Introduction and Promotion of Yunzhe081609 in Dehong Sugarcane Area

云蔗081609于2012年引入德宏州,为进一步探讨该品种在德宏蔗区推广应用潜力,通过多年多点试验示范种植和甘蔗生产调研,总结云蔗081609在德宏蔗区的推广应用概况、种植经验及经济效益。结果表明,该品种表现为早熟(11月甘蔗蔗糖分为14.02%)、高糖(全期平均甘蔗蔗糖分为16.20%)、高产(114 t/hm^(2)),生势好、株型直立、抗倒伏,宿根丰产稳产;品质好,重力纯度高,纤维分适中,还原糖低等优良性状,具有良好的推广应用前景。2017年该品种在德宏州小面积种植示范,2018年在德宏州蔗区推广应用;2024年种植推广面积达19941 hm^(2),2019~2024年累计推广面积40273 hm^(2),产生了较大的经济效益、社会效益、生态效益,具有良好的推广应用前景,成为德宏州蔗区早熟种主推品种之一。

Yunzhe081609 was introduced to Dehong Prefecture in 2012.To further the potential of this variety for promotion and application in the Dehong sugarcane area,we conducted multi-year and multi-site trials and demonstration plantings,surveyed sugarcane production to summarize the promotion and application status,planting experience,and economic benefits of Yunzhe081609 in Dehong sugarcane area.The results showed that this variety was characterized by early maturity(sugarcane sugar content of 14.02 in November),high sugar content(average sugarcane sugar content of 16.20% over the entire period),high yield(114 t/hm^(2)),good growth momentum,straight plant type,resistance to lodging,and stable high yield in subsequent crops.It also had good quality,high specific gravity,moderate fiber content,and low reducing sugar,which were excellent traits,and had a good prospect for promotion and application.In 2017,this variety was demonstrated in small-scale planting in Dehong Prefecture,and it was promoted and applied in the areas of Dehong Prefecture in 2018.In 2024,the planting and promotion area had reached 1941 hm^(2),and the cumulative promotion area from 2019 to 2024 was 40273 hm^(2).It has generated significant economic,social,and ecological benefits,with good prospects for further promotion and application.It has become one of the main early-maturing varieties recommended the sugarcane areas of Dehong Prefecture.
