摘要
研究不同施肥处理对核桃楸苗木生长影响的结果表明,氮磷钾组合施肥能显著促进核桃楸苗木的生长,对高径生长、根系发育和生物量均有明显地增效作用。不同施肥处理间在幼苗的苗高、地径、主根长、侧根数和生物量等指标上存在显著性差异。综合影响苗木质量的各项指标,以施氮10 g/m、磷(P_2O_5)6 g/m、钾(K_2O)6 g/m配比的处理表现最优,为适宜的施肥处理,该项研究为核桃楸育苗合理施肥技术提供了依据。
The effect of different fertilization treatment on the growth of Juglans mandshurica seedling was studied. The results showed that the combination of nitrogen,phosphorus and potassium fertilizers could significantly promote the growth of the seedlings. There were obvious synergistic effects on the high diameter growth,root growth and biomass. There was a significant difference in the indexes of the seedling height,diameter,main root length,lateral root number and biomass between different treatments. As for comprehensive effect on seedling quality,in the treatments,the optimal combination was 10 g / m nitrogenous fertilizer,6 g / m phosphate fertilizer（ P_2O_5）,6 g/m potash fertilizer（ K_2O）. The study will provide the basis for seedlings fertilization technology on cultivation of J. mandshurica.
