摘　　要：通过灌溉含有NaCl和CaCl2的微咸水玉米微区试验,分析了微咸水中NaCl浓度和CaCl2浓度对玉米生长特性和产量的影响。研究表明:灌溉不同NaCl浓度和CaCl2浓度的微咸水下,玉米的株高和叶面积随着生长时间的延长而增大;在相同生长时间里,玉米的株高和叶面积随着微咸水中NaCl浓度的增高而逐渐减小,随着微咸水中CaCl2浓度的增高而逐渐增大,但影响规律没有NaCl明显。玉米单株产量随着微咸水中NaCl浓度的增高而逐渐减少,而随着微咸水中CaCl2浓度的增高而逐渐增加。以上研究可以为盐碱地农作物种植提供理论依据。Through the maize micro-plot trials of saline water irrigation with different concentration of NaCl and CaCl2,the effect of the NaCl concentration and CaCl2 concentration on the maize growth characteristics and yield is analyzed.The results show irrigation with different concentration of NaCl and CaCl2,maize plant height and leaf area increased with the growth time.The maize plant height and leaf area decreased with NaCl concentration increasing at the same growth time,while the maize plant height and leaf area increased with CaCl2 concentration increasing,but which is not very significant comparing to the maize.The maize yield decreased with NaCl concentration increasing and increased with CaCl2 concentration increasing.The above study can provide a theoretical basis for the saline crops.
