Seed health refers to the seed health status. It refers to whether seeds carry harmful organisms such as fungi, bacteria, viruses, or pests, and whether they are affected by pathogens, pests, and adverse environmental factors such as element deficiency, causing biological or physiological diseases or damage. This includes morphological injuries caused by physical, chemical or animal forces as well as physiological damage caused by climatic factors such as cold damage. Broadly speaking, seed health inspection has the dual task of quarantine and inspection of seed value identification. The trade of seeds is the best way for pests to travel long distances, and the pests carried by seeds are subtle and difficult to detect. At present, the international inspection of seed health has completely departed from traditional morphological and biological methods. It combines state-of-the-art equipment and cutting-edge biotechnology to effectively control the pests that may be carried by seeds. However, the inspection technology of seed health in China is backward, especially in the Hexi Corridor, the largest seed production base in the west. The construction and inspection of seed health laboratory is still at a blank. For this reason, it is imperative to establish a seed health laboratory in the western universities.

To this end, the establishment of a seed health laboratory in the Hexi Corridor, which has the largest breeding area in the western region, can not only detect indoor pathogens but also detect pathogens in production areas, so that the two can be combined organically and the accuracy of seed health testing can be improved. Improve and provide more fair inspection reports to seed companies, seed administrative departments and judicial departments. At the same time, it can improve the quality of seed marketing and increase the economic benefits of seed.

Seed pathogen detection From the basic work of sampling, weighing, moisture and purity determination, equipped with equipment and applications are: photoelectric analysis balance, electronic analytical balance, electronic precision balance, equal analysis days, mainly to complete the seed weighing work; electronic automatic Counting instrument, counting instrument, number plate, etc., mainly for the determination of 1000-grain seed weight; computer moisture analyzer, electric thermostatic blast drying oven, crusher, etc., mainly to complete the determination of moisture; electric filter, wind classification instrument, Grain screening, pest screening, etc., mainly to complete the clarity analysis; Ding sampler, horizontal format sampler and other sampling tools. The purpose is to use routine methods to analyze the correlation between seed pathogens and seed clarity and moisture, as well as the hazards and effects of seed pathogens on seeds.
