摘要
[目的]研究磷肥对核桃楸苗木质量的影响,为核桃楸优质壮苗的培育提供技术支撑。[方法]通过不同磷肥水平(0,10,20,30g/m)的试验,确定磷肥合理施用量。[结果]施用磷肥可明显地促进核桃楸苗木的高生长、地径生长、根系生长和生物量积累,各施肥水平间差异显著,以施肥量10 g/m处理的苗高较高、茎干粗壮、根系发达、生物量高,苗木质量最优。[结论]为培育大量优质壮苗,应合理施用磷肥。
[ Objective ] This paper studied the effect of phosphatic fertilizer on seedling quality of Juglans mandshurica. [ Method ] Through the experiment of different fertilizer levels to determine the reasonable applying phosphorus content. [ Result] The research results showed that phos- phatic fertilizer could significantly promote the seedling height growth, diameter growth, root growth and biomass accumulation. The difference were significantly between the levels of fertilization. When the amount of fertilizer was 10 g/m, seedling height was higher, stem was thicker, root system was more developed, biomass was higher, and seedling quality was the best. [ Conclusion] To cultivate a large number of high quality seedling, we should make good use of phosphate fertilizer.
