摘　　要：为了研究南繁条件下四季蜜龙眼引种生长发育的表现,本文分析了南繁区生态特性,测定夏梢生长动态和成熟果实大小、可溶性固形物含量等指标,建立枝梢生长数据模型。研究表明,四季蜜龙眼引种到南繁区种植后,植株生长旺盛,每年可抽梢4~6次,自然开花4~6批次,其夏梢生长动态呈单S型曲线,适宜在南繁区生长。南繁区气候数据调查和枝梢生长发育动态及其数学建模可为制定四季蜜龙眼反季节栽培模式和南繁育种提供理论参考,为进一步利用南繁气候特性进行南繁育种和制定南繁区反季节栽培模式提供理论依据。To study growth and development performance of Sijimi longan during introduction in off-season breeding,in this paper,ecological characteristics of off-season breeding area are analyzed;growth dynamic of summer shoots,matured fruit size and soluble solid content were determined to establish model of shoot growth data.The results showed that Sijimi longan grew well after being introduced into off-season breeding area,annually sprouted 4-6 times,blossom 4-6 times,and its summer tip grew following a single S-shaped curve,which was suitable for growing in off-season breeding area.The investigation of climate data,dynamics of shoot growth and development and mathematical model in off-season breeding area can provide theoretical reference for formulating off-season cultivation model of Sijimi longan,providing theoretical basis for making further use of climate characteristics to conduct off-season breeding and establishing off-season cultivation model in the area.
