摘要
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。
The foliage of starkrimson aPPle trees were sprayed with the magnetized compound fertilizer during 1991-1992. The results indicate that the magnetized compound fertilizer can remarkably increase the micronutrient content of the foliage and young fruit to starkrimson aPPle trees. Average increasing rate of Mn、 Zn、 Cu、 Fe、 content of the foliage are 5.15 %, 10. 80%, 21. 59%, 20. 51% respectively. Average increasing rate of Mn、 Zn、 Cu、 Fe content of the young fruit are 27.18%. 53. 32%、19. 73%、 38. 53% respectively. The results also indicate the effect of the treatment for the compound fertilizer is best when the magnetic induction (B) of the un-uniform steady magnetic field ranges between 100-150mT.The method is simple and practicable.
