摘 要
本研究旨在探讨不同灌溉方式对棉花生长的影响。通过对比滴灌、喷灌和漫灌三种灌溉方法，分析其对棉花生长发育及产量的作用。实验在相同土壤和气候条件下进行，确保了数据的可比性。研究采用随机区组设计，每种灌溉方式设置三个重复，以消除偶然误差。通过定期观测棉花的生长情况，记录株高、叶面积、生物量等生理指标，并在收获后统计棉花产量。结果表明，滴灌方式下棉花生长最为健壮，产量也显著高于其他两种灌溉方式。喷灌方式下棉花生长情况次之，而漫灌方式则相对较差。本研究创新性地结合了生理指标与产量数据进行综合分析，揭示了不同灌溉方式对棉花生长的细致影响。

EFFECTS OF DIFFERENT IRRIGATION METHODS ON COTTON GROWTH
ABSTRACT
The purpose of this study was to investigate the effects of different irrigation methods on cotton growth. The effects of drip irrigation, spray irrigation and flood irrigation on cotton growth and yield were analyzed by comparing the three irrigation methods. The experiments were conducted under the same soil and climate conditions, ensuring the comparability of the data. The study adopted a random block design with three replicates for each irrigation method to eliminate accidental errors. Through regular observation of cotton growth, plant height, leaf area, biomass and other physiological indicators were recorded, and cotton yield was counted after harvest. The results showed that the growth of cotton under drip irrigation was the most robust, and the yield was significantly higher than the other two irrigation methods. The growth of cotton under sprinkler irrigation was the second, while that under flood irrigation was relatively poor. This study innovatively combined physiological indexes and yield data for comprehensive analysis, revealing the subtle effects of different irrigation methods on cotton growth.
