摘要
[目的]研究不同施肥处理对扦插苗生长的影响,为提高干旱区扦插苗的质量和加快苗木的培养提供参考。[方法]用完全随机设计方法对林区076-28杂交杨进行了复合肥5种不同施肥量的施肥试验。[结果]不同施肥量处理对076-28杂交杨1、2年生扦插苗的苗高和地径生长有显著的影响。在100g/株的施肥处理时,对苗木生长的影响最大,1、2年生扦插苗的苗高生长都达到最大值,与对照相比都达到极显著差异。[结论]复合肥对1、2年生扦插苗苗高生长都有显著影响,仅对2年生扦插苗地径生长影响显著。
[Objective]The reference for the improvement of the quality and rapid growth of poplar seedling cutting in arid area was provided through the study on the effect of the different fertilization treatments on the seedling cutting.[Method]The experiment in five kinds of different fertilizer compound fertilizers treating hybrid poplar clone 076-28 was conducted with the completely random design method.[Results] There was a significant effect of the different fertilizer treatments on the plant height and diameter growth of 1 and 2 year-old 076-28 poplar seedling-cutting.The greatest impact on seedling growth appeared in the treatment of 100 g fertilizer/plant and the seedling height of 1 and 2year-old cutting reached the maximum,which was a very significant difference with the CK plant.[Conclusion]There was a very significant effect of compound fertilizer on the height of 1 and 2 year-old poplar cutting and on the diameter 2 year-old of poplar cuttings only.
