What to do when pinheads grow on the spawn blocks after inoculating straw mushrooms
2-3 days after inoculating straw mushrooms, many white pinheads grow on the spawn blocks exposed above the compost, causing the spawn to age and affecting the spawn's mycelial germination, or the mycelium grows but does not colonize the compost. The cause is that the spawn is stimulated by strong light, causing some hyphae to knot prematurely and form pinheads. Control method: when inoculating, do not leave the spawn exposed; it should be sown 2-3 cm deep into the compost, and a straw mulch should be used to shade and keep warm, preventing stimulation by strong light.
