The orientation selection of the green house

It is better to surpass the frozen layer(green house). The greenhouse foundation design is determined according to the geological structure and local climate conditions. The foundation in cold areas and areas with loose soil is relatively deep. Greenhouses that cannot be produced throughout the year should be deeper than those that are produced throughout the year. 2030 cm thick ground beam should be added on the foundation filled with rubble or river stone. The wall should be built on the ground beam. The wall should have thermal insulation interlayer, which is filled with benzene board, perlite and other thermal insulation materials. It is recommended to leave expansion joints if the wall exceeds 70 meters. According to the nature of the greenhouse, a certain ventilation window shall be reserved on the back wall of the greenhouse for ventilation in winter. Before the wall masonry and capping of rainbow greenhouse, the embedded parts of arch frame shall be removed for the installation of arch frame. The height of the greenhouse wall is determined according to the greenhouse span. Generally, it is 8 meters, and the height of the back wall of the greenhouse is 2.5 meters. 7.5m across the back wall of the greenhouse, 2.3m high is appropriate.

The site selection(green house) should be on flat land as far as possible, and the site selection of greenhouse is very important. The groundwater level should not be too high. Avoid light blocking mountains and buildings. For planting and breeding users, sheds can not be built in polluted places. In addition, the wind resistance of the selected greenhouse should be considered in areas with strong monsoon. The wind resistance of general greenhouse shall be above grade 8.

The orientation of the greenhouse has a great impact on the heat storage capacity of the greenhouse, especially for the solar greenhouse. According to experience, it is better for greenhouses in the south to face to the West. The angle to the West should be 510 degrees. This facilitates the greenhouse to store more heat. If multiple greenhouses are built, the spacing between greenhouses shall not be less than the width of one greenhouse.

The orientation of the shed(green house) is that the shed head of the shed is on the north and south sides respectively. It is recommended to choose the north-south orientation for the planting shed. This orientation can distribute the crops in the greenhouse to uniform light.

The wall data of greenhouse can be used as long as it has good thermal insulation and heat storage capacity. The inner wall of the greenhouse stressed here must have heat storage function, and the masonry of the solar greenhouse should be adjusted to local conditions. To store heat. At night, these heat will be released to maintain the temperature balance in the shed. Brick wall, cement plastered wall and earth wall all have heat storage capacity. The wall of greenhouse generally adopts brick concrete structure.
