First, the ear temperature and humidity: black fungus is a medium-temperature edible fungus, mycelium will not die in the environment at 30 °C, but the development of a suitable temperature of 22-28 °C; the appropriate temperature for fruit body growth is 20-28 °C . The suitable humidity for hyphae development is 60%-75% (water content of bag material). Humidity is too high to cause poor ventilation, lack of oxygen, affect the development of mycelium; humidity is too low, mycelium is dry, and stop growing. During the growth of fruit bodies, not only should the bags have sufficient moisture, but also the air humidity should reach more than 90%. When the fungus grows, even if it rains all day, it has no effect on the growth of fruit bodies.
Second, the ear illumination: light can increase the temperature of the substrate, so that the rapid growth of mycelium in the matrix, and can make black fungus enhance the color, reduce disease, grow strong. In the middle of June and mid-September, black fungus is interposed between rice and rice. At this time, the temperature, humidity and light of the earth (water) temperate rice and rice fields of the rice fields are compatible with the physiological requirements of the fungus.
1. Select temperature resistant strains: The fruit body of amber brown fungus can still grow normally at 36°C. Therefore, they can be selected as production strains and interplanted in the hot season.
2. Selection and Preparation of Rice Fields: Soils that are easy to be settled after being leveled by farming, and that are easily plated into rice plants after being field-baked. Drainage ditch around the rice field, irrigation 1.6-3.3 cm, ready to be included in the bacteria bar nest.
3. Interception time: Each year, the bag material is produced in spring. After germination, the mycelium is germinated in 40-50 days. The mycelium is entangled and the whole bag is velvety white. There is a bar-shaped ear hole above the bag material, and then the nesting can be performed. place. On Waseda, around June 15th, late rice fields set about 15 September, and put their prepared rods in the middle of the day.
4. Water management: If there is a hidden water source in the paddy field, it is necessary to prevent the water layer from being too high and to avoid submerging the mycelium. At this time, the water should be drained and the water layer should be controlled so that it can be dried intermittently.
5. Harvest of fruiting body: When the edge of the ear becomes soft, the flesh is hypertrophic, and the ear is to contract or produce white spore powder on the back, it means that the ear is nearly mature or mature, and the size should be promptly drained and collected early. Otherwise, it will cause bad ears and ears, affecting the ear, resulting in reduced production.
Rice - black fungus
During the growing season of rice, black fungus was planted. The microclimate of paddy fields can meet the requirements of fertility conditions of fruiting bodies. Therefore, the yield of black fungus can be increased by 1-2 times and the yield per mu by 250 kilograms.
