- 摘要:
- 以盛果期郁闭红富士苹果园为研究对象，以“长富2”苹果为试材，采用高干开心形与低干开心形2种树形改造方法，研究了红富士苹果郁闭园树形改造、株行距改造、整形修剪等措施对“长富2”苹果生长结果的影响。结果表明：红富士郁闭园通过改造后，采用高干开心形，“长富2”苹果主干变高，树高降低，冠径扩大，骨干枝数量减少；枝条总量减少，单株枝量增加，长枝比例减少，优质短枝比例增加；单果重提高，果形指数略有加大，直径80 mm以上果实比例增加，果实普遍增大；着色面积1/2以上果实比例显著提高，部分果实全面着色；果实可溶性固形物含量有所增加，可滴定酸含量、维生素C含量变化不大，果实硬度有所提高。
- Abstract:
- Taking high density Fuji apple with flourishing garden as research object,and ‘Changfu 2’ as the test material，by the method of high trunk open centre shape and low trunk open centre shape techniques，the effect of high density canopy renovation，reconstruction spacing，pruning and other measures on Fuji apple garden and fruit of ‘Changfu 2’ apple were studied.The results showed that through the transformation to Fuji apple garden，by use of high trunk open centre shape,the height of trunk bacame higher and tree height became lower，crown diameter expanded，the number of backbone branches reduced,the total branches reduced，branches per plant increased，long branch proportionally reduced by increasing the proportion of high-quality spur；fruit weight inereased，fruit shape index slightly increased，the proportion of more than 80 mm diameter increased，fruit generally increased；the proportion of colored area of 1/2 or more significantly increased soluble solids content inereased，titratable acid content，vitamin C content changed little，firmness increased.
