| 中文摘要: |
| 运用纺锤形树型实现宽行密植栽培作为现代梨园的主要生产模式，已经为广大果农所接受。生产实践中，步入老龄期的梨园更新复壮已经成为现代梨园经营面临的新课题。为此，笔者结合在费县薛庄镇开展的老龄梨园改造工作，提出了目标树型（圆柱形）、合理负载、土壤改良、科学灌溉、行间生草、树盘覆盖等系列技术措施，实现了老龄梨园的持续优质、稳产、丰产。 |
| 英文摘要: |
| As the main production mode of modern pear orchards, using spindle tree type to realize wide row and high density cultivation has been accepted by the majority of fruit farmers. In production practice, the renewal and rejuvenation of pear orchards in the aging period has become a new topic for modern pear orchards. For this reason, the author put forward a series of technical measures such as target tree type (cylindrical), reasonable load, soil improvement, scientific irrigation, intercropping grass, tree cover, etc., in combination with the transformation work of the aged pear orchard carried out in Xuezhuang Town, Feixian County, to achieve the sustainable high-quality, stable and high-yield of the aged pear orchard. |
