脐橙果实在迅速膨大前期发生脐部黄化(简称脐黄)而导致严重落果,是脐橙类品种所特有的低产原因,它因品系、树龄、气候以及栽培管理水平不同而异,幼龄初投产树尤甚。随着柑桔品种结构的调整,脐橙的迅速发展,幼树的陆续投产,因脐黄而落果日趋突出。针对这一问题,采用中国农科院柑桔研究所提供的新型植物生理活性剂——FOWS防止脐黄,取得良好效果。
Navel orange fruit in the rapid expansion of the umbilical yellow (umbilical yellow) and lead to serious fruit drop, is a species of navel oranges due to low yield, which because of strains, age, climate and cultivation and management of different levels, early childhood production Especially the tree.
