The effects of mineral nutrition on fruit cracking rate of Litchi chinensis are studied in this paper through determining the mineral nutrients in the leaves and pericarp of lychee and in soil. Results show that the contents of Ca, Mg and B in leaves of lychee, the N/K ratio in pericarp, and the N/K ratio, contents of organic matter and exchangable Ca in soil influence the cracking rate.%通过对糯米糍荔枝叶片、果皮、土壤中矿质元素含量的研究，探讨矿质营养对荔枝裂果率的影响。初步探明糯米糍荔枝叶片中的钙、镁、硼含量，果皮中的氮钾比，以及土壤中的N/K比、有机质、交换性钙含量影响其裂果率。
