甘蔗新品种园林17号在广西蔗区的栽培适应性研究

Study on Adaptability of Sugarcane Variety Yuanlin 17 in Guangxi Sugarcane Area

以当地主栽品种新台糖22号、新台糖16号为对照,在广西5个不同生态蔗区开展甘蔗新良种园林17号1年新植蔗、1年宿根蔗栽培适应性试验,研究园林17号主要农艺性状和经济性状在不同生态蔗区的综合表现,为加快园林17号的繁殖和推广提供参考。结果表明:园林17号的萌芽率、分蘖率、宿根发株数、有效茎数、茎径、单茎重等性状均优于对照,蔗糖分稍低于对照,平均蔗茎产量7419.0m2/667m2、亩含糖量1078.4m2/667m2,分别比对照提高14.81%、12.52%。应用模糊评分法作综合评判结果,园林17号春植蔗、宿根蔗主要农艺性状和经济性状在不同生态蔗区的综合表现均优于对照,在桂中、桂中北蔗区较对照品种的优势比桂南、桂东、桂西蔗区更明显。因此,园林17号适宜在广西各主要蔗区推广种植,尤以在桂中、桂中北蔗区的应用推广潜力更大。

The adaptability tests of new sugarcane variety Yuanlin NO. 17 were conducted in five different ecological sugarcane areas of Guangxi. In the test, Yuanlin NO. 17 was planted for 1 year new planting sugarcane and 1 year ratoon, ROC 22 and ROC 16 as control. The results showed that, except the sugar content, Yuanlin NO. 17 were better than the controls in germination rate, growth rate, shoot number of ratoon, effective tiller, stem diameter, weight of single stem. The average sugarcane stem yield was 7419.0 m^2 / 667 m^2, sugar content of 667 m^2 was 1078.4 kg, which increased by 14.81% and 12.52%, respectively, compared with the controls. Comprehensive performances in agronomic characters and economic characters of Yuanlin NO. 17 in new planting sugarcane and ratoon in different ecological sugarcane areas were better than the controls. The superiority of Yunlin NO. 17 to the controls in the center, north center sugarcane areas of Guangxi is greater than that in the southem, eastern and western sugarcane area of Guangxi. Therefore, Yuanlin 17 is suitable for different sugarcane areas in Guangxi, especially in the north, northern center sugarcane areas.
