Description

Plant growing plant {PLANT FACTORY}

The present invention relates to a plant cultivation plant which can increase the photosynthesis of a plant by providing LED light inside the plant cultivation structure and supply a suitable amount of air purified in the nutrient solution of the plant cultivation structure to the roots of the plant .

Generally, plants are cultivated by the supply of soil nutrient solution, sunlight, and water supply by rainwater supplied during rainfall, and the cultivated crops are harvested and used as agricultural products.

However, there is a problem that the cultivation of such crops is influenced by the weather, and the harvesting time and yield are largely influenced by weakening of weather conditions such as abnormal high temperature, abnormal low temperature or strong wind, heavy rain or typhoon.

Thus, a plurality of pipe - shaped cultivated areas were planted in a cultivated area in the form of houses in a cultivated area, and a plastic house covering the upper part of a plurality of frames with vinyl was developed and used mainly in rural areas. The greenhouse blocks direct damage to the crops by strong winds and heavy rainfall, thus inhibiting growth inhibition factors to promote plant growth.

It is also possible to use various kinds of vegetables, flowers, fruit trees, and the like which are not able to be cultivated under the conditions of the outside air and temperature, respectively, by covering a heat insulating material on the upper part, a warming means such as a boiler on the inside, It is mainly used because special crops can be cultivated.

However, the conventional vinyl house has a problem in that the replacement time is short due to the weak vinyl strength, and the cost of replacement is incurred, and crops that are destroyed due to the wind pressure of strong typhoon or snow pressure due to heavy snowfall are damaged . In addition, due to the continuous use of the soil, as the nutrient solution of the soil is exhausted, the growth of the plant is lowered, and the pesticide is used for promoting the growth, but the soil and cultivated matter are contaminated. Therefore, there has been a problem in that it takes a long time and the efficiency of promoting the growth is lowered, though it is cultivated by using environmentally friendly fertilizer or supplementing soil nutrient solution with a resting period not being cultivated for a certain period of time.

Recently, a hydroponic cultivation method has been developed in which a nutrient solution is fed to a crop at a certain place without being cultivated in a soil. As a result, crops are produced by supplying nutrient solution, and thus pesticides or fertilizers are not used. It is widely used. Such a hydroponic cultivation method can grow various vegetables, ginseng and the like, but with the continuous research and development, the kinds of the cultivated plants are increasing.

Conventional hydroponic cultivation has been cultivated in facilities using sunlight such as vinyl houses and greenhouses. Recently, however, environmental conditions such as light, temperature, humidity, carbon dioxide concentration and culture liquid have been artificially controlled A plant plant was developed that automatically produces continuously regardless of season or place. A plant is a facility that controls temperature and humidity, and uses artificial light sources to produce crops stably throughout the year regardless of weather and season.

However, although the above-mentioned plant plant can supply the air required for the plant by supplying and circulating the outside air to the inside, there is a problem that the outside air is introduced into the plant without being purified, and the plant is contaminated. There is a problem in that the growth of plants can not be promoted.
