宁夏NKWS-Ⅲ型日光温室设计建造及冬季温光环境特征

Ningxia NKWS-Ⅲ Solar Greenhouse Design-building and Temperature and Light Environmental Characteristics in Winter

为优化日光温室结构设计和促进温室大型化发展,设计建造了宁夏NKWS-Ⅲ型日光温室,并于2008年冬季罕见低温条件下运行测试。结果表明:NKWS-Ⅲ型日光温室具有透光率高,容积大的特点,有利于无限生长型蔬菜长季节栽培管理,在一般天气条件下,可基本保证茄果类蔬菜度过冬季。但是当冬季室外每日辐射总量低于7.82 JM/m2、最低温度下降至-14.7℃、日平均温度低于-8.8℃时,利用NKWS-Ⅲ型日光温室进行茄果类蔬菜越冬生产时需添加增温设备进行加温,适时做好维护结构的保温措施。

In order to optimize structure design and promote maximization development of solar greenhouse,the Ningxia NKWS-Ⅲ solar greenhouse was designed,built and tested under rare low temperature condition in 2008 winter.The results showed that NKWS-Ⅲ solar greenhouse had feature of high transmittance and big volume which was helpful to administration of infinite growth-type vegetable under long seasonal cultivation.In the general weather conditions,this type solar greenhouse can basic ensure eggplant vegetable to get through winter.But it needed to taking well insulation measures and adding warming equipment when encountered limit low temperature condition.The results of statistical analysis indicated that could seen as outside environment critical exponent for warming of Ningxia NKWS-Ⅲ solar greenhouse when the daily total radiation was 7.82 JM/m^2、the lowest temperature was-14.66℃、daily average temperature was-8.79℃.
