The fungus has wide adaptability, strong resistance, high yield, and easy promotion. The high-yield technology of woody fungus in woody bags in Henan Academy of Agricultural Sciences is as follows:

(1) Comparison of varieties with good varieties for many years proved that anti-pollution was best performed with Au897 and Hybrid 40, followed by yellow back fungus. The average biological efficiency was 137.68% for Au897, 114% for hybrid 40, and 123% for yellow back fungus.

(ii) For the medium-temperature varieties of the seasonal hairy auricularia, the optimum temperature for mycelia growth is 25-28°C, and the fruit bodies grow well in the 22-30°C range. According to the temperature conditions in Henan, the spring ear period should be in mid-May to mid-July; autumn ear should be in late August to the end of September. Different breeds have different ear temperatures. The suitable ear temperature of Au897 is 18-28°C, the hybrid 40 is 20-32°C, and the yellow-backed hair fungus is 24-35°C. Therefore, the arrangement production should be based on the characteristics of the variety.

(3) Ingredients: wood chips 78%, wheat bran 20%, sugar 1%, gypsum 1%, material-to-water ratio 1:1.4-1.6. Bagging, sterilization according to the conventional.

(4) Inoculate the material bag after sterilizing bacteria and germs. When the temperature of the material is reduced below 30°C, it can be transferred into the inoculation box. Inoculated under sterile conditions, the operation should be rapid and accurate. In order to reduce the pollution, the two-point inoculation method is adopted, and the amount of inoculum should be appropriately increased. In general, about 25 bags of each kind of bottle are used. Under suitable temperature conditions, hyphae can be fully bagged for 40-50 days.

(5) Hanging out of the bag To control the number of eared ears, the hanging ear of the fungus bag should be used for hanging ears (color chart 24). When the bag begins to grow from vegetative growth to reproductive growth, it must be hung in time. . When hanging, it is necessary to pay attention to the tightness of the bag mouth without leaving any gaps, so as to avoid excessive pores and bulkiness between the bacteria and the bag, resulting in air circulation, which will cause a large number of primordial differentiation and affect ear quality. After tying the mouth, hang the bags together, and then hang the tied bacterium bags on the bamboo frame and stagger the upper and lower bags. After the hanging, quantitative openings are made. The V shape is the best, and the mouth length is 1.5-2.0 cm. Open 8 and 12 mouths per bag.

(6) Ear management 1. Controlling ear temperature should be controlled at 22-30°C. Within this temperature range, ears should be heard, open films should be taken, and the color should be deep. If the temperature is too low, the ear buds are difficult to form. If the temperature is too high, the ear may be easily generated.

2. Note that moisturizing relative humidity should be maintained at 85 to 90%. When ear buds are cupped, the humidity should be increased to 90 to 95% to fully meet the ear bud growth requirements for water. At this time, the water spray should be mastered. The principle of fine spray, fine spray, air drying and multiple sprays, and less rainy days are used to ensure the normal development of the ear.

3. The fruiting bodies that increase the light fungus must be differentiated and developed under light conditions. In the environment of sufficient scattered light and partial direct light, the lugs are dark in color, and the meat is hypertrophic and of good quality. If there is insufficient light, the color of the ears is light and the quality is poor.

4. Ventilation and ventilation farms should pay attention to ventilation every day in order to develop the normal development of the ear. If the ventilation is poor and the concentration of carbon dioxide is too high, the development of the ear is affected, and bacteria are prone to appear.
