摘要
目的 :探讨磁生物效应对药用植物生长和发育的影响。方法 :采用带有传送装置的梯度磁场对山药珠芽进行播前处理 ,并对珠芽的苗期生长进行评价。结果 :经磁场处理两遍的 ,苗期生长最好 ,与对照相比 ,出苗率提高 38.6 0 % ;平均根长增加 2 .6 2cm ,单株发根数提高 8%。经统计学F测验 ,平均根长F =19.98,F0 .0 5=6 .94,F0 .0 1=18.0 0。结论 :适宜的磁场强度可促进药用植物生长。
Objective:To probe into the bioeffect of gradient magnetic field on the growth and development of medicinal plants.Methods:Gradient magnetic field with transmission belt was applied to treat the stem pearis of Dioscorea opposita before sowing and an evaluation of the pearl growth during the seedling stage was made. Result: Treated with twice gradient magnetic field,the stem pearls grew the best in the seedling stage.Compared with the control,the rate of emergence increased by 38.60%,root number increased by 8%,and the average root length increased by 2.62 cm.By F Test,the average root length was F =19.98, F 0.05 =6.94 and F 0.01 =18.00.Conclusion:Proper magnetic field intensities can promote the growth of medicinal plants.
