Water saving and control intelligent management method for regulating and controlling paddy field non-point source pollution

Abstract

The invention provides a water saving and control intelligent management method for regulating and controlling paddy field non-point source pollution. The method includes the following steps: a step 1, acquiring essential data of weather, water level, and soil moisture content of each paddy field area through an information acquisition device arranged in a paddy field monitoring area, and sending the acquired data to a wireless measurement and control module; a step 2, receiving the data through the wireless measurement and control module, and sending the data to a system analysis center; allowing the system analysis center to automatically operate a preset program to generate an open and closure control signal of an irrigation valve and a drainage gate according to the preset paddy field irrigation / drainage analysis program; and a step 3, allowing an intelligent controller to control open and closure of the irrigation valve and the drainage gate according to the signal received from the system analysis center, and sending the relevant essential data to a mobile phone monitoring terminal to perform manual control. The method can achieve regulation and control of output of paddy field non-point source pollution, can minimize non-point source nitrogen and phosphorus loss, and can achieve digital accurate control of water level depth of paddy field water-saving irrigation.

Description

【Technical field】 [0001] The invention relates to a water-saving and water-controlling intelligent management method for adjusting and controlling non-point source pollution in paddy fields, in particular to a method for realizing field water level regulation and minimizing the loss of non-point source nitrogen and phosphorus pollution by coupling field water level, ditch water level, soil humidity and rainfall information The intelligent management method of paddy field. The method can be applied to environmental monitoring and agricultural non-point source pollution prevention and control, and belongs to the technical field of non-point source pollution prevention and control. 【Background technique】 [0002] Agricultural non-point source pollution refers to the sediment, nutrients, pesticides and other pollutants in the farmland, which enter the farmland through surface runoff, soil inflow, farmland drainage and underground seepage in the process of precipitation or irriga...
