Description

Technical Field

[0001] The utility model relates to the technical field of agricultural drip irrigation, in particular to an automatic drip irrigation control device. Background Art

[0002] Drip irrigation is a combination of irrigation tools used in drip irrigation technology, and the drip irrigation water and fertilizer device is a device used for irrigation. Drip irrigation equipment uses a pressure system or natural terrain drop to mix soluble solid fertilizer or liquid fertilizer according to the soil nutrient content and crop fertilizer requirements into a fertilizer liquid. The fertilizer liquid is evenly dripped into the soil near the roots of the crops through pipes laid in the field along with the irrigation water.

[0003] However, existing greenhouses often use independent watering and fertilizing methods, resulting in uneven fertilization and irrigation. This results in low automation and relies on extensive manual operations. People often irrigate crops based on habit, such as when leaves droop or soil is dry. These habits are often difficult to capture with data, making precise irrigation difficult. To improve water use efficiency and reduce labor time, an automated drip irrigation control system is essential. Utility Model Content
