談到冬季取暖，首先要討論溫室的保溫問題。溫室保溫效果差，采暖成本高。因此，氣密性差的溫室一定保溫性差。由于我國南北溫差大，傳統(tǒng)上對溫室建設(shè)的要求也不盡相同。
南方和北方在設(shè)計和建造溫室時都要考慮溫室的氣密性，這樣才能保證降低采暖成本，提高花卉質(zhì)量。
有幾種方法可以改善溫室的氣密性
在單拱棚、節(jié)能日光溫室、多跨膜溫室的設(shè)計和施工中，應(yīng)注意在防蟲網(wǎng)的兩端加保溫膜，并將裙膜埋入土中，以達到保溫節(jié)能的功能。
對于多跨薄膜溫室，其四周宜砌30-50cm的磚墻，這樣可以起到很好的保溫作用。另外，多跨膜溫室的端部和側(cè)面應(yīng)固定牢固，密封嚴密，防止進氣。
如果是多跨玻璃溫室和多跨PC太陽能電池板溫室，一方面周圍要砌50至100cm的磚墻，另一方面要注意屋脊接縫、端罐接縫、端面頂縫、側(cè)面頂縫等，必須用膠水封住。
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.
