从气象角度入手,对地处黄土高原半干旱雨养农业区的日光温室小气候状况进行监测分析,得出室内不同高度((1. 5, 1. 0,0. 5 m)的温、湿度有所差异:高层1. 5  m温度相对较高而湿度较小,反之,低层0.5 m温度较低而湿度较大,这样,在高层形成了高温低湿的微环境,而在低层形成了低温高湿的微环境。黄瓜整个生育期,温室内日温度维持在12~23. 5   C左右,低层相对湿度都在77. 3%以上。另外,病害调查结果显示:从苗期开始就有黄瓜霜霉病的发生,一直到结瓜期都较严重,且植株下层的发病程度高于上层。因此,得出霜霉病发生发展的适宜气象条件:低温(12~23.5  C)高湿(>83%)有利于其发生最后提出适合该地区温室的病害综合防治措施。

 An observation and analysis on microclimate in greenhouse were carried out in semi一arid region which lies in Loess
Plateau.  "hhc results show that the temperature and the relative humidity in different height in greenhouses were different, that
is to say, the temperature at 1.5 m height was higher than that at() .> m,and the relative humidity at 1.5 m height was lower
than  that  at() .> m,thus, there was a microcnvironment of the lower temperature and higher RH at() .5 m height compared
with that at 1. 5 m.   IW  ring cucumbers growth period,the temperature in greenhouses maintained around 12一23. 5  C,R H ex-
cccdcd 77. 3%in lower layer.  Additionally, the survey shows that downy mildew occurred in every growth stage from seeding
to bearing period,and the degree of disease in under part of the plant was more serious.  So the conclusion on optimum climate
condition of occurring and spreading of disease was the lower temperature and higher RH.  At last, we brought forward the in-
tegrated control measure.

Key words: climate condition, control measure, greenhouse, cucumber downy mildew
