戈壁沙漠区日光温室复合墙体结构参数优化及传热机理的研究

With rapid development of Xinjiang facility agriculture, coming with a large proportion of sunlight greenhouse in agricultural production facilities, and it has set up a showing good economic and ecological benefits. With the widely cultivated in sunlight greenhouse, palisade structure of wall body material and structure become multifarious. In fact, brick wall greenhouses cost more, thermal instability, countries limit the use of clay brick, most greenhouse cob wall collapsed, and unreliable heat preservation and so on, the problems of them need to As soon as possible to solve all. How to fulfill the cultivation demand, it needs to become an important research topic. This project used mortar block add filler material composite wall as the research object, and applied 3D3S and SAP2000 finite element structure analysis program to analyze the mechanics of the composite materials wall.The RGWSRHJ simulation software was used to calculate the change of temperature field of composite wall, it has been proven the mechanism of rice and wheat shell mortar block add filler material wall heat transfer of the greenhouse to determine the reasonable composite wall structure parameters and heat transfer model. Through the analysis of the experimental tests on wall thermal structure and vegetable cultivation, it is necessary to establish the reasonable model of sunlight greenhouse composite wall located in the Gobi desert area so as to provide technical and theoretical support to the high-efficient development of Xinjiang facilities agriculture.

新疆设施农业发展迅速，日光温室在农业生产设施中占80%的比例，并显现出良好的经济和生态效益。随着温室的广泛种植，围护结构中墙体的材料和结构五花八门、多数保温蓄热性能不佳，砖墙温室造价较高、国家限制粘土砖的使用；土墙温室多数墙体坍塌、保温性不可靠等，如何发挥日光温室墙体的蓄热和保温性能，满足温室栽培需求，成为需要研究的重要课题。本项目以砂浆砌块+填充材料复合墙体为研究对象，采用3D3S和SAP2000有限元结构分析程序对复合材料墙体进行力学分析，应用RGWSRHJ模拟软件计算复合墙体的温度场变化，探明稻麦壳砂浆砌块+填充材料墙体温室的传热机理，确定合理的复合墙体结构工艺参数和传热模型；通过复合墙体结构热工特性的试验分析和果蔬栽培的实验测试，制定合理的戈壁沙漠区日光温室复合材料墙体建造模式，为新疆设施农业高产高效稳定发展提供技术和理论支撑。
