摘要
两年试验结果表明，水稻施用多元磁肥有效穗明显增加，６６７ｍ２产量较施用未磁化肥和复合肥的增产２８．７～４７．６ｋｇ，增产５．２％～１０．３％，差异达显著或极显著水平；净增值５４．３０～９９．１５元。同时可提高单位养分产量１．７１～２．４１ｋｇ。
The magnetized polybasic fertilizer (MPF) is a new type of compound fertilizer made under certain magnetic field intensity with flash as magnetic media and nutrients of NPK as main body. The experimental results for two years as follows: MPF obtained an increase product of 28.7～47.6kg/mu (an increase rate of 5.2%～10.3%) at 5% or 1% significant difference for rice than that of unmagnetized fertilizer and compound applied, and an additional net value of 54.30～47.6 yuan/mu gained. Meanwhile an additional product of 1.71～2.41kg per unit nutrient could be achieved.
