| 以“北陆”蓝莓为试验材料，采用生产区限根方法，对限根后蓝莓的株高、冠幅、枝类组成、干茎、新梢伸长和果实品质等指标进行分析，研究限根栽培对蓝莓幼树树冠生长和果实品质的影响。结果表明：限根栽培在定植后前两年显著促进植株的直立生长，与对照相比分别增加11.7%和14.6%；定植后限根植株的冠幅均受到抑制，其抑制效果在限根处理后的第三年更为显著；限根栽培显著改善了果实的品质，其果实单果重和可溶性固形物的含量增加幅度最高可达28.8%和13.6%，对果型指数影响较小。 |
| 英文摘要: |
| Taking the blueberry （Vaccinium Spp）“Northland”as materials ,The production area is used to limit root zone. The height of the tree，the diameter of the canopy,type of fruiting branches,trunk diameter,growth dynamic of new shoot and fruit quality were measured. The result showed that this method restriction dramatically increase the height of the tree in the first two days.compare to the control, the increase was 11.7% and 14.6% . After planting ,the diameter of the canopy was dramatically inhibited, The inhibit effect was more dramatically in the third year. Root restriction improve fruit quality dramatically, namely per fruit weight (28.8%) ,soluble solid content (28.8%). However, root restriction did not have a strong effect on fruit shape index. |
