1, the cultivation season. Purple fungus is a medium-high temperature type fungus. Can be arranged in the March-April cultivation bag, cultivate ear from May to May.
2, strain selection. Use strains with strong decomposition and anti-miscellaneous properties, strong mycelium, rapid growth, high quality and high yield, such as Caoyou 1x2. The original species required robust growth, high purity, and short fungus ridges.
3, ingredients bagging. Formula for cultivation: Grass clippings (crop stalks or weeds of various crops are comminuted into coarse wood chips, single or multiple combinations) 79%, bran (or rice bran) 10%, corn flour 5%, lime 3%, compound fertilizer 1.5 %, plaster 1%, æª0.5%. Mix the mixture and add water, so that the mixture moisture content of 60% -65%. Build a heap and ferment for 5-7 days (when the temperature rises to 60-65°C, turn 2-3 times). After bulk bagging, it can be bagged. The bag size is 15 cm x 40 cm.
4, sterilization, inoculation. Sterilize immediately after bagging. Can be steamed stove normal pressure (100-105 degrees Celsius) sterilization for 10-12 hours. After the pan is removed, when the temperature of the bag falls to 30°C, inoculate in the inoculation box (chamber) according to the aseptic procedure. Two inoculation methods were used to restore the seal while inoculating.
5, bacteria management. The inoculated material bags were moved into the house to be stacked neatly and protected from light. In April-April, the temperature was lower than the requirement for the growth of mycelia of purple auricular fungus. At this time, the temperature and temperature were taken to keep the temperature of the material at 26-28 degrees Celsius. After the mycelium is fully eaten, it is incubated at natural temperature. If the growth of mycelium is slow, a sterile needle awl can be used to make some micropores in the mycelial growth site to increase oxygen. After 30-45 days of culture, hyphae can be filled with bags. After 1 week, it was transferred to ear management.
6, ear field preparation. The ear can be selected in front of the house, in the garden or in the field, and in the field of vegetable fields. It requires cool ventilation, drainage and irrigation. If there is no natural shading condition, a 2m high sunshade should be built and the light inside should be “Sanyang Qiyinâ€. After the site is selected, according to the terrain preparation, dig a width of 1m to 1.2m, a depth of 0.15m to 0.2m, and an unlimited length, and open a drainage ditch around. Finally, the whole field spray insecticide sterilization drugs.
7, cover soil cultivation. Put the germ-infected material bag into the cocoon after unpacking, with a spacing of 2 cm. The bag gap was filled with sterile manure, covered with 2 cm thick sterile fertile soil, and covered with a film moisturizing. After 5-7 days, the hyphae can grow into the soil and drench it once. A few days later, there will be ear buds on the soil surface. At this time, we should control the temperature and humidity, and strengthen ventilation. Under suitable conditions, after 15 days, the ears are mature and harvested in time. After each tide was harvested, the water was stopped and kept for a few days, and then the water was top-dressed for the next tidal management. 4 consecutive ears can be harvested, and the cattle efficiency reaches 120%-150%.
