在日光温室中,一般无人工加温设施,当遇天气突变、寒潮袭击,极易遭受低温冷害。综合几年实践经验,提出如下防低温冷害补救措施。一、加温措施 (1)当外界大幅度降温,室内保证不了蔬菜需要的最低温度时,临时利用柴草或煤燃烧,通过炉灶、烟道散热提高室温。(2)利用工厂(如石油厂、热电厂、化工厂、酿酒厂、造纸厂、冶炼厂等)排出的热水或蒸气作温
In the greenhouse, the general artificial heating facilities, in case of sudden weather changes, cold wave attacks, vulnerable to cold damage. Based on a few years’ practical experience, the following remedial measures against cold damage are proposed. First, heating measures (1) When the outside world significantly cooling, the indoor can not guarantee the minimum temperature of vegetables, the temporary use of firewood or coal combustion through the stove, flue heat to improve room temperature. (2) Using hot water or steam discharged from factories (such as petroleum plants, thermal power plants, chemical plants, breweries, paper mills, smelters, etc.)
