本试验在１９９１～１９９２年用磁化复合肥对新红星（Ｓｔａｒｋｒｉｍｓｏｎ）苹果树叶面喷施。结果表明：叶面喷施磁化复合肥可有效地提高新红星苹果树叶片和幼果的微量营养元素含量。与ＣＫ相比，喷施磁化复合肥后，叶片的Ｍｎ、Ｚｎ、Ｃｕ、Ｆｅ含量的平均提高率为５．１５％、１０．８０％、２１．５９％、２０．５１％；幼果的Ｍｎ、Ｚｎ、Ｃｕ、Ｆｅ含量的平均提高率为２７．１８％、５３．３２％、１９．７３％、３８．５３％。试验结果还表明：处理复合肥的非均匀稳恒磁场中心的磁感应强度Ｂ＝１５０ｍＴ效果最好，Ｂ＝１００ｍＴ效果次之，故在生产应用中磁感应强度Ｂ选取１００～１５０ｍＴ为宜。试验简便易行，有实用价值。
This experiment in 1991 ~ 1992 with magnetized compound fertilizer on the new star (Starkrimson) apple foliar spraying. The results showed that the foliar application of magnetized compound fertilizer could effectively increase the content of micronutrients in leaves and young fruits of apple tree. Compared with CK, the average rate of increase of Mn, Zn, Cu and Fe content after spraying magnetized compound fertilizer was 5.15%, 10.80%, 21.59% and 20.51% The average rates of Mn, Zn, Cu and Fe were 27.18%, 53.32%, 19.73% and 38.53% respectively. The results also show that the magnetic induction intensity B = 150mT at the center of non-uniform steady magnetic field is the best, and the effect of B = 100mT is the second. Therefore, the magnetic induction intensity B should be 100 ~ 150mT in production and application. Test is simple, practical value.
