Harvest and processing of Pleurotus ostreatus
7-10 days after the mushroom bud grows, the stalk is 4-5 cm long. When the cap is about to be carried out, it should be harvested in time. The harvested mushrooms should be immediately cut off the aging roots, and then sold fresh or sent to the factory to be canned and processed into salted mushrooms. If the saltwater mushroom is processed, 10% salt water can be used. After boiling, pour the fresh mushroom and turn it up and down for about 10 minutes. When the pot boils and tumbles, pick it up quickly, put it in cold water to cool, and finally marinate it with Baume 20 degrees saturated salt water. With 35% salt of mushroom weight, a layer of mushrooms is stacked in the tank, and when filled, cover the surface with salt 2cm thick and press the weight so that the mushrooms do not come out of the water. After 18-20 days, the barrel can be filled.

Curing Technology of fresh Mushroom
1. Selection of fresh mushrooms: fresh mushrooms salted with salt should be harvested in time to remove impurities, diseases, insect hazards and moldy parts. The cover of fresh mushroom is required to be complete, the root of fresh mushroom is removed, the fruiting body of Pleurotus ostreatus is broken one by one, and the deformed mushroom is eliminated; the aged stalk of Pleurotus ostreatus and hericium Erinaceus should be removed. It is worth noting that the fresh mushrooms harvested on the same day should be processed on the same day and should not be processed overnight. 2. Rinse fresh mushrooms: put 0.3 kg of salt in 50 kg of water. (don't be too thick, or the mushrooms will turn red.) turn into 0.6% salt water and wash off the surface of the fresh mushrooms.

Main control methods of diseases and pests in mushroom shed
The main results are as follows: 1. Mushroom fly larvae, also known as maggots, mainly feed on the fruiting body to cause tunnels and affect the quality, and the resulting wound is also easy to be infected and rotted by bacteria. Different methods should be used to control mushroom flies in different periods. There are a large number of maggots in front of this mushroom, which can be fumigated with dichlorvos at the amount of 0.90 kg / 100 square meters, while 0.15 kg of 1% potassium chloride or sodium chloride solution is sprayed on each culture block (which can be replaced by 5% salt water). After mushroom, maggots can be sprayed with low-toxic pesticides such as fish rattan essence, pyrethroid, nicotine and so on. (smoke
