Abstract

Passive solar greenhouses are developing rapidly in China and they can significantly increase crop yields. The main reason for this increase in crop yield is the availability of a suitable thermal environment. In order to investigate the thermal environment of the heliostats in the high latitude water-scarce and cold region of Shanxi, the thermal environment of the heliostats in this region was measured in this paper, and the results showed that the highest temperature of the heliostats was located in the eastern part of the crop area at about 4m from the back wall; the highest and lowest temperatures of the heliostats were located in the eastern part of the crop area;the maximum and minimum temperatures in the greenhouse were located in the eastern part of the crop area, and the temperatures in most of the crop area exceeded 30°C. This research can provide theoretical support for the construction and management of solar greenhouses in low heat and water areas at high latitudes.

Abstract in Chinese

中国被动式日光温室发展迅速，被动式日光温室能够大幅提高作物产量。可实现作物增加的主要原因是可以提供适宜的热环境，为探究山西高纬缺水寒冷地区的日光温室热环境，本文对该地区日光温室热环境进行测定，其结果显示：该日光温室最高温在作物区东部距离后墙4米左右的位置；温室的最高温和最低温都位于作物区的东部,且作物区大部分的区域的温度都超过了30℃。该研究可为高纬低热少水地区的日光温室建造和管理提供理论支撑。
