Abstract Interaction of phosphorus (P) and zinc (Zn) is a crucial factor affecting crop yield in agricultural production. A greenhouse experiment was established to investigate the effects of P (0, 25, 50, 100, 200 and 400 mg kg−1), Zn (0, 2.5, 5 and 10 mg kg−1) and their interaction on dry matter accumulation, P and Zn concentration and their uptake in chia (Salvia hispanica L.). The application of P significantly increased dry matter by 6.3-fold over the control, while Zn treatment resulted in a 1.2-fold increase. The effect of P and Zn interaction was significant on dry matter, P and Zn concentration and their uptake. Dry matter did not respond to Zn application at low P doses, however, chia plants produced 8-fold higher dry matter at high levels of P and Zn compared to the control. Although P and Zn application showed a positive effect on chia growth, high levels of P drastically decreased Zn concentration. The application of P up to 100 mg P kg−1 enhanced Zn uptake significantly, but additional P doses resulted in a decrease. It is concluded that a balanced fertilization of P is rather important to prevent Zn deficiency and improve chia growth.

磷（P）和锌（Zn）对奇亚籽干物质、磷、锌浓度和吸收的相互作用影响

摘要 磷（P）和锌（Zn）的相互作用是农业生产中影响作物产量的关键因素。建立温室试验以研究 P（0、25、50、100、200 和 400 mg kg-1）、Zn（0、2.5、5 和 10 mg kg-1）及其相互作用对干物质积累的影响, P 和 Zn 浓度及其在奇异果中的吸收 (Salvia hispanica L.)。与对照相比，磷的施用显着增加了 6.3 倍的干物质，而锌处理导致了 1.2 倍的增加。P和Zn相互作用对干物质、P和Zn浓度及其吸收的影响显着。干物质在低 P 剂量下对 Zn 施用没有反应，然而，与对照相比，在高 P 和 Zn 水平下，奇亚植物产生的干物质高 8 倍。尽管磷和锌的施用对奇亚籽的生长有积极影响，但高水平的磷会显着降低锌浓度。施用高达 100 mg P kg-1 的 P 显着增强了 Zn 吸收，但额外的 P 剂量导致减少。结论是，平衡施磷对于防止缺锌和促进奇亚籽生长非常重要。
