不同回填土与施肥条件对滇朴移植生长的影响研究

Effects of Different Backfill Soils and Fertilization Conditions on the Growth of Celtis kunmingensis

以云南乡土树种滇朴为试验材料,以原壤、黄壤、棕壤三种土壤为移植回填土,施加不同剂量复合肥,1年后调查滇朴树苗移植成活率和生长高度。研究结果表明,回填土类型对于滇朴成活及生长情况有显著影响,树苗在酸性棕壤上长势最好,其次为微酸性黄壤,再次为中性原壤;施肥量与滇朴树苗成活率关系不大,但对其生长情况有显著影响,单株最佳施肥量为300~600 g。

Using Yunnan native tree species Celtis kunmingensis as the experimental material, using theoriginal soil, yellow soil and brown soil as the backfill soil, different doses of compound fertilizer wereapplied to investigate the survival rate and growth height of the seedlings.The results showed that threebackfill soils had a significant effect on the survival and growth of Celtis kunmingensis, the saplings grewbest in acidic brown soil, followed by slightly acidic yellow soil, and then neutral soil, and the fertilizationamount had little relationship with the survival rate of Celtis kunmingensis sapling. But it had a significanteffect on the growth of saplings, and the optimum fertilization rate per plant was 300~ 600 g.
