摘要/Abstract

摘要： 在温室内用砂培的方法研究了NO₃^--N、NH₄⁺-N及其不同配比对水曲柳(Fraxinus mandshurica)幼苗生长的影响.结果表明,水曲柳幼苗在营养液NO₃^--N◇NH₄⁺-N为75◇25时生长最好,营养液中NH₄⁺-N比例继续增加则生长下降.过量的NH₄⁺-N可抑制水曲柳幼苗根系生长,降低幼苗的地下/地上比.营养液中NH₄⁺-N比例增加,水曲柳幼苗的净光合速率下降,体内P浓度增高,而Zn和Fe浓度下降.N素形态明显影响基质的pH值,NO₃^--N比例增加使基质pH值升高,NH₄⁺-N比例增加则基质pH值下降.完全供给NO₃^--N时基质pH值升至7.22,而完全供给NH₄⁺-N时基质的pH值降至4.20.

Abstract: The effect of NO₃^--N and NH₄⁺-N and their different supply ratios on the growth of Fraxinus mandshurica seedlings was studied by sand culture in greenhouse.The highest seedling growth was obtained at a NH₃^--N/NH₄⁺-N ratio of 75/25 in nutrient solution.The growth of seedlings declined with the increasing ratio of NH₄⁺-N to NO₃^--N. Excessive NH₄⁺-N inhibited root growth,and the root/shoot ratio of the seedlings significantly decreased as the NH₄⁺-N/NO₃^--N ratio was over 50%.Increasing NH₄⁺-N in nutrient solution led to the decrease of net photosynthetic rate,the increase of phosphorus content in plant tissues,and the decrease of Zn and Fe contents.The pH value of cultural medium was affected markedly by nitrogen form,which was increased with increasing NO₃^--N and decreased with increasing NH₄⁺-N in nutrient solution.The pH value was up to 7.22 in the medium contained NO₃^--N alone,while decreased tO₄.20 only with NH₄⁺-N.
