食用菌在不同的光照条件下培养，生长状态不相同，其出菇时间、出菇周期、子实体长势、子实体各部位生长状态、菌包产量等都存在一定的差别。本实验通过设置自然散射光条件下不同光照强度，作为林下模拟条件的变量，对平菇在不同光强条件下进行出菇培养，观察子实体生长状态特征并分析其变化差异。结果表明：光照度1500 Lx以上不利于平菇均匀生长，菌株间差异大；光照度50 Lx以下光强也不利于平菇菌盖的生长及幼小菇的发育；光照度500~1000 Lx条件下平菇子实体的生长发育情况均匀，菌柄菌盖生长比例适中，产量大，适合食用菌的生产及林下经济的发展。
The edible fungi cultured under different light conditions have different growth states, such as mushroom emergence time, mushroom emergence cycle, fruiting body growth, growth state of each part of fruiting body and the yield of fungus pouch. In this experiment, different light intensities under natural scattered light were set as variables of simulated conditions in the forest, and the mushroom was cultured under different light intensities to observe the characteristics of fruiting body growth and analyze the variation. The results showed illumination above 1500 Lx is not conducive to the uniform growth of Pleurotus ostreatus, and the differences among strains were large. The light intensity below 50 Lx is also not good for the growth of mushroom cap and the development of young mushroom. Under the condition of 500~1000 Lx illumination, the growth and development of fruiting bodies were uniform, the growth ratio of stalk and cap was moderate, the yield was large, which was suitable for the production of edible fungi and the development of under-forest economy.
