【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的比例。更多还原

【Abstract】 The effects of water stress and water stress combined with fertilization on cotton growth and its yield components were studied in this paper.The results showed that controlling water condition at seedling stage could efficiently depress the growth of cotton stem stature and thus enhance the yield and quality.Under the same fertilization conditions,controlling water condition in prophase could enhance the ratio of reproductive organs to dry weight of whole plants,especially increase the quantity of reproductive organs in prophase and metaphase,and increase the cotton boll setting ratio.更多还原
