Do not use cottonseed hulls with a high content of cottonseed kernels directly for cultivating oyster mushrooms
Cottonseed hulls consist of the hulls left after the kernels are removed from cottonseed, the short cotton lint attached to the hulls, and a small amount of broken cottonseed kernels. Cottonseed hulls are rich in nitrogen, phosphorus, potassium, cellulose and lignin, with a carbon-to-nitrogen ratio of 79-85:1, are slightly alkaline, loose outside and dense inside, have good air permeability and strong water retention, and are a top-grade material for edible mushroom cultivation. However, cottonseed hulls contain toxic substances, and after sterilization under high pressure or normal pressure they release aldehydes, ketones and acids, and these toxic substances inhibit mycelial growth, delay pinning, and cause undesirable outcomes such as small mushrooms and poor mushroom quality.

Detailed Explanation of the Content of Edible Mushroom Spawn Quality Standards
Grade 1 spawn: For oyster mushroom, Hypsizygus marmoreus (shimeji), enoki mushroom, Pleurotus nebrodensis (white lingzhi mushroom), king oyster mushroom, abalone mushroom, and Ferula mushroom, the mycelium is pure white with strong wall-climbing ability; the mycelium is robust and vigorous; the substrate does not shrivel; aerial mycelium does not collapse; and when observed from the reverse side, there are no spots, streaks, or shadows except for the inoculation block point. For shaggy mane mushroom, the mycelium is grayish-white, sparser than that of oyster mushroom, and slightly earthy-yellow after maturation, with the inoculation block showing heavier pigmentation; the rest is the same as oyster mushroom. For straw mushroom, the mycelium is grayish-blue, greatly elongated, and semi-transparent, and after maturation most produce chlamydospores.

Sod culture increases soil aeration porosity and organic matter content
Sod culture offers many advantages, such as improving the soil environment and maintaining the orchard ecosystem. After it was promoted to farmers for adoption, many examples have confirmed the benefits of sod culture. However, before choosing a sod culture method, it is recommended to evaluate it from multiple aspects and select the sod culture method suitable for that farmland.
