Testing method of fly maggotpoisson ratio

Abstract

The invention discloses testing method of a fly maggotpoisson ratio. The method comprises the following steps: setting testing environment conditions that the temperature is 20 to 30 DEG C and the humidity is 50 to 60 percent, shooting and recording speckle images of a mature living fly maggot before and after deformation through a CCD camera, obtaining grey fields of two differentdigital speckles after A / D conversion, performing certain correlation operation on the grey fields of two differentdigital speckles, meanwhile finding out correlation indexextreme points of the grey fields and corresponding displacement information and strain information, performing analytical processing on digital images, working out the displacement of an arbitrary point on the surface of the living fly maggot through related technologies, working out the values of the horizontal displacement and the vertical displacement of the living fly maggot, and finally obtaining the poisson ratio value of the living fly maggot. The methodcan make up technical deficiencies of traditionalpoisson ratiotesting method in terms of testing deformablemollusk insects, such as living fly maggots, and has very importantpractical significance in terms of agriculture and biological study.

Description

technical field [0001] The invention relates to the technical field of agricultural waste treatment, in particular to a method for testing the Poisson's ratio of fly maggots, which studies the dynamics of fly maggots by using livestock and poultry feces to breed fly maggots. Background technique [0002] my country is the largest pig-raising country in the world. Half of the pigs on hand in the world are raised in China. With the rapid development of my country's large-scale breeding industry, it has brought huge economic benefits. The ensuing livestock and poultry manure is harmful to my country's environment Huge pollution has been caused. Using solid livestock and poultry manure to breed fly maggots can not only solve the problem of environmental pollution, but also provide high-protein bait for the livestock and poultry breeding industry. Breeding fly maggots by using solid livestock and poultry manure is a very promising method to solve the environmental pollution caused...

AI Technical Summary

Problems solved by technology

Breeding fly maggots by using solid livestock and poultry manure is a very promising method to solve the environmental pollution caused by solid manure. However, when the fly maggots mature, it is a technical problem to separate the fly maggots from the solid manure. Methods such as separation and manual separation not only cause secondary pollution, but also consume a lot of human and financial resources.
