| 中文摘要: |
| 以新陆早48 号为材料，开展土优塔棉花打顶剂的田间比较试验，研究化学打顶对棉花农艺性状、
品质、产量等的影响，结果表明，经不同用量土优塔棉花打顶剂处理后，棉花的株高、果枝台数、叶龄数等农
艺性状均优于人工打顶（CK），打净率在80% 以上。化学打顶不同用量处理棉花的单铃重增大，皮棉重、霜前
花率与对照无明显差异，喷施600、750、900 mL/hm2 用量土优塔棉花打顶剂相对于对照具有增产效果。化学打
顶不同处理的百粒重、籽指、衣指、纤维长度、马克隆值、整齐度、伸长率等与对照相比均无显著差异。说明土
优塔棉花打顶剂能有效控制株高，但对棉花的产量和品质影响不大。 |

| Abstract：With Xinluzao 48 as materials，field comparison test of soil tower cotton topping agent was carried out
to study the effects of chemical topping agent on agronomic traits，yield，quality of cotton，to provide a scientific basis
for the popularization and application of chemical topping technology for cotton. Results showed that，in different dosage
of soil tower cotton topping treatment，the plant height，branch number，leaf number were better than those of artificial
topping（CK），and the net rate of topping was more than 80%；The single boll weight increased，ginned cotton weight
and pre frost flower rate had no significant difference with the control（CK），praying 600，750，900 mL/hm2 soil tower
cotton topping agent had yield-increasing effect；100-seed weight，seed index，lint index，fiber length，micronaire
value，uniformity and elongation had no significant difference with the control. The result indicates that tower soil cotton
topping agent can effectively control the plant height，but has no obvious effect on the yield and quality of cotton. |
