Abstract

The invention discloses a system and method for rice field aeration irrigation and drainage simulation control. The system comprises a simulated rice field device, a controller, a reservoir, a water collecting tank, a water level sensor, a humidity sensor, a dissolved oxygen sensor and an air adding pump. The simulated rice field device is an uncovered container containing soil; an air adding pipe is arranged in the soil of the container; the air adding pipe is connected with the air adding pump outside the container; and the air adding pump is controlled by the controller. The reservoir is connected with the simulated rice field device through a water inlet pipe, and the water inlet pipe is provided with a first solenoid valve. The simulated rice field device is connected with the water collecting tank through a drain pipe, and the drain pipe is provided with a second solenoid valve. The water level sensor, the humidity sensor and the dissolved oxygen sensor are connected with the controller. The system further comprises a drainage reutilization mechanism which mainly collects return water of a rice field through a channel and collects the return water to the water collecting tank so as to sustainably utilize irrigation water, and the problem of difficulty in water transfer in a mountainous area during the drought is solved. The system is simple and efficient and has a huge promotion potential.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a simulation control system and method for paddy field oxygenation irrigation and drainage. Background technique [0002] Rice is in a waterlogged or nearly saturated water state for a long time, so that the soil in the root zone is mostly in a reduced state, which will lead to the enrichment of reducing substances. Although the rice root system has oxygen secretion, it will also appear black roots and other phenomena, which will affect the rice. Root growth. Aerated irrigation can improve the gas environment in the root zone, promote crop growth, increase root activity, increase water and fertilizer utilization efficiency, improve crop yield and quality, and achieve high efficiency, high yield and high quality. Insufficient oxygen supply in conventional irrigation of rice leads to a decline in various indicators of the root, which becomes the target of microbial bacteria and p...
