"There are no books in the library" is about reading e-books and laser machines. People store words, pictures and other information in electronic computers and record them on optical disks, which has the characteristics of low cost, fast retrieval, printable and convenient reading.
1July, 990, Wu Dawei participated in the study of agronomy in dengta city Branch of Liaoning Agricultural Broadcasting and Television School. After graduation, he applied his scientific and technological knowledge to agricultural technology popularization, and was named as the leader of science and technology spark in Liaoning Province by 1995, and was affectionately called the leading geese to get rich by the surrounding farmers.
1996, Wu Dawei contracted more than 200 mu of land in three villages for experiments, introduced new varieties and technologies, and built a solar greenhouse covering an area of 1000 square meters and a greenhouse covering an area of 6,000 square meters to grow watermelons, which achieved good results. Driven by him, the watermelon planting area in the whole town increased from 1.997 to 1.000 mu. This technology alone will increase farmers' income by more than 2,000 yuan per mu.
Dahenan Town is mainly engaged in field production, but there are some problems in seedling raising and water saving. Through the study, Wu Dawei mastered the non-woven bowl seedling raising and water-saving cultivation techniques. In the past five years, he has given more than 400 lectures to farmers and spent more than 3,000 yuan on experimental demonstration funds every year. Let farmers realize the benefits of simplifying rice planting. In recent years, the cultivation area of non-woven seedling raising and seedling throwing has reached more than 1 10,000 mu. This labor-saving, time-saving and high-yield technology has been mastered by most farmers.
Wu Dawei never kept his research results and selflessly passed them on to farmers. He improved the yield and quality of grain and vegetables, and made many farmers use his technology to get rid of poverty and become rich. He is the author of agricultural books such as Agricultural Development, Future Science and Technology, How to Increase Agricultural Output, High-quality Agriculture and Vegetable Planting.
Shops Without Customers is about using two-way TV to shop, and you can browse stores in various countries without leaving home, saving time and effort.
Farming without Land is about soilless culture. This technology is to artificially create the best environment for crop growth by using nutrient solution, containers and gravel according to the requirements of crops for soil. This method saves land, is convenient to manage and is not limited by disasters and seasons.
There are no workers in the factory, which is about using robots for production. Robots are flexible, sensitive and versatile. In the robot era, "human labor is just a demonstration and switching buttons", which can not only liberate the labor force, but also improve work efficiency.
The above example shows that with the development of science and technology, great changes will take place in the future society. In order to meet the needs of the future society, we should love and learn science. 1July, 990, Wu Dawei participated in the study of agronomy in dengta city Branch of Liaoning Agricultural Broadcasting and Television School.

The seedling throwing machine invented by Wu Dawei, the manager of dengta city Sannong Service Company, recently won the national invention patent.
In recent years, Wu Dawei has been thinking about the problem of mechanical seedling throwing, and has done a lot of research and experiments. In 2000, he used the blower on the sprayer to match the tray with the seedlings, and with the help of wind, he threw the seedlings into the air and landed in the paddy field. After repeated research and experiments, he finally succeeded. Since 200 1, dengta city Sannong Service Company has increased the mechanical seedling throwing project for farmers. Compared with manual seedling throwing, mechanical seedling throwing improves work efficiency. It only takes more than 10 minutes for one manipulator per acre, and the cost is 10 yuan. Since its introduction, this service has been widely welcomed by farmers. The annual operation area of Sannong Company increased from the initial several hundred mu to more than 30,000 mu in 2004.
After four years of production practice, the seedling throwing device and operation technology were continuously improved, which made this technology mature day by day (Qin), and the national patent was declared in June 2004. At present, entrusted by Wu Dawei, the seedling throwing machine has been produced by two manufacturers, Zhejiang and dengta city, and customers from three northeastern provinces, Zhejiang, Jiangsu, Hebei and Ningxia have come to order.
