Common edible mushrooms include shiitake, straw mushroom, mushroom, monkey head, bamboo, pine mushroom (pine mushroom), lentinus edodes, and so on. Edible mushrooms such as shiitake are usually cultured by first sterilizing and inoculating shiitake spawn in bags, and then placing them in a culture chamber or greenhouse for cultivation. Watering shiitake is an essential operation during cultivation. Watering not only provides the necessary moisture for the growth and development of shiitake, but also increases the humidity in the air, maintaining the humidity in the mushroom pit stable, which is beneficial to the growth and development of shiitake.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present utility model will be apparently and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.

[0025] The fixed-point irrigation technology of shiitake mushrooms is an accurate and effective water management method, which aims to provide the most suitable moisture conditions for the growth of shiitake mushrooms by accurately controlling the position, time and amount of watering. Watering of shiitake mushrooms plays a crucial role in the cultivation process of shiitake mushrooms. First of all, water is an indispensable resource for the growth of shiitake mushrooms, which provides nutrients for mycelium and fruiting body and promotes the growth and development of shiitake mushrooms. By watering, the appropriate humidity of the culture medium and space can be maintained to ensure sufficient water supply for shiitake mushrooms during the growth process.

[0026] However, excessive or insufficient watering can have adverse effects on the growth of shiitake mushrooms. Excessive watering can lead to a lack of oxygen in the mushroom sticks, causing the mycelium to lose vitality and even leading to rotting sticks, which severely affects the yield and quality of shiitake mushrooms. In addition, excessive moisture can cause free water to remain on the surface of shiitake mushrooms for too long, resulting in spots and affecting the appearance and market value of shiitake mushrooms. On the contrary, insufficient watering can lead to a lack of water in the mushroom sticks, causing the mycelium to lose vitality, and the grown mushrooms to be smaller and fewer, which also reduces the yield and quality of shiitake mushrooms. Therefore, during the cultivation of shiitake mushrooms, the amount, time, and method of watering must be strictly controlled. Mushroom farmers should develop a reasonable watering plan based on factors such as the growth stage of shiitake mushrooms, weather conditions, and the moisture status of the culture medium.
