中文摘要:
      对新疆北疆苗期遭受不同程度冻害的棉花生长进行了全生育期跟踪调查,结果表明棉花苗期冻伤程度不同,对产量及生育期进程的影响也不同。当冻伤程度为10%时,棉花可以通过后期空间优势,使最终产量得到补偿,因此对产量的影响不大;当冻伤程度达到15%时,棉花的生育期延迟,棉花的产量明显低于对照。
英文摘要:
      Cotton suffering from different frostbites was closely studied in North Xinjiang Uigur Autonomous Region, Which concluded that different frostbites occurring at seedling stage showed different effects on cotton yields and growth. Where the frostbite severities reached 10%, cotton made full use of advantageous spaces at its late growth resulting from the frostbites taking place at its seedling stage to compensate its yield, Where the frostbites reached 15%, the stages of cotton growth were delayed so that cotton yield was remarkably lowered.
