磁化水灌溉促进作物增产机理的MD模拟研究

为分析磁化水灌溉促进作物增产的机理，采用分子动力学模拟(Molecular dynamics simulation，简称MD)方法对其作用机理进行了模拟研究，模拟结果表明，在优化磁场作用下，水的表面张力系数和粘滞系数降低、扩散系数增大，使水的渗透性和扩散能力增强；同时水体系中自由的单体水分子和二聚体水分子增加，使之更容易进入作物细胞内，从而促进细胞的新陈代谢，增强细胞活力，利于植株的光合作用和对营养物质的吸收，促进作物生长发育。磁化水灌溉实验在广饶县农业科技示范园进行。实验结果表明：在优化磁场(B=0．2T)作用下，磁化水灌溉使西红柿R-144小区增产9．8％，西红柿金珠小区增产11．3％。

Molecular Dynamics Simulation of Mechanism of Increasing Vegetable Yield by Irrigated Magnetization Water

Molecular dynamics simulations were adopted to investigate the mechanism of increasing vegetable yield by irrigated magnetization water. When magnetic field strength is 0. 2T, decreasing the surface tension and viscosity of water and increasing the diffusion coefficient of water made the osmosis and fluidity of water enhance. Treated by magnetic fields, the monomer and dimer water molecules increase, and are easy to enter the vegetable cells, accelerate the metabolism of vegetable cell, and are propitious to the photosynthesis of vegetable and the absorption for nutriment, and accelerate the growth of vegetable. The results the irrigation experiment in Guang rao country show that the yield of R-144 tomato field increases 9. 8%, and the yield of Jinzhu tomato field increases 11. 3% by irrigated magnetization water.
