关于植物对红壤的酸化作用及其致酸机理

Preliminary Discussion on Red Soil Acidification Induced by Plant and Its Mechanism

土壤酸化是土壤形成过程中的一种自然的生物地球化学过程 ,植物在这一过程中起着重要的作用。本文重点从植物的矿质养分主动吸收、植物代谢产物等方面讨论了植物对红壤的酸化作用及其致酸可能机理。对全面认识红壤酸化原因 。

Soil acidification is a natural bio-geochemical phenomenon occurred in process of soil formation in which plants play an important role. In order to know better the cause of red soil acidification and acid amelioration of red soil, red soil acidification induced by plant and its mechanism were discussed. Proton secretion coupling nutrients active uptake cauld increase soil acidity. Metabolite of plants, specially for acid-tolerant plants or oligotrophic-tolerant plants, probably increase soil acidity through accelerating soil mineral decomposition.
