How to make wheat grains spawn of morel mushrooms?
1. Formula
75% wheat grains, 10% cottonseed hulls, 11% corn cobs, 2% soybean meal, 1% gypsum, 1% quicklime (increase or decrease according to pH value).

2. Raw material processing
(1) Soaking wheat grains: Use a cement pool or a temporary one-time water pool with enclosures, shovel the wheat grains into the pool, add about 1% quicklime, and add water to submerge the wheat grains by more than 15 cm. During the process, add water according to the water absorption of the wheat grains to keep the wheat grains in a soaking state. The soaking time is controlled according to the water temperature. The water content of the wheat grains should be 38%~42% when the wheat grains are fully absorbed, there is no white core when the wheat grains are twisted open, and the skin is not swollen and broken.

(2) Auxiliary material processing: Cottonseed hulls and corn cobs should be prepared more than 12 hours in advance, and a mixer should be used to add enough water to mix and pile them up. Drain the clear water naturally and set aside. The water content should be 62%~65%.

3. Mixing
The water in the wheat grain soaking pool should be drained 4 hours in advance and drained until there is no visible water. Use a forklift to shovel the wheat grains into the mixer, shovel in the corresponding proportion of pre-wetted auxiliary materials according to the ingredients, add soybean meal and quicklime, and stir directly for 5 minutes without adding water before use.

4. Bagging
The mixed wheat grain material should be used as soon as possible and used up within 30 minutes to avoid the wheat grains from bursting and causing starch to be squeezed out and become sticky. Use a punching bagging machine, the plastic bag has a folding diameter of 17 ~ 18.5 cm, the filling height is 15 ~ 17 cm, it is loose and natural, insert a punching rod in the center, put on the ring, and cover the lid.

5. Sterilization
The wheat grain strain must be sterilized in an autoclave, and the parameters are as follows:
The first stage is heated to 100℃ and 30 minutes;
The second stage is heated to 110℃ and 30 minutes;
The third stage is 122℃ and 150 minutes, and then stewed for 30 minutes.
Other process operations are the same as the production of mushroom bags.
