摘要
观察了冬季日光温室光照和温度条件对黄瓜茎叶生长的影响。结果表明:光辐射量、见光时段小时积温、日均积温及20 cm地温能有效反映黄瓜茎叶生长的动态变化。光辐射量是影响冬季日光温室黄瓜生长的主要因素,而见光时段小时积温对黄瓜茎叶生长有更为直观的影响。冬季连阴几天放晴后,黄瓜植株的生长有一定的滞后期,与10~20 cm的土壤温度回升慢有直接的关系。
The effects of temperature and light on growth of cucumber in greenhouse in winter were studied in this paper. The results showed that solar radiant energy, accumulative temperature in lighting time calculated growth of cucumber in greenhouse in winter, and the accumulative temperature in lighting time calculated by hour had more directly influence on growth of cucumber. The growth of cucumber had a lag phase after serial cloudy and rainy days, which had directly relationship with the rising temperature of 10 ~ 20 - cm soil layer.
