| 摘 要： | 研究了褐土区不同施磷量对烤烟体内氮、磷、钾含量、积累和分配的影响。结果表明 ,在烤烟生长发育过程中 ,增施磷肥增加了根、茎、叶中磷、钾的含量 ,降低了根和叶中氮的含量 ;同时 ,增施磷肥还增加了根、茎、叶中氮、磷、钾的积累量 ;各生育时期不同处理根、茎、叶中氮、磷、钾含量和积累量的变化规律一致。另外 ,增施磷肥不影响氮、磷、钾在根、茎、叶中的绝对分布量 ,但随磷肥用量增加 ,根中磷的相对分布量增大

| Abstract: | Studies with different phosphorus rate on cinnamon soil in 2001-2002.Demonstrated that with the rate of phosphorus fertilizer increasing,the content of phosphorus and potassium in roots, stems and leaves increased while the content of nitrogen in roots and leaves decreased.The accumulation amounts of nitrogen, phosphorus and potassium in the roots, stems and leaves increased when phosphorus fertilizer increased.The content and accumulation of nitrogen,phosphorus and potassium in root stem leaf during different growth stages manifested same change trend.While phosphorus rate increased, the relative distribution of phosphorus in root increased but it doesn't influenced the absolute distribution of nitrogen, phosphorus and potassium in the root, stem and leaves. |
