Abstract: Our studies carried out in 1983-1986 indicated that proper fertilizers promoted the development of autumn shoots and markedly increased the yield of ‘Shuizhang’ longan. There is a significant difference between cultivars in regard with their response to fertilizer.The response of ‘Shuizhang’ longan to fertilizer was more apparent than that of ‘Chike’ longan.The recommended optimum amount of fertilizers per bearing plant for ‘Shuizhang’ longan on the red soil hilly lands are:N, 1.24 kg, P₂O₅, 0.63 kg and K₂O, 1.15 kg. This will be available for reference in longan plantations.

摘要： 1983-1986年,作者开展了不同施肥水平对龙眼秋梢结果母枝及产量效应的研完。试验结果表明,适当增加施肥量可促进龙眼秋梢结果母枝的生长发育,且明显提高产量。研究结果还表明,不同品种对施肥的反应存在差异,水涨品种对肥料的效应较为明显,而赤壳品种则不明显。作者推荐,红壤丘陵地的水涨龙眼适宜的年株施肥量为:N1.24公斤,P₂O₅0.63公斤,K₂O1.15公斤。上列施肥水平可供生产上参考应用。
