磁的现象是人们早巳熟知的,但是如果告诉你,磁用在农业上可以增加产量,你可能会感到惊异了。其实,这没有什么可奇怪的。近几年来,大量的研究结果表明,磁场对于生物,就如同空气、水和阳光一样,是一切生命不可缺少的,科学实验还表明,磁场对于生物大分子、细 Magnetism is well known to all, but you may be surprised if you tell us that magnetism can increase yields in agriculture. In fact, this is nothing strange. In recent years, a large number of studies have shown that magnetic fields are indispensable to all living things, just like air, water and sunshine. Scientific experiments have also shown that the magnetic field for biological macromolecules, fine
