A New method of cultivating Mushroom at High temperature

Mushroom is a kind of traditional edible mushroom which is widely loved by people because of its tender meat and delicious taste. However, the general mushroom variety is Agaricus bisporus, the mushroom temperature is about 16 ℃, and it is on the market in autumn, winter and early spring. The high temperature mushroom variety introduced and cultivated by Zhangjiagang Edible Mushroom Technical Popularization Station in Zhangjiagang City, Jiangsu Province in 1998 is Agaricus tetrasporus. The temperature of mushroom is 26 ~ 31 ℃. The fruiting body still grows well when the temperature is as high as 26 ~ 38 ℃ from July to August, and can maintain the ability of continuous batch production. The following is a brief introduction to the cultivation techniques of high temperature mushrooms.

① strain was made by strain. Choose high temperature mushroom Xindeng 96. ② medium. The mother seed uses PDA medium, the original seed and cultivated seed use wheat grain medium, wheat grain accounts for 98%, calcium carbonate accounts for 2%, and the finished strain is made after bottling, sterilization, inoculation and culture.

Cultivation technology ① culture material formula. Using conventional rice straw fermentation material, the specific formula is as follows: 2000 kg of rice straw, 140kg of vegetable cake, 100kg of calcium superphosphate, 100kg of gypsum, 75kg of lime and 40kg of urea. Heap fermentation of ② culture material. Using the method of secondary fermentation, the fermentation was made outdoors for about 15 days, during which the pile was turned for 3 or 4 times, and then went into the mushroom room or shed to heat up to 65 ℃ and kept for 6 hours for 8 hours, and then lowered the temperature to 52 ℃ for 3 days for fermentation. Management of sowing and sporulation period of ③. After the second fermentation, the doors and windows were opened for ventilation, and the twice sowing method was used when the temperature of the culture material dropped to 30 ℃. That is, first sprinkle the amount of bacteria on the surface of the material, then turn the bacteria into the material, then sprinkle the remaining 1 of the bacteria on the surface of the material layer, and gently pat it flat with a plank. The sowing rate is 2 bottles of wheat seeds or 3 bottles of cotton husks per square meter. After sowing, it is mainly to close the window to send bacteria, and it can be properly ventilated when the temperature is high. ④ cover soil. When the hyphae basically grow to the bottom of the material layer, cover the soil, before covering the soil must thoroughly check whether there are latent bacteria and pests, once found that measures must be taken to eliminate them before covering the soil. Fine mud bran soil or river mud bran soil was used to cover the soil. The ratio of rice chaff to soil was 20 ∶ 1. Formaldehyde was sprayed before use. The thickness of the covered soil is 3cm. After covering the soil, 2.25 kg of water is sprayed per square meter. Close the window and fill the soil when mycelium emerges in the gap of the soil layer. ⑤ mushroom management. About 15 days after covering the soil, the hyphae began to kink into primordia, and ventilation and water spraying should be carried out at this time to keep the bed surface moist all the time. When soybean-sized mushroom buds appear in the soil seams, spray water in time to promote the formation of fruiting bodies. At the same time, the mushroom house (mushroom shed) to maintain a high air humidity, generally 85% to 90%. In the whole process of cultivation and management, the relationship among water spraying, ventilation and moisturizing should be handled correctly. Mushrooms should be harvested in time, neither too early nor too late. ⑧ pest control. If there are insect pests in cultivation, yellowish-brown spots will appear on the surface of mushrooms. After the end of a tide of mushrooms, use the enemy to kill 4 milliliters and 25 kg of water to spray the bed. Cotton balls dipped in dichlorvos can be hung on both sides of the aisle in the mushroom shed to drive away adults. At the same time, it is necessary to increase ventilation so that water does not accumulate in the mushroom body and cause discoloration and rotten spots.
