Title:
UNMANNED AERIAL VEHICLE ACCURATE VARIABLE-RATE FERTILIZATION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/077760
Kind Code:
A1
Abstract:
The present invention relates to the technical field of crop production. Disclosed is an unmanned aerial vehicle accurate variable-rate fertilization method. The method comprises the following steps: S1: selecting a crop test area for unmanned aerial vehicle accurate variable-rate fertilization; S2: designing a crop test plan for unmanned aerial vehicle accurate variable-rate fertilization; S3: parsing the test plan in step S2 by means of an unmanned aerial vehicle accurate variable-rate fertilization system; and S4: performing, by means of test parsing obtained in step S3, extended analysis on a fertilization amount required by a crop in a key growth duration during growth. Therefore, the problems, which still remain in wheat production, of a fertilization method being unscientific, the fertilizer efficiency being low, the utilization rate of a unit dose of fertilizer not being high, etc. are solved. In the present invention, the characteristics of maneuverability, flexibility, high spatial resolution, etc. of unmanned aerial vehicle remote sensing in terms of crop production management are used, and on the basis of nutrition diagnosis of nitrogen fertilizer for winter wheat, a topdressing recommendation model for winter wheat in key growth periods such as a regreening period and a heading period is established according to a spectrum-diagnosis-based fertilization model, thereby achieving precise management of nitrogen fertilizer for winter wheat.
