34 years ago, a legend said, "the popularization of computers should start with child education", which changed many people’s lives of and marked the beginning of an era.

Nowadays, many factors, such as energy crisis, food safety problems and lack of labor force, promote the transformation from traditional agriculture to modern agriculture. Although China is a large agricultural country, it is not a powerful country. The popularity of modern agricultural development is not extensive. If we want to catch up with developed countries in agriculture, not only need technological innovation, but also agricultural education is imperative.

In order to let more teenagers get more knowledge about modern agriculture, agricultural energy conservation and emission reduction, green energy etc., and understand the connotation of "science and technology is the first productive" in agriculture industry. With the support of Shanghai Jinshan youth practice center, Jintang agriculture United UPuper^® rock wool has brought a unique lesson to contemporary teenagers.

Through the explanation of the person in charge, the students learned about the development of traditional agriculture and modern agriculture. At the same time, they understood that, through precision planting, UPuper^® rock wool substrate can realize the characteristics of high yield and quality, energy saving and efficiency, water and fertilizer saving of modern greenhouse which is very suitable with the development of modern agriculture.

Only combining theory and practice can achieve maximum teaching effect of activities. Under the demonstration of the person in charge, the students operated soilless cultivation from sowing, transplanting and cutting.

In a series of practical operations, students understood many differences and advantages between modern soilless cultivation and traditional cultivation. At the same time, they also realize that UPuper^® rock wool substrate is more convenient, fast and clean. It is not only suitable for planting in large-scale greenhouse, but also suitable for planting in family gardening.

After learning and practice, the tomato plants cut by students are also given to themselves as gifts. We hope everyone can cultivate green and healthy tomatoes.

Although the half day period study is very short, I believe it will make young people who have participated in agricultural activities change their outlook on agriculture. The traditional agriculture by working on the outdoor farm will be gradually replaced by intelligent and modern greenhouse. We can cultivate high-quality fruits and vegetables efficiently through using superior rock wool substrate and corresponding supporting facilities. In the future, they are not only beneficiaries, but also the most indispensable backbone in agricultural development.
