Siheyuan, integrating everything, cultivating the city

After hearing this, Xu Damao smiled with relief: "That's great. It seems that we can work together, learn from each other, and find the most suitable planting method."

Li Xiangqian nodded with satisfaction: "That's right. I believe that only by working together and sharing experiences can we achieve the best results."

As time went by, the technical exchange meeting entered the practical operation stage. Li Xiangqian took everyone to his own vegetable field, demonstrated how to use the new fertilizer on the spot, and guided everyone to carry out the actual operation. His detailed explanation and demonstration benefited everyone a lot.

Zhang Mei watched from the sidelines, feeling proud and gratified. She knew that Li Xiangqian had not only made progress in technology, but also showed great enthusiasm and patience in sharing and helping others. This spirit not only made her proud, but also gave her confidence in her future work.

After the exchange meeting, everyone expressed their gratitude. Xu Damao patted Li Xiangqian on the shoulder with a sincere smile in his eyes: "Xiangqian, today's sharing is really helpful. We will seriously try the methods you taught us."

Li Xiangqian smiled, feeling satisfied. "I am very happy with everyone's feedback. I hope we can all improve our planting level through these new technologies and strive to achieve good results in the bet."

In the following days, the vegetable fields in the courtyard were full of enthusiasm and vitality. Li Xiangqian's sharing and the introduction of new technologies made everyone's planting work more scientific and effective. Everyone worked hard to put what they learned into practice, and the harvest of the vegetable fields gradually showed a significant improvement.

Li Xiangqian felt a strong sense of accomplishment during this period. He not only saw the results of his own efforts, but also saw the positive changes in everyone's learning and progress. He knew that success is not only based on personal efforts, but also on collective cooperation and common progress.

At first, Li Xiangqian only noticed a few small holes on the leaves. He thought it was the wind and didn't pay much attention to it. However, a few days later, he found that the holes were getting bigger and bigger, and the leaves began to shrink. The vitality of the whole vegetable garden seemed to be hollowed out. Li Xiangqian began to realize that this was not just a problem with the wind.

He carefully examined each plant and found tiny insects hiding on the underside of the leaves, which were tiny but caused great damage to the plants. These insects were dense and large, like ants, and they were so numerous that he was upset. He began to try various methods to get rid of these pests: he sprayed the plants with homemade fertilizers and natural insect repellents, and used fine nets to isolate the affected areas. He also consulted the elders in the village and learned many traditional solutions, but none of them seemed to solve the problem fundamentally.

As time went on, Li Xiangqian discovered that these pests were not just staying in the vegetable garden, they seemed to have begun to spread to other corners of the yard. His flower beds, lawns, and even around his carefully arranged small pond showed signs of pests. The entire courtyard ecosystem began to be threatened, and Li Xiangqian felt unprecedented anxiety and frustration.

He began to work in the garden more frequently, hoping to find a more effective way to deal with this disaster. He often stayed up all night to carefully observe the changes in every inch of land. Once, he found a different sign: there was an unusually active insect next to some plants. Its appearance was different from other pests, and its color was brighter, as if showing off its presence.

Li Xiangqian decided to track the insect. He patiently observed its movements and found that it always seemed to gather on certain plants. Gradually, he realized that this insect might not be an ordinary pest. It seemed to have some special influence that could attract other pests. Li Xiangqian began to suspect that this disaster was not just a problem of pests, but might involve some more complex ecological relationship.

In the following days, Li Xiangqian's research became more and more in-depth. He began to consult books on plant diseases and insect ecology and contacted some experts, hoping to find clues to the solution. At the same time, he also carried out a series of experiments inside and outside the courtyard, trying different solutions to deal with the infestation of pests.

As his efforts deepened, Li Xiangqian began to discover some subtle connections between different plants and pests. The smell of certain plants seemed to attract specific insects, which in turn might affect the health of other plants. He began to try to adjust the layout of plants and change the cultivation pattern of the vegetable garden, hoping to break the chain of transmission of pests.

In Li Xiangqian's courtyard, the flowing water has always been his most relaxing place. He likes to sit by the pond, listen to the sound of the gurgling water, and feel the breeze on his face. Now, this place has become disturbing. Several pieces of plant debris eroded by insect pests float on the surface of the pond. Li Xiangqian stands by the flowing water with a dim look in his eyes, and his fingers unconsciously touch the stones by the water.

He looked at the running water, his heart filled with anxiety and uneasiness. Those pests seemed to be not only an invasion of plants, but also an invasion of his inner peace. Every time he stood by the running water, he tried to find a kind of comfort, but found that the anxiety in his heart was like ripples in the water, which could not be calmed down no matter what. His thoughts were brought to many past events, and the fragments of memory were intertwined with the current predicament. He remembered that when he first moved into the courtyard, everything here was so beautiful and peaceful. Those green plants and clear pool water were all what he loved.

"Uncle Li, are you here again?" A familiar voice broke his contemplation. It was Li Xiangqian's nephew Xiao Ming, a lively young man who always had a smile on his face. Xiao Ming was holding a small basket filled with freshly picked vegetables.

"Well, Xiao Ming, here I am." Li Xiangqian forced a smile, trying to hide his worry.

"Xiao Ming, how come you have time to come here today? Is there something?" Li Xiangqian asked, turning to look at Xiao Ming. The feeling of powerlessness in his heart was suppressed even more deeply, but he knew that he needed to stay calm in front of his nephew.

"I heard that you've been worried about your vegetable garden lately, so I came to take a look." Xiao Ming put the basket on the ground and looked at Li Xiangqian with concern. "I've also heard about the pest problem you mentioned in the village, and I want to know how you're doing now."

Li Xiangqian sighed and rubbed his temples. "These pests are really troublesome. Although I have tried many methods, it seems that I can't get rid of them completely. Now their influence has spread to the entire courtyard, and even the plants around the pond are beginning to have problems."
