Automatic control device for plant growth environment

Abstract

The invention discloses an automatic control device for a plant growth environment. The automatic control device comprises a mixing chamber, a growth chamber and a clean air feeder which is connected with the mixing chamber; the bottom part of the mixing chamber is provided with two circulating fans; a first fan is used for eliminating exhaust gas in the mixing chamber and performing thermoregulating and conditioning on air in the mixing chamber; a second fan is used for air current circulation between the mixing chamber and the growth chamber; a plurality of cultivating racks are arranged in the growth chamber; each cultivating rack is divided into multiple layers; each layer is provided with drainage channel and a certain number of LED (light emitting diode) lamps; the drainage channels are connected with a water supply and drainage system and a nutrient solution supply system; growth environment parameter acquisition sensors are also arranged in the growth chamber; data acquired by each sensor are transmitted to a controller through the Internet of Things; various parameters of the plant growth environment are adjusted by the controller according to growth environment curves of plants in different periods; the controller is connected to a man-machine operation interface. According to the automatic control device disclosed by the invention, the seedling and growth cycles of crops can be greatly shortened, the land use rate is increased, and output per unit area is increased.

Description

technical field [0001] The invention relates to an automatic control device for plant growth environment. Background technique [0002] At present, my country's agricultural technology is relatively backward, land resources are scarce, water resources are increasingly scarce, farmland is not fully irrigated, farmland is too scattered, agricultural resources are scarce, and the degree of automation is low. It was even left unused or even abandoned. Although my country's agricultural development has also made great achievements, it is also facing huge challenges: [0003] Lack of agricultural resources and serious pollution: China's agricultural development currently mainly relies on resources such as land, water, and crops. Although the total amount of resources ranks among the top in the world, the per capita share is far below the world level. In addition, the excessive exploitation of groundwater And large-scale flood irrigation of farmland, water resources are becoming i...
