Siheyuan, integrating everything, cultivating the city

In the dead of night, Li Xiangqian lay in bed, thinking about every detail of this period. He couldn't help but think that he had gone from being an ordinary young man to being able to lead everyone to cultivate the land. This change made him feel deeply moved. He knew that this was not only his own growth, but also the efforts and support of everyone in the courtyard.

The next morning, Li Xiangqian got up, picked up a book about agriculture, and continued to study soil improvement methods. He knew that knowledge was the most important weapon, and only by continuous learning could he better solve practical problems.

One day, he was immersed in a book when he suddenly heard Xiao Liu calling from the yard: "Xiao Li, come and have a look, there are some problems here!"

Li Xiangqian quickly put down his book and ran to Xiao Liu. Xiao Liu pointed to a patch of soil and said, "It seems that there are still some problems with the soil here. The crops are not growing well."

Li Xiangqian squatted down and took a closer look. He found that the soil quality of this land was indeed not very good. He thought for a while and said, "Xiao Liu, we can try to apply organic fertilizer again and water it more to see the effect."

Xiao Liu nodded in agreement, "Okay, I'll get ready right away."

Li Xiangqian looked at Xiao Liu's busy back, and a warm feeling welled up in his heart. Everyone is working hard for this piece of land, and he must work harder to live up to everyone's expectations.

As time went by, the efforts of Li Xiangqian and his neighbors gradually paid off. The farmland in the courtyard became more and more fertile, and the crops grew better and better. Everyone's face was filled with joy, and everyone was proud of the changes in the land.

One day, Uncle Li came to Li Xiangqian and said with a smile: "Little Li, our land has really changed a lot now. I really have to thank you very much."

Li Xiangqian smiled modestly and said, "Uncle, this is the result of everyone's joint efforts. Without your support, I couldn't have done it alone."

Uncle Li patted him on the shoulder and said, "You are a young man. You are not arrogant or impatient, but hardworking and down-to-earth. You are really great."

Li Xiangqian looked at Uncle Li with gratitude, and his heart was filled with emotion. He knew that there would be many challenges waiting for them in the future, but as long as everyone was united, no difficulties could stop them from moving forward.

Li Xiangqian stood beside the farmland in the courtyard, thinking about his next plan. He realized that to improve the yield and quality of the farmland, more expertise and resources were needed. At this time, he thought of Yi Zhonghai, an old friend who was very experienced in the field of agricultural technology.

Yi Zhonghai used to work at an agricultural research institute and had extensive research on soil improvement and high-yield crop planting. He had retired and Li Xiangqian thought this might be a good opportunity, so he asked him to guide the improvement of the arable land in the courtyard.

One weekend afternoon, Li Xiangqian made a special visit to Yi Zhonghai. Yi Zhonghai lived in a small courtyard not far from the Siheyuan. Although he had retired, he still maintained his passion for agriculture. Li Xiangqian knocked on the door, full of anticipation and a little nervousness.

The door opened, and Yi Zhonghai came out with a big smile on his face. "Xiang Qian, long time no see. How come you have time to come here today?"

Li Xiangqian smiled and responded, "Uncle Yi, we have been working on improving the farmland in our courtyard recently and have encountered some problems. I came here to ask you for advice."

Yi Zhonghai nodded and asked Li Xiangqian to go in and sit down. "Come on, come in and sit down. Let's talk slowly."

The two sat down at the tea table, and Li Xiangqian described in detail the farmland conditions and problems encountered in the courtyard. Yi Zhonghai listened carefully and nodded from time to time to show his understanding.

"Xiang Qian, I appreciate your efforts," Yi Zhonghai said, "but solving the soil problem does require some expertise and technology. I am willing to help you, but we need to reach an agreement."

Li Xiangqian was stunned for a moment. "Agreement? Uncle Yi, if you have any request, just let us know. We will fully cooperate."

Yi Zhonghai smiled and said, "It's not a big deal. I hope that in this cooperation, I can put some of my research results into practice. I also hope that you can carefully record every step and result, which will be very helpful for my future research."

After hearing this, Li Xiangqian was excited. "Uncle Yi, this is great. We can definitely do it! With your guidance, we can definitely make this piece of farmland a model."

After the two reached an agreement, Yi Zhonghai came to the courtyard the next day and began a detailed survey of the farmland. He brought professional soil testing equipment, personally sampled and analyzed the soil composition, and determined the specific problems of the soil and improvement plans.

"Move forward," Yi Zhonghai said as he checked the soil. "The main problem with your soil is the imbalance of pH and nutrient distribution. We need to adjust the pH value of the soil and increase the organic matter content."

Li Xiangqian listened carefully and wrote down the key points, "Uncle Yi, how do we do it specifically?"

Yi Zhonghai smiled and pointed out, "First, we need to apply lime to adjust the pH of the soil, and then apply well-rotted organic fertilizer to increase the organic matter in the soil. In addition, we can also plant some green manure crops, such as alfalfa, which can not only improve the soil, but also increase soil fertility."

Li Xiangqian nodded, "I understand, Uncle Yi, I will lead everyone to follow your method step by step."

In the next few days, the courtyard was busy. Li Xiangqian and his neighbors began to apply lime and organic fertilizer, and each step was carried out strictly according to Yi Zhonghai's instructions. Yi Zhonghai also came to check the progress from time to time and gave on-site guidance.

One evening, Li Xiangqian and Yi Zhonghai stood by the farmland, looking at the gradually fertile land, feeling a sense of accomplishment. Yi Zhonghai said with satisfaction, "Xiangqian, you have done a good job. Next, we need to observe and adjust for a period of time to see how the soil changes."

Li Xiangqian nodded, "Okay, Uncle Yi, we will definitely record every change carefully."

As time went by, the efforts of Li Xiangqian and his neighbors gradually paid off. The pH value of the soil began to balance, and the growth of crops improved significantly. The courtyard was filled with a joyful atmosphere, and everyone's face was filled with satisfied smiles.

On a sunny morning, Li Xiangqian was checking the crops when Yi Zhonghai came over and said, "Xiangqian, I have a new idea. We can try to introduce some new varieties of high-yield crops to this land. This will not only increase the yield, but also increase the diversity."

Li Xiangqian's eyes lit up, "Uncle Yi, this is a great idea, we can definitely give it a try."
