Abstract

Abstract:

To explore the precise application of LED light source in the cultivation of straw mushroom and provide a theoretical basis for the cultivation of factory straw mushrooms, straw mushroom V23 was used as the material, six different treatments of LED light quality were set as: control white light (CK), red/blue=1∶1, red/blue=1∶2, red/blue=2∶1, single red light, single red light. The results showed that when the ratio of red light to blue light was 1∶1, the mycelial growth was strong, and the effect on other indexes was not obvious. The results showed that the red and blue light ratio of 1∶2 had a significant (P<0.05) effect on the growth of mycelia, and it had a promoting effect on the growth of mycelia, followed by the red and blue light ratio of 1∶1, and the effect of LED light quality on the growth of mycelia was mainly concentrated in the early stage, but not in the late stage. The ratio of red light to blue light was 1∶2 and 1∶1 showed the most effect on the mycelial biomass, which was significantly (P<0.01) higher than that of CK by 28.29% and 19.97%, respectively. At the same time, the mycelial branching distance in the treatments of red and blue light ratio of 1∶2 and 1∶1 was relatively small, and the mycelial branching distance was reduced by 16.03% and 15.13%, respectively. The mycelial growth was relatively strong and dense.

Key words: LED light, light quality, straw mushroom, mycelium growth rate, mycelium biomass, mycelium branch distance
