| 中文摘要: |
| 针对广西早期引进的凤梨释迦老龄果树存在低产、裂果、果品不佳等问题，重点通过树形改造和产期调节技术，对十年生以上凤梨释迦大树进行了低产改造试验研究。研究结果实现了老龄树形结构优化，促进树冠透风透光，均衡树体营养供应，为轻简化栽培管理提供了便利；结合人工授粉和产期调节，显著提高了坐果率、改善果品质量，提高单产。本改造技术实施对提升凤梨释迦老果园产量和品质以及生产效益具有重要指导意义。 |
| 英文摘要: |
| In view of the problems of low yield, fruit cracking and poor fruit quality in the early introduction of atemoya in Guangxi, The low-yielding experiment of atemoya which over ten years old was carried out by pruning and perinatal regulation. The results showed that the tree structure was optimized, the tree crown was ventilated and transparent, the nutrition supply was balanced, and the cultivation management was simplified, and through artificial pollination and maternity reconciliation, the fruit setting rate, fruit quality and single plant yield were increased significantly. This reconstruction technology can improve the yield, the quality and the production efficiency of the atemoya old orchard. |
