中文摘要：

马铃薯在种植过程中的切块处理往往是病害的主要传播途径，因此获得有效的马铃薯种薯切块保护方法，对于防止病原菌通过切块的伤口感染薯块具有重要的意义。EM菌制剂是一种混合菌制剂，能够促进植物的新陈代谢，抵抗病原菌的侵染。试验采用不同处理的EM菌制剂结合活性炭对马铃薯种薯切块进行处理，对马铃薯种植后的农艺特性进行研究，结果表明，EM菌及活性炭处理后，马铃薯叶片中叶绿素含量，开花数及产量都得到了提高。EM菌制剂处理对产量影响由高到低的顺序为：灭菌EM菌处理＞EM菌离心液＞EM菌原液，不同处理EM菌制剂的稀释浓度对马铃薯产量的影响也存在差异，其中采用EM菌制剂灭菌液（稀释100倍）结合活性炭处理薯块，对种薯的保护性最好，产量提高了20.00%。

英文摘要：

The cut process of seed potato in production is the main route of the transmission of diseases,thusobtaining a reliable method for the protection of seed piece is of great significance in preventing the spread of diseasecaused by pathogens transmitted in wound infection of potatoes tubers.EM bacterial preparation is a stable mixedbacterium preparation that can effectively promote the metabolism of plants,and resist pathogens infection.Various EMbacterium preparations and activated carbon were applied to seed pieces of potato,and then agronomic characteristicsof potato plants after planting were analyzed.EM bacterial preparation and activated carbon increased chlorophyllcontent,flower number and tuber yield.The rank of tuber yield for various EM treatments was sterilized EM bacterialpreparation>centrifugalized EM bacterial preparation>origin EM bacterial preparation.Various diluted solutions of EMbacterial preparations of different treatments gave different tuber yields.EM bacterial sterilization solution(diluted100times)combined with activated carbon showed the best protection result for seed pieces,and the tuber yield wasincreased by20.00%.
