摘要 研究了秋冬季节黄瓜生产温室中不同部位土壤温度和空气温湿度的变化规律。结果表明,南部土壤和空气温度变化最小,较适宜黄瓜生长,中部土壤和空气温度变化幅度相对较大;不同时期,不同部位温湿度变化情况不同;长时间低于0℃的空气温度(9 h)以及低于10℃的土壤温度(8.5 h)是导致温室北部黄瓜植株死亡的直接原因;随时间推移,温室每天处于饱和空气湿度的时间逐渐增多,温室中部湿度最大,北部次之,南部最小。 The soil temperature and air temperature and humidity changes in a greenhouse during cucumber cultivation in autumn and winter were studied. The results indicated that the soil and air temperatures varied least in the south of greenhouse(where cucumber grew relatively well) while com- paratively greatly in the central part. The temperature and humidity were various in the different parts of greenhouse and changed with time. The direct factors that led the cucumber plants in the north of greenhouse to die were that the air temperature was below 0 ℃ for long time(9 h) and the soil temper- ature below 10℃ quite long(8.5 h). The daily duration for the air in greenhouse to be at saturated hu- midity gradually increased with the passage of time, and the air humidity of greenhouse was the grea- test in the central part, next in the north, and the least in the south.
