在塑料棚内用塑料袋栽培平菇,要创造有利于其生长发育的条件,以利健康成长,否则会长出畸形菇,影响产量和质量。一、温度。夜间棚内温度要控制在10—12℃,白天15—18℃。如果气温过低,长出的菇盖厚、无柄,且生长缓慢,白天就需要增加阳光透入,以提高气温,夜间要管好炉火,使烟筒、火墙等正常放热。如果局部温度过低,要把料袋移到温度高的地方。棚内气温过高,出菇虽快,但菇柄长,菇盖薄,质量低,这要向空气喷水、放风或撤火,以降低温度。二、棚内湿度。平菇是耐湿性真菌,在出菇期空气相对湿度应为85—95％,湿度小时菇体生长缓慢,无光泽,菌蕾易枯死,菌丝体失水快,长出长柄小薄盖菇。可向空气喷水雾,或向地面洒水,喷 Grow plastic mushrooms with plastic bags in the plastic shed, to create conditions conducive to their growth and development, in order to facilitate healthy growth, otherwise they will grow mushrooms, affecting the yield and quality. First, the temperature. Night shed temperature to be controlled at 10-12 ℃, 15-18 ℃ during the day. If the temperature is too low, grow mushroom cover thick, sessile, and slow growth during the day need to increase the penetration of sunlight to raise the temperature at night to manage a good fire, the chimney, fire wall and other normal heat. If the local temperature is too low, the bags should be moved to high temperatures. The shed temperature is too high, fruiting fast, but the mushroom handle long, mushroom cover thin, low quality, which should be sprayed into the air, air or withdraw fire to reduce the temperature. Second, shed humidity. Pleurotus ostreatus is a wet-resistant fungus, the air relative humidity in the fruiting period should be 85-95%, mushroom body growth slow, dull, bacterial bud easy to die, mycelium water loss quickly, grow long thin handle mushroom. Can spray water to the air, or to the ground sprinkler, spray
