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. Before introducing spawn, you must first determine the temperature type of the spawn, and then according to

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.

Before introducing spawn, you must first determine the temperature type of the spawn, and then determine the spawn temperature type according to your own conditions and the fruiting temperature. When cultivating oyster mushrooms with substrate in August to September, due to the high temperature, the fruiting period may sometimes see high temperatures above 30 degrees C, while after entering October the temperature will gradually decrease. In order to ensure normal fruiting during both high and low temperature periods, the spawn selected should be an excellent spawn that is both tolerant to high temperatures and capable of fruiting at low temperatures. For oyster mushroom cultivation from mid-August to mid-September, choose Jiangdu 109 and Huafeng No. 1; for cultivation from late September to mid-October, choose Zhu 9703 and P50; for cultivation from late October to late November, choose Heipingwang and 8801. If the temperature type of the selected spawn is inappropriate, it is not suitable for autumn cultivation, so you must be cautious when introducing spawn. In addition, you should choose spawn according to the local natural resources. At present, the main raw materials for oyster mushroom cultivation are cottonseed hulls and corn cobs. Different varieties have different abilities to decompose the substrate, so you should choose spawn suitable for the substrate.
