1. Accurately grasp the criteria for identifying net seeds, other plant seeds and impurities. Whether the results of the clarity analysis are correct or not, the key is to accurately grasp the criteria for identifying net seeds, other plant seeds and impurities. Since the difference between net seed and other plant seeds is obvious, the key to clarity analysis is to distinguish between net seeds and impurities, other plant seeds and impurities.

2, the correct choice of balance Because the clarity analysis needs to determine the weight of the components of the test sample, so the correct choice of balance is essential. Weighing with the balance includes weighing the submitted samples, the clarity analysis test samples, and the three components analyzed (net seeds, other plant seeds, and impurities).
3. Defining the weight of the sample The sample to be tested refers to the sample delivered to the laboratory. The clarity analysis test sample refers to the sample used for the test clarity item. The minimum weight of the two samples shall be in accordance with the standards of the Crop Seed Inspection Regulations. If the weight of the sample to be tested does not meet the specified weight, it should be replenished or re-applied.
4. Correct identification of heavy-duplex hybrids Heavy-duty hybrids are mixed with samples that are significantly different in size or weight and seriously affect the results, such as clods, small stones or small seeds. Large seeds and so on. Heavy-duty hybrids must have the following two conditions: one is that the volume or weight is significantly different from the seed being tested; the other is that the difference is a serious impact on the clarity analysis results.
5. Independently separate test samples The test samples used for clarity analysis should be separated from the test samples according to the specified method. The clarity analysis can be performed with one sample (full sample) of the specified weight, or two and a half samples (half the weight of the sample).
6. Reasonable selection of sieves After the samples are weighed, the samples can be separated by sieving to objectively separate impurities and other plant seeds, reducing the analytical workload.
7. Separately analyze, analyze, and identify the sieved sample on the seed clarity observation table. It can be used to analyze and classify the sample according to the identification criteria of net seeds, other plant seeds and impurities. Containers, because other plant seeds and impurities are generally lighter and smaller, do not lose these substances during operation, so as not to affect the analysis results. In addition, the lean seed of the bottom sieve is a complete seed unit and should be classified as a net seed or other plant seed.
The seed clarity observation table is also called the seed clarity table, which is used together with the amplifying device. The bottom of the observation table is equipped with a lighting device for observation and cleaning of seeds. The seed clarity observation table is designed and manufactured according to the principle of optical transmission, reflection and amplification. Used for cleaning seed and seed clarity detection and rice quality determination. The Top instrument is composed of a transmission light source system, a control table, a reflection light source and an amplifying device.
