| 摘 要： | 2006-2008年,运用3种试验处理方法对运城市棉花需水规律进行了研究.结果表明:全生育期棉花的需水量为504.1 ～564.8mm；开花-吐絮期需水量最大,占全生育期需水量的37.80％ ～43.95％,其次为现蕾-开花期；2006年和2008年需水强度最大的阶段是现蕾-开花期,分别为5.36、5.51 mm/d,其次为开花-吐絮期；2007年需水强度最大的是开花-吐絮期,为5.47 mm/d,其次为现蕾-开花期.从棉花的整个生育期来看,土壤供水所占比例较小,甚至出现负值,但是从个别生育阶段来看,土壤供水是棉花耗水的主要来源.正常年份灌溉对棉花生长具有明显的增产作用,增产率为13.82％～36.30％.

| Abstract: | Water requirement law of cotton was studied in Yuncheng from 2006 to 2008 by three different testing treatment methods.The result indicates that: Cotton water requirement of whole growth stage is 504.1-564.8 mm.The period from flowering to boll opening has the maximum water requirement,37.80%-43.93% of whole growth stage's,followed by the period from squaring to flowering.The period from squaring to flowering had the maximum water requirement intensity which is 5.36 mm/d and 5.51 mm/d in 2006 and 2008,follo... |
