, with a trapezoidal shape, and its length depends on the amount of culture materials and the size of the site. Generally, it takes about 26 days to compost, and it needs to be turned over for 4-5 times during stacking.

(3) Before entering the mushroom house, the decomposed culture materials should be disinfected for the first time, and then disinfected for the second time after entering the mushroom house.

3. Bagging and disinfection

(1) Fill the bag with a cylindrical transparent film bag, and leave a round mouth with a diameter of 3cm at the mouth of the bag and plug the cotton plug to facilitate inoculation.

(2) Sterilize the bag material with a steamer, and when the temperature is cooled to about 35℃, it can be moved into the inoculation room to inoculate Lentinus edodes.

4. Daily management

(1) Put the inoculated bag materials into a culture room to culture the mushroom hyphae, with room temperature of 25℃ and relative humidity of 6-65%.

(2) When the bag material turns yellow, it means that about 4% of the surface hyphae in the bag material have turned brown, and then the bag can be removed and put on the shelf to promote mushrooms.

(3) During the mushroom-growing period, the temperature difference between day and night can be increased by uncovering the film, which is beneficial to the formation of mushroom fruiting bodies.

(4) When the fruiting body of Lentinus edodes reaches 7-8%, it can be picked.

(5) When picking, care should be taken to avoid damaging the surrounding small mushrooms and blocks, thus affecting the subsequent fruiting.

2. How long can mushrooms be planted on the market

1. Generally, mushrooms need to be planted for about 5-6 months before they can be marketed. However, due to different factors such as mushroom varieties and cultivation methods, the time for listing mushrooms is also different. For example, short-lived varieties generally need to be planted for 4-5 months before they can be marketed, while long-lived varieties generally need to be planted for 6-8 months before they can be marketed. Therefore, the specific time for listing mushrooms needs to be based on the actual situation.

2. In order to ensure the normal listing of shiitake mushrooms, it is necessary to cultivate shiitake mushrooms in a well-ventilated place. If this site is the first time to cultivate shiitake mushrooms, it needs to be disinfected by washing the wall with lime water, while the old mushroom farm can be disinfected by fumigation, such as fumigation with potassium permanganate and formalin.

3. If there are pests, it is necessary to kill them with pesticides first, and then disinfect them. Moreover, it is necessary to ensure a certain air humidity in the mushroom farm, but the humidity should not be too high. If the water spraying amount is blindly increased to increase the humidity, it will easily lead to the suffocation of small mushrooms, and some growing mushrooms will also be affected by excess water stains. Therefore, it is necessary to control the air humidity reasonably, not too dry or too wet, so as to ensure that mushrooms can be put on the market normally.
