我们的研究发现,磁场处理土壤引起一系列土壤机械物理性质的变化,如粘着力、粘结力、剪切力降低。磁场处理也引起土壤比表面ξ电位及表面电荷等电化学性质的变化。将这些理论问题应用于实际生产中去,我们研制了磁性犁,通过大量的试验证明:磁性犁可降低土壤耕作阻力,节省油耗,提高耕作质量,如能推广,可望得到巨大的经济效益和社会效益。 Our study found that the magnetic field treatment of soil caused a series of mechanical changes in the physical properties of soil, such as adhesion, adhesion, shear reduction. Magnetic field treatment also caused changes in the specific surface area of ​​the soil ζ potential and electrochemical properties such as surface charge. To apply these theoretical problems to actual production, we developed a magnetic plow. Through a large number of experiments, it has been proved that magnetic plow can reduce the soil farming resistance, save fuel consumption and improve the quality of cultivation. If it can be popularized, it will be expected to have huge economic benefits Social benefits.
