Detection system and method for deposition mass of aerially applied pesticide

Abstract

The invention provides a detection system and method for the deposition mass of an aerially applied pesticide. The detection system comprises an aerial sprinkling apparatus, a droplet collecting apparatus, a spectrum acquisition apparatus and a droplet deposition characteristic analysis apparatus, wherein the aerial sprinkling apparatus is filled with a pesticide application solution mixed with a fluorescent tracer and used for sprinkling the pesticide application solution to a preset area; the droplet collecting apparatus is a rollable continuous band-shaped medium laid in the preset area, having preset width and free of fluorescent effect, and the continuous band-shaped medium is used for collecting the pesticide application solution sprinkled by the aerial sprinkling apparatus; the spectrum acquisition apparatus is used for spectrum acquisition of the continuous band-shaped medium having collected the pesticide application solution; and the droplet deposition characteristic analysis apparatus is used for analyzing spectra acquired by the spectrum acquisition apparatus and calculating the deposition mass of droplet in the preset area. The detection system and method provided by the invention can conveniently acquire the deposition mass of the aerially applied pesticide.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a system and method for detecting the deposition quality of aerial pesticide application. Background technique [0002] In aerial spraying, the ground deposition characteristics of droplets (such as coverage, droplet size distribution, drift distance, etc.) directly reflect the quality of aerial spraying. In the application research of aerial spraying, the aerial spraying equipment and technical scheme are optimized mainly by obtaining and analyzing the information of the ground deposition characteristics of droplets. At present, the method of obtaining the ground deposition characteristics of aerial pesticide spray droplets mainly uses the method of laying water-sensitive paper on the ground (A portable scanning system for evaluation of spray deposit distribution, Computers and Electronics in Agriculture.76(2011): 38-43), Sampling the deposited droplets, and then using th...

AI Technical Summary

Problems solved by technology

Because the water-sensitive paper sample points (generally 76mm*26mm) are placed at a certain interval within the range of the spraying width of the aircraft, the deposition characteristics between the sample points are not detected, and the continuity of the deposition characteristic data is poor.

Although the lack of sampling discontinuity is made up for by reducing the spacing of water-sensitive paper and increasing the density of sample points, the cost of a single sheet of water-sensitive paper is relatively high (generally RMB 8-10 per sheet), and by increasing the density of sample points method will significantly increase the cost of the experiment

On the other hand, the method of increasing the sampling point density is still unable to obtain continuous surface sedimentary characteristic data in a complete sense

[0005] 2. The experimental process is cumbersome, takes up a lot of manpower and time, and is poor in convenience

After the experiment is completed, the water-sensitive paper is collected, the images of the water-sensitive paper are scanned one by one, and analyzed. The whole process is cumbersome and requires the cooperation of multiple people.

[0006] 3. The operation requirements are high, and data errors caused by misoperation are inevitable

Because water-sensitive paper is extremely sensitive to water and oil, it is necessary to wear rubber gloves during the experiment. A little carelessness will leave marks on the water-sensitive paper, which will directly affect the experimental data
