磁场处理对花椰菜种子萌发和生长的影响

Effect of Magnetic Field Treatment on Cauliflower Seed Germination And Seedling Growth

以3500GS8h、3500GS12h、3000GS8h三种静止磁场处理为手段,研究了不同强度和时间静止磁场对花椰菜种子萌发及生长的影响.结果表明,磁场处理种子后,种子的发芽率提高幅度为2%—25%;发芽势提高幅度为8%—29%;株高、茎粗、展幅、最大叶长和最大叶宽等均比对照提高,花椰菜的平均产量提高了12.5%—42.5%.同时,获得了不同磁场处理后花椰菜植株生长速度的数学模型.

The paper studied on the impact on germination and growing of the cauliflower seeds treated by the static magnetic field under three different intensity and time, 3500GS8h, 3500GS12h, 3000GS8h. The results showed that the rate of seeds germination improves 2% -25%, potentiality improves 8% -29%.The height, stem diameter, exhibition sites, maximum leaf length and maximum leaf width is improved than those in the control groups. And the average production of cauliflower improves 12.5% -42.5%. Furthermore, mathematical model of growth rate of cauliflower treated by different intensity of magnetic field was obtained.
