摘要
蚯蚓以其特有的生物学特性,在自然和农田生态系统中发挥着重要作用。研究发现蚯蚓能指示土壤肥力、土壤环境的污染和土壤的水分状况;同时蚯蚓能促进微生物与其它土壤动物活动,促进有机残落物的机械破碎与消化分解,提高土壤的肥力水平。
Earthworm play an important role by its special biological characteristics in natural and farmland ecosystem. Research shows that earthworm can indicate Soil Fertility, Soil Environmental Pollution and water regime of Soil; meanwhile, earthworm may promote activity of microorganism and other soil animals, advance mechanical crushing and digestion decomposition of organic debris and improve fertility level of Soil.
