At present, there are many kinds of bamboo crickets, and there are more than ten species at home and abroad. However, due to the influence of conditions such as climate and environment, there are only a few species suitable for cultivation in northern China, such as long skirt bamboo poles, short skirt bamboo poles, and red bamboo poles. A suitable bamboo cultivation technique in the north.
First, cultivation
1. Raw material cultivation:
(1) Selection of raw materials: The raw materials suitable for the cultivation and growth of bamboo vines are quite broad, such as broad-leaved wood swarf, cotton seed hulls, crop straw, and bamboo.
(2) Raw material treatment: The selected raw materials are crushed to a final shape (such as sawdust) and treated in two ways. 1 lime water soaking. Use 0.3 to 0.5% lime water to soak the ingredients, stir them, and soak them in about 1 to 2 minutes; then remove and place them in the basket and rinse with water. The pH is around 7. Then control the raw material to a moisture content of about 65% to inoculate. 2 drug treatment method. The raw material is soaked with 1:800 times carbendazim or thiophanate solution to make the liquid higher than the slope. Take 2 to 3 minutes to remove the excess water, so that the water content can be inoculated around 65%.
(3) Cultivation method: First combine the cultivation room with formaldehyde and potassium permanganate. After the smoke disinfection treatment, apply a film on the cultivation box, put a layer of sandy soil, then a layer of material, a strain of bacteria, yellow 2 ~3 floors. Material thickness is about 25 cm, and usually 2 to 3 bottles of bamboo shoots are used for the first square meter. Wrap the plastic film after inoculation.
2. Clinker cultivation:
(1) Raw material treatment: Add 18% wheat bran or rice bran, corn flour 2%, urea 0.3%, calcium superphosphate 1.5%, sulfuric acid 0.3% to the selected raw material, mix with water and mix well to make the water content When you reach the hand, you can have water in your fingers.
(2) High-temperature sterilization: Put the mixed raw materials into an autoclave. When the temperature rises to 100°C, continue steaming for 5-6 hours and remove and place it in a pre-paved plastic film.
(3) Cultivation method: When the material temperature drops below 30°C, open the wrapped film, and insert the bacteria and then wrap the film.
Second, management
1. Ecological conditions:
(1) Temperature: The growth temperature of the bamboo mycelia is 25-32°C, and the optimum temperature is 23-24°C. The fruit body's growth and development temperature is between 15 and 28°C, and the most suitable temperature is 22 to 25°C. Above 32°C or below 5°C, the mycelium grows slowly or stops.
(2) Humidity: The hyphae growth humidity is between 60 and 70%. The bud's growth and development humidity is in the range of 75 to 95% of the wind. When breaking the ball and spreading the skirt, the relative humidity should be 85 to 95%, to 95. % is best, humidity less than 80%, the fruit body is difficult to form or deformed.
(3) Air conditions: Aphid is an aerobic fungus, and sufficient fresh air is required during the growth period of bacteria. Indoor ventilation and air exchange should be taken care of.
(4) Light conditions: Light has an inhibitory effect on the bamboo quail when grown, so no light is required for mycelium growth. The growth and development of fruiting bodies require scattered light.
(5) Nutritional conditions: The nutrients used in the growth of bamboo razor clams are mainly made up of carbon sources and ammonia sources, and inorganic salts and trace vitamins. The dead bodies of plants such as sawdust and straw are all the nutrients they need. In the stage of reproductive growth of bamboo worms, a little peat soil is needed.
2. Management method:
Within 3 to 4 days after seeding, the temperature should be maintained between 24 and 27°C. After a period of mycelial growth, when the hyphae of the medium is on the surface of the medium, it is covered with a layer of humus (3 to 5 cm thick). The soil used for flower cultivation). After the cover is placed, the air in the room is kept fresh, ventilation is needed every day, and the cover wet soil is kept. The temperature is kept at 22-24°C and the relative humidity is kept between 85-95%. Under normal circumstances, the development of mycelium 1 to 2 months, that is, hyphae extended to the soil surface, when the temperature is between 23 ~ 26 °C, the relative humidity is constant, given a certain amount of scattered light, and then after 5 to 10 days, the surface appears white spots It proves that the fruiting body is formed. When the fruit body grows and develops, the relative humidity should be 80 to 95%. It takes 40 to 80 days from bud emergence to maturity, which is determined by the temperature, the relative humidity reaches 95%, and the strength of the skirt is the greatest.
Third, harvesting and processing When the parachute skirt is completed and the spores are auto-dissolved, immediately harvest, remove the cap, fungus, and then dry treatment (sun, oven baking can be). After being made into dried products, they are tied into a bundle of 50 grams with a red string, sealed in a polyethylene non-toxic double-layer food bag, and put into a cylinder with a hygroscopic agent for sale.

Bamboo grasshopper, known as the "king of edible fungus" title, its delicious taste, rich nutrition, is the best-selling commodity in the international and domestic markets. According to the analysis test, bamboo worms contain eight kinds of amino acids that are essential for the human body. Long-term consumption can suppress blood pressure and reduce the content of cholesterol in the blood. It is a promising edible fungus.
