Description

The invention relates to irrigated agriculture and can be used in the automation of irrigation by flooding rice systems.

The aim of the invention is to increase the yield by comprehensively assessing the factors that change the water temperature in the rice paddles.

This goal is achieved by maintaining flooding, which contributes to maximum heat accumulation under specific weather conditions.

The drawing shows an automated rice irrigation system.

The system consists of a water source 1 main and distribution channels 2, waste and drainage channels 3, rice checks 4, equipped with hydraulic automatic machines 5 water levels and microchips 6 equipped with hydraulic automatic machines 7 installation of discrete fixed water level in micro-chips 6, flow sensors 8 and temperature 9

waters whose outputs are connected to the input of microprocessor computing device 10.

The system works as follows.

The microcircuit water level regulators 7 keep constant various levels of microcircuit water from a minimum (for example, 5 cm) to a automated rice irrigation system, which includes that, in order to increase the yield capacity through an integrated assessment of factors that change the temperature of water in the checks, the system is equipped with control microcores from the flow sensor and the water temperature in them, set up by hydraulic automatic devices

maximum (for example, 30 cm). Signal - discrete fixed level

ly from the temperature sensors 9 and the flow sensors 6 of various micro-cells are fed to the input of the computing device, where the temperatures and water levels corresponding to them are analyzed. After analysis and calculation taking into account the temperature of irrigation water

in each of the micro-cages from the minimum to the maximum water level in the microchips, and by the microprocessor-based super-level command-forming device 40 in the checks connected to the flow and temperature sensors in the micro-cues.

and the existing level of flooding of checks 4, a command is issued to change the set point of automatic hydraulic machines 5. This selects the water level that provides the best accumulation of solar heat, taking into account specific meteorological conditions. After receiving the crew, the irrigators change the set points of the automatic hydraulic machines 5 in the paddy check 4.

The application of the proposed automated irrigation system allows the selection of the optimum water regime in checks, corresponding to the best accumulation of solar energy under specific meteorological conditions, and by increasing the amount of effective temperatures to increase rice yield by 3-5 centners / ha.
