| 摘 要： | 对两个不同生态类型的棉花高产品种，从开花前至盛铃期以前，模拟生产中常出现的四种棉田供水情况，研究表明：花铃期适水供应处理棉田，叶面积指数增长快、群体干物质积累速率高、产量高，主要原因在于棉花群体光合速率高，呼吸虽高，但呼吸所占比例较低所致。后旱处理对棉花的产量影响不明显，但可大大提高水分利用率。中后旱处理对棉花产量及水分利用效率影响最大；新陆早７号忍耐中后期干旱较弱于新陆早６号。 |

| Abstract: | Two varieties of differdent ecological types were studied under conditions with four treatments of soil water contents during blooming period.The results indicated that,the increasing of LAI,accumulation of dry matter ,with suitable supply of water were higher than that of early,middle later drought The respiration of suitable supply water treatment was also higher,but the CP/CAP was lower,the effect of the later drought treatment on yield was unnotable,but on improving WUE was notable, the yield,WUE,accumulation of dry matter of middle later drought treatment was the lowest The tolerance of Xinluzao No 7 to drought was weaker than that of Xinluzao No 6 |
| Keywords: | cotton soil water content physilolgical characteristic effect yield |
