AI Technical Summary

Technical Problem

Existing wheat breeding equipment has several problems during the sampling process, including cross-sample contamination caused by organic residues on the blade surface, in-situ markers on plants being susceptible to detachment and failure due to environmental stress, and the separation and breakage of the data traceability chain between ex vivo samples and field parent plants.

Method used

An integrated device for precise sampling and labeling of single wheat breeding materials is employed, comprising a feeding drive mechanism, a photoacoustic coaxial punching and in-situ labeling module, a carrier-type encapsulation and collection system, a microfluidic liquid supply and pneumatic auxiliary system, and a central timing master control and data interconnection system. The photoacoustic coaxial punching and in-situ labeling module enables high-frequency mechanical vibration cutting of plant tissues and ultraviolet beam irradiation, while the microfluidic liquid supply system and data interconnection system enable in-situ crosslinking and data binding of the markers.

Benefits of technology

It achieves pure cutting of plant tissues, avoids marker shedding, ensures the consistency and traceability of breeding data, and solves the problems of cross-contamination and broken data traceability chains.

Abstract

The invention relates to the technical field of agricultural breeding, and discloses a wheat breeding material single plant accurate sampling and marking integrated device which comprises a feeding driving mechanism, a photoacoustic coaxial punching and in-situ marking module, a carrier band type collecting system, a micro-fluidic system and a central main control system. A tool edge is prevented from contaminating a sample in combination with a cavitation effect; a sample is cut off and falls into a carrier tape to complete closed packaging and digital reading, a module pumps liquid photosensitive resin to a plant wound surface, the resin is promoted to deeply permeate through ultrasonic induced shear thinning and an acoustic streaming effect, ultraviolet light beams are coaxially output for in-situ curing, and an anti-stripping mechanical interlocking mark patch is formed. And the master control system extracts a sample identifier, a timestamp and a quantum dot spectral feature in the resin, and generates an encrypted hash value for persistent storage. According to the invention, high-purity accurate sampling, stable in-situ marking and tamper-proof multi-dimensional data traceability are realized.
