自1978年起,我国就开始研究磁化水和磁化粉煤灰对农作物的增产效果。多年试验表明,农田施用磁化粉煤灰,确有一定的增产效果。增产机理可能与磁化作用土壤电化学和土壤物理性质的改善有关,比如其中含铁矿物由于磁性的物理作用,改善了土壤团粒结构,促进土壤中物质转化和养分的有效化;由于物理化学的作用,减少了土壤对磷的固定,增加铵的解吸。另外,土壤磁化处理后,促进了作物体内生物酶的代谢活动,有利于增加产量。
Since 1978, China began to study the effects of magnetized water and magnetized fly ash on crop yield. Years of experiments show that the use of magnetized fly ash farm, do have a certain yield-increasing effect. The mechanism of yield increase may be related to the improvement of soil electrochemistry and soil physical properties caused by magnetization. For example, the iron-bearing minerals may improve the aggregate structure of soil due to the physical effect of magnetism, and promote the conversion of soil material and the nutrient utilization. As a result of physicochemical Role, reducing the soil of phosphorus fixation, increased ammonium desorption. In addition, after soil magnetization, the metabolic activity of the biological enzyme in the crop body is promoted, which is favorable for increasing the yield.
