摘要:
 以油用牡丹品种‘凤丹’为试验材料，研究硼肥、锌肥作为叶面肥喷施对其光合特性、叶片矿质元素含量、叶绿素含量的影响，为合理的油用牡丹栽培施肥技术提供理论依据。结果表明，叶施硼肥和锌肥能有效的增大自然状态下‘凤丹’日平均净光合速率（Pn）和气孔导度（Gs），单施硼肥、单施锌肥和硼锌配施日平均净光合速率较对照组分别高16.46%、19.35%和37.43%，增大了光合产物的积累。通过模型对光响应曲线和CO2响应曲线进行拟合得出喷施硼肥和锌肥能够显著增大‘凤丹’潜在光合能力Pnmax值和Amax值，最大值分别可达15.12 μmol·m-2·s-1和34.59 μmol·m-2·s-1，同时对其表观量子效率（AQY）、初始羧化效率（ACE）、光饱和点（LSP）和CO2饱和点（CSP）也有所提高，使其能够适应更宽广的光照强度和CO2浓度范围。施用硼肥和锌肥叶片叶绿素含量（Chl）有显著提高，Chla/Chlb值增大；对叶片矿质元素氮、磷、铁、锰、硼、锌含量影响较大。所有结果均以硼肥和锌肥配合施用效果最佳。
Abstract:
 Taking common variety of Paeonia ostii ‘Feng Dan’ as material,and using foliar spray method,the effects of boron and zinc fertilizer on photosynthetic characteristics,mineral elements content and chlorophyll content in leaf were examined to provide theoretical basis for the rational cultivation and fertilization of oil tree peony.The results showed that foliar fertilization with boron and zinc could effectively increase daily average net photosynthetic rate efficiency (Pn) and stomatal conductance (Gs) of ‘Feng Dan’ under natural conditions.The average net photosynthetic rates of single use of boron,zinc and combined use of both elements were 16.46%,19.35% and 37.43% higher than that of the control,which increased the accumulation of photosynthetic products.Through fitting the model to the light response curve and the CO2 response curve,it was found that spraying boron and zinc fertilizer could increase the potential photosynthetic capacity Pnmax and Amax of ‘Feng Dan’ significantly,with the maximum values of 15.12 μmol· m-2·s-1 and 34.59 μmol·m-2·s-1,and at the same time,its apparent quantum efficiency (AQY),initial carboxylation efficiency (ACE),light saturation point (LSP) and CO2 saturation point (CSP) were also improved,allowing it to adapt to a broader range of light intensity and CO2 concentration range.The chlorophyll content (Chl) increased significantly through spraying boron and zinc fertilizer,and the value of Chla/Chlb was also improved.The application of boron and zinc also affected the contents of the mineral elements in the leaves with different degrees,especially nitrogen,phosphorus,iron,manganese,boron and zinc.All results were the best in the combined application of boron and zinc fertilizer.
