一、平菇要求什么样的生长条件?答:平菇正常生长的条件为:1.营养:平菇是一种真菌,所需营养靠培养料供给。其中以含碳物质最重要,其次是含氮物质和无机盐。碳源主要有糖类、纤维素等。氮源主要有氨态氮和有机氮等。此外,磷、钾、钙、镁、硫等矿物质也是不可缺少的元素。锯末、麸皮、谷糠、稻壳、秸杆、棉籽皮等,均可做培养料。其中以棉籽皮最佳。2.温度:平菇在各个生长阶段对温度的要求不同。菌丝生长的温度为4～35℃,最佳温度为24～27℃。15℃以下生长缓慢,可忍耐0℃低温。30℃以上生活力降低,40℃以上将会致死。子实体的形成及生长温度为5～24℃,最佳温度为10～18℃。10℃以下,子实体生长缓慢;20℃以上易出畸形菇或不生长。子实体属变温性结实。在一定温度范围内,昼夜温差越大,子实体分化越快。孢子形成温度范围为0～
First, mushroom growth requirements of what kind of conditions? A: The conditions for normal growth of Pleurotus: 1. Nutrition: Pleurotus is a fungus, nutrition required by the culture material supply. One of the most important carbon-containing substances, followed by nitrogen-containing substances and inorganic salts. Carbon sources are mainly sugars, cellulose and so on. Nitrogen sources are mainly ammonia nitrogen and organic nitrogen. In addition, phosphorus, potassium, calcium, magnesium, sulfur and other minerals are also indispensable elements. Sawdust, bran, bran, rice husk, straw, cottonseed skin, etc., can do training material. One of the best cottonseed. 2. Temperature: Pleurotus ostreatus in different growth stages of the temperature requirements. Mycelial growth temperature is 4 ~ 35 ℃, the best temperature is 24 ~ 27 ℃. Slow growth below 15 ℃, can tolerate 0 ℃ low temperature. Lower than 30 ℃ viability, more than 40 ℃ will be killed. The formation of fruiting bodies and growth temperature of 5 ~ 24 ℃, the best temperature is 10 ~ 18 ℃. Below 10 ℃, fruiting bodies grow slowly; Sub-entity is a warm and strong. Within a certain temperature range, the larger the temperature difference between day and night, the faster fruiting body differentiation. Spore formation temperature range 0 ~
