Science and technology change life, the times are gradually changing, and science is constantly improving. The development of science and technology has brought a lot of convenience to our life, and our life is closely related to science and technology.

In the past, every spring, farmers' uncles had to sow, sow and so on. In summer, they have to kill insects. In autumn, they have to be busy harvesting and planting other crops. They have to repeat the same sequence every day all year round, hunched over every day, and often exhausted themselves. But sometimes the weather will be cloudy or sunny, with several heavy rains or several days of drought, coupled with serious environmental pollution in some places, pests can be seen everywhere, which is enough to make crops unable to grow, but the hard work of farmers is in vain.

Now, with the development of science and technology, a new cultivation method-space breeding has been brought. It is a kind of carrying scientific experiments, carrying crop seeds on a recoverable ground satellite, making the seeds mutate with the help of unpredictable environmental changes on the ground, such as ultra-vacuum microgravity and cosmic rays, and obtaining stable genetic traits through multiple generations of ground breeding, thus cultivating new agricultural varieties.

Since 1987, scientists in China have carried out experiments on carrying a variety of plants in space by using recoverable ground satellites, and cultivated a series of new crop varieties such as rice, wheat, tomato, green pepper and sesame with high yield, high quality and multi-resistance. Space breeding has been applied to a certain extent. The weight and shape of fruits brought from space have changed, which are much larger and more delicious than those cultivated on land.

The door of science has been opened, and the convenience brought by science and technology can be seen everywhere. In the future, the development of science and technology needs us to explore and create. Let's plug in the wings of science, roam freely in the world of science, discover and explore the science in life, and contribute to the future science and technology.
