一种新型日光温室与传统四种日光温室性能及投资对比研究

Comparative Study of Four New Solar Greenhouse With Traditional Performance and Investment in Greenhouse

以新型双屋面日光温室和传统的4种日光温室进行性能对比研究,选取了2012年12月21日(冬至日)、12月23日(典型晴天)、2013年1月19日(典型阴天)和2014年1月21日16:00至1月22日14:00的试验数据,进行室内光照强度、气温、地温、相对湿度以及造价、空间、寿命等性能分析。研究新型双屋面日光温室的性能,为广大种植户寻求一种优化的温室结构。结果表明:新型日光温室与3种砖墙日光温室平均相比,室内平均气温提高了1.3℃,室内平均地表下0.1m处地温提高了1.7℃,室内平均光照强度降低了1.25%,室内平均相对湿度提高了3.98%;新型日光温室与寿光式土墙日光温室相比,室内平均温度降低了2.0℃,室内地温降低了0.2℃;新型日光温室造价较3种砖墙日光温室造价平均降低了38.68%,较寿光式土墙日光温室造价降低了9.12%;新型日光温室土地利用率较砖墙温室土地利用率平均提高了9.17%,较寿光式土墙日光温室土地利用率提高了44.01%。新型日光温室较砖墙温室温度高,相对湿度高,光照强度接近,跨度大,寿命优于土墙和砖墙温室;是一种优化的温室结构。

A comparison study about new double roof solar greenhouse and traditional four solar greenhouse was conducted the experimental data of December 21 st,2012（winter solstice）,December 23th（typical sunny）,January 19,2013（typical cloudy）and from at 16：00on January 21 st,2014to at 14：00on January 22 th,the performance of indoor light intensity,temperature,ground temperature,relative humidity,and the cost,space,life and other research new dual roof solar greenhouse performance was studied,to seek a optimizatal greenhouse structure,for the majority of growers.The results showed that the new solar greenhouse with three kinds of brick wall in greenhouse average compared：indoor average temperature increase of 1.3℃,the indoor underground 0.1mat an average ground temperature improved 1.7℃,the average indoor light intensity low of 1.25%,the average indoor relative humidity improved 3.98%;new solar greenhouse Shouguang formula compared to the average temperature of the walls greenhouses low 2.0℃,indoor ground temperature low 0.2℃;the new solar greenhouse cost representing three kinds of brick in greenhouse cost reduced by an average38.68%,compared with the cost of solar greenhouse Shouguang style walls reduced 9.12%;new solar greenhouse land usage was brick greenhouse land utilization rate increased by an average 9.17%,compared with Shouguang formula walls in greenhouse land utilization by 44.01%compared with the brick wall of new solar greenhouse temperature,high relative humidity,light intensity close to the span,life was better than brick walls and greenhouses;.was an optimization of the greenhouse structure.
