Description
Planting factory for various of vegetable in greenhousePlant factory is a high-efficiency agricultural system that realizes annual continuous production of
crops through high-precision environmental control in the facility. It uses computers to automatically
control environmental conditions such as temperature,humidity, light, CO2 concentration and nutrient
solution for plant growth. Labor-saving production that is not or rarely restricted by natural conditionsClassification of closed plant factory facilities
1. Idle factories and basements
Transforming these idle land resources into closed plant factories for high-yield, high-quality, and high-efficiency
plant production not only revitalizes idle resources, reduces costs, but also creates high value.
2. Abandoned containers
The artificial light-enclosed plant factory rebuilt from waste containers has the characteristics of good sealing,
high safety, good landscape, integrity, good structure, easy temperature control, convenient movement, long
service life, and strong environmental adaptability. A single box can become an independent plant factory,
multiple can also form a large plant factory, and multiple stacks can form a high-rise plant factory.
3. Foam board room
The artificial light plant factory built with foam sandwich panels has the advantages of light material, low cost,
short construction period, good sealing, etc. It can also be arbitrarily large, small, high and low, which is
convenient for the construction planning of internal facilities , widely favored by plant factory builders.
4. Inflatable membrane
Inflatable membrane is a fully enclosed structural space formed after infusing air with polymer materials (film
products made of high-strength carbon fibers and aerogels). The high-level three-dimensional plant cultivation
system built in such a structural space is called an inflatable membrane enclosed plant factory.The materials of
this inflatable house are high-strength carbon fiber, aerogel membrane and air. The outside uses solar energy
as energy, the inside is information intelligence and plant factory system facilities, and the middle is air. Such
an inflatable house enclosed plant factory has the advantages of low cost, strong sealing, good integrity, and
convenient use.Selection of the cultivation form of closed plant factory| Plane Multilayer Stereo Cultivation | In the container type closed plant factory, only two rows of cultivation racks can be designed. Due to the constraints of height
and space, the cultivation form can only be 3 to 4 layers. This is because the plane multi-layer three-dimensional cultivation
form can only use nutrient solution water. For the cultivation technology, each floor needs a nutrient pool, cultivation board,
LED supplementary light and vegetable plants and the space occupied by the cultivation rack. Generally, each floor is 65-70 cm, so
that the space for the cultivation area that can be expanded is limited. As a result, yields and benefits can only be improved
within a certain range. |
| Polyhedron Stereo Cultivation | The form of polyhedral three-dimensional cultivation bed can be replaced by nutrient solution hydroponics technology. Each group
of cultivation beds has only one nutrient pool. The utilization rate is higher, due to the realization of water, fertilizer and
gas supplementation, the plant grows faster, the cost is lower, the weight is lighter, and the yield is increased many times. If
the polyhedral cultivation form is adopted in the closed inflatable film plant To produce plants, the three-dimensional space is
larger, and the yield and benefit will be maximized |
| Curtain Wall Stereo Cultivation | Curtain wall three-dimensional cultivation is to cultivate plants on the walls of closed plant factories or artificially designed and constructed curtain walls,Cultivation beds are set up on the walls around the container, and plants are cultivated on the cultivation beds using the Chaoxi
culture technique. A nutrient pool is set under the cultivation beds, and LED supplementary lights are installed on the top of the
container. More adequate, more reasonable layout, more convenient operation, larger cultivation area and higher yield. If more,
taller and wider plant curtain walls are set up to cultivate plants in the closed inflatable film plant factory, the yield and
efficiency will be higher. |
| Vertical three-dimensional cultivation | Hanging the plant cultivation bed on the top of the closed plant factory, and then sowing, irrigating, fertilizing, and plant
protection on the hanging cultivation bed is not only a kind of agricultural production, but also an art of survival. In any
closed plant factory, the realization of vertical three-dimensional cultivation for agricultural production can not only expand
the area, increase yield, and increase efficiency, but also reduce costs and improve resource utilization, which is not only
environmentally friendly, but also facilitates sustainable production; not only It is easy to operate and enhances the life
experience. |
| Cylindrical Stereo Cultivation | Plants are planted on the surface of the cylinder, the three-dimensional cultivation area is larger, and the aeroponics technology
is used, the plants grow faster. However, in the closed container type plant factory, because the environmental space is too
small, it is not suitable to use a cylindrical three-dimensional cultivation device. However, in other types of closed plants,
especially in the closed plant factories with air-filled membranes and air-tight membranes, the advantages of cylindrical
three-dimensional cultivation will be brought into play for a longer period of time |
Main featuresThe common features of plant factories are: fixed facilities; automatic and semi-automatic control of temperature,
humidity, light intensity, light time and CO concentration required for plant growth and development by using
computers and various sensing devices; using nutrients Hydroponics technology; the quantity and quality of
products are greatly improved.Fold and harvest fast
Through the high-precision control of the environment in the factory, the growth of plants here is almost not
restricted by natural conditions, and the growth cycle is accelerated. Lettuce, cabbage, etc. grown in the factory
can be harvested in about 20 days, while in ordinary fields , it will take one month to 40 days. In addition to
fast harvesting, high space utilization is also an important feature of plant factories. What we see in the factory
are the three-layer cultivation racks, which are equivalent to three times the open-air cultivated land of the same
size in terms of area. In addition, the planting density is high. Therefore, the output of the plant factory can reach
dozens or even higher than that of conventional cultivation. Hundred times, the cycle of seedlings is shorter,
generally about a week.Folding Environment Requirements
The plant factory uses energy-saving plant growth lamps and LEDs as artificial light sources, and adopts 13
interrelated control subsystems such as cooling-heating bidirectional temperature and humidity control,
light-carbon dioxide coupled photosynthesis and gas fertilizer control, and nutrient solution online detection
and control. It can automatically monitor the temperature, humidity, light, airflow, carbon dioxide concentration,
nutrient solution and other environmental elements of the plant factory in real time to achieve intelligent
management.
