摘　　要：针对秋延后辣椒在湖南地区生产时易发生高温障碍的现状,对传统大棚的结构进行了优化,并以传统大棚为对照,比较分析了二者的结构、室内温度变化及其对秋延后辣椒种植的影响。结果表明,在8月20日至9月26日,优化大棚室内白天平均气温明显低于传统大棚,其降温效果优于传统大棚,而在9月27日至11月30日,优化大棚室内白天平均气温则明显高于传统大棚,优化大棚的保温效果优于传统大棚;优化大棚的室内夜晚平均气温在8月20日至11月8日明显低于传统大棚,而在11月9~30日则高于传统大棚;优化大棚的秋延后辣椒种植效益也明显高于传统大棚。与传统大棚相比,优化大棚可显著提高秋延后辣椒的单果质量和单株产量,667 m^(2)产量显著提高11.3%。In view of the current situation of high temperature obstacle in the pepper production in late autumn in Hunan area,the structure of the traditional plastic greenhouse was optimized,and the structure,indoor temperature change and its effect on the pepper cultivation in late autumn were compared and analyzed with traditional greenhouse as the control.The results showed that from August 20th to September 26th,the average daytime temperature in the optimized plastic greenhouse was significantly lower than that in the traditional plastic greenhouse,its cooling effect was better than that of the traditional plastic greenhouse.While from September 27th to November 30th,the average daytime temperature in the optimized plastic greenhouse was significantly higher than that in the traditional plastic greenhouse,its heat preservation effect was better than that of the traditional plastic greenhouse.The average night temperature in the optimized plastic greenhouse was obviously lower than that in the traditional plastic greenhouse from August 20th to November 8th,while its average night temperature was higher than that in the traditional plastic greenhouse from November 9th to November 30th.The pepper cultivation benefit in late autumn of the optimized plastic greenhouse was also significantly higher than that of the traditional plastic greenhouse.Compared with the traditional plastic greenhouse,the fruit weight and yield per plant of pepper were significantly increased in late autumn in the optimized plastic greenhouse,and the 667 m^(2) yield significantly increased by 11.3%.
