| 摘要：为了科学精准地调控春秋棚温度，创造适宜西瓜生长的环境，针对延庆春秋棚西瓜生产开展
棚温监测，收集同期棚外相应气象资料，分析棚内温度日变化和月变化规律以及棚内外温度的相关性。
结果表明：春秋棚保温、增温效果较为明显，春秋棚内温度与外界温度、天气状况密切相关，晴天时棚
内气温变化幅度较大，升温、降温均较明显，多云、阴天气温变化幅度较小。结合西瓜冷、冻害温度指

| Abstract: In order to control the temperature of the spring and autumn plastic greenhouse scientifically and
precisely, and create a temperature environment suitable for watermelon growth, the temperature monitoring in the spring
and autumn plastic greenhouse was carried out for watermelon production in Yanqing district. The corresponding weather
and meteorological data outside the plastic greenhouse during the same period were collected, and the diurnal and monthly
changes of the temperature inside the plastic greenhouse and the correlation between the temperature inside and outside the
plastic greenhouse were analyzed. The results showed that the effects of heat preservation and temperature increase in spring
and autumn plastic greenhouses were obvious, and the temperature inside spring and autumn plastic greenhouses was closely
related to the external temperature and weather conditions, the range of temperature changes in sunny days was large, and
the ranges of temperature rise and temperature drop were obvious, while the ranges of temperature change in cloudy and overcast days were small. Combined with cold and freezing injury temperature indicators of watermelon, statistical regression
method was used to analyze the temperature of indoor monitoring and external meteorological data under the condition of low
temperature at night in early spring, and the prediction index of cold and freezing injury at night was determined by using the
lowest temperature forecast. When the weather forecast minimum temperature was less than 8.99 ℃, there was a risk of cold
injury, and the weather forecast minimum temperature was less than 4.21 ℃, there was a risk of freezing injury, which could
be targeted to used for watermelon production in spring and autumn plastic greenhouse. |
