不同类型叶面肥对晚熟油桃‘福美’果实品质的影响

Effects of Different Kinds of Foliar Fertilizers on Fruit Quality of Late Ripening Nectarine Cultivar Fumei

以晚熟油桃新品种‘福美’为试材,研究了喷施不同类型叶面肥(腐植酸肥、海藻肥、氨基酸钙肥)对叶片质量、光合性能和果实品质的影响。结果表明:喷施这三种类型的叶面肥均可显著提高‘福美’油桃叶片叶绿素含量和净光合速率,改善叶片质量,增加叶片光合能力;提高光合效率、PSⅡ最大光化学效率和光合性能;增加果实单果重,显著提高可溶性固形物、糖酸比,果实品质明显提高。综合效果以‘泰宝’腐植酸肥为最好。

A new late ripening nectarine cultivar Fumei was used as a test material to study the effects of spraying different kinds of foliar fertilizer（ humic acid fertilizer,seaweed fertilizer,calcium amino acid） on leaf quality,photosynthetic performance and fruit quality. The results showed that spraying the three kinds of foliar fertilizers significantly increased chlorophyll content and net photosynthetic rate,which could improve the leaf quality and photosynthetic capacity,the photosynthetic efficiency,maximum photochemical efficiency and photosynthetic performance of photosystem Ⅱ. Spraying foliar fertilizers also increased fruit weight,significantly increased soluble solids and sugar-acid ratio,so the fruit quality was improved obviously. The overall effects of Taibao humic acid fertilizer was the best.
