As the most basic and important production data for agricultural production, the degree of cleanliness has a very significant impact on production. In recent years, with the continuous deepening of production practices, the cleanliness value of most crops has increased by one percentage point, and this has led to a continuous increase in the demand for seed quality. The analysis of the degree of clarity in the detection of seeds is also getting more and more attention. For the analysis of seed's clarity, nowadays the seed wind clarity tester is generally used for analysis and determination.
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. It can be judged from this: (1) The damaged seed unit is larger than half of the original seed's own size. Although there is no embryo, it is still a net seed, and the other half is less than half of the original seed's own size. Although there are embryos, it should be classified as impurities; (2) Net seeds of grass seeds must have endosperm; (3) Structures not described in the net seed definition are classified as impurities, such as peanut husks are classified as impurities; (4) The separation is separated, such as rice, barley When it exceeds the length of the floret, it should be taken out as an impurity; (5) Damaged seed that has not apparently injured the seed coat or pericarp, regardless of whether it is empty or full, is used as a net seed or other plant seed; (6) The remaining seed must be quickly judged Whether the unit exceeds half of its original size, if it cannot make a quick decision, the seed unit is classified as a net seed or other plant seed.
After the sample is weighed and weighed, the sample can be separated by sieving, so as to objectively separate out the impurities and other plant seeds and reduce the analysis workload. The set of sieves used for screening seeds is generally composed of upper and lower two layers. The upper layer is a large-hole sieve, auxiliary hand-picking, separating net seeds and large crushing particles and impurities; the lower layer is a small-hole sieve, separating small particles, lean particles and dust Impurities. The sieve holes are divided into two kinds: round holes and long holes. The round hole sieves are separated according to the seed width and used for round or similar sieve seeds, such as rapeseed, corn, etc. The long hole sieve is separated according to the seed thickness. For long or similar to long seed seeds, such as wheat. The mesh size and shape should be determined according to the seed size and shape. When using, press the screen size from top to bottom, and the long-hole sieve screen holes should be parallel to each other, pour the sample into the upper screen, tightly cover, manual or electric screen, the long hole screen should follow the direction of the screen hole. Screening. Place on an electric screen or hand-operate for 2 minutes. After sieving, the layers in the sieve and the bottom box are poured onto the cleanliness analysis platform for analysis and identification. The net seeds, other plant seeds and impurities are separated, and then the various components are weighed separately and the unit is denoted by g. . Or directly use the seed wind purity meter to screen, so that you can reduce the operating steps, directly to obtain a more accurate sample.
By using the Seed Wind Cleanness Tester to analyze the clarity of crop seeds, it can be concluded that for the results of the determination, the weight percentages of the three components can be expressed, and the precision needs to be accurate to one decimal place. The sum of the percentages of the various components must be 100.0%. Ingredients less than 0.05% are reported in small quantities; if one component has a result of 0, they are reported as "-0.0-". When it is found that the weight percentage of a certain kind of impurity or a certain other plant seed reaches 1% or more, the type must be indicated on the result report form.
