Turpan District Facilities Suitable For Greenhouse Cultivation Of Vegetables Performance Optimization Of The Structure

In recent years, the rapid agricultural development in the Turpan area facilities, facilities for the wholeregion is an area of nearly15acres of agricultural, greenhouse structure, showing a pattern ofdiversification, this paper selected the Turpan region are more representative of the six kinds of greenhouseexperiments to compare the structure, Through its main technical parameters such as arc, high-span ratio,maximum, minimum temperature, ground temperature and the construction cost statistics, analysis, and forthe local large-scale problems encountered in the construction of greenhouses, technological tests carriedout after the roof, aimed more suitable in the Turpan region identify current local conditions of light andheat, easy to build, easy to plant management, suitable for large scale structure of the solar greenhouse.1. From the perspective of greenhouse insulation, greenhouse span9m steel frame (the fourth category ofgreenhouse) compared to other types of greenhouse structures, with the temperature steady, slow cooling,better insulation, energy conservation, land utilization advantages of higher; but the fourth class ofgreenhouse heat storage in the insulation, there are still some drawbacks in the greenhouse structural designcan be increased through appropriate Hou roof elevation, reduce greenhouse back-slope, curvature andother ways to increase the shelf surface to perfect, not only can absorb the increased roof light and heat thearea, enhance the thermal insulation capacity, can also reduce construction costs, enhanced slope stability,reasonable surface curvature can shed roof surface to maximize the absorption of light and heat, to reducelight reflection, enhanced greenhouse heat storage sex, and help pull up the blanket, reducing the pressureon the roof surface. Construction procedures in the greenhouse, greenhouse supplies large-scalepreparations for the construction of the fourth category is difficult, requires a lot of labor, high labor costs,construction costs in rolling on the mechanical and manual ramming the cost of construction of2m widewall is basically the same, the use of mechanical rolling greenhouses wall, solid wall not only strong, butthe construction speed, placed after the rafters of the wall slope is not easy to lead to collapse.2. In the greenhouse structure and layout design, in order to avoid heat loss and cold air to enter the doorlocated in the back wall of the penthouse, and one end. As the next frontier digging greenhouse shade, thetemperature is low, poor crop growth, can reduce the greenhouse, digging through the appropriate depth,reducing the greenhouse front shade, table and drip irrigation facilities will be set up in front, set areasonable shed layout.3. Comparative analysis of the temperature experiment,1-1-18-19,1-1after the roof greenhouse withouttemperature, ground temperature due to individual factors, the number of early greenhouse less than1-1-13;later than1-1-13No. gradually greenhouse. Produce the main reasons for this great relationship with thegreenhouse structure,1-1-13after the high wall2.7m, day light heated area for the entire wall area, and1-1-18,1-1-19No. wall height of4.2m, the length of the greenhouse under the same heat of1.56times thearea of1-1-13, so sunny weather1-1-18,1-1-19temperature rise rapidly. According to the construction shedcost comparison, non-standard greenhouse roof after the cost savings of about8818yuan, plus the absenceof non-greenhouse after the roof after the roof can save columns, purlins, rafters, straw mat, linoleum, feltand related labor and other costs, greatly reduce the construction process, can effectively avoid large-scalecentralized dispatching column greenhouse construction, purlins, rafters, straw mat, linoleum, felt and othermaterials difficult problem.. Combining conclusion4, no conclusions can be drawn after5more forgreenhouse roof Shanshan County agricultural production in the early spring, so that, in the latter part ofagricultural development in large-scale facilities can significantly reduce construction costs, saving a lot ofmoney. From the measured air temperature, ground temperature data can be seen,1-1-19greenhouseshading due to surface factors, straw mat on the shed heat storage, thermal insulation test results moreobvious.
