| 摘 要： | 棉花是耐盐作物,但土壤耕层中积累过多的盐离子会通过离子毒害、渗透胁迫和引起营养失衡等机制导致盐害。控制棉花盐害的途径主要有两条,一是提高棉花自身的耐盐性,另一方面是躲避或减轻盐胁迫。本文评述了提高棉花耐盐性和躲避或减轻盐胁迫的途径、原理和方法,提出在工程措施改良盐碱地的基础上,综合运用适宜品种、水肥运筹、种子处理及地膜覆盖和诱导根区盐分差异分布等农艺措施是现阶段控制盐碱地棉花盐害的有效途径。 |

| Abstract: | Two effective measures can be taken for salinity injury control to cotton (Gossypium hirsutum L.). One is to improve salinity tolerance of cotton plants, and the other is to avoid or alleviate salt stress. The methods and principles of improving salt tolerance and of avoiding or alleviating salt stress were commented. It is suggested that, besides saline soil improvement with engineering measures, comprehensive utilization of agronomic measures such as suitable cultivars, irrigation and fertilization, seed treatment, furrow seeding with plastic mulching，and induction of unequal salt distribution in the root-zone were effective to control salt-injury in cotton. |
