1. Small, high-differentiation, high-differentiation, and long mushroom handle. The reason for this is the formation and differentiation of the primordium, the lack of oxygen in the mushroom house, lack of light, and the high temperature, which affects the normal differentiation and development of the cap. Control methods: Strengthen ventilation, adjust light and temperature.
2. The appearance of tumor cap mushroom cap, there are many granular protrusions on the edge, light color, mushroom cap stiffness, growth retardation, mushroom cap differentiation is poor, irregular shape, because the mushroom body development temperature is too low, long duration , resulting in imbalance of cell growth in the inner and outer layers. Control methods: Adjust the mushroom house temperature above the minimum temperature of Pleurotus ostreatus growth, and there is a certain temperature difference, promote mushroom growth, development, differentiation.
3. Cauliflower mushroom-like cauliflower, more branched, early egg-shaped primordium, swelling, uplift, no differentiation. There are more branches in the later period. The reason is that the mushroom bed or mushroom house was sprayed with a high concentration of pesticides before or during fruiting. Mushrooms contain harmful gases: carbon dioxide, sulfur dioxide and so on. Control methods: mushroom pesticides with caution, concentration can not be too high when used. It is not allowed to use dichlorvos during the fruiting period, and to increase the ventilation and remove harmful gases.
4. Atrophy mushroom body in the swelling period that is yellowing, edema or shrinkage, and stop growing, and finally become soft rot. The cause of edema is that the humidity is too high or there is more water directly sprayed on the young mushroom body. Dry shrinkage is due to the relatively low relative humidity of the air and over ventilation. Control measures: Control the humidity between 80% and 85%, do not spray water on the young mushroom body, and do not let the wind blow directly on the mushroom body. Reasonable ratio culture ingredients. A small number of shriveled mushrooms are due to degradation of the strains. The symptoms are that the caps have not yet grown large enough to rewind, yellow, and shrink. Control methods: use good varieties.
