Three-Yuan energy and electromagnetic field are applied to gather the antibody produced by inoculating cabbage against TuMV artificially upon seeds. By inoculating and selecting the next generation of these seeds, 1. 67%-5. 58% and 4. 3%- 4. 44% healthy plants are got respectively, showing an unprecedented result and great potentiality of Three-Yuan energy as well as a new practical prospect of magnetic field.
