Description

System for detecting vitality of corn seeds Technical Field The invention belongs to the technical field of seed quality detection equipment, and particularly relates to a system for detecting the vigor of corn seeds. Background Seed vigor is an important index of seed quality, and high-vigor seeds have obvious growth advantages and production potential and are key to single-seed sowing. At present, the corn production in China gradually develops to the direction of mechanized single-grain precision sowing, so that the detection of the vitality of single-grain corn seeds is very necessary. At present, the method for identifying the vigor of the seeds mainly comprises the following steps of (1) visual inspection of the shape and color of maize embryo, wherein the embryo is protruded or shrunken, dark and matt, so that the seeds are fresh and have strong living force, and can be used as production seeds, (2) soaking and accelerating germination, firstly soaking 100 seeds in water for about two hours for swelling, placing the seeds on moist grass paper, covering the seeds with moist grass paper, placing the seeds in an environment with sufficient oxygen and room temperature of 10-20 ℃ for full germination (about 8 days), dividing the number of germinated seeds by 100 and multiplying 100 percent to obtain the germination rate, 3) red ink dyeing, adding 19 parts of tap water into 1 part of red ink to prepare a dye, randomly extracting 100 maize seeds, soaking the seeds in water for two hours for swelling, peeling the swelled embryo and milk embryo by forceps, uniformly placing the treated seeds in a incubator to submerge the seeds for 15-20 minutes, pouring the dye, and repeatedly flushing the embryo until the embryo is in red, and the embryo is a light color, and the germination rate is slightly increased by 100 percent. Aiming at the related technology, the inventor finds that the seed soaking germination accelerating method and the red ink dyeing method in the related technology have higher accuracy compared with an appearance visual inspection method, but can not ensure the integrity of corn seeds, and the accuracy and the efficiency of the three commonly used methods are all to be improved. Therefore, there is a need to provide a system for rapid and accurate detection of corn seed vigor without damaging the seed, reducing detection time consumption, and complexity of detection operation. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide a system for detecting the vigor of corn seeds, which can rapidly and accurately detect the vigor of the corn seeds, does not damage the seeds, reduces detection time consumption and detection operation complexity.
