摘  要:
对2006~2008年冬季(12月至翌年2月)喀左县日光温室大棚最低气温观测资料进行统计分析。结果表明:冬季棚内平均最低气温为8.1℃,极端最低气温为3.5℃。大棚最低气温随大气最低气温的升降而相应升降;随着云量的增加,次日棚内外最低气温差值呈逐渐减小的趋势;次日棚内最低气温升降与风向也密切相关。利用回归分析方法得出了冬季温室大棚内最低气温的预报模型,准确率达到83%,取得了较好的服务效果。

摘  要:
The minmum air temperature of sunlight greenhouse in winter from 2006 to 2008(from November to February)in Kazuo county was analyzed.The results indicated that the mean minimum air temperature of sunlight greenhouse was 8.1℃ in winter,and the extreme minimum air temperature was 3.5℃.The minimum air temperature of sunlight greenhouse increased with the increase of air temperature.The difference of minimum air temperature inside and outside sunlight greenhouse the next day decreased with the increase of colund cover.The minimum air temperature inside sunlight greenhouse the next day was telated with the wind direction.Prediction model on the minimum air temperature of sunlight greenhouse in winter was developed by regression analysis method.The accuracy rate reached 83% and achieved the better service.
