- 摘要:
- 为探索适宜宁夏沙漠非耕地建造的日光温室结构，对现有日光温室进行结构创新，构建了双拱架内置保温被结构，对优化及对照温室内空气温度、空气湿度、露点温度、土壤10 cm处温度及光照强度等指标进行测试分析，得出了优化温室结构优势性。结果表明：优化温室较普通结构温室可有效提高空气温度2.48 ℃，降低相对湿度7.52%，提高露点温度1.96 ℃，提高土壤温度2.03 ℃。优化温室月均透光率为56.70%，较对照温室低13.55%。优化温室可有效提高室内空气温度和土壤温度，有效保障0 ℃以上的露点温度，避免作物发生冻害，实现作物在沙漠非耕地安全越冬生产。
- Abstract:
- In order to explore the appropriate structure of sunlight greenhouse in Ningxia non-cultivated desert land，innovated the structure of existing greenhouse，which was a structure of builted-in thermal insulation in double arch and then analysed the index difference which contained air temperature，air humidity，dew point temperature，10 cm soil temperature and light intensity between the optimized greenhouse and the control greenhouse，to get the structure advantages of the optimized greenhouse.The results showed that the optimized greenhouse could effectively improve the air temperature of 2.48 ℃，reduce the relative humidity of 7.52%，and improve dew point temperature of 1.96 ℃ and the soil temperature of 2.03 ℃.The average transmittance of the optimized greenhouse was 56.70%，which was 13.55% lower than the ordinary greenhouse.The optimized greenhouse could effectively improve the indoor air temperature and soil temperature，effective keep the dew point temperature above 0 ℃，which could avoid the crops of occurrence frost damage，to realize crop production in winter of non cultivated land in the desert.
