配方施肥对美人指葡萄生长和果实品质的影响

[目的]研究配方施肥对美人指葡萄生长和果实品质的影响。[方法]以四川省彭山区避雨栽培条件下6年生美人指葡萄为试材,分析了配方施肥对美人指葡萄生长与果实品质影响。[结果]基肥株施3.6 kg干鸡粪、1.0 kg过磷酸钙与0.09 kg硫酸镁,萌芽肥株施0.18 kg尿素与0.01 kg速效硼,壮果肥株施0.25 kg磷酸一铵与0.09 kg尿素,着色肥株施0.40 kg硫酸钾的配方施肥能使美人指葡萄生长健壮,显著提高枝梢长度、粗度及叶片面积,增加果实的纵横径、粒重、单穗重,还能提高美人指葡萄浆果的可溶性固形物、总糖、VC的含量,降低可滴定酸的含量。[结论]合理施肥能显著促进美人指葡萄的生长及提高内在品质。

Effects of Formula Fertilization on Growth and Fruit Quality of Manicure Finger Grape

Objective]Effects of formulat fertilization on growth and fruit quality of Manicure finger grape were investigated.[Method]6-year-old Manicure Finger grapevine were conducted under rain-shelter in Pengshan County of Sichuan Province to investigate growth and fruit quality by formula fertilization.[Result]The results showed that formula fertilization by using dried chicken manure 3.6 kg /plant , calcium super-phosphate 1.0 kg/plant and magnesium sulfate 0.09 kg/plant as based fertilizer, using urea 0.18 kg/plant and available boron 0.01 kg/plant as sprouting fertilizer, using ammonium dihydrogen phosphate 0.25 kg/plant and urea 0.09 kg/plant as fruit enlargement fertilizer, using po-tassium sulfate 0.40 kg/plant as veraison fertilizer, could promote the Manicure Finger grape growth and improve the length and diameter of shoot and leaf area, increased the size, grain weight, and single panicle weight, meanwhile, enhanced the content of soluble solids and total sugar and VC and reduced the content of titratable acid.[Conclusion]Rational fertilization could improve significantly the growth and fruit qual-ity of Manicure Finger grape.
