不同规格组装式日光温室温度环境及生产性能分析

Analysis of Temperature Environment and Production Performance of Solar Greenhouses Assembled with Different Specifications

组装式日光温室近年来在甘肃省得到推广应用,对甘肃省靖远县建造的4种不同规格组装式日光温室温度环境性能进行观测。结果表明,4种组装式日光温室由于建造参数不同,温度条件差别较大,1月最低温度相差4.1℃;组装式日光温室具有升温速度快、降温速度也快的特点,1月平均升温幅度较土墙温室高2.4~5.6℃,平均最高温度可达35.7℃,平均最低温度5.7~9.8℃,较土墙温室低1.2~5.3℃;随外界气温回暖,3月组装式日光温室温度条件优于土墙温室。甘肃省靖远县组装式日光温室1月适宜叶菜生产;2月以后,随天气回暖和温室条件的改善,可进行早春茬茄果类和瓜类蔬菜生产。

The assembled solar greenhouse has been widely applied in Gansu Province in recent years. This paper carried out observation on temperature environment performance of 4 kinds solar greenhouses assembled with different specifications,built in Jingyuan County,Gansu Province. The results indicated that these 4 kinds of assembled greenhouses had very different temperature conditions,due to the different parameters of greenhouse construction. In January,there were 4.1 ℃ differences in minimum temperature. Temperature in the assembled solar greenhouse rose and cooled rapidly. In January,the average temperature rising in assembled solar greenhouse was 2.4-5.6 ℃ higher than that of the ordinary solar greenhouse. The average maximum temperature could even reach 35.7 ℃,and average minimum temperature was 5.7-9.8 ℃,1.2-5.3 ℃ lower than that of the ordinary solar greenhouse. Along with the rise of outside temperature,the temperature condition in March at assembled solar greenhouse was generally better than that of the ordinary solar greenhouse. The assembled solar greenhouses in Jingyuan County of Gansu Province were suitable for producing leafy vegetables in January. After February,along with the rise of outside temperature and improvement of greenhouse conditions,the production of early spring solanaceous fruit vegetables and cucurbits should be the first choice.
