摘要
研究了在盆栽和田间小区试验条件下,叶面和土壤施用铁肥以及土施酸化肥料对纠正花生缺铁黄化症的作用效果。在盆栽条件下,叶面喷施黄腐酸铁(FeFA)、土施硫酸亚铁及酸化肥料都可以提高花生新叶中活性铁以及叶绿素含量,促进花生植株的生长;在田间小区栽培条件下,叶面喷施FeFA可以提高花生的叶绿素含量,尿素与FeFA结合使用的作用效果大于单喷FeFA。土施硫酸亚铁在花生生长前期提高了花生叶绿素含量,后期作用不明显。叶面喷施与土施铁肥都可以增加花生产量,土施铁肥的作用效果不如叶面喷施效果明显,酸化肥料对提高花生叶绿素含量及产量没有明显效果。
Effect of different methods of Fe-fertilizer and acid fertilizer application on the iron chlorosis correction of peanut is studied. The results show that different methods of Fe-fertilizer and acid fertilizer application can improve active iron and chlorophyll content in peanut fresh leaves in pot. Supplying fertilizer can also improve plant growth of peanut in pot; On plot experiment, spraying FeFA can improve chlorophyll content in peanut fresh leaves. Effect of mixture of urea and FeFA is better than FeFA. Supplying Fe-fertilizer can improve chlorophyll content in the fresh leaves of peanut on early period. The application of Fe-fertilizer can improve the yields of peanut. Effect of supplying acid fertilizer isn' t obvious.
