摘 要:苗木施肥是培育壮苗的一项主要技术措施,合理施肥能使苗木体内营养元素保持适当的比例,实现苗木稳产、高产。采用田闰试验的方法,以油松3年生换床苗为试材,就不同肥料配比对油松各个营养阶段苗木生长发育的影响进行了研究。探讨了不同施肥配方对油松苗高、地茎、生物量、纤维素的影响。以期为油松营养生理体系的建立及合理化配方施肥提供科学依据。研究结果表明:施肥影响油松幼苗的株高、地径生长及树体的生物量积累。不同施肥处理相比,配施优于单施,以多元肥处理最优,可显著提高各生长指标。经施肥处理的油松与对照相比,生长期内苗高生长量增加10.51%~17.12%,地径生长量增加7.46%~14.93%,生物量增加16.16%~27.29%。Fertilization is a main measure for cultivating strong seedling. Reasonable fertilization can improve the quality and quantity of seedling. In this paper, with the 3 old years Pinus tabulaeformis, we studied the effect of different fertilizer application on plant's height, ground diameter, hiomass and cellulose content for offering the scientific foundation for applying fertilizer rationally in Pinus tabulaeformis. The results showed that application of different fertilizers significantly increased the height, diameter, and biomass accumulation. Compared with the treatments with different fertilizers, compound fertilizer increased the growth targets much significantly than their single application. Compared to the control, the application of fertilizers remarkably enhanced each growth target during the whole growth stages: the height of Pinustabulaeformis was increased by 10.51%- 17. 12%. the diameter by 7.46%- 14.93%, and the blomass growth quantity by 16.16%-27.29%.
