Greenhouse canopy environment control system and method based on drip irrigation pipe network

Abstract

The invention discloses a greenhouse canopy environment control system and method based on a drip irrigation pipe network. The greenhouse canopy environment control system comprises head devices and a pipe network, wherein each head device comprises a pressure hot air device, a pressure CO2 air source device, a ventilation and air-exchange device and a drip irrigation fertilizing device; and the pipe network comprises a water pipe, a branch pipe, a capillary pipe and a drip irrigation emitter. By switching the different head devices, operation such as greenhouse canopy temperature regulation,CO2 fertilization, ventilation, air exchange, cooling, dehumidification, drip irrigation fertilization and the like can be realized. In the invention, the greenhouse canopy environment is controlled by the drip irrigation pipe network, the control space is reduced into the crop canopy from the entire greenhouse space, and meanwhile, the uniformity is also greatly improved, thereby greatly reducing the energy consumption for greenhouse environment control, lowering the investment on control equipment, providing a uniform and appropriate environment for the growth of crops, and improving the production capacity and quality of the crops.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture, and relates to a facility agriculture environment control system and method, in particular to a greenhouse canopy environment control system and method based on a drip irrigation pipe network. Background technique [0002] Greenhouse environmental control is to use engineering technology to control the temperature, humidity, light, CO 2 The concentration is adjusted and controlled to provide a suitable growth environment for crops. The control technology and application effect of the greenhouse environment largely determine the success or failure of facility agricultural production and the level of production efficiency, while the temperature regulation of traditional greenhouses, CO 2 Greenhouse environment control technologies such as fertilization, ventilation, ventilation, cooling, and dehumidification are carried out in the entire greenhouse space, and the environmental paramet...

Problems solved by technology

The control technology and application effect of the greenhouse environment largely determine the success or failure of facility agricultural production and the level of production efficiency, while the temperature regulation of traditional greenhouses, CO 2 Greenhouse environment control technologies such as fertilization, ventilation, ventilation, cooling, and dehumidification are carried out in the entire greenhouse space, and the environmental parameters of the entire greenhouse space are controlled within the set ideal range. Due to the large control space, energy consumption and operation The cost is high, and the uniformity of regulation is difficult to guarantee
