Treatment of Pleurotus ostreatus during tide turning period
Pleurotus ostreatus is in the tide-turning period, first of all, remove the mushroom root and dead mushroom, dig up the root with a sharp knife, do not leave, pull out the dead mushroom.
Secondly, the wall mushroom should be drilled with a stick with a diameter of 2cm~3cm, from top to bottom to the bottom 20cm, and then the prepared nutrient water should be added from the hole, less frequent irrigation, and enough water. Nutrition water can be used to clean rice water, mushroom root soup, urea water and so on. Mushrooms planted on the ground can pour nutritious water into the pond together with the water.
Third, stop the water for 5-7 days after filling the nutritious water, when the air humidity is kept at 70%-80%, neither too low nor too high. When the humidity is less than 70%, the dry and hard surface of the cell will affect the lower tide mushroom; when the humidity is higher than 80%, the lower tide mushroom will occur as early as possible, and in the case of insufficient nutrition, the small mushroom bud will die due to lack of nutrition.
Fourth, in the turning tide stage, the temperature can be properly raised to make the hyphae recuperate and lay a good nutritional foundation for low tide mushrooms. At this time, it should be noted that the temperature in the bacteria should not exceed 25 ℃, otherwise, the hyphae will die under the condition of high temperature. If it exceeds 25 ℃, it should be cooled and irrigated in time.
Fifth, after 5-7 days, increase the air humidity to 80%-90%, and carry out the normal management of lower tide mushrooms.

Main cultivation techniques of Pleurotus ostreatus
(1) preparation of cultivation site at present, there are two main ways to cultivate Pleurotus ostreatus in Guangdong: indoor bed cultivation and bag cultivation. The mushroom room for indoor bed planting can be rebuilt from ordinary house, pig house or warehouse, or a simple mushroom room can be built. The bed frame can be built in the room, and the bed frame method can refer to the specification of the bed frame in straw mushroom room. Plastic bag cultivation can be carried out indoors or under plastic sheds or other scaffolding, without the need for a bed frame. All cultivation fields are preferably cement floors or covered with thin film. It must be cleaned before cultivation, and disinfection measures should be taken for the reconstruction of old mushroom houses or pig houses and warehouses.
