摘要： 对宁陵“金顶谢花酥梨”幼树干粗与果实大小、品质、留果量、花芽形成的关系进行了研究，结果表明，酥梨在密植条件下，幼树树干横截面积与留果量及产量呈显著正相关，每平方厘米横截面积负载量为450～750g时，即折合每平方厘米干断面积留果2～3个时，果实大小和品质最佳，花芽形成率最高(51.70%～56.20%)，翌年开花量适中，且果实商品性能良好。

Abstract: The study on the correlation between trunk diameter of young tree and fruit size, fruit quality, reserved fruit amount and flower-bud formation in Jinding Xiehua Suli grown in Ninglin county shows that a significantly positive correlation exists between the cross -sectional area of young tree trunk and the reserved fruit amount and fruit yield in Suli under the condensed planting.When the load amount in 1 cm2 cross-sectional area is 450-750g(i.e.2-3 fruits are reserved in 1 cm2 cross-sectional area) the fruit size and fruit quality are optimum, the flower formation rate is highest (51.70-56.20%),the flowering amount is middle next year and the commercial property of the fruit is well.

Key words: Jinding Xiehua Suli, Trunk diameter of young tree, Load amount of tree, Correlative analysis
