摘要
本文提出了龙眼“结果母枝单元”的概念；阐述了龙眼枝梢能否演变成良好的结果母枝，就其内因来说，是由结果母枝单元的状况决定的；指出石硖龙眼优良结果母枝单元的生长量指标为基部直径０．８ｃｍ以上、复叶数１５张以上，这样的枝梢一般为三次或三次以上梢组成；并进一步指出，适当疏花疏果、夏季修剪，促生秋梢结果母枝的基枝以及加强肥水管理是培养优良结果母枝单元，实现丰产稳产的关键措施。
This paper presented a new concept called “the basic branch unit of bearing shoot of Longan” and explained that whether or not a longan branch will develop into a good basic branch of bearing shoot is determined by the inner condition of the basic branch unit. The study shown that a good basic branch of bearing shoot of cultivar Shixia is a branch with a growth more than 08cm in diameter at the base of the branch and have more than 15 leaves. This type of branch is normally composed of 3 or more flushing growth. The paper also pointed out that the key measures to gain high and regular yield of Longan are raising well developed basic branch unites of bearing shoots by appropriate flower and fruit thinning and summer prunning to promote a flush which will become a basic growth for autumn flush and improving the management of fertilizer and water.
