为了提高杨梅果实采收和贮藏品质,以“荸荠”种杨梅为材料,在发育期施用不同水平的K、B肥组合,评价施肥对杨梅果实采收和贮藏品质以及贮藏期主要抗氧化酶活性的影响。结果表明:果实内的矿物质元素N、P、K、B含量以处理组合B2K1(6.0 g B/L+1.0 kg K/株)最高,Zn含量以处理组合B2K2(6.0 g B/L+1.0 kg K/株)最高。处理B2K1果实单果重量、可溶性固形物(TSS)含量、可溶性糖含量(WSS)及Vc含量最高,而可滴定酸含量最低。果实内矿质元素N、P、K、B、Zn含量与果实的单果重量、WSS、TSS、Vc等含量成正相关关系。在贮藏期,杨梅果实品质指标除TSS以外,其他品质指标含量都以处理B2K1下降最少;杨梅果实内POD、SOD、CAT酶活性均以处理B2K1最高;MDA含量以处理B2K2最低、处理B2K1次之。综合各种因素,以处理组合B2K1果实采收和贮藏期品质最佳,贮藏性能最优,处理组合B2K2次之。该结果可为高品质杨梅产业化生产施肥提供参考依据。
In order to improve the harvesting and storage quality of bayberry fruit, different combinations of K and B fertilizers were applied at the developmental stages to restore and recover the quality of bayberry fruit and the main antioxidant activities during storage Effect of enzyme activity. The results showed that the content of mineral elements N, P, K, B in the fruit was the highest in the treatment group B2K1 (6.0 g B / L + 1.0 kg K / plant) kg K / plant) the highest. The fruit weight, soluble solids content (TSS), soluble sugar content (WSS) and Vc content of B2K1 fruit were the highest while the titratable acid content was the lowest. The contents of mineral elements N, P, K, B, Zn in fruit were positively correlated with the fruit weight, WSS, TSS and Vc contents. In the storage period, except for TSS, the fruit quality index of Myrica rubra dropped to the lowest in B2K1; the activity of POD, SOD and CAT in bayberry fruit was highest in treatment B2K1; the content of MDA was the lowest in treatment B2K1 and the second was B2K1 . Combining various factors to deal with the combination of B2K1 fruit harvest and storage of the best quality, storage performance, the best combination of treatment B2K2. The results can provide a reference for high-quality production of bayberry industrial fertilizer.
