Courtyard House: Primordial Chaos Pearl

A few snowflakes drifted down in the early winter suburbs of Beijing, but the R&D center of the Hongxing Agricultural Machinery Industrial Park was warm and inviting. Lin Dongzheng, He Yushui, and Yan Jiecheng were discussing a sand table model—the "Hongxing-80" intelligent irrigation machine, designed specifically for oases on the edge of the desert. It combines precision seeding and drip irrigation technologies and is another key project following the water-saving seeder aided in Africa.

"The temperature difference between day and night is large in desert areas, and the soil has poor water retention capacity. Ordinary drip irrigation systems cannot automatically adjust the amount of water according to soil moisture." He Yushui pointed to the sensor model in the sand table, "We need to install a soil moisture monitoring module on the seeder to realize the integrated operation of 'seeding-irrigation-fertilization', so as to save water resources to the greatest extent."

Yan Jiecheng held the newly printed circuit board, his eyes gleaming: "I've tripled the sensitivity of the sensor, enabling it to accurately detect changes in soil moisture content, with the data transmitted to the central control system in real time. But there's still a problem—the desert is windy and sandy, and the sensor probes are easily clogged by sand, affecting monitoring accuracy."

This problem stumped the research and development team. Lin Dong, however, remembered a modified nylon material cultivated in the chaotic space. This material had a special hydrophobic and sand-repellent coating on its surface, causing sand to automatically slide off. He immediately decided to use this material to make the outer shell of the sensor probe, and then add a miniature dust cover for double protection against wind and sand.

The day after the plan was finalized, representatives from the Xinjiang Production and Construction Corps came to visit. They brought soil samples from an oasis on the edge of the Taklamakan Desert and urgently hoped that Hongxing Factory could develop intelligent irrigation machinery as soon as possible: "The oasis there is desertifying every year. If we can preserve the arable land, we can protect our homeland."

Lin Dong patted his chest and guaranteed, "We will definitely produce a prototype that can be put into operation within three months!"

As research and development entered its final sprint, the entire industrial park sprang into action. Jia Dongxu's supporting factory was responsible for producing the casing of the intelligent central control system, and in order to meet dustproof and waterproof standards, he specially introduced new injection molding equipment; Yi Zhonghai, despite his leg problems, came to the R&D center every day, using his experience from his youth to help optimize the layout of irrigation pipes and reduce water flow resistance.

Liu Haizhong was also extremely busy in the canteen, preparing a variety of nutritious meals for the R&D team every day. He even specially asked someone to buy red dates and walnuts from Xinjiang to help everyone improve their health. His daughter, Liu Lan, organized the "Little Agricultural Machinery Guardians" club at the school for children of employees, taking the children to visit the R&D center and cultivating their interest in agricultural machinery technology from a young age.

Three months later, the prototype of the "Hongxing-80" intelligent irrigation agricultural machine rolled off the production line as scheduled. The test site was chosen on the edge of an oasis in Xinjiang. As the machine slowly drove into the sandy land, the sensors automatically drilled into the soil to detect the moisture level, the seeder accurately planted the seeds, and the drip irrigation system started up. When the water flowed precisely into the roots of each seedling through the pipes, the representatives of the Xinjiang Production and Construction Corps applauded excitedly.

After a week of continuous testing, the machine operated stably in windy and sandy weather, maintaining optimal soil moisture content. The survival rate of sown wheat seedlings was 50% higher than that of traditional methods. The Xinjiang Production and Construction Corps immediately signed an order for 2,000 units and invited Hongxing Factory to establish a technical service station in the area to train farmers on how to operate the machines.

Just as orders in Xinjiang were being fulfilled at full capacity, even more exciting news came from overseas. Water-saving planters in Africa doubled local corn yields, and agricultural departments in several African countries expressed their intention to cooperate, hoping to introduce Red Star Agricultural Machinery's complete technology. Distributors in Southeast Asia also reported good news: combine harvesters adapted to hot and humid environments have captured 30% of the local market share, completely breaking the monopoly of European brands.

At the end of the year, the Ministry of Agriculture awarded Hongxing Agricultural Machinery Industrial Park the title of "National-level Agricultural Equipment R&D Demonstration Base," and Lin Dong was also named a "National Advanced Worker in Agricultural Science and Technology." At the commendation ceremony, Lin Dong held the trophy, looked at his colleagues below the stage, and was filled with emotion.

From a small side room in a traditional courtyard house to a multinational agricultural machinery enterprise; from a simple harvester to intelligent agricultural machinery all over the world, the hardships and glory along the way are engraved on the nameplate of every Red Star agricultural machinery.

On New Year's Eve, the staff canteen in the industrial park was brightly decorated. Lin Dong held Lin Xiangyang, who could already run and jump, while He Yushui nestled beside him, her eyes filled with happiness as she looked at the room filled with laughter and joy. Yi Zhonghai, Liu Haizhong, Yan Bugui's family, Jia Dongxu and his wife, and the factory workers all sat together, eating steaming dumplings and chatting about their New Year's wishes.

"Next year, we're going to build an assembly plant in Africa, so that Red Star agricultural machinery can take root and flourish there!" Jia Dongxu said loudly, raising his glass. "We also want to promote intelligent irrigation machinery to Central Asia, along the Silk Road, so that more people can use our excellent machines!" Yan Jiecheng echoed.

Lin Dong smiled, raised his glass, and said to everyone, "In the new year, let's stay true to our original aspirations and continue moving forward. Let the roar of Red Star agricultural machinery resound across every field in the world!"

The clinking of glasses was crisp and clear, and fireworks outside the window illuminated the night sky. Lin Xiangyang, nestled in Lin Dong's arms, babbled "Daddy," clutching a dumpling wrapper in his little hand, his smile innocent and carefree.

Lin Dong looked down at his child, then gazed at the brilliant starry sky outside the window, his heart filled with boundless hope. He knew that his journey was to the stars and the sea, and that the mission of Red Star Agricultural Machinery was to make every inch of land bloom with the green of life.
