谈到冬季取暖，首先要讨论温室的保温问题。温室保温效果差，采暖成本高。因此，气密性差的温室一定保温性差。由于我国南北温差大，传统上对温室建设的要求也不尽相同。
南方和北方在设计和建造温室时都要考虑温室的气密性，这样才能保证降低采暖成本，提高花卉质量。
有几种方法可以改善温室的气密性
在单拱棚、节能日光温室、多跨膜温室的设计和施工中，应注意在防虫网的两端加保温膜，并将裙膜埋入土中，以达到保温节能的功能。
对于多跨薄膜温室，其四周宜砌30-50cm的砖墙，这样可以起到很好的保温作用。另外，多跨膜温室的端部和侧面应固定牢固，密封严密，防止进气。
如果是多跨玻璃温室和多跨PC太阳能电池板温室，一方面周围要砌50至100cm的砖墙，另一方面要注意屋脊接缝、端罐接缝、端面顶缝、侧面顶缝等，必须用胶水封住。
When it comes to heating in winter,we must first discuss the heat preservation of greenhouse.The effect of heat preservation in greenhouse is poor,and the heating cost must be high.Therefore,the greenhouse with poor air tightness must have bad heat preservation.Due to the great difference of temperature between North and South in China,the requirements of greenhouse construction are also different in tradition.
Both the South and the North should consider the air tightness of the greenhouse when designing and building the greenhouse,which can ensure that the heating cost can be reduced and the quality of flowers can be improved.
There are several ways to improve the air tightness of greenhouse
In the design and construction of single arch shed,energy-saving solar greenhouse and multi span film greenhouse,attention should be paid to adding thermal insulation film at both ends of insect proof net,and the skirt film should be buried in the soil,so as to achieve the function of heat preservation and energy saving.
For multi span film greenhouse,it is better to build 30-50 cm brick wall around,which can play a good role in heat preservation.In addition,the end and side of the multi span film greenhouse should be fixed firmly and tightly sealed to prevent air intake.
If it is a multi span glass greenhouse and a multi span PC solar panel greenhouse,on the one hand,a 50 to 100 cm brick wall should be built around,on the other hand,attention should be paid to the roof ridge joint,the joint of the end tank,the top joint of the end face,the top joint of the side,and so on,which must be sealed with glue.
