Seed quality inspection is an important method for scientific farming in the year. In the inspection of crop seed quality, the germination test is one of the important indicators. As the sugar beet is a complex embryo seed, the seed ball is composed of pericarp and seeds. The pericarp is divided into husk and fruit cover. The texture is hard and the outside is surrounded by wooden calyx. The size of the bulb is irregular, including 3 to 5 seeds. After the emergence of 1 to 5 seedlings, seedlings drilled after the fruit shell, the fruit off, the seedlings followed by the ball. When conducting tests on paper (TP) and inter-paper (BP), it is difficult to count the numbers of seedlings that are emitted in one-to-one correspondence. When germination tests are performed in sand (S), the seed bulbs are buried in sand, and the roots of young plants are Intertwined with each other, in the case of a long, once the seedlings leave the bulb, it is easy to cause confusion in counting. Seed smart counting system has a very important role in the counting of seed samples.
According to the germination test standard for crop seed inspection regulations, it is stipulated that the complex seed unit is counted as a single seed and the test result is expressed as a percentage of the seed unit that produces at least one normal seedling. This shows that in a sugar beet bulb, as long as a normal seedling grows, a normal seedling seed unit is produced. In view of the characteristics of sugar beet seed germination experiment, after many experiments, we believe that the use of guillotine paper bed as germination test of sugar beet seed germination test has good counting effect. The specific method is as follows: The paper is cut into strips with a width of 13cm, and pleated with a ten-fold pleat pattern is laid on the bottom of the germination box of 18cm×13cm×9cm. The size of the beet bulbs is laid in each pleat groove. Into 5 to 10 bulbs, use 4 to 8 germination boxes, a total of 400 seeds.
The counting application of the seed intelligent counting system found that this germination bed can separate the seeds, the seedling germination consequence cover and the seedlings are in good correspondence and easy to observe, and at the same time, the twining of the roots of the young plants can also be reduced to facilitate the counting of the germinating seedlings, and the correctness can be obtained. The counting results improve the accuracy of the germination test. Therefore, we recommend adding the crepe paper method to the germination bed test in the germination test of the sugar beet seed in the germination test of the crop seed test protocol, which not only can unify the test method, but also greatly improve the accuracy of the germination test.
