Description

A hydroponic cultivation system for improving growing and germination ratio of plant}

The present invention relates to a hydroponic cultivation system for improving plant growth and germination rate.

Hydroponics is a method of growing plants using water and water-soluble nutrients using an artificial medium or container capable of supporting plants without using soil, and is referred to as water cultivation, nutrient solution cultivation, and soilless cultivation. Such hydroponic cultivation has the advantage that the supply and management of fertilizer components are precise and there is no concern such as soil continuous cultivation, and the area is gradually increasing.

In addition, the advantages of hydroponic cultivation are that the state and growth of the roots can be directly observed, uncontaminated clean vegetables or plants can be continuously produced, and commercial mass production is possible. The multi-purpose indoor hydroponic cultivation device can be easily cultivated by anyone at home, so it can be used as a daily gardening and also plays a role in cultivating emotions.

Plants that can be grown hydroponically include dicotyledonous plants or mostly monocotyledonous plants with many beard roots, fruit vegetables such as cucumbers, tomatoes, peppers, paprika, and strawberries, leafy vegetables such as lettuce, lettuce, kale, water parsley, chrysanthemums, roses, gerberas, lilies, All flowers, such as begonia and anthurium, ginseng, and some medicinal plants can be grown hydroponically.

On the other hand, ginseng (ginseng) is a crop that requires long-term cultivation of 3 to 6 years, and the rest period in the field is usually more than 10 years, so the land productivity is very low compared to other crops. In addition, since they grow in the same location during the long growing season, soil characteristics and cultivation environment are more affected than other crops, and selection of suitable plantation sites has been recognized as the most important factor in determining the success or failure of ginseng cultivation. there is.

Studies related to ginseng cultivation in Korea include ginseng growth and soil characteristics, differences in elemental accumulation rates by parts of ginseng, and growth characteristics among ginseng component varieties by soil content and organic components. Among them, a number of studies have been reported on the physicochemical properties of soil affecting the growth of ginseng, and most of these studies have identified single substances and their mutual relationships, as well as complex interactions between soil factors, that is, the relationship with moisture in the soil. There is no research on nutritional imbalance in

In order to improve the productivity of ginseng, it is very important to accurately diagnose not only the soil characteristics but also the nutritional status of the plant. However, in other crops, many studies have been reported on plant leaf analysis for growth, quantity, and nutritional status, especially to set an appropriate concentration, but ginseng is incomplete. Therefore, in order to increase the yield in ginseng with weak resistance to rain and a narrow range of optimal fertility, it is necessary to set the criteria for suitable land for ginseng cultivation and the appropriate concentration in the plant body. Research on the environment is urgently needed.

Therefore, there is a need for a hydroponic cultivation technique capable of improving the growth and germination rate of plants and increasing the content of indicator substances in ginseng seedlings.
