Formulation of original species and cultivars: wood chips or cottonseed hulls 76%, wheat husk 20%, sugar 1%, lime powder 2%, superphosphate 0.3%, urea 0.3%, potassium dihydrogen phosphate 0.3%, magnesium sulfate 0.1% The feed water ratio was 1:1.2 and the pH was 5.5-6. After the ingredients are mixed, they are bottled, and they are required to be loosened and slightly smashed in the middle. They are then sterilized under a pressure of 1.5 kg/cm2 for 2.5 hours, and the medium can be inoculated when cooled to 25°C. °C Ventilated dark culture chambers can be used for expansion and cultivation after 70-80 culture.
2ã€Cultivation season and place selection Red razor clams are required to grow under partial yin and damp environment. The cultivating place should be selected in the area of ​​500-1000 meters above sea level. The time is appropriate from February to May and September to November. The most suitable temperature is At 20-26 °C.
Indoor cultivation using underground or scaffolding two ways, the cultivation of 2-3 layers is appropriate, each layer height 60 cm, width 1.3 meters. In the outdoor areas, the shady areas, fertile soil, and semi-sandy acid fields are also available. No sandy soil is acceptable, but it is necessary to cover humic soil and sandy soil. The cultivation site should also be covered with a shade shed that is nearly 2 or more meters in height.
3, the preparation of culture materials and the processing of perishable materials will cause the lack of nutrients in the broth of red razor clams, which will cause budding and death buds. Therefore, the culture materials require fresh and dry materials. The best processing of wood is 10-12 cm long. Mixed bamboo and bamboo pieces can be cut into 50 cm long and used after fracturing. The proportion of bamboo material in the culture material should be more than 30%, but bamboo silk and bamboo shavings should not be used because of poor water retention. Before the seed is seeded, it shall be immersed in 5% lime for 6-7 days before it is soaked, then rinsed with clean water for 2 days, and then the pH shall be lowered to 6-6.5 before being picked up. Fermentation method can also be used to make the raw material soaked in water and piled into a 1.2-meter-high, 2-meter-wide fermenter, covering the film. When the central temperature reaches 65°C, the soil is turned over. Generally, the soil is turned every 7 days until the raw material is ripe and brown. It can be used without ammonia smell.
4. Cultivation methods Spraying 1000 times of methamidophos pesticide solution plus 30% formaldehyde for 10 days before sowing disinfests the cultivation site. Two to three days before planting, the soil in the pasture was made into a boring machine with a height of 50 cm and a width of 1.3 m. When sowing, mix the unfermented culture medium with 4-6 cm thick, then broadcast the strain, then spread 8-10 cm culture material, re-spread the bacteria, and spread the second layer 2-4 cm thick, ie cover with humus soil 4-6 cm, humus soil must be sterilized before sterilization, the soil moisture content does not dry or wet. After that, cover with 2 cm thick bamboo leaves, thatch or pine needles, and finally cover the membrane to incubate moisturizing bacteria. The use of dry material 20-25 kg per square meter, strains of 3-4 kilograms, the required species during the sowing process is not broken and strict light.
5. Scientifically control the moisture content of the culture material after sowing at 65%-75% and the relative humidity of the air is 85%. It is not necessary to spray water for the first 15 days. After 7 days, the membrane is ventilated for 30 minutes every 3 days. When the temperature exceeds 30°C, the membrane should be removed and covered at night.
After sowing at normal temperature for 50 days, the strains grow out of the soil surface, and the humidity should not be increased so that the surface of the mask is dried. After the mycelium is covered with the surface, the humidity of the surface is reduced to make the mycelium dry and fall into the culture medium. Continue to absorb nutrients, 70-80 mycelium covered the entire material surface. At this time, spray a heavy water again, so that the water does not leak into the culture medium, the membrane is opened at night, and the membrane is covered the next morning so that the temperature difference between day and night can reach 10° C., and the water should be sprayed after the surface soil is slightly dry. The first tidal mushroom can grow 60-80 mature eggs per square meter. After mushrooming, the relative humidity in the membrane is kept at about 85% and the temperature does not exceed 34°C, so that the bacteria eggs develop in a suitable temperature and humidity environment. .
Ventilate for 1-2 hours per day. Remove the film if it exceeds the temperature. After 30-35 days, the bacteria and eggs have entered maturity, and the transverse tip of the peach is pointed and raised. During this period, more water is sprayed. The amount of water is not subject to leakage, and the relative humidity of the air is increased to 90%-95%, which is conducive to fruit body differentiation. The time required for the rotifers to break eggs and spread the skirts is usually at 9:00 pm. The next day, the next day, the 3-4 skirts are completed. A small amount of the skirts should be sprinkled in the daytime and should be harvested and dried in a timely manner and packaged for sale.
After the first tidal mushroom is finished, it should make up the original moisture of the culture material and soil and continue to manage the mushroom. Water management methods are multi-mushroom and multi-spray, fewer mushrooms and less spray, high-temperature drying and more spray, low temperature and high humidity, spray less, spray or not spray in rainy days.
1. Selection and production of strains At present, there are many varieties of red brackets cultivated by artificial domestication in China. It is advisable to use fine varieties with rapid germination, early fruiting, high yield, and high dry taste, and they should also be selected for inoculation. Years can be harvested for 2-3 years.
