摘要: 通过对巨型大棚温度因子的观测,揭示巨型大棚温度因子变化规律,从而为巨型大棚温度调控及生产管理提供科学依据。分析结果显示:巨型大棚内11月下旬日平均气温和10 cm地温分别为10.3℃和10.6℃,3月上旬日平均气温和10 cm地温可回升至12.6℃和9.7℃。与常规大棚相比,晴天日平均气温可提高0.7℃,日温差降低2.7℃;巨型大棚加盖简易的内保温幕可提高气温和地温,其提温范围在1~2℃。

Abstract: The average air temperature and soil temperature at 10cm depth in the wide-span plastic covered tunnel greenhouse were observed to reveal the temperature changes and to provide the scientific basis for the temperature regulation in the wide-span plastic covered tunnel greenhouse.The results showed that the air and soil temperature in the wide-span plastic covered tunnel greenhouse was 10.3℃ and 10.6℃respectively during the last ten days of November,while it reached 12.6℃ and 9.7℃ respectively during the first ten days of March.The average air temperature in the wide-span plastic covered tunnel greenhouse increased by 0.7℃ and the temperature difference between day and night decreased by 2.7℃ compared with that in the normal-span greenhouse.Both air and soil temperature increased by 1-2℃ by adding a simple thermal screen in the wide-span plastic covered tunnel greenhouse.
