Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings. The protection scope of the present invention is not limited to the following:

[0019] Such as figure 1 As shown, an irrigation forecast system based on an automatic water replenishment evaporating dish, which includes a water replenishment device 3, an evaporating dish 5, a measuring dish 8, a rain cover 15, and a central processing unit 9. A connecting pipe 12 is connected between the connecting pipe 12 and a valve a13 is installed on the connecting pipe 12. The evaporating dish 5 is located between the measuring dish 8 and the water replenishing device 3. An overflow pipe 6 is connected between the evaporating dish 5 and the measuring dish 8. The communication port between one end of the flow pipe 6 and the evaporating dish 5 is higher than the communication port between the other end of the overflow pipe 6 and the measuring dish 8. The diameter of the overflow pipe 6 is...

Abstract

The invention discloses an irrigation prediction system based on an automatic water supplementing evaporating dish. The irrigation prediction system comprises a water supplementing device (3), the evaporating dish (5), a metering dish (8), a rain cover (16) and a central processing unit (9); a communicating pipe (12) is connected between the water supplementing device (3) and the evaporating dish (5), a valve a (13) is installed on the communicating pipe (12), an overflow pipe (6) is connected between the evaporating dish (5) and the metering dish (8), and the rain cover (16) is installed at one side of the evaporating dish (5); the central processing unit (9) comprises a clock module, a processing module, a storing module, a weather forecast module, a program setting module, a communication module, a control module and a display screen. The irrigation prediction system has the advantages that intelligent control over evaporation capacity observation is achieved, and the observation precision is improved; the water demand of crops is predicted according to the observed evaporation capacity of the evaporating dish, and the crop irrigation schedule is made by combining a weather forecast system.

Description

Technical field [0001] The invention relates to the field of agricultural intelligent irrigation forecasting, in particular to an irrigation forecasting system based on an automatic water supplement evaporation pan. Background technique [0002] For irrigation forecasting systems, the most commonly used method is based on soil moisture, that is, the soil moisture content index in the root zone of the crop is used as the upper and lower limits of irrigation. This method has low efficiency and large errors. Water requirements are also different, and relying solely on soil moisture content to guide irrigation has certain limitations. [0003] The current irrigation forecast based on meteorological and soil moisture data also ignores the future short-term precipitation situation, which will cause precipitation when irrigation has just been completed or during irrigation, resulting in repeated irrigation. It not only causes a waste of water resources but also affects the normal growth ...
