　　國(guó)產(chǎn)農(nóng)機(jī)技術(shù)落后在哪里？不止是50年的差距（英文版）

A large Number of Applications of Intelligent Information Technology

Most of China's current agricultural machinery technology is still in the mechanization stage, and automation has not yet been popularized. There are only a few applications using intelligent technology. The European and American agricultural machinery products have applied a large number of intelligent and information technology.

For example, large tractors and combine harvesters using GPS positioning systems to accurately guide users in various operations; production systems, driverless technologies, intelligent control systems, and precision agricultural solutions.

High Efficiency Multi-functional Composite Operation

With the continuous reduction of cultivated land areas and the increase of labor costs, European and American agricultural machinery technology pays more attention to productivity, safety and comfort. Therefore, high-efficiency, multi-functional and composite work tools are widely used.

Benefited by this innovative automation technology, the efficiency of the combine harvester has been maximized, and the overall efficiency has been improved by 15% to 18%. The application of this system can increase crop production capacity, improve work efficiency, and make a positive contribution to ensuring food security.

The compound operation function is particularly evident in the supporting agricultural tools. China's agricultural implements have relatively simple functions, while almost all European and American agricultural implements have achieved multi-functional and compound operations, large-scale, high work efficiency, reduced number of landings, reduced soil compaction, and reduced operating costs.

Plant protection machinery is developing in the direction of large-scale, intelligent and precise, low-volume spray technology, automatic target application technology, anti-drift technology and precision application technology.

Pay Attention to the Protection of the Environment

The technological innovation trend of foreign agricultural machinery products not only highlights the advanced technology, but also pays more and more attention to the protection of the environment, which mainly reflected in the following aspects.

1 zero emissions or fewer emissions.

Several major international agricultural machinery giants have launched new energy tractors and started trial trials.

2 not use, use less chemical pesticides (herbicides), or improve the efficacy.

For example, the weeding machine produced by Company Caffini of Italy uses only high-pressure water for weeding between trees. The unit is equipped with a high pressure pump, a nozzle rotator and a rotating nozzle, and high pressure water is sprayed onto the soil to chop the weed roots. The application of this system reduces the impact of environmental of the weeding process to almost zero.

3 reduce the compaction of the soil.

For example, Trelleborg tires can adjust the tire pressure according to the load change. The harvester equipped with the tire can adjust the tire pressure according to the actual load during operation, so that the tire traces are always consistent. In this process, the tire pressure can be automatically adjusted without the need of operator, reducing soil compaction.
