| 为明确塑料大棚生产中常用降温措施的降温效果，针对遮阳网、2种型号的环流风机单项及组合降温措施对塑料大棚内温度的影响进行了研究。结果表明：单项降温措施中遮阳网的降温效果最好，使棚室平均温度和最高温度比环流风机（JHF-500）分别再降低0.8℃和1℃左右；组合降温措施中，遮阳网结合环流风机JHF-500的降温效果最好，可使棚室内最高温度较遮阳网单项降温措施再降低2.0℃左右。建议结合具体气候条件、基础设施条件、运行成本等因素综合考虑，选取经济有效的降温技术，使棚室在炎热的夏季达到理想的降温效果，为作物提供良好的生长环境。 |

| Abstract: In order to determine the cooling effect of common cooling measures in the production of plastic greenhouse, the influence of single and combined cooling measures using sunshade and two types of circulating fans on the temperature in plastic greenhouse were researched. The results showed that the sunshading had the best cooling effect in the single cooling measure, which made the average temperature and the maximum temperature of the shed reduce about 0.8 ℃ and 1 ℃ compared with the circulation fan (JHF-500), respectively. The sunshading combined with the circulation fan JHF-500 had the best cooling effect in the combined cooling measure, which could reduce the maximum temperature about 2.0 ℃ compared with the single cooling measure of the sunshading. The economical and effective cooling technology was suggested, which should be selected in combination with local climatic conditions, infrastructure conditions and operation costs and other factors, so that the shed could achieve the ideal cooling effect in hot summer and provided a good growth environment for crops. |
