欲增大果实体积,具有显著效果的主要方法是喷布激素和环剥,已有研究发现,环剥对果实大小的影响比喷布2,4-D更为显著。本试验试材为树龄15—20年的马叙无核葡萄柚、沙莫蒂甜橙和伏令夏橙。采用两种环剥工具,一种是随着移动即可剥掉预定宽度树皮的U形刀,另一种是Yuran刀(以色列专利49772号),后者不剥掉
To increase the volume of fruit, the main method that has a significant effect is spraying hormones and girdling. It has been found that the effect of girdling on the fruit size is more significant than spraying 2,4-D. The test material for the age of 15-20 years of Ma Xu non-grapes grapefruit, Chamoid orange and Valsparum orange. Two types of girdling tools are used, one is a U-shaped knife that can be peeled off with a predetermined width as it moves, and the other is a Yuran knife (Israel Patent No. 49772) which does not peel off
