The clarity of seeds occupies a very important place in the evaluation of seed quality, so the analysis of the clarity of the seed quality is very important. So what is a degree of clarity? This mainly refers to determining the weight percentage of different components of the test sample and the characteristics of the sample mixture, and deducing the composition of the seed lot accordingly. The purpose of this analysis is to analyze the net seed and other plant seeds and impurity components in the seed sample. The analysis of seed clarity can be performed using a multi-functional seed cleanness table for observation and analysis.
After recognizing the important role of seed cleanliness, China's relevant regulations have increased the cleanliness value of most crops by one percentage point. Because of the increase in the value of the cleanliness values ​​in the quality standards, the requirements for seed quality have also been correspondingly raised. And the inspection agency should pay enough attention to the clarity analysis in the subsequent seed testing. Clarity analysis is more complex in the operation and calculation of the four major seed quality inspection items (clarity, purity, germination rate, and moisture). Now it is combined with years of practice and theoretical experience in the analysis and training of cleanliness. Problems that are prone to occur, and put forward the technical requirements for the successful completion of this test for the reference of the seed inspection personnel.
The key to the correctness of the Clarity Analysis lies in the ability to accurately determine the criteria for identifying net seeds, other plant seeds, and impurities. The main principles for the identification of net seeds are stipulated in the General Principles of Distinction, but for different genera or species, specific problems should be specifically analyzed. Therefore, the definition of net seed definitions has been formulated for each genera or species. Since the net seeds are significantly different from other plant seeds, the key to the clarity analysis is to distinguish net seeds from impurities, other plant seeds and impurities. In order to better grasp the criteria for distinguishing between net seed, other plant seeds, and impurities, it is necessary to fully understand the meaning of the two main principles of net seed and the detailed definition of net seeds.
General seed samples need to be analyzed through a certain process. Screening is a preliminary step in the analysis. The screened samples are laid on a multi-functional seed cleanness table (or in a clean analysis tray). The sample can be analyzed and classified according to the identification criteria of net seed, other plant seeds, and impurities with a certain instrument and then loaded into the corresponding container. Since the seeds and contaminants of other plants are generally lighter and smaller, do not lose these substances during operation to avoid influence. Analyze the results. In addition, the skinny seed of the bottom sieve is a complete seed unit and should be culled as a net seed or other plant seed.
After the seed sample was analyzed using the multi-functional seed cleanness table, the results obtained included the weight percentages of the three components of net seeds, other plant seeds, and impurities. If the weight percentage of certain impurities or other plant seeds measured reaches or exceeds 1.0%, the type should be noted in the results report. In this way, scientific test data can be provided for the accuracy of the seed's clarity.
