摘　　要：对1991、1992和1997年安阳市二个主栽棉花品种分析表明,厄尔尼诺现象发展阶段,气温偏高、干旱,有利棉铃发育,霜前皮棉较常年增产25.0％以上,其中中棉所12增幅大于中棉所16;而1992年暖冬、干旱,棉铃虫大发生,棉花生长季又处于该现象衰减阶段,气温下降过早过快,影响棉铃成长,夏棉霜前皮棉较常年减产36.1％,春棉只有常年40.0％左右,纤维品质下降,2.5％跨长缩短了2mm。Analyses on two major commercial varieties in 1991 , 1992 and 1997 in Anyang , showed that in the advancing stage of ENSO, the hot - dry weather favoured the development of boll, the lint yields before frost increased over 25% than that of normal years, and the yield increases of CRI 12 were greater than those of CRI 16. However, by warm- winter and arid in 1992, the cotton boll - worm harmed seriously, and it was the declining stage of ENSO during cotton growth period, the air temperature fell too fast and early, that affected the growth of boll. The yield of summer cotton was decreased by 36.1 % , and there was only 40. 0% of the yield of normal years on spring cotton, 2.5% span length shortened 2mm, fiber quality grade descended .
