摘要:
 为研究不同施肥方法对欧洲云杉（Picea abies）无性系生长生理特性和根系形态的影响。2012年3-8月，在甘肃省天水市小陇山林业科学研究所，以2年生欧洲云杉无性系pab08ts0263组培苗为试材，通过盆栽试验对不同施肥方法下植株根系生长发育各项指标进行测定分析。结果表明，不同施肥方法（等量施肥、指数施肥和反指数施肥）均有效促进欧洲云杉无性系生长、生物量分配、叶绿素含量、光合特性和根系特征值，但不同施肥方法下其效应有所差异。指数施肥剂量对欧洲云杉根系生长发育的促进效果最明显（p<0.05），其处理植株根系形态指标均是对照的1.7倍以上（1.73 ~3.83倍），而根系生物量、根冠比、叶绿素含量、净光合速率、蒸腾速率、水分利用效率和气孔导度也显著高于对照；此外，根、茎、叶的含N量分别是对照的1.29倍、1.60倍和1.46倍。可见，3种施肥方法均能有效促进欧洲云杉无性系的生长，其中指数施肥的效果最佳。
Abstract:
 In order to study the responses of different fertilizing methods on the growth, physiological characteristics and root morphological traits of Picea abies clone, we conducted the experiment in Xiaolongshan Forestry Science and Technology Research Institute, from March to August of 2012. A set of growth and development traits of two-year P. abies roots(clone pab08ts0263) were evaluated in pots under different fertilization methods. The obtained results indicated that different fertilization methods (the same amount of fertilizer/D, index fertilization/Z and anti index fertilization/F) all had positive effects on the growth and development of the growth, biomass allocation, chlorophyll content, photosynthetic characters and root characteristic values, while the degrees of the effects were different. The positive effect of index fertilization appeared to be the most impressive, a significant change of roots morphology over 1.7 times(1.73-3.83 fold) to the control, and the biomass of roots, root to shoot ratio, chlorophyll content, net photosynthetic rate, water use efficiency and stomatal conductance were higher than those of the control at a significant level; moreover, the nitrogen content of roots, stems, leaves were 1.29, 1.60 and 1.46 times to the control. Three fertilization methods all had a positive effect on the growth of P. abies clone and the index fertilization was the best.
