Description

Technical Field

[0001] The present application relates to the field of agricultural production meteorology, and in particular to a soil moisture fixed-point monitoring device for agricultural meteorology. Background Art

[0002] Agricultural meteorology is closely related to agricultural production, and the growth of crops is inseparable from water. However, rainfall is an uncontrollable meteorological factor. There may be periods of time with little or no rainfall every year, such as from mid-July to mid-August every year. In addition, the high air temperature will cause the soil moisture to drop. When the soil moisture drops to a certain level, the crops will stop growing and even wilt due to water loss, which will eventually lead to reduced yields or even no harvest.
