摘要

摘要本研究旨在测定蚯蚓堆肥对伊朗北部农业生态系统土壤理化性质和径流质、量的影响。因此,在5个月的自然降雨条件下,在坡地设置1 × 5 m的径流测量地块。测量了径流的质量和数量、土壤性质和植物生长情况。本研究表明,施肥处理(单独施用蚯蚓堆肥、单独施用化学施肥或它们的混合施肥)对径流水量及其质量(沉积物产量、硝酸盐含量、pH值和电导率)没有影响,除了试验的第一个月,单独施用蚯蚓堆肥时测得的径流量较低。虽然蚯蚓堆肥对植物生长没有影响,但我们的研究结果表明,蚯蚓堆肥作为肥料对土壤性质有显著改善。因此,本研究表明蚯蚓堆肥可被视为减少化肥使用和改善土壤性质的替代应用,但其对植物生长和径流的影响仅限于短期。

Effect of Vermicompost on Soil and Runoff Properties in Northern Iran
Abstract This study aimed at measuring the effect of vermicompost on soil physical and chemical properties and runoff quality and quantity in agro-ecosystems in Northern Iran. Thus, runoff measurement plots of 1 × 5 m were set up in sloping lands under natural rainfall during 5 months. Runoff quality and quantity, soil properties, and plant growth were measured. This study shows that the amount of runoff water and its quality (sediment yields, nitrate content, pH, and conductivity) were not influenced by the fertilization treatments (vermicompost alone, chemical fertilization alone, or their mixture), except for the first month of the experiment where a lower runoff amount was measured when vermicompost was applied alone. Although no difference in plant growth was found, our results showed a significant improvement of soil properties when vermicompost was used as a fertilizer. Consequently, this study shows that vermicompost can be considered as an alternative application for reducing the use of chemical fertilizers and improving soil properties but its impact on plant growth and runoff is limited to the short term.
