Description

Plant Cultivation System

The present invention relates to a plant cultivation system, and more specifically, by implementing a space in which plants such as special crops are grown in a clean room form, while fundamentally preventing external contaminants or pests such as bacteria or fungi from entering from the outside. The present invention relates to a plant cultivation system capable of artificially creating an optimal environment in which plants can grow, and capable of mass-producing clean agricultural products with minimized management personnel.

In general, plant cultivation is traditionally a process of sowing and cultivating the soil in the open field and harvesting it. In particular, in the case of ginseng, it is usually cultivated and harvested for 6 years, and once grown, it has a difficult condition to grow again.

In addition, since cultivation in the open land is caused by natural environmental conditions due to wind, rain, and typhoons, there are also damages caused by natural bad conditions. It is inevitable.

In recent years, there are cases where it is cultivated in the soil in a hydroponic cultivation greenhouse or greenhouse house, but in this case, some air circulation is difficult to meet the air condition, and in winter, most of the warmth is released outside, and in summer, the plant is exposed to the hot environment. It is difficult to cultivate in optimum conditions.

In addition, in the case of some hydroponic cultivation, crops that can be easily cultivated by selecting a nutrient solution (養 液) well grow well, but in the case of high-income crops or special crops that grow under special environmental conditions, there is a problem that it is difficult to grow.

As an alternative to solving the problems of the conventional plant cultivation method, a plant factory is known.

The plant factory is a plant cultivation system that can artificially control the environment required for plant growth within a facility by lighting, air conditioning, and nutrient solution supply and continuously produce plants regardless of season.

Plant factories are able to produce stable throughout the year because crops are grown inside facilities where all environmental conditions are artificially controlled. In addition, since crops are cultivated and harvested in a systematic production facility, cultivated crops can be standardized and quantified, and rapid replacement of crops and quantity adjustment can be made more easily in response to changes in consumer demand trends.

Since the plant factory is indoor farming, it can be produced year-round, and farming can be done regardless of the weather. Therefore, the plant factory is expected to establish a new farming technology as a next-generation green industry and induce related high-tech development.

However, in order to cultivate a plant with high productivity in a plant factory, the growth conditions of the plant must be accurately controlled in a timely manner, and the growth cycle of the plant must be observed by a schedule to maintain appropriate growth conditions. In addition, in order to maintain proper productivity and lower production cost, it is necessary to prevent loss due to pests, and an optimal management system is required to minimize the input of management personnel.
