Through the hygienic inspection of seed samples, the hygienic status of seed batches can be inferred, so as to compare the use value of different seed batches, and at the same time, measures can be taken to make up for the deficiency of germination inspection.
According to the inspector's requirements, determine whether there are pathogens and pests in the sample, and try to choose the appropriate method to estimate the number of infected seeds. For seed batches that have been treated, testers should be required to explain the treatment methods and chemicals used.
