Abstract

: This research was conducted to study the effect of different heating systems in cucumber production greenhouses in Varamin region, Tehran province, Iran on crop yield, volume and cost of gas consumed. Three types of conventional heating systems, namely the central heating system (including boiler + hot water pipes), gas heater system (including double-walled tank + blower) and traditional furnace system (including ignition chamber + torch + pipes carrying a mixture of hot air and flammable gases) were studied during two consecutive periods of greenhouse cucumber cultivation in the cold season (from January to June), and average values of crop yield, volume and cost of gas consumed were determined separately. Results of the study indicated that the central heating system with the highest crop yield (295 t  ha -1 ), and the lowest volume (100,000 m 3  ha -1 ) and cost (210,000,000 Rials  ha -1 ) of gas consumed was the best and most suitable heating system for greenhouses producing cucumbers in Varamin region and other regions with the same and similar climate as well as regions with active greenhouses in

瓦拉明地区黄瓜生产大棚不同供暖系统对作物产量、产量和用气成本的影响

：本研究旨在研究伊朗德黑兰省瓦拉明地区黄瓜生产温室不同供暖系统对作物产量、用气量和成本的影响。三种类型的常规供暖系统即中央供暖系统（包括锅炉+热水管道），在寒冷季节（1月至6月）连续两个时期的温室黄瓜栽培中，研究了气体加热器系统（包括双壁罐+鼓风机）和传统炉子系统（包括点火室+火炬+输送热空气和可燃气体混合物的管道），消耗的气体的体积和成本分别确定。研究结果表明，集中供暖系统的作物产量最高（295t ha-1），最小体积（100000 m3 ha-1）和成本（210000000里亚尔 ha-1）的温室气体消耗是瓦拉明地区和其他气候相同和相似的地区以及年温室活跃的地区生产黄瓜的最佳和最合适的供暖系统
