| 摘 要： | 本文研究了暗棕壤条件下氮、磷施肥对长白落叶松播种苗质量的影响.结果表明:氮磷肥施用比例显著影响长白落叶松播种苗苗高、地径和主根生长；过量供氮并没有造成苗木徒长,而是通过加剧氮磷供应的不平衡来限制养分的均衡吸收,抑制苗木生长；在本试验地土壤有效氮富集而有效磷缺乏的条件下,长白落叶松播种苗适宜的施肥管理措施是控制肥料施入,... |

| Abstract: | This experiment was conducted to assess the effects of nitrogen(N) and phosphorus(P) fertilizers on Larix olgensis seedling quality in dark brown soil and the results demonstrated that: applying proportion of N and P could significantly affect the height,diameter and length of taproot in treatments.Excessive supplying of N did not make the seedling excessively grow,but repressed seedling growth through exacerbating supplying balance of N and P and limiting balanced absorption of nutrients.In this site that ... |
| Keywords: | Larix olgensis proportion of nitrogen and phosphorus fertilization seedling quality |
