无人机喷施不同增糖剂对甘蔗产量和糖分的影响

Effect of Different Sucrose Promoter Sprayed by UAV on Cane Yield and Sucrose of Sugarcane

在粤北蔗区以“粤引11”和“粤糖94-128”为试验甘蔗品种,通过无人机喷施6种不同的甘蔗增糖剂,研究其对甘蔗产量和糖分的影响。研究结果表明:各种增糖剂对两个品种甘蔗产量无显著影响,而对蔗糖分具有提升作用,且降低还原糖含量,同时对宿根发株率无显著影响。其中4号增糖剂(中微量营养元素液体肥)和5号增糖剂(氨基酸液体肥)对于两个甘蔗品种的含糖量提高幅度最大,特别是对于YT94-128,喷施30 d后,4号增糖剂和5号增糖剂比对照甘蔗含糖量分别提升9.03%和12.64%,喷施60 d后,4号增糖剂和5号增糖剂比对照甘蔗含糖量分别提升7.80%和9.87%。

Using “Yueyin 11” and “Yuetang 94-128” as experimental varieties, six different sucrose promoters were sprayed by UAV to study the effect of sugarcane yield and sucrose. The results showed that all kinds of sucrose promoter had no significant effect on the yield of two varieties of sugarcane, while they increased the sucrose content, reduced the content of reducing sugar, and had no significant effect on the rate of ratoon seedling emergence. No. 4 and No. 5 sucrose promoter increased the sugar content of the two sugarcane varieties more significantly, especially for YT94-128, the sugar content of No. 4 (Medium and micro nutrient liquid fertilizer) and No. 5 (Amino acid liquid fertilizer) sucrose promoter increased by 9.03% and 12.64% respectively after spraying for 30 days, while after spraying for 60 days, the sugar content increase of No. 4 and No. 5 sucrose promoter was 7.80% and 9.87%, respectively.
