通过春季降雨、扬沙、沙尘暴等天气变化过程,研究外界环境对温室内外光照强度、相对湿度、气温、地温等环境因子的影响。结果表明:春季各种灾害天气对温室内外环境因子产生显著影响。降雨、扬沙、沙尘暴等天气显著降低温室内外光照强度、空气温度和土壤温度;降雨增加温室内外相对湿度;扬沙降低温室外相对湿度,增加温室内相对温度;温室内气温降低幅度大,而温室外温度降低程度较小。不同天气变化过程温室内外环境因子变化不一致。温室外光照强度高于温室内,温室内相对湿度、气温、土壤温度均高于温室外,存在明显的相关性。风沙天气应拉紧压膜线、清除尘土、人工补光,改善温室内光照条件。
The effects of external environment on environmental factors such as light intensity, relative humidity, air temperature and ground temperature inside and outside the greenhouse were studied through the process of weather changes such as spring rainfall, sand blowing and dust storms. The results show that all kinds of disastrous weather in spring have a significant impact on the environmental factors inside and outside the greenhouse. Rainfall, sand blowing, sandstorms and other weather significantly reduce the light intensity inside and outside the greenhouse, air temperature and soil temperature; rainfall increases the relative humidity inside and outside the greenhouse; sand reducing the relative humidity outside the greenhouse to increase the relative humidity in the greenhouse; The temperature outside the greenhouse decreases to a lesser extent. The changes of environmental factors inside and outside greenhouse under different weather changes are inconsistent. The light intensity outside the greenhouse was higher than that inside the greenhouse, and the relative humidity, temperature and soil temperature in the greenhouse were higher than those outside the greenhouse, and there was obvious correlation. Wind and sand weather should be tensioned film line, remove dust, artificial fill light, improve the greenhouse light conditions.
