模拟酸雨淋溶下中原地区幼褐土壤中营养元素的流失规律研究
Law of Nutrient Elements Leached from Soils by Simulated Acid Rain in Central Plain
摘要
Abstract
[Objective] In order to provide the scientific basis for the comprehensive control of soil nutrient deficiency and soil acidification , the effects of acid rain on the characteristics of main nutrient elements in soils were studied. [ Method] The releasing test of some nutrient elements from soils which were collected from Zhengzhou was studied by simulated acid rain leaching of soil indoor. [ Result] Leaching amounts of the three nutrient elements all decreased with the increase of pH of the simulated acid rain,and no significant differences existed in P and K leaching amounts. The contents of N, P, K increased with the decrease of leaching rate of the simulated acid rain. In the same pH and the same rate, the leaching loss of soil nutrient element was in the order of N > P > K. [ Conclusion] Strong acid rain enhanced leaching losses of nutrition elements. P and K werent sensitive to acid rain. The qualification of the soil became more serious for the treatment of acid rain for a long time .关键词
