A precision fertilization system

Abstract

James & Wells ref: 313600AU / 0 The present invention discloses a precision fertilization system. The fertilization system includes a sample injection device, a nutrient detection device, a control device, and a fertilization device, where the sample injection device, the nutrient detection device, and the fertilization device are all connected to the control device; the sample injection device is configured to absorb an injected sample solution and conduct reaction; the injected sample solution includes a nitrogen reagent, a phosphorus reagent, a potassium reagent, a nutrient solution, and a diluent; the nutrient detection device is connected to the sample injection device and is configured to conduct colorimetric analysis on the reaction solution to obtain absorbance; the control device is configured to control inflow of the injected sample solution in the sample injection device and wavelength adjustment of a light source in the nutrient detection device, and is further configured to calculate concentrations of fertilizers in the injected sample solution according to the absorbance and send a fertilization signal to the fertilization device according to the fertilizer concentrations; and the fertilization device conducts fertilization according to the fertilization signal. The present invention can implement in-situ, automatic, and rapid monitoring of nutrients, and conduct precision fertilization according to monitoring data of the nutrients.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a precision fertilization system. Background technique [0002] With the development of modern agriculture, the technology of water and fertilizer integration has been promoted rapidly. This technology saves water and fertilizer, and meets the requirements of national ecological civilization construction. Due to the increase in labor costs and the development of industrialized management of economic crops, fertilizer spreaders that are conducive to large-scale management and labor cost savings have developed rapidly. However, at present, the fertilizer applicator only monitors the EC value and pH value of the irrigation water or the fertilizer solution. The above two indicators cannot reflect the supply of specific nutrients, and have little guiding significance for precise fertilization, and the current fertilizers lack automatic detection-fertilization The feedback adjustment syste...

However, at present, the fertilizer applicator only monitors the EC value and pH value of the irrigation water or the fertilizer solution. The above two indicators cannot reflect the supply of specific nutrients, and have little guiding significance for precise fertilization, and the current fertilizers lack automatic detection-fertilization Feedback adjustment system cannot accurately control the amount of fertilization, which limits the development of precision agriculture
