The invention relates to the field of laboratory equipment to conduct scientific research with biological objects (plants, insects and so on) in an artificial climate. Can be used to study the effect of climatic factors on the processes taking place in biological objects, as well as for breeding with plants, the development of measures of protection of plants from pests using insect entomophages, etc.

Known cabinets, install, camera plant growth differ mainly in the number of playable climatic factors from among the following: light, temperature, humidity, carbon dioxide content, air velocity [1, 2]. The main components of such devices are glazed a working camera with a useful space for the studied objects, light sources, the air treatment module and the control unit [1]. Due to the fact that at the location of the light sources inside the working chamber in heat converted 100% of their installed capacity, the most widespread devices for mounting light sources behind the glass enclosure of the working chamber. With this arrangement, in the working chamber penetrates only about 35% of energy [2]. The closest analogue of the invention is to install microclimate vegetation is [3], containing glazed working chamber with glazed front door to monitor the plants, the light sources with mirror reflectors located on the outer side of the working chamber, the air treatment module and the control unit. The excess heat from the lamps is removed by the air conditioning unit air preparation. One of the most important climatic factors is light, because of photosynthesis in plants is their livelihood. Therefore, one of the main requirements to the devices artificial climate for plants is to provide the required illumination of the working chamber. In known devices, this is achieved by increasing the number of light sources, that is, by increasing energy consumption, that is their fault.

The aim of the invention is to increase the illumination of plants without additional energy costs.

This goal is achieved by the fact that Cabinet plant growth, containing glazed working chamber with glazed front door to monitor the plants, the light sources arranged on the outer side of the working chamber, the air treatment module and the control unit, the inner surface of the door provided with a mirror coating with a specified light transmittance, which is made in the form of pasted polymeric mirror plank is. Illumination in the working chamber is increased by reducing the loss of light radiation through the front door. And due to the fact that the mirror film is partially transmits the light remains and the possibility to observe the plants, without opening the door and not thus disrupting the established temperature-humidity conditions in the chamber. It is obvious that the additional cost of energy in this case does not occur, as there is no additional consumers.

Figure 1 shows the Cabinet plant growth; figure 2 - the same, with the door open; figure 3 - the same, with views of the sensors.

Wardrobe plant growth contains glazed the working chamber 1 with glazed front door 2, the inner side of which is pasted to the mirror plastic film 3. Inside the Cabinet there are four removable grid shelves 4 to install plants. On the outer side of the working chamber on the ceiling and three sides (two side and one back) are sources of light - the seven lamps 5 fluorescent lamps. Working the camera is mounted on the air treatment module 6, which contains actuators: air conditioner (cooler, heater and ultrasonic humidifier. Ceiling unit air preparation is the bottom of the working chamber after installing it on the air treatment module and has two longitudinal slits along Bo the new sides for air circulation. In the air treatment module is mounted, the control unit 7, basic elements of which are programmable in time, temperature controller, humidity, lighting 8 and the temperature sensors and humidity 9 and 10.

The work of the Cabinet of plant growth is to maintain the given parameters of the microclimate in the working chamber 1 with the aid of lamps 5, air-conditioner, heater, humidifier air treatment module 6, which is turned on and off under the control of the controller 8 based on the specified program values of temperature, humidity, time of switching on (off) lamps 5 and the current values of temperature, humidity and time received from the temperature sensor 9, the humidity sensor 10 and the timer of the controller 8. Illumination in the working chamber is created by lamps lamps 5 and the light reflected from the mirror of the polymer film 3 on the front door 2. The air circulates under the action of the fan of the air conditioner or heater unit air preparation 6.

The invention can be implemented using the following components. The frames of the working chamber 1 and the removable door 2 can be made of painted aluminium profile type CONSTA-SIB. The glazing of the window glass 4 mm thick with shlifovannymi edges with the use of the U-shaped plastic seals. As svetilniki can be applied to a standard type TL418-1A four fluorescent lamps 18 W with a special spectrum for plant type L18WW/77 FLUORA. To play the required values of temperature, humidity and light can be applied microprocessor software controller MPR-S ARIES, two resistance thermometer TC 034-50 M ARIES (one for measuring humidity with the psychrometric method) and actuators: air conditioning type LWJ0561ACG (LG, South Korea), fan REN 2036 and type humidifier PUH 1104 (both firm POLARIS, USA). The mirror coating on the inner surface of the door may be accomplished by gluing polymeric mirror film Llumar brand, for example, type R15GSRCDF (grey, with light transmission 15%). In addition to improving illumination in the working chamber SLR film reduces the negative effects of bright light from the back of the lamps through the door on the eyes of the researcher conducting experiments with plants.

The results of the measurement light on the shelves of the working chamber using a light meter "TKA-SUITE" with a mirror coating on the door and without it in the table.
