2006年对榅桲物候期进行了观测,结果表明,榅桲叶芽和花芽的萌动需要≥10℃以上的积温分别为120℃和140℃以上;枝条和果实生长发育有3个生长高峰,果实的生长曲线是双S形,前期横径大于纵径,7月下旬后纵径大于横径。根据榅桲枝、果的生长发育规律,加强土肥水管理和树体管理,改善通风透光条件,可提高产量和果实质量。
In 2006, the phenophase of Emu was estimated. The results showed that the accumulated temperature of ≥10 ℃ and above were required for germination of leaf buds and flower buds, respectively. The accumulative temperatures were above 120 ℃ and 140 ℃, respectively. The growth and development of shoots and fruits had three growth peaks. Growth curve is double S-shaped, pre-transverse diameter greater than longitudinal diameter, late July after longitudinal diameter greater than the transverse diameter. According to 榅 桲 branches and fruits of the law of growth and development, strengthen soil and water management and tree management, improve ventilation and light conditions, can increase yield and fruit quality.
