Plant aeroponic culture control device and method

Abstract

The invention provides a plant aeroponic culture control device and method. The Plant aeroponic culture control device comprises an atomization control box, an aeroponic culture box, image pickup equipment and a computer; the atomization control box is provided with a controller; the aeroponic culture box is connected with the atomization control box; the image pickup equipment is used for acquiring an image of a plant; the computer is respectively connected with the controller and the image pickup equipment; the computer is used for acquiring sectional areas and minimum enclosing rectangle parameters of a leaf crown and a root of a plant according to the image of the plant, acquired by the image pickup equipment, computing the sectional area ratio of the leaf crown to the root and the area ratio of minimum enclosing rectangles and sending a computed result to the controller; and the mist delivery quantity of the atomization control box is controlled by the controller. The plant aeroponic culture atomization control based on a root shoot ratio is particularly suitable for aeroponic culture atomization control leaf vegetables, not only can the traditional aeroponic culture operationbe finished, but also a corresponding regulation strategy can be computed according to the growth condition of the vegetables, the condition that the leaf vegetables are excessively developed in roots and slightly few in leaves in an aeroponic culture process is solved, and the problem of growth vigor of roots and crowns is controlled to a certain extent.

Description

technical field

[0001] The invention belongs to the field of agricultural engineering research, and in particular relates to a plant aeroponics control device and method. Background technique

[0002] Nowadays, soilless cultivation has become one of the important directions of agricultural development, and aeroponics is the most cutting-edge soilless cultivation technology. Compared with hydroponics, it can save a lot of energy and less waste of water and nutrient solution, and can control the spread of diseases; the roots of aeroponic vegetables are suspended in the air and fully contact with the air, which in turn makes the vegetables more healthy. The metabolism and absorption rate of nutrients and water by the roots is greatly improved, maximizing the regenerative physiology of the root system. This brings convenience to the production of root medicine vegetables, but it has no obvious effect on the production of non-root medicine crops. Compared with hydroponics, there...
