摘要
以赤霞珠葡萄为试材,研究了1-4 a生结果母枝剪留长度对其萌芽及结果的影响。结果表明：栽植第1年的整形期间,母枝粗度（直径）为0.70-0.79 cm时宜剪留约70 cm,母枝粗度为0.80-1.00 cm时宜剪留约80 cm;2 a生时,母枝粗度0.70-1.20 cm,在母枝数量够用时剪留4-5节综合效果较好,若母枝量不足则可适当长剪留;3 a生时,母枝粗度0.80-1.25 cm,剪留长度以3~6节综合效果较好;4 a生时,结果母枝剪截部位粗度1 cm,剪留长度6-8节为宜。
The effects of length of 1-4 year old maternal branch pruned on the sprouting budding and fruiting of Cabernet Sauvignon grape were studied.The results showed that the suitable branch lengths of 1 year old grape were about 70 cm and 80 cm with the branch diameters of 0.70-0.79 cm and 0.80-1.00 cm,respectively.The suitable branch length of 2 year old grape should be remained 4-5 nodes with the branch diameters of 0.70-1.20 cm,that of 3 year old grape should be remained 3-6 nodes with the branch diameters of 0.80-1.25 cm,and that of 4 year old grape should be remained 6-8 nodes with the branch diameters of 1.00 cm.
