| 摘 要： | 研究了水分胁迫以及水分胁迫和施肥互作对棉花生长、产量构成特征的影响。结果表明,棉花苗期采用控制水分方法能有效控制主茎生长速度,起到降低棉株主茎高度,培育壮苗的作用;同样施肥条件下,前期适当控制水分,可提高生殖器官与整株干重之比,特别是能增加前期和中期生殖器官量,有利于提高棉花优质铃比例。 |
| 关 键 词： | 棉花 水分胁迫 施肥 优质铃率 |

| Abstract: | This article has studied under water stress and water stress cross fertilize the conditions of cotton growth and its yield components.The results showed that under water stress in their early development stages cotton stem stature is depressed efficiently,its yield and quality is enhanced.Under the same fertilization conditions,control water conditions in prophase it will enhance ratio of reproductive organs to dry weight of whole plant.Especially it will increase the quantity of reproductive organs in prophase and metaphase. |
| Keywords: | Cotton Water stress Fertilize Bolls ratio of quality |
