摘要
以结果习性好、经济效益高的立冬本龙眼为试材,研究不同果穗留量对果实品质、营养枝质量及产量效益的影响。结果表明,每穗留果60～70粒,果穗数量以32%最为适宜,果实单果重13.07～13.33 g的优质果;营养枝粗度7.78～8.46 mm、长度23.78～26.35 cm、复叶数16.86～19.60个之间,次年枝梢成花率为71.04～77.13%,与对照树一样为优良结果母枝。其次果穗留量38%略为偏多,果穗留量28%略为偏少,果穗留量42%和48%容易出现大小年或隔年结果。
The effects of different reserved fruit amount on fruit quality,vegetative shoot quality and output benefit in Longan ’Lidongben’ were studied in this paper The results showed that 60~70 reserved fruit amount and 32% fruit cluster number was the most suitable,with these conditions the single fruit weight was between 13.07～13.33 g,vegetative shoot coarseness was between 7.78～8.46 mm,vegetative shoot length was between 23.78～26.35 cm,compound leaf number was between 16.86～19.60 and the next year flower formation rate of shoot was 71.04～77.13%,which were similar to the CK（fine bearing basal shoot）.The reserved fruit amount was a little higher for production at 38% and was a little lower at 28%,the reserved fruit amount which was at 42% and 48% would lead to alternate bearing.
