外源不同形态钙及钙铜同施对番茄叶片和果实钙含量及产量的影响

以番茄为材料，外源喷施不同形态钙及钙铜同时喷施，研究缺钙条件下（砂培）外源喷施不同形态钙及钙铜同施对果实和幼叶中钙含量和产量的影响。结果表明，与叶面喷施无机钙相比，钙铜同施提高了番茄叶片钙含量；与叶面喷施无机钙+铜相比，叶面喷施糖醇钙+铜，钙在生长中心和果实中的含量增加，叶面喷施糖醇钙+铜促进幼叶和果实对钙的吸收，同时延长了番茄的盛果期。

Effects of Different Forms of Exogenous Calcium and Application of Calcium and Copper on Calcium Content and Yield of Tomato

Tomato (Solanum lycopersicum Mill.) was used as the material,effect of spraying of different forms of calcium and combined with spraying of calcium and copper on calcium content and yield in young seedlings of tomato furit under calcium deficiency condition (sand culture) was studied.The results showed that compared with foliar spraying of inorganic calcium, application of calcium and copper together increased the calcium content in tomato leaves; compared with foliar spraying of inorganic calcium and copper , foliar spraying of chelator-sugar alcohol calcium and copper , calcium content in young leaves and fruit of tomato increased.Foliar spraying of chelator-sugar alcohol calcium and copper on the leaf surface promoted the absorption of calcium in young leaves and fruit, and prolonged the full fruit period of tomato.
