摘要:

为了探索适宜山地甘蔗栽培的抗旱优良品种,解决山地甘蔗发展因干旱胁迫而面临着单产和糖分不高等问题,在云南省峨山县旱坡地实际栽培条件下,开展6个抗旱甘蔗品种(系)的种植比较试验研究,并采用蔗茎产量和蔗糖产量2个主要指标对甘蔗品种的抗旱性能进行分析评价。结果表明:‘德蔗03/83’、‘高海拔一号’和‘云蔗03/103’的抗旱性能较好(高产和高糖),3个品种的蔗茎产量依次为97.80、83.05、72.40 t/hm2,分别为对照种产量(‘新台糖22号’,88.16 t/hm2)的110.93%、94.20%、82.11%,蔗糖产量分别为11.01、11.30、10.58 t/hm2,比对照种的蔗糖产量(9.95 t/hm2)分别增产10.65%、13.57%、6.33%。因此,‘德蔗03/83’、‘高海拔一号’和‘云蔗03/103’可初步作为山地甘蔗的抗旱优良品种,其宿根性有待于进一步试验观察。

Abstract:

In order to provide the reference for selecting and extending the fine montane sugarcane varieties of drought-resistance, and further solve the problems (low sugarcane yield and sucrose content, etc.) of development of the montane sugarcane, comparative test of 6 drought-resistant sugarcane varieties (strains) were conducted on sloping dryland of Eshan County, and the author analyzed the drought resistance differences among sugarcane varieties. The results showed that the superior drought resistance (characterized by the high yield and high sucrose) for sugarcane were occurred in Dezhe03/83, Gaohaiba1 and Yunzhe03/103, which respectively presented the cane yield of 97.80 t/hm2, 83.05 t/hm2, 72.40 t/hm2, accounting for 110.93%, 94.20%, 82.11% of the comparison variety (ROC22, 88.16 t/hm2), and the respective sugar yield of 11.01 t/hm2 ,11.30 t/hm2, 10.58 t/hm2, increasing by 10.65%, 13.57%, 6.33% than the comparison variety (9.95 t/hm2). Therefore, Dezhe03/83, Gaohaiba1 and Yunzhe03/103 could be preliminarily considered as the fine montane sugarcane varieties of drought-resistance, and their ratoon need to be further experimental observation.
