摘  要：
【目的】探讨产期调节栽培条件下四季蜜龙眼根系生长和地上部生长的关系,为该品种的栽培管理提供理论依据。【方法】以4年生四季蜜龙眼为材料,采用根窖法研究产期调节栽培条件下四季蜜龙眼根系一年内的生长动态,探讨根系生长与地上部新梢生长、开花和结果的相互关系。【结果】四季蜜龙眼根系一年有两次生长高峰:3月下旬～4月下旬出现第1次根系生长高峰,第2次生长高峰出现在7月下旬～9月中旬,根系生长活动与土温有密切关系;新梢加长在一年中也有两次生长高峰,3月底出现第1次生长高峰,5月上旬出现第2次生长高峰,并持续到下旬。【结论】产期调节栽培下的四季蜜龙眼新梢、果实和根系的生长有交替现象。

摘  要：
[Objective]Relationships between the growth of root system and aerial part in Sijimi longan by regulating cultivation conditions were studied to provide references for its cultivation management. [Method]The growth trend of root system of four-year-old Sijimi longan in a year under regulated cultivation conditions was observed by using root cellar method. Relationships between root system growth and new shoot growth, flowering and fruiting were assayed. [Result]Root system began to grow in late January, and two peaks appeared during its growth in one year, one appeared during late March and late April, the other one appeared during late July and mid September. New shoot growth also had two peaks in a year, one was in late March, and the other one was in May. [Conclusion]The growth of shoot, fruit and root system in Sijimi longan overlapped with each other under the regulated cultivation conditions.
