Facility agriculture depends on greenhouses, these highly intelligent greenhouses have you seen?

Facility agriculture is a modern agricultural method that uses engineering technology to produce plants and animals efficiently under relatively controllable environment. Facility agriculture includes facility planting, facility breeding and facility edible fungi.

In China, more than 90% of facility agriculture projects are covered by polyolefin greenhouse film. Today, I collected a variety of greenhouses for you to see which is best to use!

Large span asymmetric water control thermal insulation greenhouse

According to the principle of daylighting and heat storage in solar greenhouse, the greenhouses scientifically utilize the southern daylighting, the northern heat storage and the principle of heat preservation and heat insulation to improve the heat storage capacity and temperature of ordinary greenhouses. At the same time, the heating tank is designed in the north of the greenhouse to control the fermentation and heat release of brewing heat by means of water replenishment, so as to realize the ability of heating according to the heat requirements of the greenhouse.

Compared with ordinary solar greenhouse, the land utilization rate is increased to 80%, the construction cost is reduced by more than 40%, and the greenhouse has a large span, which is conducive to mechanization.

Sliding cover type modern energy-saving solar greenhouse

The new solar greenhouse changes the traditional structure of "three walls and one slope, insulation by + rolling curtain machine" in China, solves the problem of poor rain, snow, wind and fire resistance of traditional solar greenhouse, integrates the advantages of uniform light and temperature distribution of large multi-storey greenhouse and good thermal insulation and heat storage performance of traditional solar greenhouse, and realizes the automatic control of solar greenhouse.

By adopting the prefabricated arched circular light steel frame and the innovative structure of moving thermal insulation gable, the overall lighting rate of the greenhouse is increased by more than 10%. Using active solar water circulation and shallow soil heat storage bear system, the overall solar heat storage performance of the greenhouse is increased by more than 2 times. The rock wool color steel sheet hard insulation covering and its mechanical operation system are developed. The overall insulation efficiency of the greenhouse is increased by about 3 times, and the accurate operation and automatic control of the thermal insulation covering of the solar greenhouse are realized. The new greenhouse ridge height is moved forward, the rear shade is reduced, the distance between the front and back greenhouse is narrowed, and the land utilization rate is about 20%.

Facilities agriculture efficient fertilizer irrigation intelligent greenhouses

The system does not need manual intervention, using temperature and humidity sensor to measure the temperature and humidity difference at different heights, using the energy balance method to calculate the evapotranspiration of crops, and convert the evapotranspiration into the irrigation amount, through the single chip microcomputer to set the program to control the switching time of the solenoid valve, that is, to control the irrigation amount.

The use of Venturi type fertilizer injection pump for fertilizer irrigation can greatly improve the utilization rate of fertilizer. Based on the flow and time of irrigation, the amount of fertilizer used per tree or per unit area can be accurately calculated.

New smart greenhouse

The most advanced biosimulation technology is used to simulate the most suitable environment for the growth of plants in the shed. Temperature, humidity, CO2, illuminance sensors are used to sense the environmental indicators of the greenhouse, and the data is analyzed by the microcomputer, which monitors the water curtain, fan, sunshade and other facilities in the shed, so as to change the biological growth environment inside the greenhouse.
