摘要： 为研究新型双连双拱双膜塑料大棚温度场分布及其保温性能问题，基于2016 年3 月8—10 日的新型双连双拱双膜塑料大棚内外GL820 绝缘多通道数据记录仪、中长图彩色无纸记录仪、光电式总辐射传感器V2.0 的温度、光照记录数据，应用MATLAB软件进行二维温度场的拟合和图像绘制。结果表明：06:01 为大棚最低温度，最低气温9 日＞8 日＞10 日；08:01—12:01 为温度上升期；8 日、10 日12:01—16:01为大棚最高温度，9日14:01—16:01为大棚最高温度；22:01温度8日、10日＞9日。阴天的8日或阴~晴的9 日09:01 先从大棚的下部升温，12:01—16:01 大棚上部升温较快，20:01—22:01 大棚上部降温较快；晴天的10 日9:01 先从大棚的上部升温，12:01—16:01 是3 天的最高温度，18:01 从大棚下部开始降温，20:01—22:01 大棚上部气温最低。在大棚温度最低时或最高时，大棚顶部最高点对应为大棚温度最低点或最高点。夜间00:01—08:01 期间10 cm地温较低，地温8 日＞9 日＞10 日；10 日07:00—08:00 地温 最低(11.3℃)。棚内、外光照强度差距较大，光照强度10 日＞8 日＞9 日。双连双拱双膜塑料大棚在2 月中旬喜温果菜类可以定植，早于单膜塑料大棚25~30天，在春提早方面优势明显。

Abstract: The paper aims to study the temperature field distribution and insulation performance of a new double-span and double-film covered plastic greenhouse. It was based on the temperature and light recording data from GL820 insulated multi- channel data recording, medium- length color paperless recorder, photoelectric total radiation sensor V2.0 in the new double-span and double-film covered plastic greenhouse on March 8, 9, and 10, 2016. The MATLAB software was used to fit the two-dimensional temperature field and image rendering. The results showed that 06:01 had the minimum temperature inside the greenhouse. The lowest temperature was March 9> March 8> March 10. 08:01 to 12:01 was the temperature rising period. On March 8 and 10, 12:01 to 16:01 had the highest temperature inside the greenhouse, and on March 9, 14:01 to 16:01 had the highest temperature inside the greenhouse. The greenhouse temperature at 22:01 was March 8 and March 10> March 9. The temperature rose from the lower part of the greenhouse at 09:01 on the cloudy day March 8 and the cloudy and sunny day March 9. The upper part of the greenhouse warmed up faster from 2:01 to 16:01. The upper part of the greenhouse cooled faster from 20:01 to 22:01. The temperature rose from the upper part of the greenhouse from 9:01 on the sunny day March 10. 12:01 to 16:01 had the highest temperature for 3 days, and the lower part of the greenhouse started to cool down at 18:01. The temperature in the upper part of the greenhouse was the lowest from 20:01 to 22:01. When the greenhouse temperature was the lowest or the highest, the temperature of highest point on the top of the greenhouse was corresponding to the greenhouse temperature. During the night from 00:01 to 08:01, the soil temperature was relatively low. The soil temperature under 10 cm was March 8> March 9> March 10. From 07:00 to 8:00 on March 10, the soil temperature under 10 cm was the lowest (11.3℃). There was a big gap between the light intensity inside and outside the greenhouse, and the light intensity was March 10> March 8> March 9. The thermophilic fruit vegetables could be planted in the middle of February in double- span and double- film covered plastic greenhouse, 25- 30 d earlier than the single- film plastic greenhouse. It has obvious advantages in arly planting in spring.
