不同浓度Hoagland营养液对‘藤稔’葡萄树体生长和果实品质的影响

Effect of different Hoagland solution concentrations on vine growth and fruit development of‘Fujiminori’grapevine

实验以8年生‘藤稔’葡萄为实验材料,研究了用5组含氮量分别为240-80-240、180-60-180、120-40-120、60-30-60和30-10-30 mg/L的霍格兰氏(Hoagland’s)营养液供给肥水对不同生育期(萌芽期-转色期、转色期-成熟期、成熟期-萌芽期)‘藤稔’葡萄树体生长和果实品质的影响。结果表明,处理1(N:240-80-240 mg/L)的叶绿素含量最高,新梢长度最长,但果实品质较差;处理3(N:120-40-120 mg/L)的可溶性固形物含量最高(18.17%),果皮花色苷含量积累较多,果实糖酸比最高,果实品质最优。上述结果为‘藤稔’葡萄的设施栽培水肥一体化管理提供了实验依据。

Experiments were conducted with 8-year-old‘Fujiminori’grape vines to investigate the effect of the concentration of Hoagland(calculated by nitrogen standard,the nitrogen contents were 240-80-240,180-60-180,120-40-120,60-30-60 and 30-10-30 mg/L,respectively)at different growth and development periods(germination-véraison,véraison-maturity,maturity-germination)on vine growth and berry quality.The research found that both the shoot length and leaf chlorophyll content under treatment 1(N:240-80-240 mg/L)exhibited the highest level,but the content of soluble solids was not as high as treatment 3(N:120-40-120 mg/L).Treatment 3 had the highest content of soluble solids(up to 18.17%),accumulated greater anthocyanin,and the berry’s sugar-acid ratio was the highest,which resulted in better berry quality than other treatments.The above results can be used as a reference for water and fertilizer integration management of‘Fujiminori’grape cultivation.
