摘　　要：研究田间喷施不同浓度醋酸钙对"丰香"草莓头茬果、二茬果和叶片10种营养元素含量的影响,并探明喷钙浓度与草莓果实及叶片营养元素含量间的相关性。结果表明:喷钙明显增加果实和叶片钙、氮、锌、锰含量,外源钙浓度与叶、果中钙、氮、锌、锰含量间基本上呈较显著至极显著正相关;喷钙降低果实钾含量和头茬果期叶片的硼含量,其喷钙浓度与果实钾含量间呈极显著负相关,与头茬果期叶片硼含量间呈较显著负相关;果实和叶片的其余元素(磷、镁、铜、铁)含量基本上与喷钙浓度相关性不显著。A field trial was undertaken to evaluate the effects of various rates of calcium acetate （Ca（CH3COO）2. H2O） solution on the contents of nutrient elements in fruits and leaves of ‘Fengxiang’ strawberry, as well as the correlation between concentration of calcium applied and contents of nutrient elements in fruits and leaves of strawberry. The results showed that the contents of Ca, N, Zn and Mn in the leaves and fruits increased significantly when the strawberry was treated with the calcium spray, and that the concentration of the exogenous calcium sprayed had positive significant relationship to the contents of Ca, N, Zn and Mn in the leaves and fruit. The K content in the fruit of the first and second crops and the B content in the leaves of the first crop decreased significantly when the strawberry was treated with the calcium spray. The concentration of the exogenous calcium sprayed had significantly negative correlation to the K content of the fruit, and had extremely significantly negative correlation to the B content of the leaves. The contents of P, Mg, Cu and Fe had no significant correlation to the calcium concentration sprayed.
