我们于1989年初与辽宁省熊岳农专协作研究利用银色聚脂镀铝膜为冬春季温室黄瓜生产增益(增温、增光、增产)。经过春冬的研究,取得了较好的效果。为便于使这项技术在各地区得到广泛应用,我们将试验情况及分析报告如下。一、通辽地区气候概况及保护地结构通辽市位于东经122°32′,北纬43°44′,年平均温度5.8℃,极值低温为-34.9℃,一般年极值低温都在-30℃以下。2月份平均日最低温度-13.9℃,极值低温为-20.5℃,所以日光温室一般有两种定植期:一种是2月
In early 1989, we cooperated with Xiong Yue Agricultural College in Liaoning Province to study the production gain (temperature increase, increase light, increase production) of cucumber in the greenhouse in winter and spring by using the silver polyester aluminum plating film. After spring and winter studies, achieved good results. In order to facilitate the wide application of this technology in various regions, we will test the situation and analysis report as follows. I. Overview of Tongliao and Climatic Structure Tongliao City is located at 122 ° 32’E and 43 ° 44’N, with an annual average temperature of 5.8 ° C and an extreme low temperature of -34.9 ° C. The annual average extreme low temperature is below -30 ° C . In February the average daily minimum temperature of -13.9 ℃, the extreme low temperature of -20.5 ℃, so there are generally two kinds of greenhouse greenhouse planting: one is February
