Problems solved by technology
[0004] The instrument developed based on nuclear magnetic resonance technology is used as a test equipment for seed oil content, and the superiority of its testing method has been recognized. However, the nuclear magnetic resonance instrument currently used in the field of corn selection and breeding cannot meet the actual application requirements. It is only used in scientific research units. adopted, and not effectively promoted outside scientific research units
Enterprise units in this field even use visual screening as a means of selection, and the inefficient selection work seriously hinders the cultivation of high-quality grain products

The invention discloses a nuclear magnetic resonance multi-channel detection system for rapid sorting of oil seeds. The multi-channel detection system includes a sampling system, multiple parallel weighing and sampling systems, multiple parallel nuclear magnetic resonance detection systems and multiple parallel Seed sorting system, the sampling system takes out multiple samples from the hopper containing the seeds and sends them to the parallel weighing and sampling system corresponding to the sampling system for weighing and sends them to multiple sets of parallel NMR at the back end The detection system performs detection respectively, and multiple sets of parallel seed sorting systems sort the seeds respectively according to the detection results of the nuclear magnetic resonance parallel detection system and guide them into containers of their corresponding categories. The present invention is used to realize the functions of multi-channel simultaneous sampling, weighing, sample introduction, detection, sorting, and sampling of seed samples, and realizes the multi-channel fast automatic sampling and sorting functions of seeds, making up for the traditional manual sampling method. Many defects of the method have greatly improved the detection and sorting efficiency of breeding.
Description
technical field [0001] The invention relates to a low-field nuclear magnetic resonance detection device, in particular to a nuclear magnetic resonance multi-channel detection system for rapid sorting of oil seeds. Background technique [0002] With the increase of population and the development of economy, the demand of corn keeps rising. The reduction of arable land and the deterioration of the environment have made people's demand for new varieties of maize with high yield, high quality and strong stress resistance increasingly urgent. Conventional breeding techniques have been increasingly unable to meet people's breeding needs. Haploid breeding is a relatively fast and efficient biological breeding technology. Then, it is very important to quickly screen out maize haploids and improve the accuracy of screening maize haploids. [0003] The oil content of corn seeds can be used as the basis for judging the selection of haploid and diploid seeds. The hydrogen-bonded lip...
