中文摘要：以3个湛江地区甘蔗生产种植品种粤糖79/177、新台糖10号和粤糖71/210为材料,通过分期下种的大田试验,研究湛江地区不同植期甘蔗的糖分积累,建立相应的数学模型,探讨湛江市甘蔗上下节锤度比与糖分关系。结果表明,各品种各植期到达各上下节锤度比值0.95的日期,均早于到达最高糖分日期,粤糖79/177为37～80d,新台糖10号为33～86d,粤糖71/210为37～64d。糖分相比也有一定的差距,各品种分别少0.55～1.92,0.55～2.07,0.58～1.25。

外文摘要：Three sugarcane cultivars commercially grown in Zhanjiang (Yuetang 79/177, Yuetang 71/210 and Xintaitang 10) were planted at five different dates at 20-day intervals in a field experiment. Using correlation analysis, simulated by conic regression equation, mathematical model were established for sugar accumulation in the plants at different dates. A Brix ratio of 0.95 of the upper and lower parts of the sugarcane was reached 37, 33 and 37 days after planting in the above-mentioned cultivars, respectively, while highest sugar content occurred 80, 86 and 64 days after planting.
