Scientific farming is inseparable from the inspection of seed quality, which is also an important means for determining the seed rank and value of use of seed breeding. In the quality inspection of crop seeds, 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 using a seed intelligent counting system to sample and conduct tests on paper (TP) and inter-paper (BP), it is difficult to count the number of seedlings that are emitted in one-to-one correspondence. When germination tests are performed in sand (S), the seed ball is used. Buried in the sand, the roots of the young plants are intertwined, and in the case of a long head, once the seedlings leave the bulb, it is easy to cause confusion in counting.
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 seed smart counting system was used during the experiment sampling.
Through the counting and sampling research of the seed intelligent counting system, the seeds can be separated, and the seedling germination consequence cover and the seedling 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 sprouted seedlings, and the correct counting result can be obtained. , improve the accuracy of the germination test. Not only can the test method be harmonized, but it will also greatly increase the accuracy of the germination test.
