蚯蚓和微生物对土壤养分和重金属的影响

Effects of Earthworm and Micro-organism on Soil Nutrient and Heavy Metal

蚯蚓和微生物是重要的土壤生物,对提高土壤生态系统的稳定性和改变土壤养分及重金属的有效性有重要影响。本文综述了蚯蚓和微生物在改善土壤结构、调控土壤养分等方面的作用,以及它们通过吸附、富集、沉淀、溶解、氧化还原等行为,对重金属生物有效性产生的影响,目的是为现代农业生产提供一定的理论依据。

Earthworm and micro-organism are very essential soil biotas. They play an important role in the stability of eco-system and the bio-availability of nutrient and heavy metals in soil. This article reviewed the function of the earthworm and the micro-organism in improving soil structure and controlling soil nutrients, as well as their effects on the bio-availability of heavy metals in soil via bio-sorption, enrichment, precipitation, dissolution and oxidation-reduction. The aim is to provide a certain theoretical basis for modern agricultural production.
