摘　　要：研究了磁场处理番茄种子及育苗用营养土对种子活力、苗期长势的影响．结果表明，湿种子经磁场处理后，种子活力明显提高．根据种子活力及苗期长势初步确定番茄种子最佳处理磁场的磁感应强度为２００ ｍ Ｔ和３００ ｍＴ，处理时间１０ ｍｉｎ．The effects of treated seed of tomato and soil with magnetic field on seed viability and seedling growth were studied in this paper.The results showed that,seed viability was improved by magnetic field treatment.According to comprehensive analysis of seed viability and seedling growth,200 mT and 300 mT for 10 minutes were the optimum magnetic field intensity on tomato seed.The soil for breeding seedling by magnetic field was made the seedling of tomato stout.
