摘要：

为明确鲁西南地区蒜后直播棉适宜的缩节胺化控方案，以短季棉品种‘鲁棉551’为试材，采用单因素随机区组设计，设置3个处理，分别在现蕾期、初花期、盛花期和打顶7日后喷施缩节胺，喷施剂量(T1：0 g/hm2、0 g/hm2、75.0 g/hm2、105.0 g/hm2；T2：0 g/hm2、45.0 g/hm2、60.0 g/hm2、75.0 g/hm2；T3：15.0 g/hm2、30.0 g/hm2、60.0 g/hm2、75.0 g/hm2)，清水为对照(CK)，系统研究不同施用时期和用量对棉花农艺性状、干物质积累、产量及纤维品质的影响。结果表明：全生育期缩节胺总用量不变的前提下，随着缩节胺喷施时间分次前移能够显著抑制棉花株高，提高单株结铃数和单铃重，从而达到增产的效果，其中T3皮棉产量分别比T2、T1、CK增加3.8%、12.5%、30.8%，不同处理的产量表现为T3>T2>T1>CK，同时也能增加根系和蕾铃的干物质重，降低赘芽的干物质重，但对棉花纤维品质无显著影响。试验中T3处理的产量及农艺性状较优，综上，鲁西南地区蒜后直播棉采用“前轻后重、少量多次”的缩节胺化控策略，即现蕾期15.0 g/hm2、初花期30.0 g/hm2、盛花期60.0 g/hm2和打顶7日后75.0 g/hm2，可实现株型优化、干物质合理分配与产量提升，为当地短季棉优质高效生产提供技术支撑。

Abstract:

To investigate the effects of DPC on agronomic traits, dry matter accumulation, yield, and fiber quality of direct-seeded cotton following garlic in southwest Shandong, and to determine the appropriate growth regulator timing and dosage, a field experiment with single factor randomized block design was conducted in 2024 using the short-season cotton variety ‘Lumian 551’. Three treatments were designed and DPC was applied at the squaring, initial flowering, full flowering, and 7 days after topping stages, respectively. The spraying dosages were T1: 0, 0, 75.0, 105.0 g/hm2; T2: 0, 45.0, 60.0, 75.0 g/hm2; T3: 15.0, 30.0, 60.0, 75.0 g/hm2, with water serving as the control (CK). Results showed that, under an equal total DPC dosage across the growth period, earlier and more frequent DPC applications significantly reduced plant height, increased boll number per plant and single boll weight, and ultimately improved lint yield. The lint yield followed the order T3>T2> T1 > CK, with T3 increasing yield by 3.8%, 12.5%, and 30.8% compared with T2, T1, and CK, respectively. DPC application also enhanced dry matter accumulation in roots and fruiting branches, while reducing that in vegetative branches. However, no significant differences were observed in fiber quality among treatments. Overall, the T3 treatment (15.0 g/hm2 at squaring, 30.0 g/hm2 at initial flowering, 60.0 g/hm2 at full flowering, and 75.0 g/hm2 7 days after topping) exhibited the best yield and agronomic performance, suggesting it as the optimal DPC application strategy for direct-seeded cotton after garlic in southwest Shandong.
