摘要: 【目的】研究6-苄氨基嘌呤(6-BA)对棉花现蕾成铃和产量的影响,筛选适宜的6-BA喷施浓度,减少蕾铃脱落和增加棉花产量。【方法】以鲁棉研24号为供试材料,2018年在新疆兵团第八师石河子总场四分场三连进行叶面喷施6-BA试验,设置 0(CK)、20 mg/L(T1)、30 mg/L(T2)、40 mg/L(T3)四个浓度梯度。【结果】随着6-BA喷施浓度的增加,棉花果枝数和果节量增加,与CK相比,T1、T2、T3处理果节量分别增加了9.8%、13.2%和18.7%,且T2处理显著增加下部果枝外围果节数,上部外围果节数T3极显著高于CK达16.9%;浓度越高现蕾增加越多,而且可以延迟最大现蕾时间;T1、T2、T3分别增加了花后16~26 d、26~36 d、26~36 d的棉花成铃数,均提高了上部果枝内围果节的成铃概率;T2对铃数和铃重分别提高了12.4%和13.7%,籽棉产量增加27.82%。【结论】蕾铃期叶面喷施6-BA可以增加棉花成铃数和铃重,提高籽棉产量。6-BA浓度为30 mg/L时,棉花籽棉产量最高,达5 359.6 kg/hm。

Abstract: 【Objective】 To explore the effects of 6-benzylaminopurine (6-BA) on the bud, boll and yield of cotton, and to select the optimal 6-BA spray concentration to reduce bud and boll shedding and increase cotton yield.【Methods】 Foliar spraying experiment by using different concentrations of 6-BA in Lumianyan 24 was conducted at the Shihezi four-point field. The different concentrations of 6-BA were set as 0 (CK), 20 mg/L (T1), 30 mg/L(T2), 40 mg/L (T3). 【Result】 With the increase of 6-BA spraying concentration, the number of cotton fruit branches and fruit nodules increased. Compared with CK, the fruit weight of T1, T2 and T3 treatment increased by 9.8%, 13.2% and 18.7%, respectively. T2 treatment significantly increased the number of peripheral fruit branches. The outer peripheral branches of T3 were significantly 16.9% higher than those of CK. The higher the concentration, the more the buds increased, and the maximum bud time was delayed. T1, T2 and T3 increased after 16-26 day. The cotton bolls of 26-36 and 36-56 day all increased the probability of boll formation in the surrounding fruit section of the upper fruit branch; T2 increased the number of bolls and boll weight by 12.4% and 13.7%, respectively, and the seed cotton yield increased by 27.82%.【Conclusion】Spraying 6-BA on leaves could increase boll number and boll weight of cotton and increase seed cotton yield during bud and boll stage. When the concentration of 6-BA was 30 mg/L, the seed cotton yield was the highest which reached 5,368.3 kg/hm2. The results are of great significance to guide the high yield cultivation techniques of cotton in Xinjiang
