Abstract: The study aimed to discuss the effect of magnetic field on the biological effect of maize seeds. With the ZS-CⅢ composite magnetic processor compound produced by alternating current magnetic field, magnetic field intensities of 250 mT (A) and (B) 300 mT were used to deal with maize seeds respectively; and taking Zhengdan958’and‘Zhengdan2201’and 5 hybrids: 12HY617×12HY741, 12HY647×12HY741, 12HY751×12HY601, 12HY576 × 12HY436, 12HY731 × 12HY592 as test materials, the author studied the effects of different magnetic treatment doses on the germination indexes of the maize seeds. The results showed that maize seeds germination energy and germination rate were improved by the composite magnetic field treatment, the highest increase were 26.7% and 30.4%, respectively; the content of chlorophyll increased by 8.17%-28%; the weight of roots, stems and leaves and the length of roots at seedling stage were higher than that of CK. But the length of stems at seedling stage did not increase significantly. All the indexes did not show significant difference between A and B of magnetic treatments. So the magnetic field treatment could significantly improve the germination rate, germination potential of maize seeds and the content of chlorophyll in leaves, increase the length of roots, dry weight and fresh weight of stems and leaves at seedling stage. The study laid a good foundation for increasing the maize yield.
