Last Updated: 2024/11/22, The mushrooms began to emerge 15 days after sowing the grass (the fastest week or so). The harvest time of commercial volvariella volvacea is when the buds will break and the cap in the fungal receptacle is not opened. The specification for canning is more than 2 cm in diameter, the bacteria shape is neat, the outer bacterial curtain is not broken, and the stalk in the inner package is not elongated. The requirement for the supply of dried mushrooms is more than 4 cm in diameter and the external fungus curtain is not broken. The quality of the broken external fungus curtain is slightly worse, and the umbrella opening is even worse, the latter can only be sold as external-grade fresh mushrooms. Those who supply dried mushrooms should cut the buds into two connected halves and drain the bamboo.
