Technical points of providing water nutrition for Agaricus bisporus during planting;
First of all, spray "bacteria-pressing water" in time. When hyphae emerge from the overburden layer of the bed surface, it means that hyphae have developed to the bottom of the material and fully developed in the soil layer, and have the ability to set mushrooms. At this time, bacterial water should be sprayed in time. The method is: increase ventilation to make the hyphae on the soil surface lodging; And according to the soil bacteria situation, master the water spray amount, generally about per square meter 1 kg, divided into morning and evening, to achieve the purpose of making the soil thickness 1/2. After spraying water, hyphae no longer drill out of the soil surface, and combined with ventilation, the soil surface loses water and turns slightly white, and hyphae grow and connect horizontally under the soil layer, and reach physiological maturity and transition to reproductive growth.
The second is to re-spray "mushroom water". The fruiting water is sprayed after 3 days of pressing the mushroom water. According to the water content of the culture material and the water content of the overburden layer, it is sprayed in four times according to the dosage of about 3 kg per square meter until the overburden layer is soaked with water but there is no seepage. The soil layer is not soaked, which means that there is not enough water, and there is water in the soil layer infiltrating into the base material, which means that too much water may have an adverse effect on the later fruiting. When spraying mushroom water, ventilation should be strengthened, and forced ventilation measures should be taken if conditions permit. Small mushroom buds can be seen after 2 ~ 3 days.
Third, it is necessary to 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 do not make the temperature difference too large; Where there are mushroom buds, it should be sprayed several times and less, and the total amount should be sufficient, but it is still very important to pay attention to the fact that there is no water infiltrating into the base material in the soil layer.
Fourth, spray "maintenance water". Every day, according to the weather, such as rain or shine, temperature, ventilation, etc., we should master the water spraying frequency and water consumption, keep the air humidity about 90%, and make the covering soil surface basically wet. With the continuous growth of fruiting bodies, the spraying frequency and water consumption should also be increased. When the cap diameter reaches 1 cm, the edible fungus three-dimensional nutrient essence solution can be directly sprayed once a day in1October, and once every other day after1October, and water can be sprayed to the fruiting bodies according to the humidity in the shed.
