山葡萄不同株行距和架式对果实品质和产量的影响

Effects of different vine space and row space and trellis on fruit quality and yield of Vitis Amurensis Rupr.

为提高山葡萄主栽品种双红、双优和左优红果实品质和产量,以双红、双优和左优红为试材,进行不同株行距和架式试验的结果表明:采用篱架和棚架建园株行距0.75m×2.5～3.0 m的树,进入始花期和丰产期早,坐果率高、落果率低、果实酸低糖高、产量高。双红、双优和左优红适宜的株行距和架式是0.75～1.0m×2.5m篱架或0.75～1.0m×3.0m的小棚架。

Effects of different vine space and row space and trellis on fruit quality and yield were studied with grape varieties of ＂Shuanghong＂, ＂Shuangyou＂ and ＂Zuoyouhong＂ of Vitis Amurensis Rupr. as materials. The results showed that the vines with vine space and row space of 0.75m ×2.5m - 3.0m had earlier flowering date and high-yield period, higher fruit setting rate, lower fruit dropping rate, lower total acid content, higher sugar content and yield in both fence trellis and booth trellis. The optimal vine space and row space were 0.75m - 1.0m ×2.5m in fence trellis and 0.75m - 1.0m × 3.0m in booth trellis respectively for the three ain-planted grape varieties of Vitis Amurensis Rupr..
