2005—2009年,在甘肃省靖远县进行枣树窄纺锤形树形的整形修剪试验,结果表明,在当地枣树选用窄纺锤形早期产量高、树体小、生产的枣果实品质好等优点;窄纺锤形枣树栽植密度比自然圆头形树形枣树高50%,木质化枣吊的数量比自然圆头形树形树高15%～30%;定植后第1～5年单位面积累计产量比自然圆头形树形树高22.5%,产值比自然圆头形树形树提高27.7%。
2005-2009, Jujube County, Gansu Province, narrower spindle-shaped tree pruning test, the results show that the selection of narrow spindle spindle jujube early high yield, small tree, jujube fruit production quality is good Advantages; Narrow spindle-shaped jujube planting density than the natural round-shaped tree jujube tree 50%, the number of lignified jujube hanging than the natural round-shaped tree tree 15% to 30%; 1 to 5 years after planting The cumulative yield per unit area was 22.5% higher than the natural round-shaped tree and its output value increased by 27.7% over the natural round-shaped tree.
