对大多数作物而言,各种病害的防治十分重要,特别是对于高品质种子的繁殖。植物病原菌大大降低作物种子的品质和产量。成批的种子往往成为种传病原菌栖息的温床,而种子成为病原体有效传播的工具。虽然种子处理不能代替健康种子,但当种子活力低,种皮破损时,或种植时土壤、气候条件不利,出苗迟,如种植早土壤温度低、土壤干燥、苗床差,种子处理能有效提高出苗率。种子处理是消灭或减少种传病原菌的重要方法,特别在种子繁育中或对 For most crops, the control of various diseases is very important, especially for the breeding of high-quality seeds. Phytopathogenic bacteria greatly reduce crop seed quality and yield. Bulk seed tends to be a breeding ground for pathogenic bacteria, and the seed becomes a tool for the effective transmission of pathogens. Although seed treatment can not replace healthy seed, seed treatment can effectively increase emergence when seed vigor is low, seed coat is damaged, soil or climatic conditions are unfavorable during planting, and emergence is delayed. For example, early planting soil temperature is low, soil is dry and seedbed is poor, rate. Seed treatment is an important way to eliminate or reduce pathogenic bacteria, especially in seed breeding or
