Experience of intercropping Rice and Auricularia auricula

Intercropping Auricularia auricula in rice growing season, the microclimate of paddy field can better meet the needs of fruiting body growth conditions, so the yield of Auricularia auricula can be increased by 1-2 times, and the yield per mu can reach 250 kg.

1. Temperature and humidity of auricularia auricula: Auricularia auricula is a medium-temperature edible fungus, the hyphae will not die in the environment of ±30 ℃, but the suitable temperature for development is 22-28 ℃, and the suitable temperature for fruiting body growth is 20-28 ℃. The suitable humidity for mycelium development is 60% Mel 75% (water content of bag material). Dampness causes poor ventilation and lack of oxygen, which affects the development of hyphae; when the humidity is too low, the mycelium dries up and stops growing. During the period of fruiting body growth, not only the bag material should have enough moisture, but also the air humidity should reach more than 90%. During the growth of Auricularia auricula, even if it rains all day, it has no effect on the growth of fruiting body.

Second, ear light: light can increase the temperature of the substrate, make the hyphae grow rapidly in the matrix, and enhance the color of Auricularia auricula, reduce diseases and grow strong. Auricularia auricula was planted in the middle of June and mid-September, when the temperature, humidity and light of the soil (water) of the paddy field were suitable to the physiological requirements of Auricularia auricula.

1. Select thermotolerant strain: the fruiting body of amber Auricularia auricula can still grow normally at 36 ℃. Therefore, it can be selected as a strain for production, and it is easy to be successful if it is intercropped in the high temperature season.

two。 The selection and preparation of rice field: choose the soil which is easy to precipitate after ploughing and easy to form into rice field after baking. Dig drainage ditches around rice fields and irrigate 1.6-3.3 cm for inclusion in bacterial rod intercropping.

3. Intercropping time: the bag material is made every spring, and the hyphae germinate after 40-50 days after sterilization, the hyphae are wound, and the whole bag is fluffy white; there is a strip out of the ear hole on the top of the bag material, which can be placed. The early rice field is about June 15, and the late rice field is about September 15. The prepared bacterial sticks are placed in the rice field.

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 avoid submerging bacterial sticks; at this time, it is necessary to drain the water layer and control the water layer so that it dries intermittently.

5. Harvest of fruiting body: when the edge of the ear piece becomes soft, the flesh is thick, and the ear shrinks or white spore powder is produced on the back, it shows that the ear piece is nearly mature or has matured, no matter whether it is big or small, it should be drained in time and harvested as soon as possible, otherwise it will rot and flow ear, affect the next stubble out of the ear, resulting in reduced production.
