Answer:
In China, the most common farming technique used to grow rice is the paddy field method. This involves growing rice in flooded fields, where water is maintained at a constant level. The soil is prepared by plowing, leveling, and adding fertilizers to improve the nutrient content.
South Korea also uses the paddy field method, but they have also adopted a more sustainable approach called the System of Rice Intensification (SRI). This method involves planting fewer seedlings at wider intervals and providing more attention to each plant. This results in higher yields and lower water usage.
In ancient Korea, one of the popular techniques used to preserve food was called jangdok, which involved storing food in jars with fermented soybean paste. The paste acted as a preservative and also added flavor to the food. This technique was widely used during the winter months when fresh produce was scarce.
Overall, both China and South Korea have developed sophisticated farming techniques to grow rice, with a focus on sustainability and maximizing yields. The jangdok technique is just one example of how Koreans have historically preserved their food, showcasing their ingenuity and resourcefulness in adapting to their environment.
