摘　　要：粤糖60号是广州甘蔗糖业研究选育的优良甘蔗新品种,具有早熟、高产、高糖、农艺性状优良等特性。本试验在湛江蔗区研究3个植期对粤糖60号产量和蔗糖分的影响。结果表明:粤糖60号在湛江徐闻、遂溪和雷州等蔗区3个植期蔗茎产量都超过120 t/hm2,含糖量都超过20 t/hm2,蔗糖分都超过16%,农艺性状和经济性状显著优于ROC22。粤糖60号在徐闻和遂溪蔗区蔗茎产量达显著性差异,含糖量和蔗糖分差异不显著,徐闻蔗区蔗茎产量和含糖量均最高,遂溪蔗区蔗糖分最高。不同植期蔗茎产量和含糖量达显著性差异,蔗糖分差异不显著,其中12月份种植蔗茎产量、含糖量和蔗糖分均最高,2月份均最低。大面积种植试验结果表明,粤糖60号适合在徐闻、雷州和遂溪等蔗区种植。Yuetang NO.60 was bred by Guangzhou Sugarcane Industry Research Institute. It was an excellent sugarcane variety with desirable characteristics of early maturity, high cane and sugar yields, stable yield, good agronomic traits. The results of planting experiment of Yuetang NO.60 in different planting time in Xuwen, Suixi and Leizhou showed that the mean cane yield of Yuetang NO.60 was 120 t/hm2 above, sugar yield was all over 20 t/hm：, sucrose content was all exceed 16.23%, and most of agronomic characters and ecomic characters were significantly better than those of the check variety ROC22, respectively. The difference among cane yield of Yuetang NO.60 in different areas was significant while the difference among sugar and sucrose content was not significant. Cane yield and sugar yield in Xuwen were the highest while sucrose content in Suixi was the highest. The difference among the cane yield and sugar yield of Yuetang NO.60 in different planting time were highly significant while sucrose content was not significantly. Ecomic characters were the highest planted in December and the lowest was in February. The results of large area planting test indicated that Xuwen, Leizhou and Suixi were suitable for growing Yuetang NO.60.
