摘要
以云瑞10和云瑞11系列的21个甘蔗品种(系)进行新宿栽培试验,收集2年新植、1年宿根每年11月至翌年3月的甘蔗蔗糖分及蔗汁重力纯度数据,分析该21个甘蔗品种(系)蔗糖分的变化规律和成熟情况。结果表明:在德宏蔗区,云瑞11-306、云瑞10-295、云瑞10-237、云瑞11-472、云瑞10-476、云瑞10-1072、云瑞10-669等7个材料属于早熟高糖品种(系),其中云瑞11-306、云瑞10-295为特早熟高糖种,在11月(或10月中下旬)砍收可获得较好的经济效益;云瑞10-498、云瑞10-187、云瑞10-1277、云瑞11-314、云瑞11-312为中晚熟种,可在2月安排入榨。3级成熟材料包括云瑞10-178、云瑞10-1325、云瑞10-1277,适合安排在12月或1月开榨。
The field experiment involved 21 sugarcane varieties belonging to Yunrui 10 and Yunrui 11 series and three crop years（two plant cane and one first ratoon）. Sucrose content and cane juice gravity purity data were collected and analyzed during November through March to reveal sucrose accumulation patterns and maturation stages. The results showed that In Dehong sugarcane pro-duction area, six varieties, namely, Yunrui 10-306, Yunrui 10-295, Yunrui 10-237, Yunrui 10-472, Yunrui 10-476,Yunrui 11-1072,and Yunrui 10-669 were early maturing and high sugar varieties. Yunrui 11-306 and Yunrui 10-295 were extremely early maturing and high sugar varieties,which produced good economic return when harvested from mid-October through November. Yunrui 10-498, Yunrui 10-187,Yunrui 10-1277,Yunrui 11-314,Yunrui 11-312 were for medium to late maturing varieties and could be harvested and pressed in February. Level 3 maturing varieties including Yunrui 10-278,Yunrui 10-169,Yunrui 10-1277,and Yunrui 11-314 were suitable for December or January harvest.
