What are the new high-yielding varieties of Pleurotus ostreatus

There are many varieties of Pleurotus ostreatus in production, such as Pleurotus ostreatus No. 1, Xin 831, Qingfeng 1, Jiangdu 109, Garden 802 and so on. These varieties have a certain influence among the majority of mushroom farmers, and some mushroom farmers often do not change varieties for several years because they prefer a certain variety. This is not necessarily beneficial to the realization of high yield of Pleurotus ostreatus, because the long-term use of a single variety may lead to variety degradation, such as the decrease of variety resistance and yield, thus affecting the benefit of growing mushroom.

More new varieties of Pleurotus ostreatus have been introduced in recent years. Through experimental comparison and practical verification, the following varieties are of great value in popularization and utilization.

The mycelial growth temperature of ① 50596 was 8 ℃ ~ 32 ℃, the temperature of mushroom production was 6 ℃ ~ 30 ℃, and the optimum temperature was 12 ℃ ~ 26 ℃. The mushroom body is clustered, gray-white, the diameter of the cap is 615cm, the handle length is 2cm, the mushroom quality is good, and the tide turns quickly. But it is easy to cause long handle in low temperature season.

The growth temperature of ② Nanjing No. 1 mycelium is 6 ℃ ~ 32 ℃, the temperature of mushroom production is 6 ℃ ~ 30 ℃, and the optimum temperature of mushroom production is 8 ℃ ~ 25 ℃. The fruiting body is dark gray, dark gray in low temperature, clustered or superimposed in fruiting body, compact mushroom shape, 5-10 cm in diameter, thick stalk and cap tissue, strong toughness and good quality.

The suitable temperature for mycelium growth of ③ Heigongyan No. 1 is 10 ℃ ~ 28 ℃, and the suitable growth temperature for fruiting body is 6 ℃ ~ 26 ℃. The cover surface is dark gray-black, clustered or superimposed, short stalk, fine mushroom, water and transport resistance, and high yield.

The suitable temperature for fruiting body development of ④ Qingfeng 518 is 8 ℃ ~ 25 ℃, the fruiting body is clustered or superimposed, the surface of the cap is dark gray, the stalk is short, the mushroom is concentrated, and the resistance to impurities is strong.

⑤ Hokkaido No. 3 mycelium development temperature is 20 ℃ ~ 26 ℃, fruit body development and growth temperature is 6 ℃ ~ 25 ℃, fruit body superimposed. The surface of the cover is brown, the fold is compact, the cover is thick, the mushroom quality is excellent, and the yield is high.
