Intelligent greenhouse system supports transformation and upgrading!

Construction Standards

Greenhouse should be built in a place where transportation is convenient, the terrain is flat and open, the drainage is convenient, there are reservoirs, rivers or groundwater is abundant, the terrain is high and dry, the ground water level is below 0.5 meters, and the soil is deep and fat.

In the construction of greenhouse, attention should be paid to the interval between the two rows of columns in the greenhouse. The interval should be as small as possible, which should be about 80cm. Only an east-west cement ditch and pedestrian road should be built in the middle. The east and west sheds are 0.8-2 meters apart, and there is a small ditch over 800cm wide in the center. The distance between the two sheds in the north and the south is about 3-5 meters, which is used for digging ditches, installing water supply pipelines and building traffic distances. The distance between the two greenhouses should not be less than the width of one greenhouse.

Greenhouse site selection

Regarding the location of greenhouses, soil is an important source of nutrients for crops. Attention should be paid to the content of soil organic matter. It is recommended to regularly test the soil before building greenhouses. If the content of soil organic matter is not enough, it can be supplemented in advance. The cleaning of soil environment is also particularly important in the planting process such as the seedbed stage of the crop planting area.

The orientation of the greenhouse has a great influence on the heat storage capacity in the greenhouse, which is very important for the solar greenhouse. The north-south or slightly southwest orientation is better, that is, the north-south is the length of the greenhouse and the east-west is the width of the shed, which is convenient for heat accumulation.

At the same time, the basic requirements for the construction of greenhouse types should also be considered. For example, the bottom of the foundation in glass greenhouse should generally be more than 0.5 meters lower than the outdoor ground. According to climate and soil conditions, the distance between the top surface of the foundation and the outdoor ground should be more than 0.1 meters. In addition to special requirements, the distance between the top surface of the foundation and the indoor ground should be more than 0.4 meters. The external pressure depth of the film in the film greenhouse, etc.

Covering material

The film covering material is selected as a special plastic film for the construction of facility agricultural production, and its light transmittance, heat preservation, tensile strength and aging resistance are better than ordinary agricultural film.

Glass is divided into ultra-white rolling glass and ordinary transparent glass, the advantage is high light transmittance, can reach about 90%, long service life, fire prevention, corrosion resistance. The difference between ultra-white calendered glass and ordinary glass is that its light enters the room with diffuse reflection and will not cause direct emission to indoor crops. The disadvantage is that the ability to resist hail natural disasters is poor, the construction and installation are cumbersome, and the top waterproof needs to be done well.
