摘要
以棉花(Gossypium hirsutum L.)品种聊棉6号为材料,研究了不同打顶时间及剂量对棉花株型性状、新生节间、果枝长度、产量性状及纤维品质的影响。结果表明,与人工打顶同期喷施该化学打顶剂1 125m L/hm2能够改变棉花株型性状,改善棉田上部群体结构,在搭成丰产架子的同时能有效改善棉田通风透光性,在一定程度上可提高棉铃数目、单铃重及产量,但对棉花纤维品质无明显影响。
We studied the effects of different detopping time and dose on plant type,length of new internodes and branches,yield and fiber quality of Liaomian 6. Results indicated that 1 125 mL/hm^2 was the proper dose which could change plant type,improve upper population structure,improve ventilation and light transmission,and increase the boll number,boll weight and yield. However it had no significant influence on fiber quality.
