| 摘 要： | 在试验基础上 ,分析讨论了温室滴灌条件下铵态氮的转化迁移规律。研究表明滴灌条件下铵态氮主要在扩散机理作用下迁移速度缓慢 ,迁移距离小 ,在近离滴头附近的表层土壤中显著聚集。就吸附作用和硝化作用对铵态氮转化迁移规律的影响作了定量讨论。

| Abstract: | An experiment was carried out to investigate NH 4 +N transformation and transport under drip irrigation in greenhouse. Results indicate that the transformation and transport of NH 4 +N are driven mainly by diffusion effects. The transport process was conducted with low speed and within a small range in the soil under drip irrigation, and the NH 4 +N accumulation occurred mainly in a small size under the emitter. In addition, the effects of sorption and nitrification on NH 4 +N transformation and transport also were analyzed quantitatively in this paper. |
