- 摘要:
- 为了解污泥施肥于红壤中，P在剖面中的淋溶和迁移状况，通过田间试验分别对污泥不同类型、施用量和施肥方式在典型红壤坡地P垂直迁移状况进行研究。结果表明：（1）不同处理的污泥施用均可引起Kcl-P和Olsen-P在红砂壤上的垂直迁移，含量随剖面深度而降低，养分积累主要集中在0—50 cm土层；（2）污泥类型、施肥量、施用方式都对P素迁移具有影响，随着施肥量的增加，剖面各层Kcl-P和Olsen-P含量增加，撒施处理比穴施更易造成Kcl-P和Olsen-P剖面深层迁移，干污泥养分含量随剖面深度变化更剧烈，更易造成Kcl-P深层迁移；（3）污泥撒施0—30 cm土层Olsen-P累计量占0—80 cm总累计量60%以上，基本可以反映剖面Olsen-P含量水平和迁移潜力。
- Abstract:
- Leaching of phosphorus (P) from soils is the potential environmental hazard. Understanding transfer characteristic of P in the red sandy soils is important to sewage agricultural utilization. In this paper, sewage was used by the ways of broadcast and hole application with different types and application amounts in the field,and the phosphorus transfer characteristic was investigated on the 225th day after sewage application. The results showed that (1) the Kcl-P and Olsen-P accumulated in the whole profile, and the phosphorus concentration decreased with the increase of soil depth both in broadcast and hole application; (2) the phosphorus transfer was affected by the sewage application amounts and application methods, the concentrations of Kcl-P and Olsen-P in the profile increase with the increase of application amounts, and the phosphorus accumulated in deeper soil after broadcast application than the hole treatments; (3) Olsen-P accumulating between 0-30 cm accounted for over 60% of the whole profile after broadcast application.
