Rapid nondestructive testing method for male and female silkworm pupas based on spectrum technique

Abstract

The invention relates to a rapid nondestructive testing method for male and female silkworm pupas based on a spectrum technique. The rapid nondestructive testing method comprises the following steps: (1) selecting different types of silkworm samples, and carrying out spectrum scanning; (2) after the spectrum scanning, carrying out cocoon-breakage male and female detection on the silkworm samples; (3) constructing an optical model of silkworm cocoon sample; (4) constructing a spectrum collection module, and carrying out spectrum collection; (5) separating a collected spectrum; (6) preprocessing the separated spectrum, extracting a characteristic wavelength, and establishing a discrimination model of a single-source spectrum; and (7) carrying out multi-source information fusion, so as to obtain a nondestructive testing result of the genders of the silkworm pupas. Based on existing researches of reference data mining, an optical technique, a spectral analysis technique, a computer technique and sericultural science, the nondestructive testing is carried out on the male and female silkworm pupas in cocoons based on Raman, fluorescence and near infrared spectrum multisource information fusion by virtue of a combined method of theoretical analysis and experimental verification; and the method has the advantages that the detection accuracy is high, the detection speed is high, the silkworm pupas are not injured, and the like.

Description

technical field [0001] The invention relates to the technical field of male and female identification of silkworm chrysalis, in particular to a rapid non-destructive detection method for male and female silkworm chrysalis based on spectrum technology. Background technique [0002] Silkworm chrysalis male and female identification technology has important economic significance for both silkworm egg production and silk production. The male and female identification technology of silkworms has always been a difficult problem that sericulture workers want to solve. In the process of breeding new varieties of sericulture and producing silkworm eggs, it is necessary to separate the male and female silkworm chrysalis of different strains for hybridization. According to incomplete statistics, the number of silkworm chrysalis identified manually every year in the whole country is as high as billions, which not only wastes a lot of manpower, material resources and time, but also is p...
