For example, in terms of new employee training models, retention of core employees, and leveraging employee motivation; Ensure independent control of key components and processes; Continuously pursuing more advanced production equipment; A testing center with high levels of automation and comprehensive capabilities. The difference in material strength, fastening method, and material level is an important reason for the larger weight and lower reliability of domestic agricultural machinery.




Huang Kaipeng believes that the method of mixed line assembly can quickly meet market demand and adapt to differences in customer needs. However, it requires employees in management, research and development, production, procurement, and other aspects to have higher levels of ability; The commonly used model of developing product functions and pre production in China has the advantages of lower storage pressure and execution difficulty for components, but it is difficult to adapt to market changes in a timely manner, which can easily lead to product inventory backlog. By establishing a self operated R&D testing ground and planting crops according to the R&D plan, enterprises can more effectively shorten the testing time and improve the testing efficiency.




Gao Lei, from the Hohhot Branch of the Chinese Academy of Agricultural Machinery, first reported on the inspection of lawn mowing machinery, spreading and drying machinery, strip collection machinery, and bundling machinery. He pointed out that most foreign round bundling machines use belt form and are mainly used for silage operations of forage. The roller type round bundling machine compresses materials from the outside in, so the core is relatively loose, which is conducive to long-term outdoor storage of bundling. It is more suitable for bundling yellow storage materials such as straw, so most round bundling machines in China are roller type; It is believed that the development of large-scale combination lawn mowers, strippers, belt wrapped film round bundling machines, self-propelled large diameter bundling machines, and silage wrapping machines based on forage production and harvesting will be an important direction for the development of forage production and straw collection and bundling equipment in China.
