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℃。
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 green-house. 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.
