Clarity Analysis How to Calculate and Express Correctly

How Clarity Analysis Calculates and Expresses Correctly

Seed clarity analysis is an important step in the inspection of seed quality, and the seed's clarity is directly related to the seed yield. Especially in the state of seeding, seeds with low clarity are prone to seedling deficiency and seedling breakage. Therefore, it is necessary to carry out a detailed analysis of the clarity of the seeds in the quality inspection of the seeds. In the early stage of the analysis of seed purity, we often used the seed wind analyzer, also called the seed blower. Seed hair dryers classify seeds according to their different floating speeds in the air. In addition, in the test of seed quality, the germination rate, purity, seed weight, and the like are often measured. In this case, an incubator such as a light incubator will be required. The function of the light incubator is the same as that of the seed germination box, which is to create a very suitable environment for the growth of the seed and artificially simulate the natural environment.

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. The results of the clarity analysis are calculated using more formulas, more complicated than the other three indicators, and the expression is cumbersome. The following sequence can be performed: (1) The weight of the three components of net seeds, other plant seeds, and impurities after calculation and analysis And (2) comparing the sum of the weights of the three components with the weight of the original sample, checking whether the increase in material during the analysis exceeds 5% of the weight of the original sample, which exceeds the weight of the original sample; (3) calculating the weight percentage of the three components. The calculation shall use the sum of the weights of the three constituents as the denominator, the full sample shall be calculated to one decimal place, the half sample shall be calculated to two decimal places, and the final result shall be one decimal place; (4) the final result of the three components shall be retained For fractional numbers, the sum is 100.0%, and less than 0.05% is expressed as “trace”, and is eliminated in the calculation. The result of zero is represented by “-0.0-”. If the sum of the three components is 99.9% or 100.1%, the net value is increased or decreased by 0.1% from the maximum value of the component. If the rounding value is greater than 0.1%, check for errors in the calculations; (5) The test results for the netity analysis include the weight percentages of the three components of net seeds, other plant seeds, and impurities. When determining the weight percentage of a certain kind of impurity or a certain other plant seed reaching or exceeding 1.0%, the type should be indicated in the result report.
