光质对金针菇子实体生长发育的影响

Effects of Light Quality on the Growth and Development of the Fruitbody of Flammulian velutipes (Fr.) Sing.

作者以金针菇Ｆｌａｍｍｕｌｉｎａ ｖｅｌｕｔｉｐｅｓ的黄色品系为材料，对即将出菇的栽培袋分别进行红、橙、黄、绿、青、蓝、紫色照光处理，另分设黑暗和室内散射光照射为对照处理。结果表明：不同光质的照光处理（５０Ｌｘ）均可诱导金针菇子实体原基的提早形成，缩短生产周期，增加产量，增产幅度为４６．４１％￣７０．２４％，其中以黄光，绿光、紫光、青光照射增产效果最佳。散射光照射不利于金针菇产量与品质的提高；

With the yellow strain of Flammulina velutipes (Fr.)Sing. as experimental material, the cultural bags in which Flammulina velutipes were in the point of fruiting were irradiated with red, orange, yellow, green, light blue, blue and voilet light,respectively. Meanwhile, dark and indoor scattered light were used as comparison. The results showed that all special spectrumrays induced the earlier formation of the fruitbody buds of Flammulina velutipes, shortened the production cycle and increased the yield by 46.41% ~ 70.24%, the yield increased the most with the irradiation of yellow, green, voilet and light blue. Scattered light was not favorable to the yield and quality of Flammulina velutipes. Under complete dark enivronment, the fruitbody buds appearance delayed, grew in bad order, and the yield decreased significatly.Considering the balance of yield and quality, yellow and red light were the best.
