The key to improving the rate of adult mushrooms is to control the position of the proper mushroom. In production management, the following three measures are taken:
First, the soil is still in the pre-closure phase
After the first covering of the earth, timely supplement the soil moisture, increase the ventilation, and disperse the odor in the residual earthen soil. After the moisture in the soil is dry, the doors and windows are closed to ensure the micro-ventilation. In principle, the temperature of the mushroom house is maintained at 22 to 24°C, which promotes rapid creeping of the mycelium. Afterwards, the growth of hyphae in the soil layer is often checked. To be sure about 70% of the hyphae are faintly visible between the earth seams, the soil should be filled in time and the thickness should be 0.8-1.0cm. The water content can be slightly dry, which is both easy to operate and causes a kind of Dry and wet state, forcing the hyphae to continue to grow laterally between the first casing layers, and then to climb upwards to facilitate the management of soil mycelium and the control of the position of S. edulis.
Second, control and crane combination
In the later period of the casing soil, the mycelia of the mushroom house grow vigorously, the temperature of the material is high, and if it coincides with the abnormal climate of “Little Springâ€, the indoor and outdoor temperature is high and the humidity is high. First, it is easy to cause soil hyphae to be long, and on the surface, it seems that the hyphae of the soil are prosperous but the hyphae of the bottom layer is empty. Usually, the management of the ventilation of the mushroom house is adopted. At this time, the problem cannot be solved. Water spray suppression of hyphae is a taboo in production. In production practice, each mushroom house (cultivation area of ​​about 400 ?) uses 2 to 3 kg of lime powder, and the mushroom house is sprayed 1-2 times (with an interval of 1 to 2 t) in time to make the mushroom house exhibit low humidity and strong alkalinity in the short term. The environment can effectively control the growth of mycelium and inhibit the growth of pathogenic bacteria that accompany high-temperature and high-humidity growth environment, and it will not cause damage to the mycelium of Agaricus bisporus. The second is to cause bacterial bed, soil mycelium suffocation, affecting the climbing, should increase ventilation, dry soil moisture, restore hypha vitality as soon as possible, to be normal climate, the use of spray, 0.5cm on the cover soil surface nutrition Water 1 to 2 times, so that the soil mycelium recovered as soon as possible, and climb to a suitable location, commonly known as "suspension mycelium."
Third, flexible water
"Amphorae mushrooms follow the water, and will follow the water, and will follow the water to die." The vast number of mushroom farmers from the production practice summed up the experience of the famous, brilliantly elucidated the role and harm of water on the growth of Agaricus bisporus. After about 13t of earth-covered soil, the cover soil was split and the hyphae in the soil layer had been intertwined into a linear shape. Under the premise of avoiding the high temperature above 20°C, the “membrane water†should be sprayed in time to combine with large ventilation to promote mushroom mushroom. The silk rapidly transferred from vegetative growth to reproductive growth. A large number of fruit bodies were formed at a suitable position about 0.5 cm from the surface of the cover soil. The application of moisture during fruiting period should follow the principle of “quasi-steady, regular, regular and heavy†water spray.
