苧麻(Boehmeria nivea)为多年生宿根草本植物,原产我国,是重要韧皮纤维作物之一。苧麻纤维具有细长、强韧、洁白、易于染色、耐腐和绝缘等特点,是纺织工业、渔網业及其他工业的重要原料。 苧麻产量,决定于单位面积茎数、茎的高度与细度及韧皮纤维发育情况等。研究苧麻纤维发育情况,掌握其规律,以便于采取措施促进麻茎生长并加速纤维发育过程,对争取丰收具有重要意义。 二、材料和方法 本试验探讨纤维层纵向、径向发育,纤维细胞发育和纤维量的累积过程等问题。在华中农学院苧麻品种比较试验地进行。品种 Boehmeria nivea, a perennial perennial herb native to China, is one of the major bast fiber crops. Ramie fiber with slender, tough, white, easy to stain, corrosion and insulation characteristics, is the textile industry, fishing nets and other industries an important raw material. Ramie yield, determined by the number of stems per unit area, stem height and fineness and bast fiber development. Studying the development of ramie fiber and grasping its regularity in order to take measures to promote the growth of hemp stems and accelerate the fiber development process is of great significance for gaining a good harvest. Second, materials and methods This experiment to explore the longitudinal and radial fiber layer development, fiber cell development and accumulation of fiber volume and other issues. In Huazhong Agricultural College ramie varieties to conduct comparative experiments. Variety
