甜樱桃“V”字型栽培模式幼树整形修剪技术研究

Research on the Pruning Method of Young Sweet Cherry Tree of 'V' Cultivation Pattern

以栽培密度(宽窄行)分别为3m×(0.8+3.0)m、3m×(1.0+3.0)m及3m×(1.2+3.0)m的"V"字型栽培模式下2a生樱桃幼树为试材,采取剪留65、75及85cm短截及刻芽处理,分析了3种种植密度与3种短截处理下新枝的数量、长度及粗度差异;测定3种种植密度下刻芽新枝长度与粗度,并与常规大田栽培的细长纺锤形为对比。结果表明:"V"字型模式幼树轻截更能促发中庸枝,且发枝数量较大;3m×(1.2+3.0)m下的"V"字型模式幼树与3m×4m细长纺锤形刻芽生长量相当。

Taking bud-notching and cutting back with the remaining branch length which were 65 cm,75 cm and 85 cm to the 2 years old cherry trees as materials, these cherry trees were cultivated as ‘V＇ cultivation pattern with narrow and wide row which were 3× （0. 8＋3. 0）m,3× （1.0＋3. 0）m and 3× （1.2＋3. 0）m respectively. The new branch＇s quantity, stem diameter and length after cutting back and bud-notching were analyzed. The stem diameter and length comparison was made between ‘V＇ cultivation pattern with wide and narrow row and normal field cultivated slender spindle. The results showed that cutting back slightly could branch the most new short branch. The branch increment on bud-notching of ‘V＇ cultivation pattern with the density as （1.2＋3. 0） m was equal with that on slender spindle as （3×4）m density.
