What are the high-yield cultivation methods for lion's mane mushroom?
What methods can achieve high yields when cultivating lion's mane mushroom? Please provide guidance. To achieve high yields in cultivating lion's mane mushroom, attention should be paid to the following aspects: First, select good-quality spawn. The mother culture used for production should have excellent traits, shown by fast growth, uniform and neat growth, and covering the slant within two weeks at the optimal temperature. When stored in a refrigerator, primordia often form, and microscopic examination shows a small number of chlamydospores. If there are too many spores, the yield tends to be low. If the mycelium turns yellow, is thin and weak, or sparse, it indicates that the spawn has degenerated. Uneven or irregular growth, or antagonistic phenomena, indicates that the spawn is not pure, and none of these should be used. All stock spawn should be dense and white, uniform from top to bottom, with no breaks in the mycelium, and vigorous mycelium on the surface. If the substrate shrinks, separates from the container wall, and the color darkens, it indicates that the spawn has aged. If stripes or spots of various colors appear around the wall, it indicates contamination in the spawn, and it cannot be used. Second, the age of the spawn must be appropriate. Generally, mother cultures and stock spawn stored in a refrigerator should not exceed 3 months, and at room temperature (20°C) should not exceed 20 days. If the spawn age is too long, its vigor declines, resulting not only in slow growth and low yield, but also poor stress resistance and high susceptibility to contamination. In addition, excellent varieties suitable for local production should be selected.
