Amazing 15th-century Korean inventions: How did Korea create the world's first heated greenhouse?
A greenhouse is a structure designed to regulate the internal environment, including temperature and humidity. There are several different types of greenhouses on the market, but all have a transparent outer shell that allows sunlight to enter and prevents heat from escaping. Traditional greenhouses are typically constructed from glass or various plastic materials that effectively provide a comfortable environment in which plants can still grow during cold weather.
Greenhouses can range in size from small home greenhouses to large commercial greenhouses, which means they are quite flexible in design and use.
For much of history, the concept and use of greenhouses was limited primarily by climate. However, over time, particularly in 15th century Korea, an important technological innovation occurred. This innovation is not only a breakthrough in design, but also a huge boost to agricultural productivity as it allows a variety of vegetables and plants to be grown during the winter.
Historical BackgroundRoman Empire
The concept of a greenhouse dates back to the Roman Empire, when the Romans built the first artificial environment to meet the needs of certain privileged individuals. According to historical records, in 30 AD, in order to meet Emperor Tiberius' daily need for cucumbers, Rome designed a temporary environment to provide cucumbers all year round. During this process, the original form of the greenhouse gradually emerged.
Korea in the 15th century
The Korean design evolved further in the 1450s, resulting in the first actively heated greenhouses, which at the time formed a new model for agriculture.
The technology behind the invention was described by Korean Soon ui Jeon in his book Sangnongluk, which details how to build such a greenhouse and use the traditional Korean heating system, the ondol. ) to maintain indoor temperature, which was different from other designs at the time that relied solely on sunlight. The versatility and sophistication of this greenhouse put Korean agriculture ahead of most countries at the time.
Europe in the 17th century
As time went on, the concept of greenhouses was introduced to Europe. In the 17th century, greenhouse designs in the Netherlands and England were also influenced, and these greenhouses began to use glass and more modern building materials to improve production efficiency, marking a further development of greenhouse technology.
Development in the 19th century and beyond
With the advancement of science and technology, the design and materials of greenhouse structures have undergone many changes, especially in the 19th century, when the use of glass and iron opened up new possibilities.
During this period, glass houses in Britain became an important part of public coaching inns and exhibition halls, further promoting people's interest in tropical plants. As these technologies mature, many countries have gradually learned how to effectively control environmental conditions in greenhouses, and have continuously innovated to build large-scale modern greenhouses, linking agronomy with production and sales, thereby greatly improving the agricultural economy.
The influence of Korean greenhouse design
Today, greenhouses are widely used in various agricultural production, among which Korean greenhouse designs are still impressive. Korean greenhouses not only retain the traditional stove system but also incorporate modern technology to provide an ideal environment for plant growth. This advantage in controlling temperature and humidity allows many farmers to respond more flexibly to market demands.
ConclusionSouth Korea's greenhouses are undoubtedly leading an agricultural revolution, both in academia and business.
In 15th century Korea, the heated greenhouse based on the wisdom of Son Eui-jeon was not only a technological breakthrough at the time, but also influenced the agricultural development of later generations. This unique design and concept helped solve many of the challenges facing agriculture at the time. However, how will agriculture develop today, and what changes can green technology bring?
