Abstract:: In order to examine the effects of straw amendment on soil dissolved organic carbon, nitrogen and mineral nitrogen, 4 treatments were set up, which included CK (no straw), M₂ (2 g of straw in 100 g soil), M₄ (4 g of straw in 100 g soil) and M₆ (6 g of straw in 100 g soil). The straw and soil were mixed evenly, the soil water was kept 70% of water holding capacity, then the incubation experiment was conducted at room temperature (25℃), and soil moisture was controlled by weighing. Soil samples were taken in 15 d, 30 d, 45 d, 60 d, 105 d and 150 d, respectively. The results showed that the 4 treatments had the same change trend in terms of soil dissolved organic carbon(DOC) and dissolved organic nitrogen(DON), upward trend was observed at first, then DOC and DON went down, and leveled off after a period of fluctuation. The soil levels of DOC and DON of M₄ and M₆ treatments were significantly higher than CK. Ammonium nitrogen content had no obvious difference among all treatments in the same period. The contents of nitrate nitrogen significantly decreased after straw was added into soil compared with the CK.
