摘要/Abstract

摘要： 以GT58甘蔗品种为试验材料,以叶面喷施清水为对照（CK）,使用自主研发的增产增糖剂叶面喷施,分析自然条件下和喷施增产增糖剂处理甘蔗上部、中部和下部节段糖分积累的变化规律。结果表明,在自然条件下,甘蔗生长至7~8节的下部节段糖分含量为7.05%,生长到20~22节糖分含量为13.24%,积累时长为100~110 d;甘蔗生长至11~13节,中部节段糖分含量为6.85%,生长到20~22节糖分含量为13.24%,积累时长为50~60 d;甘蔗生长至16~18节上部节段糖分含量为4.16%,生长到23~25节糖分含量为13.15%,积累时长为30~40 d;甘蔗节间生长至11~22节时的糖分积累量占全部积累量的63.9%。喷施增产增糖剂后,T₁（11~13节）到T₂（16~18节）时期甘蔗上部、中部和下部节段的糖分含量均低于对照;但到T₃（20~22节）时期,上部节段糖分含量高于对照,差异达显著水平,而中部节段和下部节段的糖分含量与对照差异不明显;到T₄（23~25节）时期,甘蔗上部、中部和下部节段的糖分含量分别比对照增加了0.96、1.04、0.93个百分点。

Abstract: Using GT58 sugarcane varieties as experimental materials, the foliar spray was applied with clear water as the control（CK）, and the self-developed yield and sugar-enhancing agent was used for foliar spraying. The changes of sugar accumulation in the upper, middle and lower nodes were analyzed under natural conditions and under spraying yield and sugar enhancers treatment. The results showed that under natural conditions, the sugar content in the lower segments reached 7.05% at the 7th to 8th nodes, and 13.24% at the 20th to 22nd nodes, with an accumulation period of 100 to 110 days; the sugar content in the middle segments was 6.85% at the 11th to 13th nodes and increased to 13.24% at the 20th to 22nd nodes, with an accumulation period of 50 to 60 days; in the upper segments, the sugar content was 4.16% at the 16th to 18th nodes and reached 13.15% at the 23rd to 25th nodes, accumulating over 30 to 40 days. Sugar accumulation from the 11th to 22nd nodes accounted for 63.9% of the total accumulation during the growth of internodes. After spraying the yield and sugar-enhancing agent, the sugar content in the upper, middle, and lower segments during the T₁ （11th to 13th node） to T₂ （16th to 18th node） period was lower than that of the control; however, by the T₃ （20th to 22nd node） period, the sugar content in the upper segments was significantly higher than the control, while the differences in the middle and lower segments were not significant. By the T₄ （23rd to 25th node） period, the sugar content in the upper, middle, and lower segments had increased by 0.96, 1.04, and 0.93 percentage points, respectively, compared to the control.
