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

In the 60s, the countryside was filled with the spirit of struggle. Green agricultural machinery still faced many difficulties in its continued promotion. However, people from all over the country were not intimidated by the difficulties. Instead, they worked together to make green agricultural machinery better serve agricultural production and help the countryside realize the dream of a good harvest.

On the edge of a vast grassland in Africa, there is a place called Grassland Village. Although the land here is fertile, it is often invaded by wild animals, which brings great inconvenience to the planting and harvesting of crops.

The alliance's technical team came here with green agricultural machinery with special protective designs, hoping to help the villagers solve this problem.

As soon as Wu Feng, the head of the technical team, transported the machinery to the village, he was surrounded by villagers.

The village chief, Mohammed, asked with a look of expectation and a little worry: "Mr. Wu, there are often wild animals around our village. They don't care what is planted in the fields and often come to destroy the crops. Can your machine stop them?"

Wu Feng pointed at the machines and introduced them in detail: "Village head, look at these harvesters and seed drills. We have installed special protective fences for them. The fences are made of strong and durable metal materials, and they are high enough that it is difficult for ordinary wild animals to climb over. In addition, the machines themselves are equipped with some devices that can emit special sound waves. These sound waves have a repelling effect on wild animals and prevent them from approaching."

Ali, an old herdsman in the village, stroked his beard and said doubtfully: "Young man, these wild animals are very wild, how can they be scared away so easily? What if they are not afraid of the sound waves and still rush in and damage the machine? What should we do then?"

Wu Feng patiently explained: "Uncle Ali, we have conducted tests in places with similar situations in the early stage, and the effect is quite obvious. But to be on the safe side, we have also prepared some spare protective nets. If wild animals really try to get close to damage, we can quickly pull up the protective nets to strengthen the protection. Now we can go to that piece of crop field and show everyone the actual operation."

So everyone came to the farmland outside the village.

Wu Feng directed the technicians to start the machinery and turn on the sonic repellent device.

The machines began to operate normally, harvesting the ripe crops in the fields. After hearing the sound waves, the wild animals that were originally wandering nearby ran away and dared not approach the area.

When the villagers saw this scene, they cheered in surprise.

Hassan, a young villager, shouted excitedly: "Wow, this is amazing. In the past, we had to send people to guard the land every day for fear that wild animals would disturb us. Now it's great, we can farm with peace of mind."

However, the good times did not last long. That night, a group of elephants, for some reason, seemed unaffected by the sound waves and walked towards the fields.

After the villagers who were on night watch discovered this, they hurried to inform Wu Feng and others.

Wu Feng rushed over with his men, quickly put up the spare protective net, and increased the power of the sonic device, only then did they drive the elephant away.

Uncle Ali said with lingering fear: "Oh, this elephant is so scary. Although the protection of this machine is somewhat useful, it is still not very safe."

Wu Feng said quickly: "Uncle, this is indeed an unexpected situation. The elephants' hearing may not be very sensitive to our sound waves. But we will further study and improve it after we go back to see if we can adjust the frequency and intensity of the sound waves so that it can better drive away all wild animals. In addition, we can also set up some simple obstacles around the village to help prevent wild animals from approaching the crops."

After this incident, Wu Feng and technicians stepped up efforts to improve the mechanical protective devices. They constantly adjusted the parameters of the sound waves, and together with the young and middle-aged people in the village, set up some obstacles made of wood and thorns around the village.

As the days passed, the machines were no longer seriously disturbed by wild animals when working in the fields, the crops were harvested smoothly, and the yield was greatly increased compared to the past.

The village chief, Mohammed, said to Wu Feng happily: "Mr. Wu, thank you so much. If it weren't for the magical machines and protective measures you brought, our crops would not have such a good harvest. Now our village has hope for the future."

Wu Feng responded with a smile: "Village Chief, this is the result of everyone's joint efforts. As long as we continue to find ways to improve it, our future will definitely get better and better."

In an ancient village in Europe called Rose Village, there is a long agricultural tradition. However, with the development of the times, traditional irrigation methods can no longer meet the needs of crop growth.

The alliance's team of experts came to the village with a new intelligent irrigation system, hoping to change the current irrigation situation here.

As soon as Professor Liu from the expert team installed the smart irrigation system, the village chief Pierre came over and asked, "Professor Liu, we have always relied on manual water carrying or simple ditch water diversion for irrigation. Although it is troublesome, it has been so many years. Can we operate your smart irrigation system? And is it really better than our original method?"

Professor Liu pointed to the control device of the irrigation system and introduced: "Village head, look at this control device. It is very easy to operate. There are clear icons and text prompts on it. Just set the irrigation time and water volume according to the needs of the crops. Moreover, this system is very intelligent. It can automatically detect when to water and how much water to water based on the moisture of the soil. It can accurately control it, which is much more accurate than our manual judgment. This can ensure that the crops have enough water without wasting water resources."

Jacques, an old farmer in the village, came over and looked at the complicated control device. He frowned and said, "Young man, this looks very complicated. We are all farmers with little education. If we set it wrong, the crops will be flooded or die of thirst. That would be terrible."

Professor Liu patiently explained: "Uncle Jacques, don't worry. We will stay here for a while and teach you how to operate it step by step. When you first start using it, we will help you set the parameters. Once you are familiar with it, it will be easy to use. Now I will show you how to operate it."

As he spoke, Professor Liu began to demonstrate. He first showed everyone how to check the soil moisture data, and then set the corresponding irrigation time and water volume on the control device according to the current growth stage of the crops.

After the setup was completed, the irrigation nozzles sprayed water evenly onto the ground according to the set program. The precise level of irrigation amazed the villagers.

Lucy, a young villager, shouted excitedly: "Wow, this is so convenient. In the past, we always couldn't control the amount of water when watering, either too much or too little. Now it's much easier."

However, after a few days of use, new problems emerged.

For some reason, the irrigation sprinklers in one field were spraying water unevenly, with more water in some places and less in others.

When Professor Liu learned about it, he went to check it out immediately.

After inspection, it was found that a small part inside the nozzle was blocked, affecting the water spraying effect.

While cleaning the parts, Professor Liu said to the villagers who gathered around him: "Although this irrigation system is advanced, the nozzles are left outside for a long time and are easily blocked by impurities or dust in the water. In the future, we should regularly check the nozzles and clean out the debris inside to avoid this situation."

Uncle Jacques grumbled to the side: "Ah, this new thing is so delicate, and it takes so much effort to take care of it."

Professor Liu smiled and said, "Uncle, you have to be more careful when you first use it, but once you get used to it, regular maintenance won't be a problem. You see how much convenience this smart irrigation system brings to our watering. Crops can grow better, and our harvest will be more secure."

Since then, Professor Liu has led the villagers to develop a detailed maintenance plan for the irrigation system, and everyone checks and cleans key components such as sprinkler heads at regular intervals.

Slowly, the intelligent irrigation system has been operating steadily in Rose Village. With sufficient and precise irrigation, the crops in the village are growing stronger and stronger, and a good harvest is in sight.

In villages around the world, green agricultural machinery and related innovative technologies are overcoming one problem after another through everyone's concerted efforts. They are blooming brilliantly on the rural land, helping every village to move steadily towards a good harvest and a better life. These stories full of sweat and hope will be forever engraved in the long history of rural development, inspiring future generations to keep exploring and moving forward.
