    摘要:

    通过田间小区试验,研究了有机无机专用复合肥对葡萄产量、品质、养分吸收及累积量的影响。结果表明:施用推荐量专用肥,葡萄产量比不施肥和习惯施肥分别增加了25.8%和5.1%;葡萄果实可滴定酸比不施肥、习惯施肥和等量专用肥显著降低,减幅为10.7%~42.9%;施用推荐量专用肥提高了葡萄果实可溶性固形物1.8%~8.2%、Vc 6.4%~77.7%以及固酸比10.2%~60.4%;施用专用肥显著提高葡萄叶片Fe、Cu及果实Fe含量;而施用推荐量专用肥比习惯施肥、等量专用肥处理减少氮磷钾施用总量42.5%。因此,施用推荐量有机无机专用复合肥,既保证葡萄产量、改善果实品质,又减少氮磷钾施用总量,节约成本。

    Abstract:

    Field experiment was conducted to study the effects of organicinorganic special compound fertilizer (OISCF) on fruit yield,quality,and nutrient uptake of grape.Four treatments were set: CK (no fertilizer),XG (traditional fertilization),DL (equal total of N,P2O5,K2O amount of OISCF was used instead of normal fertilizers) and TJ (recommend amount of OISCF).The results showed that the grape yield of TJ was increased by 25.8% and 5.1% comparing with CK and XG respectively.Compared to CK,XG and DL treatments,the TJ grape fruits titratable acid decreased significantly by 10.7%~42.9%,total soluble solid increased by 1.8%~8.2%,Vitamin C increased by 6.4%~77.7%,and TA/TSS increased by 10.2%~60.4%.However,the total amount of N,P2O5 and K2O fertilization of TJ treatment was 42.5% less than the treatments of XG and DL,while grape leaf Fe,Cu contents and fruit Fe absorption were increased significantly by organicinorganic special compound fertilizer.In conclusion,recommended fertilization of OISCF kept grape fruit yield and improved fruit quality but declined the N,P2O5 and K2O application rate considerably.
