Siheyuan: I am protecting Shazhu, who dares to object?

As global agricultural machinery continues to develop, agricultural production in some special environments has put forward higher requirements for machinery.

Wang Dashan led the Guangming Factory team to pay attention to these special areas, such as high-altitude cold areas, desert edges and saline-alkali land, and tried to break through the limitations of these special environments on agricultural production through innovative agricultural machinery solutions.

Wang Dashan first turned his attention to the high-altitude and cold regions in Northeast my country.

The winters there are long and cold, and the land is covered with ice and snow for a long time. Traditional agricultural machinery often faces problems such as difficulty in starting and easy damage to parts in such an environment.

Wang Dashan brought his technical team to a farm in Heilongjiang.

Brother Liu, the farm manager, frowned and said to Wang Dashan, "Manager Wang, you are finally here. When winter comes, our farm machinery is like frozen and doesn't work at all. Sometimes we finally start it, but it breaks down after working for a while, which makes us very worried."

Wang Dashan squatted down and carefully checked a tractor on the farm. He found that some parts of the engine had been frozen and the engine oil had become very viscous.

He stood up and said to the technical team: "We have to develop an agricultural machine suitable for high-cold environments. First of all, the engine must be specially designed and a heating device must be added to ensure smooth starting at low temperatures. For example, the engine can be preheated by electric heating, and the fuel injection system can be optimized so that the fuel can be better atomized and burned at low temperatures."

Xiao Zhang, a technician, said: "Director Wang, the materials of the parts also need to be improved. Ordinary metal materials tend to become brittle in cold environments. We can consider using some alloy materials with better cold resistance, or perform special treatment on existing materials to improve their cold resistance."

Wang Dashan nodded in agreement: "Xiao Zhang is right. In addition, we need to optimize the lubrication system of agricultural machinery and develop a lubricant with good low-temperature performance to ensure that all parts can be fully lubricated at low temperatures. In addition, in the design of the appearance of agricultural machinery, we must also take into account the impact of snow and ice accumulation, and add some snow removal and ice breaking devices to facilitate the driving of agricultural machinery in the snow."

After completing the investigation in the high-altitude and cold areas, Wang Dashan led the team to the desert edge area in the northwest.

The climate here is dry, the soil is severely desertified, water resources are extremely scarce, and there are strong winds and sand, which cause great wear and tear on agricultural machinery.

Xiao Li, a local agricultural technician, said to Wang Dashan: "Director Wang, our situation here is very special. Ordinary irrigation machinery is simply not applicable here because there is too little water. In addition, wind and sand often wear out the parts of agricultural machinery, and the maintenance cost is very high."

Wang Dashan looked at the vast desert, thought for a moment and said: "In this environment, we need to develop a water-saving agricultural machinery. For example, we can design an irrigation system that combines drip irrigation and micro-spraying to accurately control the amount of water and improve the efficiency of water resource utilization. At the same time, in order to cope with the erosion of wind and sand, we need to carry out special protective treatment on the outer shell and key components of agricultural machinery, use wear-resistant and corrosion-resistant materials, and add sealing devices to prevent wind and sand from entering the interior of the agricultural machinery."

Xiao Wang, a technician, said: "Director Wang, we can also consider developing an agricultural machine that can utilize desert wind and solar energy. This can not only solve the energy problem, but also reduce the impact on the environment. For example, we can install small wind turbines and solar panels on agricultural machinery to provide power for its operation."

Wang Dashan's eyes lit up: "This is a great idea. We can further study how to convert wind and solar energy into mechanical energy and achieve stable power supply and drive. This is not only of great significance to agricultural production in desert fringe areas, but also an innovative direction for global sustainable agricultural development."

Later, Wang Dashan shifted his attention to the saline-alkali land areas along the coast.

The soil here has a high salt content, which is very corrosive to agricultural machinery. In addition, the land fertility is low, making it difficult for crops to grow.

At an agricultural experimental station in saline-alkali land, the station director, Professor Chen, said to Wang Dashan: "Director Wang, agricultural development in saline-alkali land has always been a difficult problem. We have tried many methods, but the results are not ideal. Agricultural machinery here also faces serious corrosion problems and has a short service life."

Wang Dashan carefully observed the land and crops in the experimental station and said: "In view of the characteristics of saline-alkali land, we need to develop a corrosion-resistant agricultural machinery. First, the metal parts of the agricultural machinery should be treated with anti-corrosion methods, such as electroplating and coating, to improve their corrosion resistance. Secondly, the structural design of the agricultural machinery should be optimized to reduce the contact area with saline-alkali soil and facilitate cleaning and maintenance."

Xiao Zhao, a technician, said: "Director Wang, we can also develop an agricultural machine that can improve saline-alkali soil. For example, through a special tillage device, the improver can be evenly mixed into the soil to reduce the salt content of the soil and improve soil fertility."

Wang Dashan agreed: "Xiao Zhao's idea is very good. We should combine the research and development of agricultural machinery with the soil improvement of saline-alkali land to achieve multiple goals at one stroke. At the same time, we should cooperate with agricultural research institutions to jointly study crop varieties suitable for saline-alkali land cultivation and provide comprehensive solutions for the sustainable development of agriculture in saline-alkali land."

During the investigation and exploration of these special environments, Wang Dashan deeply realized that the innovation of agricultural machinery is not only a technological breakthrough, but also needs to be closely integrated with different agricultural production environments and needs.

Only in this way can we truly bring into play the role of agricultural machinery in global agricultural development and provide strong support for solving various complex agricultural problems.

After returning to Guangming Factory, Wang Dashan organized an internal seminar to share the research results and innovative ideas under special circumstances with all employees.

An old employee said with emotion: "Director Wang, we used to focus more on the research and development of agricultural machinery for ordinary farmland, but we didn't expect that there would be so many challenges and opportunities in special environments. This makes us see the broad prospects for the development of agricultural machinery."

Wang Dashan encouraged everyone, saying: "Yes, comrades. We must face these challenges bravely and continue to innovate. Although research and development under special circumstances is very difficult, as long as we work together, we will be able to overcome the difficulties and make greater contributions to the diversified development of global agriculture."
