Abstract
Six years old“Blomidon”lowbush blueberry cultured on dark brown forest soil was se-lected and N(NH4NO3 ), NP((NH4)2PO4) and NPK compound fertilizer were applied in soil in twoyears.The result indicated that soil-applying N fertilizer increased the growth but decreased yield ofblueberry.Soil-applying NP and NPK compound fertilizer not only increased the growth but also in-creased the yield of blueberry. Leaf analysis showed that leaf N, K and Mn content were increased butleaf Ca and Mg content were decreased by all fertilizer treatment. Soil-applying N fertilizer decreasedleaf P but soil-applying NP and NPK fertilizer increased leaf P. According to the result, N fertilizer isnot benefit to blueberry culture, and NP and NPK fertilizer are benefit to blueberry culture. The suitableapplying amount of NP and NPK compound fertilizer is 500 to 1000 kg/hm2.
