枇杷因立地条件差,管理粗放,或栽植实生苗、劣种苗,常出现树体未老先衰,产量低、品质差,须进行综合改造。枇杷未老先衰树和劣种树的综合改造应先从地下部改造开始,然后再行地上部改造,否则将会影响枝梢生长,延迟结果。在本地连续2年对不同地点的枇杷进行综合改造,具体是先于9月底进行扩穴点土,下一年立春进行高接换种,一年后（2月）调查一年梢生长量平均为92.4厘米,茎粗直径（接口顶3厘米处,下同）2.6厘米,2年后（2月）调查2年梢生长量平均为171.2厘米,茎粗直径平均4.2厘米,分
Loquat due to poor site conditions, extensive management, or planted seedlings, inferior seedlings, often appear before the first aging tree, low yield, poor quality, to be comprehensive transformation. Loquat is not the first old and poor tree comprehensive transformation of the transformation should start with the underground transformation, and then re-line the upper transformation, otherwise it will affect the shoot growth, delay the results. In the local continuous 2 years of loquat in different locations to conduct a comprehensive transformation, in particular, is the first point in late September to expand the hole, the next year in spring high replacement, a year later (February) a year shoot growth average Is 92.4 cm, stem diameter (interface top 3 cm, the same below) 2.6 cm, 2 years later (February) survey 2 years shoot growth average 171.2 cm, stem diameter average 4.2 cm, points
