Intelligent sprinkling irrigation system with integration of water and fertilizer and control method thereof

Abstract

The invention relates to the technical field of irrigation, and discloses an intelligent sprinkling irrigation system with integration of water and fertilizer and a control method thereof. The systemcomprises a detection sub-system, a control sub-system, a fertilizer mixing sub-system and an irrigation sub-system, wherein the detection sub-system comprises a crop body sensor, a soil moisture content sensor and a soil fertility sensor; the control sub-system comprises a first receiving module, a calculation module and a comparison prewarning module; and the fertilizer mixing sub-system comprises a fertilizer mixing device. The method comprises the steps of system debugging preparation, information collection, actual demand calculation, water-fertilizer proportioning and irrigation. According to the system and method, the growing period of crops can be actively analyzed, fertilization and irrigation are provided by combining the regulation of water and fertilizer requirement of crops indifferent growing periods, abnormal growth of crops can be actively found, and administrative staff is informed; and after long time of use, pipelines of the irrigation sub-system are not easily blocked, the content of nitrogen, phosphorus and potassium of liquid remained after irrigation can be tracked, and reclaimed residual liquid does not need independent treatment during recycling, so that recycling can be convenient.

Description

technical field

[0001] The invention relates to the technical field of irrigation, in particular to an intelligent water and fertilizer integrated sprinkler irrigation system and a control method. Background technique

[0002] The water and fertilizer integration technology uses the existing water-saving irrigation system, uses the water of the system as the carrier, and at the same time irrigates the water, and at the same time, the fertilizer is blended into a fertilizer solution by an intelligent fertilizer applicator and transported to the soil in the root zone of the crops, so that it can be directly absorbed by the crops. Absorption; At present, it is widely used in the fertilization and irrigation of fruit forests, vegetables, flowers and other field agricultural crops. Residues, alleviate water pollution, in addition, can also save manpower and material resources, increase income. Intelligent water and fertilizer integrated irrigation uses computer technology on the...
