早熟荔枝三月红主要分布在桂南和桂东南地区。一般２月上旬开花，５ 月上、中旬收获。花期处于一年当中最低温度季节，这一时期的植株营养状况对花器官发育和座果产生最大的影响。而秋梢叶片的营养水平则可在一定程度上反映花期植株营养状况。１９９７～１９９９ 年，以三月红为代表，分析早熟荔枝的营养变化，丰产性植株秋梢老熟功能叶Ｎ 的含量为１９１１％ ～２２８５％ ，Ｐ２Ｏ５为０４５５％ ～０５８７％ ，Ｋ２Ｏ 为１２９２％ ～１６４８％ ，Ｎ∶Ｐ２Ｏ５∶Ｋ２Ｏ＝ １∶０２２９～０２５７∶０６４９～０７２１。可以以此为依据，指导早熟荔枝施肥 Premature lychee March red mainly in southern Guangxi and Guangxi southeast. Generally early February flowering, May, mid harvest. The flowering period was the lowest in one year. The vegetative state of plants in this period had the greatest influence on floral organ development and fruit setting. However, the nutrition level of autumn shoots can reflect the nutritional status of flowering plants to a certain extent. From 1997 to 1999, with the March red as the representative, the nutrition changes of early mature litchi were analyzed. The content of N in the mature leaves with high yield was 1911% ~2285%, and the P2O5 was 0455% ~ 0  587%, K2O is 1292% ~ 1488%, N:P2O5:K2O is 1:0229 ~ 0257:0649 ~ 0721. Can be used as a basis for early precocious litchi fertilizer
