Under the natural ecological condition of rape field cultivation,effect on rape soil and dissolution in the base ions of K,Na,Ca and Mg with different pH of simulated acid rain was investigated by spraying and soil columns leaching experiments.
在油菜大田栽培的自然生态环境条件下,通过喷淋和土柱淋溶试验,研究不同pH模拟酸雨对油菜大田土壤K,Na,Ca和Mg等盐基离子溶出的影响。
Significant correlation between the total amount of four kinds of base ions in the leacheate and concentration of H + of acid rain is evident.
4种盐基离子淋失总量与酸雨的氢离子浓度呈极显著的正相关关系 ,淋失量 Ca2 + >Mg2 + >Na+ >K+ ,其中 Na+对酸雨的酸度最不敏感。
