Drought can significantly impact fiber crop cultivation due to the plants' specific water requirements and their extended vegetative period. The purpose of the research was to examine how drought stress affects the quality and chemical composition of hemp ( L.) fibers. A three-year pot experiment was conducted in a plant growth facility, using controlled drought stress for hemp plants. Soil moisture levels were maintained at three levels, where 45% field water capacity was the control and 35% and 25% FWC were drought. A comprehensive suite of fiber quality characterization techniques, including linear density measurement, tenacity assessment, Fourier Transform Infrared Spectroscopy (FTIR), and Wide-Angle X-ray Diffraction (WAXD), was employed to evaluate the impact of drought stress on fiber properties. The chemical composition of hemp fibers was thoroughly analyzed, quantifying the content of cellulose, hemicellulose, pectin, and lignin. The findings indicate that drought conditions significantly influence linear density, wax and fat content, as well as the crystallinity of the fibers.
由于纤维作物对水分有特定需求且营养生长期较长，干旱会对其种植产生重大影响。本研究的目的是考察干旱胁迫如何影响大麻（L.）纤维的质量和化学成分。在植物生长设施中进行了为期三年的盆栽试验，对大麻植株施加可控的干旱胁迫。土壤湿度维持在三个水平，其中45%的田间持水量为对照，35%和25%的田间持水量为干旱处理。采用了一套全面的纤维质量表征技术，包括线密度测量、强度评估、傅里叶变换红外光谱（FTIR）和广角X射线衍射（WAXD），以评估干旱胁迫对纤维性能的影响。对大麻纤维的化学成分进行了深入分析，量化了纤维素、半纤维素、果胶和木质素的含量。研究结果表明，干旱条件会显著影响线密度、蜡质和脂肪含量以及纤维的结晶度。
