对双行矮化超密度骏枣(Ziziphus jujuba cv.Junzao)园“三五九”树形和“小冠疏层形树形”2种树形产量、品质、经济效益方面进行对比试验。结果表明,“三五九”树形保持了枣树的密植状态,增加了果园空间利用率,“小冠疏层形”树形扩大了果树的结果面积,但在密植情况下不利于果树的通风透光;“三五九”矮化密植修剪,三五九“树形修剪技术能较大幅度地提高特级果和一级果的比例,但总体产量下降,”小冠疏层形“树形座果早晚基本一致(早座果时间为7月5日左右),枣果大小差异小、较均匀整齐,无畸形果、单位产量较高,但果品质量较差;”三五九“夏季修剪技术比”小冠疏层形“修剪技术用工多,费用高。
The yield, quality and economic benefit of two kinds of trees of Ziziphus jujuba cv. Junzao garden, ”359“ tree and ”small crown sparse layer tree“ Comparative Test. The results showed that the trees of ”359“ maintained dense state of jujube trees and increased the utilization rate of orchards, and the tree shape of ”spruces of small crowns“ enlarged the fruit tree area, but in close planting Is not conducive to the ventilation and light of fruit trees; ”359 “ dwarf and close planting pruning, 359 ”tree pruning technology can significantly improve the proportion of special grade fruit and a fruit, but the overall output decreased, “Small crown sparse layer ” tree-shaped fruit is basically the same morning and evening (early fruit time is July 5 or so), jujube fruit size difference is small, more uniform, without deformity fruit, the unit yield is higher, but the fruit quality Poor; “359 ” summer pruning technology than “small crown sparse layer ” pruning technology and more labor, high cost.
