摘要
通过模拟酸雨淋洗土壤,造成土壤酸化和盐基流失.将小麦幼苗栽培于由酸雨致酸的土壤,其体内的碳素代谢和氮素代谢受到抑制,从而导致体内可溶性糖含量和含N量下降.其中致酸土壤对根系碳素代谢和氮素代谢的抑制作用大于对茎叶碳素代谢和氮素代谢的抑制作用.
Leaching of soil by simulated acid rain made soil acidified and base ions lost. If wheat seedlings were planted in such acidified soil, their C-metabolism and N-metabolism were restrained, and their soluble sugar and nitrogen contents reduced. The restriction of the acidified soil to C-metabolism and N-metabolism of the wheat root system was larger than that to those of stems and leaves. Tab 4, Ref 23
