德州市蔬菜生产型日光温室优化设计

摘要

针对德州市目前日光温室应用中普遍存在的结构不合理、建造技术落后、生产性能较差等问题，在理论设计的基础上，立足德州，本着科学合理、尊重实际、易于建造、成本经济、便于管理的原则对德州市蔬菜生产型日光温室进行了优化设计。通过对日光温室墙体材料、后屋面材料、前屋面支撑及骨架材料、覆盖材料等的合理选择，以及对日光温室长度、净宽度、屋脊和后墙高度、墙厚度、后屋面仰角、前屋面角、下挖深度的优化设计，使日光温室的温度环境得到较大改善，最低气温和最低地温分别提高35．0％～237．5％和21．4％～142．9％，保证了温室内蔬菜生产的正常进行。%Aiming at the problems of unreasonable structure,outdated building technology and poor pro-ductivity of greenhouse in Dezhou City,the optimal design of vegetable greenhouse was carried out based on the theoretical design and Dezhou status,and according to the principles of scientific and reasonable,respect-ing facts,easy to build,low cost and easy to manage.The wall,back -roof materials,supporting and frame-work materials before the roof and cover materials were chosen reasonably.The length,net width,height of ridge and back -wall,wall thickness,angle of elevation of back -roof,angle before the roof,and digging depth of greenhouse were optimized.Then,the temperature environment status closely related to productivity of greenhouse was improved greatly,and the lowest air temperature and soil temperature increased by 35.0% ~237.5% and 21 .4% ~1 42.9% respectively,which could assure normal vegetable production in greenhouse.
