摘要
用5年生巨峰葡萄,于1986—1988年连续3年试验,结果表明:结果枝数、果穗数与单株产量关系密切,而与主干截面积则无关.株产量如超过10kg时,可溶性固形物急剧下降,含酸量上升.如以1.5m×3m株行距,从产量、品质及负载量角度考虑,每hm^2应控制在2250kg左右.
Three years successive experiment with 5-year-old Kyoho grapes (Vilis labruscana Bailey) in 3 grape vinegards indicated that numbers of shoots and clusters closely related with yield per tree but not to cross-sectional areas(CSA) of main vines. Soluble solids would decreased rapidly and titratable acidity increased if the yield per tree exceeded 10kg. With planting distance of 3m × 5m, considering the relationship between quality and yield. The yield per hm2 sould be controlled in about 2250kg.
