Feasible Analysis on Temperature Environmental of Sunlight Greenhouse and Long-season Cucumber Cultivation in Laoting

Cucumber was cultivated one time every year in sunlight greenhouse of Laoting County from Septemble 2010 to July 2011,the air temperature of indoor and outdoor and 10 cm ground temperature of indoor were mensurated timly in 7:30,12:00 and 17:00 of every day,and cucumber output was counted in every day of harvesting period.Extreme air temperature and extreme ground temperature of whole growth period in sunlight greenhouse were definited,and the air and ground temperature inside and outside greenhouse and the yield were compared in different stage(high temperature stage and low temperature stage)and different weather(cloudy and sunny for several days)conditions to discuss the feasible of long-season cucumber cultivation in sunlight greenhouse of Laoting.The results showed that insulation capability in winter and ventilation cooling capability in spring and summer of sunlight greenhouse were good for cultivating long-season cucummber in Laoting climate.In cucumber production of sunlight greenhouse,increasing the temperature and light of sunlight greenhouse was the important way to improve the yield of cucumber.
