胶树叶蓬物候对胶园的管理有着不可低估的作用。过去,由于叶病防治的需要,植保工作者对第一蓬叶的物候,作了大量的观察与研究,但由于条件的限制,很少定量地研究影响物候的因子,并只侧重于第一蓬叶。随着对橡胶树物候与产量关系的认识不断加深,橡胶栽培和割胶工作者对叶蓬物候也越来越感兴趣,并相应进行了观察和研 Polyfoil leaves Phenology on the management of rubber plantation has a role to be underestimated. In the past, due to the need of leaf disease prevention and control, plant protection workers made a lot of observations and studies on the phenology of the first Puffy But due to the restriction of conditions, it is rare to quantitatively study the factors that affect phenology and only focus on the first Puffy leaves. With the increasing understanding of the relationship between rubber tree phenology and yield, rubber growing and tapping workers are also increasingly interested in the leaf phenology of Ye Peng.
