| 摘 要： | 通过盆栽试验，研究了寒地盐碱土施用锌肥对玉米的生长发育、光合性能及产量的影响。试验结果表明，寒地盐碱土适量施锌，可以有效促进玉米植株生长，增加干物质积累，增大玉米光合叶面积和光合速率，提高玉米产量。过量施锌导致玉米株高、叶面积、光合速率和产量下降。寒地盐碱土锌肥(EDTA-Zn)最佳施用量为30 kg/hm2。

| Abstract: | According to the pot experiment, effect of zinc fertilizer on maize of growth and development, photosynthesis character and yield was studied in saline-alkaline soil in cold region. The results showed that with adequate amount of zinc fertilizer could promote plant growth, increase dry matter accumulation, photosynthetic leaf area photosynthetic rate and yield in cold region. However, heavy zinc fertilization decreased plant height, leaf area, photosynthetic rate and yield. The optimum amount of zinc fertilizer for maize was 30 kg/ha (EDTA-Zn) in saline-alkaline soil in cold region. |
