Choosing the right mushroom spawn is key to autumn oyster mushroom cultivation
Spawn quality is the key to a bumper oyster mushroom harvest. High-quality secondary and tertiary oyster mushroom spawn should have the following characteristics: dense, pure white mycelium, uniform and sturdy growth, cottony in appearance, with climbing phenomenon on the container walls, and a small number of coral-like tiny mushroom buds appearing on the surface of the substrate; the spawn age is best at 20-25 days; the mycelium is clearly visible on the cross-section of the spawn, with a distinct mushroom aroma. If a large number of fruiting body primordia appear on the surface of the substrate, it indicates that the spawn has matured and should be used as soon as possible.

High-yield cultivation method of cutting oyster mushroom blocks into pieces, standing them upright and covering with soil
Mushroom farmers in Dongkan Town, Binhai County, Jiangsu Province, through years of oyster mushroom cultivation practice, worked out the six-character high-yield formula for oyster mushrooms of "cutting into blocks, standing upright, covering with soil", which increased the oyster mushroom yield per mu by more than 2000 jin compared with the past, with an increase rate of about 30%, and at the same time, production costs dropped greatly. Their high-yield experience mainly consists of three steps: "cutting into blocks, standing upright, covering with soil". The so-called "cutting into blocks" means that at the end of harvesting the second flush of mushrooms in furrow-bed cultivation, the dead mushrooms, stipes and the like remaining on the bed surface are cleaned up, and a sharp knife is used to cut the cultivation substrate into multiple pieces of about 50 cm
