摘　　要：为明确无人机喷施自主研发的新型增产增糖剂对甘蔗产量性状及品质的影响。本研究于2017~2019年在6个试验点开展试验,以当前广西主栽品种桂糖42号和柳城05-136为试验材料,设置无人机喷施新型增产增糖剂为处理组(T)、清水喷施为对照组(CK)。研究结果表明,无人机喷施增产增糖剂后甘蔗株高、单茎重、产量和节间数较对照分别提高8.32%、8.76%、11.99%和3.25%;无人机喷施新型增产增糖剂后甘蔗糖分、蔗汁重力纯度比对照分别高了0.78、2.57个百分点(绝对值),蔗汁还原糖分比对照低了0.1个百分点。无人机喷施增产增糖剂后能显著提高甘蔗株高、产量和糖分,降低蔗汁还原糖分和提高蔗汁重力纯度。In order to research the application effect of self-developed new sucrose-yield promoter on sugarcane,two main varieties Guitang42 and Liucheng05-136 were treated in this article.It set the spraying of new sucrose-yield promoter as the treatment(T)and water spraying as the control(CK)by unmanned aerial vehicle in 6 demonstration sites in Guangxi sugarcane growing areas from 2017 to 2019.The results showed that the plant height,single stem weight,yield,and internode number increased by 8.32%,8.76%,11.99%and 3.25%respectively after spraying the unmanned aerial vehicle with the sugar-increasing agent.The results of sugarcane quality analysis showed that the sugar content and gravity purity of sugarcane juice were 0.78 and 2.57 percentage points higher than the control respectively(absolute value)and the reducing sugar content of cane juice was 0.1 percentage point lower than the control.It could significantly increase the cane height and yield,and improve the quality by decreasing reducing sugar content and increasing sucrose content and gravity purity of juice by spraying new sucrose-yield promoter.
