Pastoral Seed Inspection Specifications
Inspection Report
The revised standard is somewhat different from the international standard in terms of writing format. The international standard places all the appendices after the main text of all the inspection items, and most of the appendices in the specification are not used when they are used. However, this standard is different in that each item is a separate label with an abbreviation, the main content is compiled in the text, and the relevant The appendix is ​​attached after the main text of the standard. This standard is issued by the Ministry of Agriculture of the People's Republic of China and was drafted by the China Pasture and Grass Quality Inspection and Testing Center (Lanzhou), with participation of the Chinese Agricultural University.
The main drafters of this standard are: Li Ka, Yu Ling, Sun Tinghua, Zeng Hanjun. E9
GB/T2930.10—2001
IST A. The biggest risk in agriculture is that the seeds of the varieties used cannot show their production capacity. Seed inspection is used to assess the quality of seeds before planting to minimize this risk. Seeds are often a combination of different characteristics. These characteristics are extremely important to different sectors of the seed industry, such as producers, processors, storage, operators, farmers, certification bodies, and government agencies or departments responsible for their taxation. Under the guidance of the manufacturer, the final result of the test is the value of the seed. Seeds are living products. Their condition cannot be accurately predicted like that of inanimate or non-animal products. The test methods used must be based on scientific knowledge and the experience accumulated by seed inspectors. The accuracy and specificity required are determined by the current test. The standards and methods specified in this regulation must be applicable to the seed quality assessment of international research products. Therefore, the accuracy and specificity of the test methods must be achieved. When the trade of varieties crosses national borders, it is possible that they can be inspected by inspection offices in different countries. Therefore, it is very important that all inspections adopt consistent standard methods so that accurate inspection results can be obtained within the specified range. This regulation is divided into two parts: the main body of the regulation and the appendix. The main body of the regulation describes the purpose and principles of each item, the definitions adopted, and describes the methods and procedures used. The appendix introduces the definitions and expands the procedures and methods specified in the regulation. If the results of this procedure are completed on time and a complete medical particle inspection certificate is required, the procedure must be strictly followed. The screening of the provisions of the procedure should be consistent with the relevant details in the appendix to the regulations. It is recommended that countries should adopt this procedure and its contents as much as possible when managing domestic seed resources and implementing the national "Quality Management Law". Although this situation does not necessarily require the use of international seed inspection documents, it is recognized that when the results are consistent with this internationally accepted procedure and appendix text, the free implementation of the inspection will be carried out according to the requirements of the sender. For special issues encountered in seed evaluation, this inspection needs to take into account factors such as sowing season, soil type, commercial degree, etc. For seed monitoring, this The regulations and annexes only provide basic guidance. The relevant documents are supplementary. This regulation and annexes are formulated for the world's most common crops. Although not only the specific instructions, but also in principle also apply to other crops not covered by this regulation.
In addition, in order to provide adequate guidance, there are only equipment from specialized manufacturers: but this does not mean that the IST considers this equipment to be good, and does not exclude similar products from other manufacturers. 1 Standard

Regulation Seeds are sown randomly or in rows on a wide strip made of low-lying or other biodegradable materials. 4.6 Treated seeds are seeds that have only been treated with pesticides, dyes or other additives, but have not caused significant changes in their size, shape or weight. This type of seeds can be tested according to the standard for uncoated seeds. 5.1. Specific requirements of GB/2930.1-20. 5.2. Batch size: The number of seeds per day is 1×1030 seeds (10CCC units, 1CCC per unit), but the batch weight (including various coating materials) shall not exceed 12000kg (i.e. 400Ckg plus 500kg). When a single number is used to indicate the batch size, the total weight of the batch shall be reported on the inspection report: 5.3 The number of samples sent by the person delivering the sample should not be less than the number of pellets or seeds required by the table. The seed tape (spaced according to the method specified in G290.2001.3) should be taken out by the worker. If the packaged or finished seed tape (s) contains more than 20 seeds (20 units, each unit contains 1000 seeds), it can be combined into a basic unit (i.e., a container). If the sample used is less than , the following statement is made on the test result report: "The sample submitted for inspection contains only... seeds, which have not met the requirements of the test process."
The sample size (number of seeds) of pelleted seeds is formulated for the following items
Net substance analysis (also refers to the monitoring of plant species)
Weight determination
Pulp test
It also includes board seed determination
Other frequency soft seed dispersion determination (packaged seeds or seed number) size 2: Including nine seeds, coal seeds and seed weight samples, which do not comply with the sample size of less than 2F:000 Table 2 Seed items "sample size number of grains" To the specified project, of course, will be sent to the test room. 5.4 Samples sent according to the fiber collection and some prints. Samples sent for inspection shall not be less than 2 but the sample is less than 25 net pellets. 000
Test samples do not meet the requirements
Since the number of seeds in the coated seed sample is less than that of the same sample without coating, special attention should be paid to ensure that the sample is representative of the seed batch. During the pallet, handling and transportation, care should be taken to avoid changes in the sexual characteristics or sexual (sensitivity) of the seeds, and the samples should be packed in appropriate containers. 5.5 The number of test samples should not be less than the number of seeds or seeds specified in Table 1 and Table 2. If the sample is less, the number of seeds should be filled in the test report.
5.6 Obtaining test samples
Pelleted seeds can be sampled using the sample divider specified in GB/T2930.1--2001.2.2, but the separation must not exceed 2m: for seed belts (chains), some belts (chains) can be randomly taken out, and the number of seeds contained in them should be sufficient for inspection. 9 yuan
6 Pure original analysis
6.1
GA/T2930.10-2001
The pure original analysis of seeds in pelleted seeds and belts (blankets) is not required to be done. Generally, pelleted seeds are separated according to the provisions of 2: but seeds in the price (missing) do not need to be separated.
6.2 Definition of pelleted seeds
6.2.1 Clean pellets
Clean pellets include:
) Complete seeds with or without seeds; 1) Pellets with a surface area of ​​1% or more of the seed. Seeds of the species described in this article are obviously not free of this test, except for 6.2.35 that do not contain seeds. 6.2.2 Unpelleted seeds
Pellets should include:
1) Pelted seeds of any plant!
h) A magnetic pellet containing a seed of a plant species other than the one being tested; a pellet containing a single seed with chromatographic material on the surface of the seed and less than half of the surface area. 6.2.3 Impurities include:
a) detached chromatographic material;
h) chromatographic particles with obviously no chromatographic material;
c) any other material as residue according to the provisions of GB/T 2030.2-2031.3. 6.3 Principles of analysis
The test sample of pelleted seeds shall be divided into the following components: net weight, unchromatized seeds and impurities. Determine the percentage of each component. Try to identify all known impurities. If necessary, measure their weight percentage separately. 6.4 Other components
See GE/T 2930.—2011 Chapter 6:
6.5 Species Identification
To verify that the pellets contain the species specified by the test subject, remove one pellet from the clean pellet portion of the test, remove the pelletized material, and then determine the plant species of the pellet. For each test seed, remove one pellet from the pellet and identify the plant species.
6.6 Procedure
6. 6.1 The purity analysis of pelleted seeds shall be carried out by taking a sample from the sample submitted for inspection according to the provisions of 5.6. The size of the test sample is shown in Table 1. The purity analysis can be carried out by taking a full sample of the specified number of seeds or taking two samples from a single sheet (at least half of the number of test samples). The full test sample (or each half sample) shall be weighed in grams. The required number of decimal places (see Table 1 of GH2302-01) shall be achieved to meet the requirements of reaching decimal places when calculating various or partial percentages. 6.6.2 After the separation and weighing, the pelleted sample (or half sample) shall be divided into various 6.7 The calculation of the market value of each ingredient (see 6.3>) shall be completed. The net result of the analysis shall be the percentage of the total consideration. The total percentage of the ingredients shall be less than 5%. The product value of the product shall not be calculated by the type of product, except for the requirements of Chapter 8 of G12930.2-21. The calculation of the value of the market value shall be based on the total value of the various ingredients and shall not be based on the initial corrected volume of the test product. However, the total value of the various ingredients shall be compared with the heaviest volume. The analysis period shall be checked. 93
CB/I 2930.102001
If the quality of the sample increases or the error increases by 55% of the initial weight before analysis, it should be re-analyzed, and then the difference between the two samples should not exceed the allowable range specified in Table C of G3290.2-2JJ1. If the difference exceeds the allowable range, the relevant procedures in Chapter 6.5 of G3290.2-G1 should be used for the library test. In the identification of the species (Chapter 6.5), the number of samples found in each species should be filled in. The name and number of seeds. 7 Determination of the number of other plant seeds 7.1 This regulation only requires the determination of the number of seeds of other species. 7. Definition Other plant seeds refer to seeds of other species except pure seeds. The determination should be carried out in accordance with the definition of GB/T 293).22<1, 7.3 Rules The determination of the number of seeds of other plant species or the number of seeds of other species found in the test sample should be carried out in accordance with the definition of GB/T 293).22<1. Calculate the seed efficiency of the nuclear species (or population), and the result is expressed as the approximate number of kernels for the test nuclear number or the number of all other protected materials or specified seeds in the test seeds (> Chang'an (area)). See G20-201 Chapter 5 7.5 Procedure 7.5.1 Test products The test samples are divided into two halves according to the number specified in Table 1 and Table 2: 7.5.7 Tests should be made to remove chemical substances and should not be used in the same way. All other plant seeds must be removed from the entire sample or the specified species must be present.
7.6 Calculation of results
The determination shall be expressed as the actual number and the number of seeds found in the specified species or type of plant or type only, or as the number of seeds found in the specified species or type of plant ... When judging whether there is a significant difference between the two test results, the tolerance specified in Appendix A (Standard Appendix) of B/T2930.3--2001 shall be used. When comparing two products, the maximum growth or volume of the same product shall be determined according to 5/T23304-21H114.4 period, determine the percentage of seedlings in the column, the pellets used should be obtained from the clean pellets: seeds in the belt (with the materials of the materials in the book (medical) blow. When sending for inspection, or for the replacement of pellets or belts (speed) for the test results, the clean seeds can be checked by acid test from the pellets or belts (). Attention should be paid to the method that does not affect the germination ability of seeds. 82 The identification of the normal movement of the seedlings should be carried out according to the provisions of Appendix A of B: T2920! Standard time record. :-toilet pellets, if at least one of the species described by the sender is understood Normal young seeds, that is, only half of the seeds are not delivered. If it is not a light seed, even if it grows up, it cannot be included in the scope of production, but its value should be reported. 8-3 The original seed pellets must be cleaned and pulled out of the test vehicle. The pellets must be kept in the state of receiving. The seeds must be washed or soaked. The seed belt (tunnel) must be washed with water to remove the seeds. 34
