Do a good job in the management of the emergence period of Pleurotus ostreatus

At present, Pleurotus ostreatus is in the stage of mushroom production, so mushroom farmers should do a good job in the management of this period and obtain higher yield. Water management is very important in the production of edible fungi, and the water transfer of the overlying soil layer is an important technical link in water management. There are two methods to choose from: one is to adopt the method of spraying, the mist is clouded, so that the overlying soil layer is not drenched but soaked, and it takes 1 to 2 days to make the overlying soil layer reach the maximum water holding capacity. This method has little effect on the hyphae in the overlying soil layer and is suitable for partial clayey soil. The second is to re-bind mushroom water, the method is to adopt the method of sprinkling and use enough water at one time. The biggest advantage of this method lies in the use of heavy water, which can effectively stimulate the rapid transformation of hyphae from vegetative growth to reproductive growth, and adapt to the soil-covering materials with better physical and chemical properties. After that, measures such as space spray should be taken to keep the air humidity in the shed at 85% and 95%. 2. Temperature management at this stage, the temperature of the mushroom shed is generally 11 ℃ ~ 20 ℃, which is in the suitable range of fruiting body growth of Pleurotus ostreatus, and it can grow normally without any regulation. However, with the decrease of the temperature, the heat preservation measures should be strengthened, which can be adjusted by adding a layer of plastic film on the grass grass and ventilation at noon. At this point, the management of the winter warm greenhouse is relatively simple, while the ordinary inclined greenhouse is difficult to maintain the required temperature after late November or December. In recent years, some producers have achieved good results by using fire walls, soil heating and other methods, and their fruiting body growth requirements can be met as long as they are kept above 8 ℃ in low temperature season. If the greenhouse water temperature air conditioning can be installed under certain conditions, the temperature can be regulated within a certain range. Third, the ventilation effect of ventilation management in the mushroom shed is directly related to the yield and quality, but most mushroom farmers often attach importance to temperature and water management, but ignore the ventilation management as the main factor. The ventilation in the mushroom shed, in addition to the growth needs of mycelium and fruiting body, plays a very important role in removing or diluting carbon dioxide and taking the excess water out of the shed, especially when the humidity in the shed is too high and the fog is too heavy. this is even more important. In addition, good ventilation can reduce the occurrence of some diseases in the shed. Production generally requires that the concentration of carbon dioxide in the shed is about 0.05%, not more than 0.1%. The intuitive feeling is that the smell in the shed is very small, and there is no obvious strong smell of dung and grass fermentation. However, there should not be too strong wind blowing directly on the border surface, otherwise it is easy to cause soil cover or base material to lose water. 4. the most important feature of light management is that the fruiting body can grow normally without light, but under the condition of weak scattered light, it does not hinder its growth and development. therefore, the cover of the mushroom shed can be tightened in the production. Only in the inside operation, open the corner or vent, when there are conditions, you can turn on the light and turn off the human walking lamp. 5. timely harvest when the fruiting body grows to more than 4 cm in diameter and is still in a tight state, but the long speed decreases obviously, it can be harvested in time. The preparatory work for harvest should be done in advance, for example, latex gloves should be worn during harvest to prevent fingers from being imprinted on the cover, resulting in easy browning and affecting the quality of mushrooms; for example, pots, baskets and other tools for loading mushrooms should be disinfected in advance so as not to pollute the mushrooms. 6. after the first tide of mushroom harvesting after postharvest management, the material bed should be cleaned in time, the mushroom feet, dead mushrooms and cords should be removed, the concave place should be filled, and the three-dimensional essence solution can be applied conditionally, 60 kg per 120 grams of water, 60 square meters of border surface, and water suppression should be carried out to make the mycelium recuperate and recuperate, so as to facilitate the occurrence and high yield of lower tide mushrooms.
