Abstract

The invention belongs to the technical field of smart agriculture, and relates to a farmland intelligent irrigation forecasting system, which comprises an evaporation dish used for reflecting the plant evapotranspiration of a farmland; the remote signal controller is used for receiving the evaporation pan liquid level data measured by the liquid level meter and sending the received evaporation pan liquid level data to the monitoring terminal; the monitoring terminal is used for processing and displaying irrigation data; the automatic water replenishing device is used for replenishing water into the evaporating dish until the water surface reaches the initial mark position after the water surface in the evaporating dish reaches the irrigation mark position. The system has the advantages that automatic forecasting of farmland irrigation is achieved through design of automatic water replenishing, automatic observation, remote data transmission and the like, and important reference is provided for intelligent and accurate irrigation in intelligent agriculture.

Description

technical field [0001] The invention belongs to the technical field of intelligent agriculture, and relates to an intelligent irrigation forecast system for farmland. Background technique [0002] Plant evapotranspiration (Evapotranspiration And The, referred to as ET) refers to the total water consumption of farmland soil evaporation and plant transpiration. It is an important part of the farmland hydrological cycle and an important basis for guiding farmland irrigation planning and management. Studies have shown that a certain correlation can be established between ET and water surface evaporation, so water surface can be used to forecast crop ET. [0003] At present, water surface evaporation is mainly measured by evaporating dishes, and 20cm standard evaporating dishes have been widely used in farmland irrigation forecasting. Under field conditions, the water level in the evaporating pan will change due to evaporation. When the liquid level in the evaporating pan reache...
