| 摘 要： | 用不同酸度的模拟酸雨,通过严格的土柱淋洗试验,研究了在不同酸度的模拟降水下,重庆市施用不同肥料的蔬菜地的土壤(紫色土壤)中磷元素(P元素)淋失量的变化情况。结果表明,不同酸度的降雨对土壤磷元素的淋失量的影响不同,总体上酸雨引起的磷元素淋失量的大小顺序为LpH5.5>LpH4.5>LpH3.5>LpH6.5;在同种酸度下,施用了化肥和混合肥(化肥+有机肥)的土壤,磷元素的淋失量相对较大,而不施肥的对照土壤和加了有机肥的土壤,磷元素淋失量较小。 |
| 关 键 词： | 模拟酸雨 土柱 肥料 磷元素 淋失量 酸度 |

| Abstract: | Through soil columns leaching, the effect of different simulated acid rain on the leaching amount of phosthorus in Chongqing grey purple soil with different fertilizers was investigated. The leaching amount of phosthorus in the soil changed with the acidity of simulated acid rain and generally was in an order: LpH5.5>LpH4.5>LpH3.5>LpH6.5. Fertilizer kinds, including chemical, organic or mixed fertilizer, also influenced the leaching characteristics of the soils. More phosphorus leaching was found in the soil applied chemical or mixed fertilizer than that in the soils without chemical or mixed fertilizer. |
| Keywords: | simulated acid rain soil column fertilizer phosphorus leaching amount acidity |
