摘要: 以三年生凤丹(Paeonia ostii ‘Fengdan’)油用牡丹为材料进行基肥施用比较试验,每株分别施用油枯(0.1、0.5、1.0 kg)、牛粪(0.1、0.5、1.0 kg)、牛粪(0.1、0.5、1.0 kg)+复合肥(0.1 kg);以凤丹油用牡丹幼苗为追肥施用比较试验材料,每株分别施用高氮复合肥10、30、50 g,研究了施用不同基肥及追肥对油用牡丹凤丹植株生长指标、叶片生长指标、叶片叶绿素含量的影响。结果表明,3种基肥对油用牡丹植株生长的促进作用为牛粪+复合肥>牛粪>油枯,其中以牛粪(0.5 kg)+复合肥(0.1 kg)的促进作用最为明显;在追肥试验中,施用10 g复合肥对幼苗株高、茎粗、分枝数、叶片数等生长指标的促进效果最佳。基肥施用牛粪0.5 kg+复合肥(0.1 kg),追肥施用复合肥(N∶P∶K=25∶5∶10)10 g/株对油用牡丹凤丹的生长促进效果最好。

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
