People can change temperature to induce mushrooms, adjust the temperature of greenhouse in 15 to 28 degrees, uncover plastic film at night and open ventilation hole to increase ventilation, reduce humidity and keep relative air humidity in 85%.
According to climate characteristics of most regions in Henan Province, China. After entering into March, outside temperature begins to rise quickly, when the temperature rises to above 20 degrees, farmers should adopt measures of cooling and increase the thickness of covering, such as covering two layers of grass carpets or a layer of grass carpets and a layer of wheat straw or corn stalk and find other ways to remain natural temperature of greenhouse under 25 degrees.
Normal fruiting and growth can happen when the water content of substrates is in 40% to 60%. When the water content of substrate is under 40%, mushroom buds will be hard to grow. Here are three methods on moisturizing.
1. Injector: use hollow metallic tubes to make injector, 25 cm in length, with pointed cone, hollow heart and more than 20 water outlet holes. When injecting, people can make another water injection hole with the same size on the other side of mushroom bag, take down sprayer of agroatomizer and take up needle of injector, insert injector into water injection hole of mushroom bag and input water into bags with the help of the pressure of sprayer.
2. Soaking and moisturizing: use specialized water-soaking basin or existing pool, put plastic film at bottom of basin, use iron wire to punch hole of 15 cm on both sides of bag, then pour clean water into basin, cover tightly with wooden board and stone to prevent floating up. The soaking time is from 2.5 to 3 hours and no more than 15 hours.
3. Spraying: beat mushroom bags that needs moisturizing for a few times with plum blossom pinboard, use hand-pressure farmland sprayer to or power sprayer to spray on surface of bag, for first 1 or 2 days, farmers should spray frequently and for 3 or 4 times everyday. When mushroom pellicle becomes moist and substrate absorbs certain moisture, amount of water capacity can be increased and spray water on the ground and in the air to accelerate the time of water absorption. In general, water-spraying should be remained for 3 or 4 days.
After two-crops of mushroom bag, because of the temperature of greenhouse get increased and moisture of compost get reduced, the fruiting of mushroom bag will be influenced, farmers can conduct fruiting in greenhouse by earthing.
Because of the temperature is gradually increasing, the growth of Shiitake is quick, so, farmers should observe the growing condition of Shiitake everyday, mushrooms should be picked in six-component mature and be picked for two times everyday when necessary, manage them, pack and cold storage in time.
