[0002] Soil humidity refers to the content of water in the soil, usually expressed by soil water content or soil relative humidity. In an agricultural greenhouse, soil humidity is one of the basic conditions for crop growth. It is related to the absorption and utilization of water by crops, and thus affects the growth and development of crops and the final yield. Compared with open-field cultivation, the soil humidity in an agricultural greenhouse is more easily controlled by humans. Through measures such as irrigation, drainage, and plastic film covering, the soil humidity can be precisely adjusted to meet the needs of different growth stages of crops.
