Heat-resistant wild Pleurotus ostreatus np
The wild Pleurotus ostreatus was collected many times by the Institute of Biological soil Desert of the Chinese Academy of Sciences, and the pure strain was obtained after tissue isolation. Fruiting body primordia solitary or tufted, young primordia white or light brown. The cap is 10-12 cm in diameter and 1-1.5 cm thick. The cap is white or light brown. The flesh is white, the stalk is 1.5-2.5 cm in diameter, 2-6 cm long, and the color is white. The spores are white or lavender. It has wide adaptability and high temperature resistance. It can produce mushrooms under the condition of 30 ℃, but it can also produce mushrooms normally under the condition of 8 ℃.

A New Variety of Pleurotus ostreatus with Three High Quality---"2001"
"2001" is a new variety of Pleurotus ostreatus bred in 2002. It is proved by crystal ratio test and scale production that this variety has three outstanding characteristics: high resistance to yellow mushroom disease and rust spot disease, high yield and high efficiency. 1. High resistance to yellow mushroom disease, rust spot disease. "2001" belongs to the broad temperature type Pleurotus ostreatus. The fruiting body is pale white to gray white. It can produce mushrooms in the temperature range of 1--33℃. It is planted in large areas from early autumn to spring. In the occurrence area of yellow mushroom disease and rust spot disease,"2001" can be safely unharmed.

Cottonseed husks with plenty of cottonseed should not be directly used to grow Pleurotus ostreatus.
The cottonseed shell is composed of the shell left after the cottonseed is removed, the short cotton wool attached to the shell and a small amount of broken cotton kernels. Cottonseed hull is rich in nitrogen, phosphorus, potassium, cellulose and lignin, the ratio of carbon to nitrogen is 79-85:1, alkaline, outer pine and inner fruit, good air permeability and strong water storage, so it is the best raw material for edible fungus cultivation. However, cotton husk contains toxic substances, which will release aldehydes, ketones and acids after sterilization under high pressure or atmospheric pressure. these poisons will inhibit mycelium growth, delay budding, and cause adverse consequences such as small mushroom shape and poor mushroom quality.
