1. Artificial cultivation techniques of termitomycetes;
1, seasonal arrangement
When the temperature is stable at 12℃-24℃ or higher, it is the best bagging season and the best temperature range. At this time, inoculation does not need heating, and the survival rate is high. After 40-50 days of culture, mycelium covers the bag. When the temperature rises, the bag will be buried in the soil, and the first batch of mushrooms will soon grow. Autumn will last from September to 10. During this period, termites were active, but did not cause harm. When edible fungi are shredded, some substances that are beneficial to the growth of Pleurotus ostreatus are secreted to promote the growth of mycelium and achieve high yield.
2. Preparation of culture medium
Sealing formula: sawdust 75%, bran 20%, gypsum 1.5%, sugar 1%, termite nest soil 3%, water 140%.
Preparation method: Weigh the ingredients, then turn them into an even mixture, and check whether there is water after stacking for 2 hours. The water content is about 65%, that is, the water droplets formed between the hands grasping the culture do not fall.
Bagged inoculation: polypropylene bag filled 17× 45cm, and no cotton bag on the back of two sets of collars. Sterilization and inoculation are carried out as usual.
3. Fungal culture
Put the inoculation bag into a pre-sterilized culture room. Adjust the bag temperature between 20°C and 25 c. Normal mycelium is cultured for 40-60 days.
4, outdoor scaffolding
After the mycelium of termitomyces gallinarum is physiologically mature, it should be moved to the field mushroom shed, and the site with north-south orientation, flat terrain, fertile soil and acidity should be selected. You can also use the yard in front of the house as a training place. Make it into a bed, the width is 0- 100 cm, and the length depends on the site. Dig out the topsoil and shape it into a concave border of 15 cm. Chicken termites like acidic environment, so it is not suitable to sprinkle lime powder for disinfection, but appropriate amount of carbendazim or thiophanate can be sprinkled. Sprinkle coarse sand with an average thickness of 3-5 cm on the bed, and dig drainage ditches around it. The mushroom shed is 2 meters high, and the upper part and periphery are covered with grass curtains.
5. Cultivation management
When nail-shaped or coral-like tumor spots with the size of rice grains appear on the wall of the fungus bag full of hyphae, the tube membrane of the fungus bag is removed, and the fungus bag is placed in a frame with width of 60cm and depth of 25cm and unlimited length, the distance between the fungus sticks is 2-3cm, the gap is filled with land information, and the fungus sticks are covered with fertile soil or saprophytic soil in the vegetable garden with a thickness of 8 8- 10/0cm. After 30 ~ 40 days of culture, the fruiting body of termitomycetes can break through the ground.
6. Mushroom management
The fruiting time of termitomycetes is generally from June to 65438+1October in summer and autumn. The temperature should be controlled at 24℃-28℃. When the temperature is high, the roof of the shed will be shaded by thickening, and shallow water will be poured into the furrow, and water will be sprayed into the shed space in the morning and evening to artificially create a cool and humid environment, and the relative humidity of the air is 85% ~ 90%. It also widened the temperature and humidity difference between day and night, and promoted the improvement of mushroom quality. Ducklings often bite mushrooms during the period of fruiting, which can be captured manually.

Nutritional components of termitomycetes:
Chicken? Mushroom chicken? It is rich in nutrition, especially in protein. Protein contains more than 20 kinds of amino acids, 8 of which are essential for human body. China has praised termites and chickens for generations. Bacteria are full of beauty and rich nutrition. According to the analysis, every100g of fresh chicken? The water content of bacteria is 92.6 1%, and the dry matter is 7.39%. The dry matter contains crude protein 34.94%, crude fat 3.40%, crude fiber 13.9 1%, soluble sugar 4.5%, hydrolyzed sugar 9.59% and ash 7.73%. The ash contains 20.29% calcium oxide, 4.62% phosphorus, 0/.89% iron/kloc and 0.08% manganese. It also contains ergosterol, 16 amino acid and vitamin C.
Chicken? With high medicinal value, modern medical research found that chicken? Contains effective ingredients for treating diabetes, and has obvious effect on lowering blood pressure.
