通过田间试验与不同玉米品种的示范试验,考察了“3+N”抗盐碱技术模式对玉米出苗率、农艺性状、产量及经济效益的影响。田间试验结果表明:“3+N”抗盐碱技术处理的玉米株高、穗粗等农艺指标均得到优化,玉米出苗率、产量较常规施肥处理的显著提高13.3%、24.1%;生产成本增加52元/亩(1亩=667 m2),纯收入增加366.2元/亩。示范试验结果表明:佳良0987和先玉1321表现出更强的适应性和更好的经济效益。“3+N”抗盐碱技术模式兼具技术高效性与经济合理性,为盐碱地玉米高效栽培提供了科学依据与实践路径。
Through field experiment and demonstration trial with different maize varieties, the effects of the "3+N" saline-alkali resistance technology model on maize emergence rate, agronomic traits, yield, and economic benefits are investigated. Field experiment results show that: the "3+N" technology optimizes agronomic indicators, such as plant height and ear diameter, significantly increases maize emergence rate and yield by 13.3% and 24.1%, respectively, compared to conventional fertilization treatment, while production costs increases by 52 yuan/mu (1 mu=667 m2), net income increases by 366.2 yuan/mu. Demonstration trial shows that Jialiang 0987 and Xianyu 1321 exhibite stronger adaptability and better economic benefits. The "3+N" technology model demonstrates both technical effectiveness and economic rationality, providing a scientific basis and practical pathway for efficient maize cultivation on saline-alkali land.
