Abstract:
A comparison study about new double roof solar greenhouse and traditional four solar greenhouse was conducted the experimental data of December 21st,2012 (winter solstice),December 23th (typical sunny),January 19,2013 (typical cloudy) and from at 16:00 on January 21st,2014 to at 14:00 on January 22th,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 0.1 m at 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 average 38.68%,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.
