Technical points of water nutrition in Agaricus bisporus cultivation;
First of all, spray "bacteria pressing water" in time. When the mycelium emerges from the bed cover, it shows that the mycelium has developed to the bottom of the material, fully developed in the soil layer, and has the ability to set mushrooms. At this time, it is necessary to spray bacteria water in time. The methods are: increasing ventilation to make the hyphae on the soil surface lodging; According to the soil bacteria situation, master the water spraying amount, generally about per square meter 1 kg, in the morning and evening, so as to make the soil thickness of 1/2 permeable. After spraying water, hyphae no longer drill out of the soil surface. Combined with ventilation, the water loss on the soil surface turned slightly white, and hyphae grew horizontally under the soil layer, reaching physiological maturity and transitioning to reproductive growth.
The second is to spray "mushroom water" again. Squeeze mushroom water for 3 days and spray mushroom water. According to the water content of the culture material and the water content of the covering layer, spray it for four times according to the dosage of about 3 kilograms per square meter until the covering layer is soaked in water but has no leakage. The soil layer is not soaked thoroughly, indicating that the water is not enough, and there is water in the soil layer infiltrating into the base material, indicating that too much water may have an adverse effect on the later results. Ventilation should be strengthened when spraying mushroom water, and forced ventilation measures should be taken if conditions permit. Small mushroom buds can be seen after 2 ~ 3 days.
Third, spray enough "mushroom water". The water consumption and spraying method of mushroom water are similar to those of mushroom water. At this time, mushroom buds have appeared, so pay attention to the water temperature as close as possible to the greenhouse temperature, and don't make the temperature difference too large; Where there are mushroom buds, it is important to spray them a few times less and the total amount should be sufficient, but it is still important to pay attention to the fact that no water penetrates into the base material in the soil layer.
Fourth, spray "maintenance water". Every day according to the weather conditions, such as rain or shine, temperature, ventilation, etc. , should master the number of water spraying and water consumption, keep the air humidity at about 90%, and make the covering soil surface basically wet. With the continuous growth of fruiting bodies, the frequency and water consumption of water spraying will also increase. When the diameter of mushroom cover is 1 cm, the edible mushroom three-dimensional nutrition essence can be directly sprayed once a day in June 65438+1October, and once every other day after the middle of June 65438+1October, and water can be sprayed on the fruiting body according to the humidity in the shed.
