| 摘 要： | 为优化甘蔗高产高效栽培技术,以桂糖49号为试验材料,研究了促根剂处理甘蔗单芽种茎对其农艺性状、生理生化指标、品质及产量的影响。结果表明,与不包衣（CK2）相比,包衣+50mg/L促根剂（T1）、包衣+100mg/L促根剂（T2）和包衣（CK1）的甘蔗出苗率、分蘖率、株高和有效茎数显著提高,产量分别增加27.5%、9.2%和8.2%,产糖量分别增加27.4%、9.2%和8.3%;同时,促根剂可提高甘蔗生长速度,提高甘蔗叶片可溶性蛋白、可溶性糖和脯氨酸含量,对甘蔗品质略有提升,但不显著。因此,促根剂能有效促进甘蔗生长,提高甘蔗产量和产糖量,促根剂浓度100mg/L的效果最佳。

| Abstract: | In order to innovate and to optimize the high-yield and high-efficiency cultivation technology of sugarcane, the effects of root promoting agents on agronomic characters, physiological and biochemical indexes, quality and yield of sugarcane were studied. The results showed that coating+50mg/L root promoting agent (T1), coating+100mg/L root promoting agent (T2) and coating (CK1) significantly increased the germination rate, tillering rate, plant height and number of millable stalks, by compared with not coating (CK2). The sugarcane yield of T1, T2 and CK1 were significant higher than CK2 by 27.5%, 9.2% and 8.2% respectively, and the sugar yield per hectare were higher than CK2 by 27.4%, 9.2% and 8.3%, respectively. At the same time, root promoting agents had certain effect on the growth rate of sugarcane. The content of soluble protein, soluble sugar and proline in sugarcane were improved, and there was no significant difference among the treatments. The results showed that the root promoting agents had positive effect on the growth of sugarcane, the yield and sugar yield of sugarcane with 100mg/L of the best concentration. |
