To control the growth speed of the ear, ensure that the ear length is dark and thick and round, no watering above 25 degrees, from 3 o'clock in spring afternoon to 9 o'clock the next day, watering from 5 o'clock in summer afternoon to 6 o'clock in the next day, all wet first Re-intermittent moisture management. Put down the film when watering, roll up for ventilation when not watering.
(1) Control of ear environment
1 Keep humidity
During earing, we should focus on humidification and coordinate the factors of temperature, air, and light. In particular, more water is needed during the differentiation of fruit bodies, and more attention should be paid to it. After opening the bags, the bags were sprayed with water for 1 time to make the bags wet and the ground was wet. The relative humidity of the air was maintained at about 90% to promote the formation and differentiation of primordia. Throughout the ear phase, the relative humidity of the air must be maintained above 80%. If the humidity is not enough, the hyphae of the shrinking parts will be easily degraded and decayed. Especially after ear buds are produced, the ear buds will be exposed in the air. When the relative humidity in the air is lower than 90%, the humidity is not enough and the ear buds are prone to losing water. Inflexibility affects ear differentiation. In order to maintain the humidity, it is best to lay large sand on the ground. Spray water or water directly on the surface of the ground, walls, and bacteria bags to increase the air humidity every morning, evening, and evening. When water is sprayed on the surface of the bacterial bag, water should be sprayed so that the ear does not wet the edge. The direct water spray on the ear should be minimized to avoid causing burned ears.
2 control temperature
The temperature of the earing stage is preferably 22°C-24°C, the lowest temperature is not lower than 15°C, and the highest temperature is not more than 27°C. Too low or too high temperatures will affect the growth of the ear and reduce the yield and quality. Especially in the case of high temperature, high humidity and poor ventilation conditions, it is extremely easy to cause mold contamination and ear damage. In the event of high temperatures, the key to management is to reduce the temperature as quickly as possible. The use of enhanced ventilation may be followed by spraying water and spraying well water around walls, space and the ground to reduce the temperature.
3 Increase lighting
Black fungus needs enough scattered light and certain direct light in the ear stage. Increasing the light intensity and lengthening the light time can strengthen the transpiration of the ear piece and promote its metabolic activity. The ear piece becomes hypertrophic, the color becomes black and the quality is good. Light intensity 400 ~ 1000lx is appropriate. Bags of black fungus, during the ear, should often switch and rotate the position of the bag, so that each bag can be evenly received light, improve the quality of fungus.
