A method for testing the deformation-responsive physical properties of flexible crops operated by airflow

Abstract

The invention discloses an airflow work flexible crop deformation response physical property test method. The method comprises the following steps of step1, selecting a type of a flexible crop which carries out airflow work and selecting a plot in an airflow work area as a test area used for physical property testing of the flexible crop; step2, collecting physical property data of the flexible crop; step 3, processing the physical property data of the flexible crop; step4, calculating a physical property test result of the flexible crop: and step 5: repeating the step 1 to the step 4 for multiple times, taking an average value of the physical property test results of the flexible crop as the final physical property test result of the flexible crop. By using the test method, a deformationresponse characteristic of the flexible crop under the airflow work can be accurately explored, and method guidance and technical specifications are provided for aviation spray airflow work.

Description

technical field [0001] The invention relates to a method for testing physical properties of flexible crops, in particular to a method for testing physical properties of deformation-responsive flexible crops for airflow operation. Background technique [0002] In recent years, with the advancement of agricultural mechanization and agricultural modernization, aerial plant protection technology has become more and more widely used due to its advantages of high operating efficiency, high pesticide utilization rate, and good control effect. Agricultural aerial spraying operations mainly use manned fixed-wing Aircraft, manned helicopters, single-rotor and multi-rotor UAVs are the main models. [0003] During the aerial plant protection spraying operation, due to the flight characteristics of the airframe, a strong downwash airflow will be generated. Under the action of the strong airflow, the sprayed flexible crops will produce different degrees of deformation response. For examp...

AI Technical Summary

Problems solved by technology

The physical property testing methods of flexible crops that can be queried are also relatively simple, all of which are unilateral physical property tests such as the growth period of flexible crops and the height of flexible crops. There is a lack of comprehensive testing and evaluation methods for the physical properties of flexible crops. Comprehensive testing and evaluation methods

As a result, the test results obtained cannot accurately characterize the physical properties of flexible crops, and cannot accurately explore the deformation response characteristics of flexible crops under airflow operations, which in turn has an impact on the droplet deposition effect of aerial spraying.
