Condition control of temperature and humidity during fruiting stage of morels

1. The first is temperature control. Due to the large temperature difference between day and night in spring, it is beneficial to promote the growth of fruiting bodies. Not only that, the suitable temperature and heavy rainfall in early spring provide good conditions for the germination and growth of morel fruiting bodies. Morchella fruiting bodies can grow within 10℃~18℃, and the most suitable growth temperature is 12℃~15℃. When the temperature is lower than 10℃ or higher than 18℃, the growth of Morchella fruit bodies will slow down. The morel fruit bodies grown in the flat shed are unearthed quickly due to good air circulation.
2. In terms of illumination, light has a certain promotion effect on the formation of fruit bodies, especially in the development stage of fruit bodies, light plays an important role. During the growth and development of the fruit body, moderate scattered light is an indispensable condition for the production of high-quality morels. The phototropism of the fruit body tends to bend and grow in the direction of light. The intensity of the scattered light also has a certain effect on the color of the fruit body. The stronger the light, the darker the color, and the weaker the lighter the color. It is most appropriate to control the light at three points of sun and seven points of yin during the fruiting period.
3. During the fruiting stage, the relative water content of the soil should be controlled at 50%-70%, so that the morels can grow smoothly. In the management, pay attention to the control of two extreme humidity. One is that the relative humidity of the air is not less than 70%. If the air humidity is too low, the morel fruit body is empty, and the weight is light, the skin is thin, and it is easy to dry and crack, causing seeds. The entity stops growing, and for this, maintain a moist environment. The second is that the relative humidity of the air does not exceed 90%. If the relative humidity of the air is too high, the fruit body will be hypoxic. When spraying water, pay attention to a small amount and many times.
