摘　　要：在综合前人研究的基础上 ,结合自己的研究成果 ,系统地阐述了磁处理 (如磁场、磁化水、磁改良剂等 )对土壤微生物、酶活性以及种子萌发和植物生长的影响 。In this paper, effect of magnetic treatments on microorganisms, enzymes,seed germination and plant growth was expounded systematically. In 0 15T(Tesla) and 0 35T magnetic fields, soil breathing intensity and activity of invertase were improved, but bacteria growth was inhibited. After applying magneto meliorational reagents to soil, the rate of seed germination was increased, growth of the seedling was sped up, and activity of polyphenol oxidase was decreased. Micro mechanisms of bilolgical effects of magnetic fields were also discussed in this paper.
