后屋面对日光温室温度变化的影响
The Influence of Back Roof on Greenhouse Temperature
摘要
Abstract
[ Objective ] The purpose of this project was to explore the impact of the back roof on the greenhouse temperature so that a theoretical basis could be provided. [ Method ] The greenhouses with or without back roofs were taken as the study objects, and the changes of their ground and air temperature data were compared and studied in the coldest phase in deep winter. [ Result ] The results from our experiments showed that the ground and air temperature in 1 - 1 - 18 and 1 - 1 - 19 greenhouses that have no back roofs is lower than that in 1 - 1 -13 greenhouse in the early period and in later period gradually surpasses the 1 -1 -13th greenhouse. This happens mainly because the temperature is closely related to the greenhouse structure. 1 - 1 - 13 greenhouse fe back wall is as high as 2. 7 m and the daylight heating area is as large as the whole wall area, but 1 -1 -18, 1 -1 -19 greenhouses'walls are 4.2 m high. Under the same greenhouse length the heating area is 1. 56 times higher than that in the 1 - 1 - 13 greenhouse, therefore in the cloudless day weather, temperature in 1 -1 -18, 1 -1 -19 rises quickly. [ Conclusion] According to comparative trial analysis of the awning funds and temperature, greenhouses without back roofs adapt well to the area in the south of mountains in Shanshan County. So it follows that greenhouses built in this way can greatly reduce the construction cost greatly in later period's large - scale facility agricultural development, thus saving a large amount of funds.关键词
