摘要： 笔者研究不同叶面肥及其浓度对辣木营养品质的影响，旨在为辣木的田间栽培管理提供科学依据。对辣木分别喷施0.5%、1%磷酸二氢钾、0.5%自制叶面肥以及等量清水作为对照，探讨叶面肥对辣木各营养指标的影响。结果表明，喷施叶面肥对辣木品质有显著影响，喷施磷酸二氢钾可以显著提高辣木营养品质，0.5%磷酸二氢钾肥效最佳，可溶性糖、维生素C、蛋白质和黄酮含量分别对比照增加14.06%、55.73%、9.54%和8.25%，0.5%自制叶面肥处理的辣木维生素C与对照相比增加50.38%，其余指标均显著低于0.5%磷酸二氢钾。喷施0.5%磷酸二氢钾对改善辣木品质效果最佳，可运用于辣木田间栽培管理。

Abstract: The paper studied effects of different foliar fertilizers and their concentration on quality of Moringa oleifora, to provide certain bases for field management of M. oleifora. 0.5% KH2PO4, 1% KH2PO4, 0.5% self-made foliar fertilizer and equivalent water (control) were sprayed on M. oleifora, and the effects of foliar fertilizers on nutrition indexes of M. oleifora were analyzed. The results showed that spraying foliar fertilizers had significant effects on M. oleifora quality, and nutrition quality could be improved remarkably by spraying KH2PO4. Fertilizer efficiency of 0.5% KH2PO4 was the best, 14.06%, 55.73%, 9.54% and 8.25% higher than control in soluble sugar, vitamin C, protein and flavone. 0.5% self-made foliar fertilizer was 50.38 % higher than control in vitamin C, but significantly lower than 0.5% KH2PO4 in other nutrition indexes. As a conclusion, compared with other treatments, spraying 0.5% KH2PO4 has the greatest effects on quality of M. oleifora, which can be applied to field management of M. oleifora.
