Rice field irrigation water and fertilizer variable control system and device

Abstract

The invention discloses a rice field irrigation water and fertilizer variable control system and device. The system comprises a control body, a water level sensor, a database unit and a controller, wherein the control body comprises a main body upright tube, a support and a bracket which are sequentially connected; the control body is arranged in a farmland which is to be irrigated and fertilizedby the bracket; the water level sensor is arranged in the bracket and is used for acquiring a water level parameter; the database unit is arranged in the main body upright tube and is used for acquiring required parameters; the controller is arranged in the main body upright tube; the controller comprises a storage and a processor; the storage stores computer programs; and when being executed by the processor, the programs can implement the following steps of: calculating an irrigation amount according to a growth parameter of crops, a field water volume parameter and a rice field area; and calculating a fermentation amount according to the growth parameter of the crops, a field nutrient parameter and a fertilizer parameter. By implementing the rice field irrigation water and fertilizer variable control system and device disclosed by the invention, irrigation and fertilization can be carried out as required according to different crops, so as to effectively avoid a problem of conventionally carrying out irrigation and fertilization decision by means of experience and implement real-time on-demand irrigation and fertilization.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a paddy field irrigation water and fertilizer variable control system and device. Background technique [0002] With the development of modern agriculture, high-level automation equipment has played an increasingly important role in promoting the improvement of planting industry. At present, the rapid development of my country's agriculture relies on the extensive use of water, fertilizers, and medicines. This method has caused an increasing shortage of resources and caused serious environmental pollution problems. my country currently consumes a lot of water for agricultural irrigation, and the amount of chemical fertilizer used far exceeds the internationally recognized safety limit for chemical fertilizer application. The excess chemical fertilizer enters the ecological circle with the water flow, causing eutrophication of the water body, and leading to soil co...
