摘　　要：以杂交棉“瑞杂818”为材料,于2021—2022年在菏泽市农业科学院试验基地进行蒜套棉试验,研究不同拔柴时间(9月20日、9月25日、9月30日、10月5日和10月10日)对棉株不同部位铃的产量和品质的影响。结果表明:拔柴时间对棉株中下部铃重、衣分和籽棉产量影响不明显,而对上部铃影响较大,且拔柴时间越早影响越大。棉纤维上半部平均长度、断裂比强度和马克隆值随着拔柴时间的提前而降低,拔柴时间越早降低幅度越大。拔柴时间对棉株下部铃纤维上半部平均长度、断裂比强度和马克隆值影响不明显,而对中上部铃影响较大,相比10月10日拔柴,9月20日拔柴纤维上半部平均长度、断裂比强度和马克隆值分别降低11.91%、9.99%和14.29%。Hybrid cotton“Ruiza 818”was used as material,the experiment of garlic interplanting cotton was carried out in the experimental base of Heze Academy of Agricultural Sciences from 2021 to 2022,the effects of different stalk pulling time(September 20,September 25,September 30,October 5 and October 10)on the yield and quality of bolls in different parts of cotton plants were studied.The results showed that the effect of stalk pulling time on boll weight,lint percentage and seed cotton yield in the middle and lower parts of cotton plant was not obvious,while the earlier the stalk pulling time,the greater the effect on the upper boll of cotton plant.The average length,breaking strength and micronaire value of the upper half of cotton fiber decreased with the advance of stalk pulling time,and the earlier the stalk pulling time,the greater the decrease.The effect of stalk pulling time on the average length,breaking strength and micronaire value of the upper half of boll fiber in the lower part of cotton plant was not obvious,but it had a great influence on the middle and upper bolls,the average fiber length,breaking strength and micronaire of the upper part of the cotton plant on September 20 were 11.91%,9.99%and 14.29%lower than those on October 10,respectively.
