Abstract: The three-year-old Paeonia ostii ‘Fengdan’ plants is used as the material to carry out the comparative test on the base fertilizer application, the fertilizer treatments of oil cake(0.1,0.5,1.0 kg), cow dung (0.1,0.5,1.0 kg) and the cow dung(0.1、0.5、1.0 kg)+compound fertilizer(0.1 kg) are respectively applied to each plant. In the after fertilizer test, the saplings of Paeonia ostii ‘Fengdan’ were used, and each sapling was applied with high nitrogen compound fertilizer 10 g,30 g and 50 g,respectively. The growth indexes of plant, growth indexes of leaf and chlorophyll content in leaf were determined to evaluate the efficiency of different fertilizer treatments. The results showed that the effects of the three kinds of base fertilizer treatments on growth of oil peony plants were cow dung+compound fertilizer>cow dung>oil cake. The fertilizer treatment cow dung(0.5 kg)+compound fertilizer (0.1 kg) showed the most obvious promoting effect. In the after fertilizer test, the application of 10 g compound fertilizer supported great growth of oil peony plants in plant height, stem width, branch number and leaf amount. In general, the base fertilizer treatment applying cow dung (0.5 kg)+compound fertilizer (0.1 kg) had the best benefit on the growth of the three-year-old plants of Paeonia ostii ‘Fengdan’, and the after fertilizer treatment applying compound fertilizer (N∶P∶K=25∶5∶10) 10 g had the best effect on the growth of the Paeonia ostii ‘Fengdan’ saplings.

Key words: Paeonia ostii ‘Fengdan’, base fertilizer, after fertilizer, plant growth, chlorophyll content
