Abstract

The invention relates to the field of facility cultivation, and particularly provides a plant factory vertical-horizontal tube ventilation method. The plant factory vertical-horizontal tube ventilation method comprises the steps that ventilation tubes are formed for vertical tubes perpendicular to ground and a plurality of horizontal tubes horizontally installed on the vertical tubes; the verticaltubes are hollow and cavities are formed in the vertical tubes, one ends of the cavities are closed, and the other end of the cavities are open as air inlets; the horizontal tubes are hollow, and thecavities of the horizontal tubes are connected to the cavities of the vertical tubes; the horizontal tubes are provided with a plurality of air outlets at equal distances, and the air outlets face plant cultivation layers of a cultivation shelf; and when ventilating is carried out, airflow enters the cavities of the horizontal tubes from the air inlets through the cavities of the vertical tubes and is blown out from the air outlets in the horizontal tubes into the plant cultivation layers of the cultivation shelf. The invention also provides a corresponding ventilation device. The invention further provides a corresponding ventilation device, and the plant factory vertical-horizontal tube ventilation device can adopt a system circulation ventilation mode or a self-circulation ventilationmode. The plant factory vertical-horizontal tube ventilation method and device are simple in structure and low in cost, the horizontal tube air outlets penetrating through the entire layers of the cultivation shelf ensure uniform ventilation, the diameter of the vertical tubes is small, the occupied area is small, and the plant factory vertical-horizontal tube ventilation method and device are suitable for mass promotion.

Description

technical field [0001] The invention relates to the field of facility cultivation, in particular to a plant factory vertical-horizontal tube ventilation method and a device thereof. Background technique [0002] The ambient temperature, humidity and airflow velocity of the plant factory are mainly obtained through the heating and cooling air conditioning circulation ventilation system. Due to the unreasonable layout of the air inlet and outlet of the plant factory, especially the large number of layers of cultivation frames, the distance between plant cultivation layers is short (about 250mm), and the ventilation is difficult, resulting in the formation of airflow around the cultivation frames. In addition, there is an artificial light source installed on the top of the plant cultivation layer, which generates a lot of heat. In the case of poor ventilation, the microclimate conditions for plant growth between the plant cultivation layers of the cultivation frame, such as the...
