棉蚜对棉纤维物理性状含糖量及棉结量的影响

A Study on the Inffuence of A phis Gossypii Glover on the Physical Characters, Sugar Contents of the Cotton Fibre and the Quantity of the Flaws on Cloth

研究结果表明，棉蚜与棉纤维主要物理性状、含糖量和棉结量有关．无蚜害棉、伏蚜为害棉和伏、秋蚜为各且蜜露污染棉除在长度性状上差异不大外，三者在细度、单强、成熟度等主货物理性状、含糖量和试纺棉布的棉结量上有明显的差异。

The results showed that the damage by Aphis gossypii Glover with the main physical characters,sugar contents of the cotton fibre and the quantity of the flaws on cloth.The differences were not significent in the fibre length,but were significent in fineness,individual strength,maturity,sugar contents of cotton fibre and quantity of the flaws on cotton cloth,among the cotton non-damaged,damaged by aphids in summer and damaged by aphids both in summer and autumn.
