Screening method of mildewed seeds

Abstract

The invention discloses a screening method of mildewed seeds, and belongs to the field of seed selection. A device comprises an ultraviolet fluorescent tube, a visible light single-color CCD (charge coupled device) sensor, a two-dimension grabbing mechanism, a single-layer seed conveying device and a control system, wherein the ultraviolet fluorescent tube, the visible light single-color CCD sensor, the two-dimension grabbing mechanism and the single-layer seed conveying device are electrically connected with the control system respectively. The autofluorescence characteristic of fungi is used, that is, to-be-processed seeds are irradiated by 356 nm ultraviolet rays, and the mildewed seeds are identified by detecting fluorescence excitation of the mildewed seeds under radiation of 356 nm ultraviolet rays. The method has the characteristics that the cost is low, industrialized screening of the mildewed seed is realized, and the demand of seed engineering for automatic production is met; the screening efficiency and the accuracy are higher, seed processing by an organic solvent and the like is reduced, and damage to healthy seeds is reduced, growth of the seeds cannot be influenced, environmental pollution is reduced, the cost is reduced and the like.

Description

[0001] This application is a divisional application with the original application number 2013103286434, the application date is July 31, 2013, and the invention title is "A Device and Method for Screening Moldy Seeds". technical field [0002] The invention relates to the field of seed selection, in particular to a method for screening moldy seeds. Background technique [0003] In the process of seed production, processing and storage, high temperature, high humidity or seed injury can lead to the invasion of fungal microorganisms and form moldy seeds. Among them, severe mildew is in the minority, and it is easy to identify as dark sclerotia. However, most moldy seeds have the appearance of healthy seeds and are difficult to detect. Once mixed with healthy seeds, in addition to the low germination rate of the moldy seeds themselves or no germination at all, it can lead to secondary infection of mold and affect the development of healthy seedlings. It can be seen that moldy...

Problems solved by technology

In the prior art, the identification of seeds needs to be identified one by one, or organic solvent treatment is required. These methods have low efficiency and accuracy, and organic solvents will also cause damage to the seeds to a certain extent, thereby affecting their germination.

[0005] Currently, there is no good solution
