Abstract:
Taking compound fertilizer and the new planting blueberry pot seedling as test materials，different amount of compound fertilizer and different periods after fertilization were applied,changes of the soil properties of blueberries pot seedling，plant growth and leaf nitrogen content were determined at the same time.The results showed that different amount of compound fertilizer on soil pH value had little impact in the short term，the soil electrical conductivity and available N increased by the increasing fertilizer used，nitrogen content increased to a certain degree，blueberries appeared dead plants.The maximum period of conductivity and available N was not consistent.0.2 g/plant was the best compound fertilizer treatment to blueberry seedling,under this treatment,plant growth optimal was the electrical conductivity of less than 1 000 μS/cm，available N content in 100-150 mg/kg.Leaf nitrogen content increased with increment of fertilizer use，and soil available N content were positively.
