【摘要】 以20年生大红袍为试材,研究中果型枇杷(Eriobotrya japonica)以叶定果的留果量技术。结果表明,中心枝结果母枝按叶果比3∶1定果,留果数2~6个,侧生枝结果母枝和采果痕枝结果母枝按叶果比4∶1定果,留果数2~4个,可获得92%左右的等级果,平均单果重33.4 g,果实大小均匀,外形美观,着色良好,单果重在30 g以上的特级果和一级果约占50%,二级果和三级果约占40%。更多还原

【Abstract】 Using 20-years old Dahongpao loquat as material, the technique of setting fruit based on the tree leaves of medium-fruit loquat(Eriobotrya japonica) was studied. The results showed that if the leaf-fruit ratio was 3∶1 for center flowering branches with 2~6 fruits on each branch, and the leaf-fruit ratio for lateral flowering branches and picking mark flowering branches was 4∶1 with 2~4 on each branch, 92% of the harvest would reach graded fruits with average weight of 33.4 g, evenly size, good appearance and fine color. The ratio of special-grade and first-grade fruits with single fruit over 30 g was about 50% while the ratio of second-grade and third-grade was about 40%.更多还原
