摘　　要：通过对黑龙江省东宁地区的4年生平欧杂交榛(Corylus heterophylla×Corylus avellana)联合施用不同浓度的硼(0. 2%、0. 3%、0. 4%)、锌(0. 3%、0. 4%、0. 5%)肥处理,研究两种微量元素对平欧杂交榛光合生理、结实、果仁和叶片营养状态的影响。研究结果表明:(1)硼、锌对净光合速率影响显著,其交互作用对净光合速率影响极显著。(2)硼对出仁率影响极显著,对果仁重影响显著,对单果重和座果率影响不显著。锌对单果重和果仁重影响极显著,对出仁率影响显著,对座果率影响不显著。硼、锌交互作用对出仁率影响显著,对单果重、果仁重和座果率影响不显著。(3)硼、锌和其交互作用对果仁脂肪酸含量、果仁蛋白质含量影响不显著。硼、锌和其交互作用对4年生平欧杂交榛的生理和结实影响明显,提高了平欧杂交榛叶片的净光合速率,同时对果仁重、出仁率和单果重有不同程度的促进作用。本地区4年生平欧杂交榛硼、锌叶面施肥的浓度分别以0. 3%和0. 4%为宜。Through the application of different concentrations of boron(0.2%,0.3%and 0.4%)and zinc(0.3%,0.4%and 0.5%)in a 4 a hybrid hazelnuts(Corylus heterophylla×Corylus avellana)in Dongning Area of Heilongjiang Province,the effects of micronutrient fertilizers on the photosynthetic physiology,seed setting,nut kernel and leaves nutrient status of hybrid hazelnut were investigated.Boron and zinc had a significant effect on net photosynthetic rate.Interaction between boron and zinc had an extremely significant on net photosynthetic rate.Effect of boron on kernel rate was extremely significant,effect of boron on single kernel mass was significant,effects of boron on single nut mass and nut setting rate were not significant.Effects of zinc on single nut mass and single kernel mass were extremely significant,effect of zinc on kernel rate was significant,and effect of zinc on nut setting rate was not significant.Significant effect of interaction between boron and zinc was detected with kernel rate,but not with single nut mass,single kernel mass and nut setting rate.Effects of boron,zinc and interaction between boron and zinc on kernel fatty acid concentration and kernel protein concentration were not significant.Boron,zinc and the interaction had significant effects on the photosynthesis and seed setting of 4 a hybrid hazelnut trees,promoted single kernel mass,kernel rate and single nut mass.The proper concentration for boron and zinc foliar fertilization is 0.3%and 0.4%,respectively.
