摘要: 运用农业技术转移决策支持系统(DSSAT)模型分析华北地区未来气温变化对温室番茄生产潜力的影响,为番茄种植管理的可持续发展提供思路。以华北地区田间试验数据为基础,验证DSSAT模型的适用性,模拟在气温升高条件下温室番茄的生长发育,并分析了气温变化对番茄耗水量、产量和水分利用效率的影响。经过品种参数调试校正,模型的模拟值与试验的实测值吻合度较高,可用于华北地区温室番茄的研究。模拟结果得出,随着气温升高,番茄的耗水量、产量和水分利用效率均呈下降趋势,气温升高对番茄生长不利。当气温增加1 ℃时,需要增加5%~20%的水氮用量才能基本达到原有番茄产量;当气温增加2 ℃时,需要增加10%~25%的水氮用量才能达到原有产量;当气温增加3 ℃时,需要增加15%~25%的水氮用量才能达到原有产量。同时,增加灌溉定额和氮肥用量超过一定程度会对番茄生长产生负面影响。气温升高对华北地区温室番茄的产量和水分利用效率具有一定的负面影响。本研究结果可为华北地区温室番茄生产提供高产、高效和可持续发展的技术支撑。

Abstract: The DSSAT model was employed to assess the influence of future temperature changes on greenhouse tomato production potential in North China, aiming to guide sustainable management practices. Model applicability was validated using field trial data in the region. The model accurately simulated the growth and development of greenhouse tomatoes under rising temperatures, and analyzed the impacts on water consumption, yield, and water use efficiency. Through varietal parameter calibration, simulated values aligned well with experimental measurements, demonstrating the model’s suitability for studying greenhouse tomatoes in North China. Results indicated a decreasing trend in water consumption, yield, and water use efficiency with rising temperatures, highlighting the adverse effects of temperature increase on tomato growth. When the temperature increased by 1 ℃, it was necessary to increase the amount of water nitrogen by 5%-20% to basically reach the original tomato yield; when the temperature increased by 2 ℃, it was necessary to increase the amount of water nitrogen by 10%-25% to reach the original yield; when the temperature increased by 3 ℃, it was necessary to increase the amount of water nitrogen by 15%-25% to reach the original yield. Exceeding specified levels in irrigation and nitrogen fertilizer usage can adversely impact tomato growth. Elevated temperatures negatively affect both yield and water use efficiency of greenhouse tomatoes in North China. The study results offer valuable technical support for achieving high-yield, high-efficiency, and sustainable greenhouse tomato production in the region.
