中文摘要:
      为了研究不同铵态氮和硝态氮比例对独本菊黄河生长发育和养分吸收的影响,试验在总氮浓度一定的情况下。设定NH4+—N:NO3-—N 分别为2:1、1:1、1:2 3个处理。通过对植株株高、叶片数、叶绿素含量、花期、花径、管瓣数、茎粗、节间长、叶长、叶宽、元素含量的数据分析,结果表明:当NH4+-N:NO3--N 为2:1 时株高和叶片数最大,花径最大,花期较长,茎粗最粗,叶长和叶宽也最大。不同铵态氮和硝态氮比例对黄河对氮、磷、钾、钙、镁的吸收无显著影响。
英文摘要:
      In order to study the effects of different ratios of ammonium nitrogen and nitrate nitrogen on the growth and nutrient absorption of standard chrysanthemum ‘Huanghe’, ammonium nitrogen and nitrate nitrogen ratios were set as 2:1, 1:1, 1:2, while total nitrogen concentration was 200 mg/L. By analyzing plant height, leaf number, chlorophyll content, florescence, flower diameter, tubular petal, stem diameter, internode length, leaf length, leaf width and element content, when NH4+-N:NO3--N=2:1, most indicators reached the maximum. Different ammonium nitrogen and nitrate nitrogen ratio had no significant influence on nutrient absorption.
