High-temperature mushroom cultivation techniques

The mushroom meat is fresh and delicious, and it is a kind of traditional edible mushroom variety that people generally like. However, the common mushroom variety is bifido mushroom. The mushrooming temperature is about 16°C, and it can only be seen on the market in autumn and winter and early spring season. The high-temperature mushroom species introduced in 1998 by Zhangjiagang City, Jiangsu Province for the Promotion of Edible Mushroom Technology, is a mushroom of the four species, which has a fruiting temperature of 26-31°C. The fruit body still grows well at temperatures as high as 26-38°C in July and August. , And to maintain a continuous batch production capacity, access to higher production, completely changed the history of the market without fresh mushrooms in the summer, and the mushroom farmers to cultivate mushroom production become a reality. The following is a brief introduction to the cultivation techniques of high-temperature mushrooms. 1 strain production 1.1 strains of high-temperature mushrooms Xindeng 96 cited from Hangzhou Evergreen Health Food Co., Ltd. Institute of bacillary dysentery. 1.2 The PDA medium is used as the mother of the culture medium, and the wheat culture medium is used for the original species and the cultivated species. The ratio is 98% of wheat grain and 2% of calcium carbonate. After bottling, sterilizing, inoculation, and cultivation, the finished product is made into a finished product. The strains are supplied to growers. 2 Cultivation techniques 2.1 Formulation of culture materials The conventional straw fermentation materials were used, and the specific formulation was (in terms of 111.1 m2 area): straw 2000 kg, cabbage cake 140 kg, superphosphate 100 kg, gypsum 100k, lime 75 kg urea 40 kg. 2.2 The composting fermentation of culture materials adopts secondary fermentation method, and it is piled outdoors for 15 days. It asks to turn it 3 to 4 times, and then enters the mushroom house or mushroom shed to warm it, and it is heated to about 65°C to maintain 6 After 8 hours, the temperature was lowered to 52°C for 3 days and post-fermentation was performed. 2.3 sowing and germination period management After the end of the second fermentation, open the doors and windows ventilation, when the temperature of the culture material is reduced to 30 °C, using the second sowing method. That is, first sprinkle 2/3 of the amount of bacteria on the surface of the material, then turn the bacteria into the material, and then sprinkle the remaining 1/3 of the bacteria on the surface of the material layer, gently pat the surface with a wooden board. The seeding rate is 2 bottles of wheat seeds or 3 bottles of cotton shells per square meter. After the sowing, the bacteria should be used to close the window. When the temperature is high, it can be properly ventilated. 2.4 Earth-covered soil When the mycelium grows to the bottom of the material layer, cover soil. Before covering the soil, it must thoroughly inspect whether there are latent bacteria and pests. Once it is found, measures must be taken to eliminate it before covering the soil. The earth-covered material is made of fine muddy soil or river muddy soil. The ratio of earthworm to earth is 20:1. Formaldehyde is used to disinfect before use, and the water is held in a pinch and spread, pH8 or so. The thickness of the cover soil is 3 to 4 cm. After the soil is covered, 2.25 kg/m2 of clear water is sprayed. Close the window and wait until the hyphae emerge in the crevice. 2.5 About 15 days after fruiting management, the hyphae begins to kink into the original base. At this time, ventilation and water spray are applied to keep the bed surface moist. When the bean sprouts appear in the earth seam, spray in time. Water promotes fruit body formation. At the same time, the mushroom house (mushroom shed) maintains high air humidity, reaching 85% to 90%. Throughout the cultivation and management process, it is necessary to properly handle the relationship between water spray, ventilation, and moisturizing. Mushroom harvesting should be timely, not too early or too late. 2.6 Insect pest control If insects are found in cultivation, brown spots appear on the surface of the mushrooms. After the end of a tidal mushroom, the enemy was killed by spraying 4mL of water and spraying 25kg of bed surface. Usually, a cotton ball with dichlorvos was hung on both sides of the aisle inside the mushroom shed to drive off the adult worm. At the same time increase the ventilation, so that the water does not accumulate in the mushroom body and cause discoloration and rot.
