A water and fertilizer variable control system and device for paddy field irrigation

Abstract

The invention discloses a water and fertilizer variable control system and device for paddy field irrigation. The system includes: a control body, including a main body pole, a support and a bracket connected in sequence, and the control body is arranged in the field to be irrigated and fertilized through the bracket; a water level sensor , set in the bracket, used to obtain water level parameters; database unit, set in the main body pole, used to obtain the required parameters; controller, set in the main body pole, the controller includes a memory and a processor, wherein the memory stores There is a computer program, and when the program is executed by the processor, the following steps can be realized: calculating the amount of irrigation according to the growth parameters of the crops, the parameters of the water quantity in the field and the area of ​​the paddy field; calculating the amount of fertilization according to the growth parameters of the crops, the parameters of the nutrients in the field and the parameters of the fertilizer. By implementing the invention, irrigation and fertilization can be performed on demand according to different crops, effectively avoiding the traditional decision-making of irrigation and fertigation by experience, and realizing 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...
