尽量降低棚内温度夏季温度很高,棚内温度甚至在40℃以上。此时,在加强通风的基础上,还应采取遮光、喷水等措施,降低棚内温度。有的菜农在棚室中安装了喷灌系统,在大棚骨架的中央大约每隔5米有一个喷头,喷头上的挡板受到水的冲击不断摆动,使得棚室中每个位置都能喷到水,这种叶面喷水的方式对于棚室降温十分有效。若安装这种专业喷灌设施成本较高,菜农也可将冬季浇水用的微灌设施安装上,不过要保证小孔朝上,水流向外喷出,也能起到
As far as possible to reduce the greenhouse temperature Summer high temperature, greenhouse temperatures even above 40 ℃. At this point, on the basis of strengthening ventilation, shading, water spraying and other measures should also be taken to reduce the temperature inside the shed. Some farmers installed sprinkler irrigation system in the shed, and there was a sprinkler about every 5 meters in the center of the scaffolding. The baffle on the sprinkler was swung by the impact of water, so that every position in the shed could be sprayed with water , This foliar spray way is very effective for greenhouse cooling. If the installation of such a professional sprinkler irrigation facilities higher costs, farmers can also be used in winter irrigation with micro-irrigation facilities installed, but to ensure that the holes up, the water jet out, but also play
