A valve V208 is installed on the main passage between the heater 203, the filter 204 and the dehumidifier 205 and the upstream of the fan 201, and valves VI209, VII210 and VIII211 are installed on the branch between the dehumidifier 205, the filter 204 and the heater 203 and the aerosol circuit 305 respectively; the mist machine 202 and the aerosol main pipeline 301 are installed in parallel downstream of the fan 201, and a valve IX212 is installed on the connecting pipeline of the mist machine 202. The opening and closing of the valve is controlled by the sensor control system 4.

[0033] like Figure 4As shown, the transport pipeline 3 is composed of an aerosol main line 301, a cultivation rack pipeline 302, an aerosol outlet 303, a sub-membrane drip irrigation pipe 304 and an aerosol loop 305.

Figure 6 The inclined four-way connection shown in the figure allows the hanging crops to be tied to the raised part of the mist outlet 303 by the traction rope 7, so as to support the hanging crops (including tomatoes, cucumbers, etc.). The end of the sub-membrane drip irrigation pipe 304 goes deep into the cultivation trough 6, which can transport water and fertilizer to the roots of the crops, effectively reducing evaporation and infiltration losses. Figure 1 , 4 It is only used to illustrate the positional relationship between the crops and the greenhouse beams. In fact, the greenhouse beams 5 are located in the horizontal plane, and the crops are arranged along the vertical plane of the greenhouse beams 5.

[0034] The working principle of the utility model greenhouse environment control and field management integrated system is:

[0035] When the crop needs to be fertilized, open valve I105 and valve III107, and close valve II106. The centrifugal pump 102 draws nutrient solution from the nutrient solution storage tank 101 and transports it to the sub-film drip irrigation pipe 304 through the irrigation pipeline 103, thereby realizing drip irrigation and fertilization of the crop under the film; when watering the crop, open valve II106 and valve III107, and close valve I105. The centrifugal pump 102 draws water from the irrigation water pipe 104 and transports it to the sub-film drip irrigation pipe 304 through the irrigation pipeline 103, thereby realizing drip irrigation of the crop under the film.

[0036] When applying pesticides, open valve IV207 and valve IX212, and the fan 201 and the mist machine 202 start to operate. The generated liquid droplets are transported by the airflow from the mist outlet 303 of the cultivation rack pipeline 302 directly to the inside of the crop canopy. At the same time, the airflow will also disturb the crop canopy, increase the penetration of the droplets, and improve the effect of pesticide application.

[0037] After the application of pesticides is completed, the mist machine 202 and valve IX212 are closed, valves IV207, V208 and VII210 are opened, and the fan 201 is operated in reverse to draw the air containing suspended droplets in the greenhouse through the aerosol circuit 305 to the filter 204 for filtration to remove suspended pesticides, purify the air in the greenhouse, reduce the humidity in the greenhouse, and prevent pesticides from harming people.

[0038] When the greenhouse temperature is too low, open valve V208 and valve VI209, start fan 201 and heater 203, and the cold air in the greenhouse is heated by heater 203 and directly delivered to the crop canopy to achieve rapid warming and prevent frost damage; when the greenhouse temperature is too high, open valve IV207, start fan 201, and use outdoor cold air to directly cool the canopy.

[0039] When the humidity in the greenhouse is too high but the outdoor temperature is too low to allow direct ventilation, open valve V208 and valve VIII211, start fan 201 and dehumidifier 205, and the humid air in the greenhouse is dehumidified by dehumidifier 205 and then sent back to the greenhouse, thereby reducing the humidity in the greenhouse and reducing the occurrence of diseases.

[0040] When the flowers of the planted hanging vine crops (such as tomatoes) are in full bloom, valves V208, VI209 and VIII211 are opened, and the fan 201, heater 203 and dehumidifier 205 are started to generate dry and warm disturbed airflow, which causes wind-induced vibration pollination of the crops and improves the fruit setting rate.

[0041] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
