We know that in the process of using the seed clarity table to analyze the seed's clarity, the seeds need to be divided into three parts: net seed, other plant seeds, and impurities. The net seed and other plant seeds have obvious characteristics. In the case of differentiation, it is relatively easy, but if the impurities are relatively summarized, the impurities can be accurately selected and strict criteria for discrimination are required. The following substances can be regarded as impurities.
1. Removed sterile florets, empty glumes, inner and outer pods, pods, stems and leaves, straw, cones, scales, fruit wings, bark fragments, flowers, nematode worms, fungal bodies (eg, ergot, sclerotia Spore clusters of smut, smut, sand, gravel, and all other non-seed materials (eg, pests, insect feces).
2. Seed units that are clearly free of true seeds.
3. Seeds of leguminous family and cruciferous family with completely peeled seed coat.
4. Fragments of broken or damaged seed units are one-half or less than half their original size (eg, discolored, rotted, flattened, crushed seeds).
5. Brittle and fragile, pale, milky white dodder seeds.
In the analysis of seed cleanliness, an important part of the content is the differentiation of impurities, and the application of seed clarity workbench is to facilitate the workforce to better distinguish them, thereby increasing the seed's clarity, and the seed's net Most of the samples after the degree analysis are used to determine the vitality, germination rate, purity, weight, etc. of the seeds. Therefore, the result of the analysis of the seed's clarity will affect the accuracy of subsequent measurement items. Therefore, it is necessary to provide quality and safety for agricultural production. Seeds, you need to use the seed cleanness table, do a good job in the analysis of seed cleanliness.
