Investigation and analysis of main technical problems during construction of solar greenhouse in South Xinjiang by Xinjiang Production and Construction Corps

Abstract: South Xinjiang, which has good light and heat resources, is the main region for developing solar greenhouse and making structural adjustments and transforming the development pattern of modern agriculture in Xinjiang. However, the solar greenhouses in South Xinjiang are largely introduced from other places in China, and do not have strong adaptability and pertinence and have many technical problems, especially in terms of constructive techniques, which should be studied and summarized in order to avoid emerging new problems with the rapid development of solar greenhouse. The solar greenhouse programs containing more than 50 greenhouses selected from more than 40 farms of 4 divisions in Xinjiang Production and Construction Corps have been used to make an investigation. The effects of environmental control and production under the different modes of construction are compared, and the targeted research and measurement are made for the relevant construction parameters and technical measures. We have found that there are some serious, common problems in the overall style design, the structural arrangement, the component design as well as in the structure of building envelope, such as small south roof angle and big deformation in structure, which have caused the constructive cost waste and functional defect in solar greenhouse. It is necessary for the solar greenhouse in South Xinjiang to make an improvement in research and development and extension of constructive techniques, overall parameter determination, north wall design, skeleton layout, and north roof arrangement, as well as make a careful and scientific evaluation when introducing new type of solar greenhouse. The problems sorted out by this article are also common in North China and very typical and of great representativeness. To consummate the performance index system of the solar greenhouse in South Xinjiang, and reveal the technical research direction and focus, have a strong guiding role in the construction of the solar greenhouse in Xinjiang and even in North China.
