    摘要:

    为探究土壤硼锌钼水平对蓝莓果实品质的影响,选取微量元素长期定位试验中常规施肥(CK)、硼肥(B)、锌肥(Zn)和钼肥(Mo)4个处理,分析不同施肥处理蓝莓果实品质指标及矿质元素含量的变化。结果显示:施用硼、锌、钼肥处理后蓝莓果实可滴定酸含量下降,果实固酸比相较对照(CK)分别增加了26.28%、14.73%、27.56%;施用硼、锌、钼肥处理蓝莓果实中氮磷钾含量及其累积量显著增加,推测施用硼锌钼肥有利于植株氮磷钾养分向果实转移;施锌和施硼处理后蓝莓果实锌累积量较对照分别提高28.95%和21.88%;硼、锌、钼处理蓝莓果实钼累积量较对照分别增加了49.37%、58.86%、245.57%;主成分及综合评价分析结果显示,各处理间蓝莓果实品质的综合得分为Mo>Zn>B>CK。结果表明,施用微量元素硼、锌、钼后果实综合品质得到提升,其中施钼对蓝莓果实品质提升效果最佳。

    Abstract:

    To explore the differential effects of boron (B),zinc (Zn),and molybdenum (Mo) on fruit quality and mineral nutrients content of the blueberry,four treatments including conventional fertilizer (CK),B,Zn and Mo fertilizer were conducted in a long-term position experiment of trace elements. The results suggested that the application of B,Zn and Mo could significantly reduce the titratable acid content of blueberry fruits,resulted in the increases of solid acid ratio of fruit by 26.28%,14.73%,and 27.56% compared with the control,respectively. The application of B,Zn and Mo significantly increased the content and accumulation of nitrogen(N),phosphorus(P),and potassium(K) in blueberry fruits,indicated that the B,Zn,and Mo were beneficial to the transfer of N,P,and K elements from plants to fruits. In addition,Zn and B treatments increased Zn accumulation by 28.95% and 21.88%,respectively. Besides,B,Zn,and Mo treatments increased Mo accumulation by 49.37%,58.86%,and 245.57%,respectively. Generally,the comprehensive score of blueberry fruit quality among all treatments was Mo>Zn>B>CK by principal component analysis,indicated that application of B,Zn,and Mo could improve the comprehensive quality of blueberry fruit,especially the Mo application.
