Evaluation Of Solar Greenhouse Performance And Vegetables Crops Arrangements In Yopurga County

Solar greenhouse is widely applied in northwestern China,and is one of the main agricultural facilities in China.This test selected 3 kinds of solar greenhouses as the materials,and studied the structural parameters,temperature,relative humidity,light intensity and other environmental parameters of solar greenhouses to compared the performance with solar greenhouses,to find a applicable patten,and to provide references for the development of solar greenhouse in Yopurga County.Besides that,this text investigated and analyzed the vegetables crops arrangements of solar greenhouses in Yopurga County.The result as follows:(1)The wall of the 3 types greenhouses in Yopurga County were ordinary wall,the coverings were heat preservation quilts.GreenhouseⅠwas the non-slope bamboo structure with poor thermal insulation properties.GreenhouseⅡwas steel frame without column structure with better thermal insulation properties than greenhouseⅠ.GreenhouseⅢwas not only steel structure,but also equipped with one rows of columns with the strongest stability.Besides,GreenhouseⅢthe thickness of the rear wall of the greenhouse was more than I,II,and the insulation performance was better,the most suitable for winter vegetable production.(2)The greenhouse is greatly influenced by external climate,and weather,etc.In the same weather condition,the solar greenhouse environment with different structure showed a certain difference.The average temperature of the highest temperature in the day was No.Ⅱgreenhouse>No.Ⅲgreenhouse>No.Ⅰgreenhouse,No.Ⅲgreenhouse the highest light intensity incoverage at night>10℃,and it could take production in winter.The daily average light intensity was No.Ⅲgreenhouse>No.Ⅰgreenhouse>No.Ⅱgreenhouse.The daily average humidity in the solar greenhouse of I,II and III were No.Ⅰgreenhouse(71.9%)>No.Ⅱgreenhouse(69.9%)>No.Ⅰgreenhouse(65.7%).Considered the light and temperature environment,the suitable in Yuepuhu County was No.III solar greenhouse.(3)There were 2 mainly kinds of vegetables crops arrangements in Yopurga County inclunding of the winter crossing pattern in accounting of 20%;and autumn delaying to early spring pattern in accounting of80%.(1)High-yielding and high-efficiency cultivation pattern of autumn-delaying pumpkin-prevernal pepperWith this cultivation pattern,the productions were as follow:the first harvest of winter-crossing pumpkin was 4760kg/667m~2,the second harvest of early-maturing pepper was 3790kg/667m~2,and the total annual income was 34187 Yuan/667m~2.(2)High-yielding and high-efficiency cultivation pattern of winter-crossing tomato-cabbageWith this cultivation pattern,the first harvest of autumn-delaying tomato was 7940kg/667m~2,the second harvest of early-maturing cabbage was 3420kg/667m~2,with the total annual income was28953Yuan/667m~2.(3)High-yielding and high-efficiency cultivation pattern of autumn-delaying tomato-prevernal melonWith this cultivation pattern,the first harvest of autumn-delaying tomato was 7730kg/667m~2,the second harvest of early-prevernal melon was 2930kg/667m~2,with the total annual income was27187Yuan/667m~2.
