Abstract: Qingzhen No.1 has strong dryness, good affinity, dwarfing ability and cold tolerance, and is suitable for medium density cultivation under plant spacing of (1.2~2.0)m×(3.5~4.0)m. Qingzhen No.1 was managed by high spindle tree structure under medium density cultivation conditions. From the aspects of shaping and pruning, flower and fruit management, fertilizer and water management, the key technologies of ‘controlling treevigorous and promoting flowers, early fruit and pressing crown’ were summarized for planting reference.
