A New High temperature Mushroom Variety of Edible Mushroom-Summer Mushroom 93
High temperature mushroom "Xia Mushroom 93" was selected in 1993 by researchers of Institute of Horticulture of Zhejiang Academy of Agricultural Sciences, which was originally named "Zhejiang AGh-1", which is suitable for summer cultivation. This variety fills the gap of mushroom cultivation in summer in China. The emergence period of high-temperature mushrooms coincides with the off-season of all kinds of edible mushrooms, the supply of fresh mushrooms is out of stock, and the price is 3-5 times higher than that in peak season. It has been promoted in more than 20 provinces and cities, such as Zhejiang, Jiangsu, Shanghai, Fujian, Guangdong, * and so on. The variety was identified in April 2000. Shengzhou Institute of Agricultural Sciences introduced this variety for trial planting in 1999 according to the climatic conditions of our city, and the planting mode of high temperature mushroom to autumn mushroom realized the dream of "one mushroom produces two seasons a year". The main features are as follows:
1. High temperature tolerance: the optimum temperature of mycelium is 24 ℃ ~ 36 ℃, the optimum temperature is 27 ℃ ~ 28 ℃, the suitable temperature for mushroom production is 25 ℃ ~ 34 ℃, and the optimum temperature for mushroom production is 27 ℃ ~ 32 ℃. It can continue to grow at 38 ℃ and can withstand the high temperature of 40 ℃.
2. High yield: 7.5kg / m2 to 15kg / m2.
Good mushroom quality: round mushroom shape, white, delicious taste, not easy to change color, resistant to storage and transportation, according to foreign trial marketing, can be refrigerated and kept fresh for more than 8 days.
4. Wide source of raw materials, simple cultivation and low investment: the main raw materials are rice and wheat straw.
5. The cultivation is roughly the same as that of Agaricus bisporus, which can be cultivated in the existing mushroom house, greenhouse or in the middle greenhouse in summer.

Mushroom planting: early prevention of mushroom "freaks"
Abnormal mushrooms are prone to deformed mushrooms when the ventilation is not smooth and the carbon dioxide content in the mushroom is more than 0.3%. The mushroom part is too deep, and the mushrooms that grow between the cracks in the coarse soil are often deformed. Attention should be paid to the ventilation of the mushroom room. The room of Pleurotus ostreatus and the surface of the culture material are not ventilated in time after spraying water, the humidity of the room is too high, small water droplets appear on the surface of mushroom, and rust spots will be formed over a long time. Therefore, the doors and windows should be opened for 30 to 60 minutes after each spray. The water spraying of Pleurotus ostreatus is too little, the overlying soil layer is dry, and the fruiting body is obtained.

Five methods to identify poisonous mushrooms
One is to look at the color. The color of poisonous mushroom noodles is bright, such as red, green, ink black, cyan purple and so on, especially purple, which is often highly toxic and easy to change color after picking. Second, look at the shape. The cover of non-toxic mushroom is flat, the umbrella surface is smooth, there is no wheel on the surface, and there is no receptacle in the lower part. The shape of the poisonous cap is strange, the surface of the bacteria is thick and hard, and the rods on the rods are slender or thick, and are easy to break. The third is to look at secretions. The non-toxic secretion is thick and reddish brown, and it is easy to change color in the air after being torn. The fourth is to smell. Non-toxic mushrooms have special fragrance, poisonous mushrooms are weird.
