苧麻不同生长期的机械物理性能及生物学特性的研究

A Study of Mechano-physical Properties and Biological Characteristics of Ramie for Different Planting Periods

本文以动态观点研究各季苧麻纤维的机械物理性能及生物学特性与生长期关系的变化规律。大量数据证明,按传统的农作制度,我国苧麻生长期过长,致使苧麻纤维粗壮,品质低下,有的甚至超过1特。因此,将每年收三季苧麻改为收四季苧麻,即可提高优质苧麻纤维在原麻中的构成比例,取得明显的经济效益及社会效益。

The paper reports the study on the variation way of the relationship between mechano-phy-sical properties as well as biological characteristics and planting periods of ramie. A lot ofdata indicate that according to the Chinese farming system the domestic ramie grows generallytoo long time to become coarse fibre even more than 1 rex with poor quality.Therefore,if thecropping times in one year are changed from 3 into 4 for ramie growth,this can raise the con-tent of premium ramie fibre in raw ramie to get a certain economical result.
