Problems in the development of agricultural machinery

Some insiders analyzed that although China's agricultural machinery industry has made great development, the gap with real agricultural mechanization is still very large, and the gap with foreign developed countries is also very large.

Shi Tie, vice president of Heilongjiang Academy of Agricultural Machinery Engineering Science, said that although Heilongjiang Province has already had an advantage in the country's agricultural machinery, it still lacks some farmland testing equipment. It can't measure soil sowing, soil testing and fertilization, and it is still in the intensive cultivation. There is a big distance.

He said that if farmers do not get up, it will restrict the development of agricultural machinery. The country's investment in agricultural machinery is gradually decreasing, and the investment is relatively insufficient. Foreign agricultural machinery is an input that is indirectly passed on. Foreign farmers are all insured, and once they are affected by the disaster, they will be guaranteed. This allows the government to conduct very detailed guidance on the cultivation, fertilization and drug disposal of farmers, such as the United States. This is an indirect investment in farmers, which is a virtuous circle. Ma Junwei, head of John Deere (China) Investment Co., Ltd., said that John Deere is one of the world's largest agricultural machinery companies, one of the top 500 in the world.

In 1997, China's first agricultural machinery joint venture was established in Jiamusi City, Heilongjiang Province. Since then, some joint venture wages have been established in Tianjin and Xinjiang. Compared with China's agricultural machinery companies, its advantages are mainly reflected in the design structure of the products, especially the suspension devices and transmissions. In addition, it is equipped with a precision farming system. It is fully automatic and easy to operate. Satellite positioning unmanned farming can be fully realized in the future.

According to Ma Junwei, John Deere's agricultural machinery has realized the production of assembly lines, and the parts are carefully selected from various manufacturers. Some of its agricultural machinery suspension systems are modified according to the suspension system of the US F-18 fighter.

Although there are gaps in China's agricultural machinery in this respect, it is not large, and some manufacturers produce parts that are already very standard. However, in terms of design concepts, design industrialization, rationality of assembly lines, and quality control, there is still a big gap between Chinese agricultural machinery manufacturers. China's agricultural machinery and equipment are still very backward, which has greatly affected agricultural production. Although Deere's agricultural machinery is more expensive, it is more durable than China's agricultural machinery. The cost of recovering agricultural machinery is about three to five years. Many domestic agricultural machinery have many mechanical failures when they just recovered their costs.

Farmers spend a lot of money to repair agricultural machinery, so the benefits will be greatly reduced. Ma Junwei said. Deere's precision agriculture system (modern agricultural management system) is very advanced. It can be said that the gap in this aspect in China is very large. Ma Junwei introduced that the precision agriculture system is equipped with information collection instruments and transmission instruments on the agricultural machinery. When the agricultural machinery is working, the information collection instrument will detect the operation status, and then send it to the satellite. The satellite analyzes and stores the information, and then performs the operation. Computer mapping, plotting the yield of the land, the situation of the fertilizer, the humidity of the land, etc., is then sent to the farmers, so that the farmers have an accurate estimate of the second year of farming.

Some land is planted on fertile land, and some pesticides are sprayed with more pesticides. The ground is heavily rooted and deeply cultivated. There are only two purposes for doing this: one is to increase the land use rate as much as possible; the second is to make the cost savings as much as possible.
