Multisectional Climate Chamber for Accelerated Production of Cultural Plants Under Controlled Parameters

Abstract

The analysis of existing technical means for growing plants in controlled conditions of artificial climate is given. The concept of a multi-section climatic chamber is substantiated, design options are proposed, as well as a block diagram of automated control.

Hardware and software complex for modeling the modes of operation of an intelligent climate chamber in conditions of maintaining an optimal microclimate

“…Processing of incoming air by means of an air purification module in combination with complete isolation of the controlled zones from each other and from the external environment will create the necessary microclimate conditions in the plant growing area and achieve a high level of biological purity. The use of a carbon filter and an air ozonation unit will allow converting ozone entering into controlled plant growing areas into oxygen decontaminated from phytopathogenic microflora [2][3][4][5].…”

The assessment and ranking of factors of cultivation of cultivated plants in conditions of automated control of microclimate parameters

“…We propose a concept of a multi-section climatic chamber, which ensures the conditions of high biological purity in each section [7]. The device proposed will allow to implement simultaneously various combinations of microclimatic factors (the temperature and the air humidity, the spector and intensity of illumination, the concentration level of residual ozone, the level of air filtration and infiltration, the degree of air filtration, etc.)…”

“…𝑋 1 -means the temperature (t) inside the working chamber, °С; 𝑋 2 -means the temperature uniformity inside the working chamber ∆t, °С; 𝑋 3 -means the illumination level, lux; 𝑋 4 -means air filtration against bacterial contamination, which is achieved by the methods, which are safe for the plants; The output factor, which considers the efficiency of using the device for carrying out researches of a culture of plant tissues and cells, i.e., microclonal reproduction (in vitro), was taken as the output parameter at this stage of researches, this factor being the bacterial contamination of the air inside a section of the climatic chamber [7], which directly influences the condition of the growing medium and microclimate inside the test tube.…”
