Seed samples are important basic materials for seed research. They are representative, effective and complete. These are also important conditions that affect the test results. Therefore, we must attach importance to all aspects of the sample receiving, distribution, circulation, preservation, disposal, and identification of seed samples in the work of the seed sample, and implement effective quality control. The application of seed standard sample library management software in the seed sample database is very effective, and it is also an important equipment for modern seed banks.
Firstly, the seed samples were checked to check whether the seed samples were packaged and sealed, whether the weight was in accordance with the minimum weight of the test samples of different test items specified in the seed inspection procedures of GB/T3543.2-1995. And determine the nature of its inspection, such as commissioning the inspection mark "C", filling the age and sample number. The identification card is affixed to the seed sample bag, and the content includes the serial number, the name, the date of storage, and the inspection status, which are easy to identify and save. Seed samples should be stored according to the type of inspection and different types of crops in order to facilitate the search. The sample library shall be safe, non-corrosive, non-corrosive, clean and dry, and low temperature (maximum temperature does not exceed 15-18 °C). The number of doors and windows in the sample room shall be reduced to a minimum, and shall be covered with a gauze to prevent insects from entering. Set up special management, regular monitoring of the temperature and relative humidity in the sample library, make records, find anomalies and timely solutions, minimize the quality deterioration of seed samples, maintain the original germination rate, and eliminate insect damage to the seed samples.
The application of the seed standard sample library management software, when submitting the sample for inspection to the inspection agency, the sample manager shall carefully check the status of the sample, and record the information such as crop type, species name, sample weight, and sample delivery time. When receiving the entrusted inspection samples, the entrusting party is required to fill in the entrustment orders. In addition to recording the crop species, the name of the varieties, and the inspection items, the sample weight, date of delivery, date of report, etc. should also be recorded, and the entrusting party should be required to sign the sample. The inspection task of the seed sample is issued by the business office. The inspector holds the inspection notice and collects the inspection sample and signs the sample distribution form. At the end of the inspection at the end of the inspection, the sample administrator will weigh and register the inventory. The storage time of samples varies according to the test item. In general, the sample storage time should last at least until after the objection period of the inspection result. The sample for the purity test of the variety should at least preserve the next planting season of the crop. After the preservation period expires, the sample manager fills in the seed sample destruction processing form after the approval of the person in charge of the inspection agency. The content includes information such as the type, name, reason, quantity, time, approver, and destroyer of the destroyed crop.
