摘　　要：【目的】探讨低纬度高海拔地区纽荷尔脐橙果实生长发育规律及其与气温、降水量和光照等气象因子的相关性,为广西低纬度高海拔地区纽荷尔脐橙高产优质栽培提供依据。【方法】以广西百色市靖西县南坡乡荷朗村种植的纽荷尔脐橙品种为试材,定期测定其果实纵、横径,运用Logistic方程模拟果实体积增长指标与生长时间的关系式,分析果实体积增长与气温、降水量和光照的相关性。【结果】纽荷尔脐橙果实纵、横径在果实整个生长过程中出现3个明显的生长高峰期,呈单S形曲线增长;Logistic拟合模型的相关系数均达极显著差异水平（P〈0.01）。8月下旬至9月上旬是纽荷尔果实生长的最大效能期;4~11月果实逐月净生长量与气温、降水量和光照变化呈显著正相关（P〈0.05）。低纬度高海拔地区纽荷尔脐橙表现果大,单果均重278.7g、果形指数0.96、可溶性固形物含量11.15%、可滴定酸含量3.58 g/100 m L、固酸比3.10∶1、糖酸比2.90∶1。【结论】广西低纬度高海拔地区纽荷尔脐橙果实生长动态变化可运用Logistic方程模型拟合,其果实的生长发育与气温、降水量和光照有密切的相关性。生产中可在纽荷尔脐橙果实迅速膨大时期（8~9月）利用当地有利的气温、降水量和光照等气象条件促进果实更好地生长发育,改善果实品质。[Objective]In order to provide the basis for high yield and quality cultivation techniques of Newhall navel orange fruit in low-latitude and high-altitude areas of Guangxi, the correlation of temperature, precipitation, sunlight and other meteorological factors with growth and development laws of Newhall navel orange fruit in low-latitude and high-alti- tude areas was investigated. [Method]Taking Newhall navel orange from Helang village, Nanpo township, Jingxi country, Baise city of Guangxi as materials, the vertical and horizontal diameters of fruit were regularly measured, and then Logis- tic equation was establish for fitting relationship between fruit volume growth index and growth time to analyze correlations between fruit volume growth and temperature, and between precipitation and sunlight. [ Result]The results showed that vertical and horizontal diameter of Newhall navel orange fruit had 3 obvious growth peaks during the whole growth and de- velopment process, presenting growth of single S-shaped curve. The correlation coefficient of Logistic fitting model reached a very significant level （P〈O.01）. the fruit growth was the most efficiency from late August to early September. The monthly net growth of fruit from April to November showed significantly positive correlation with temperature, precipitation and sunlight （P〈0.05）. Newhall navel orange fruit in low-latitude and high-altitude area was characterized by big fruit, single fruit weight of 278.7 g, fruit shape index of 0.96, soluble solid content of 11.15%, titratable acid of 3.58 g/lO0 mL, TSS-Acid ratio of 3.10：1 and sugar-acid ratio of 2.90：1. [Conclusion]The growth dynamic changes of Newhall navel orange fruit in low-latitude and high-altitude areas of Guangxi can be fitted using the Logistic equation model, and the growth and development of the fruit was closely associated with temperature, precipitation and sunlight. The fruit growth and develop- ment can be promoted by taking advantage of meteorological conditions during fruit en
