Siheyuan, integrating everything, cultivating the city

The potato fields that were once full of life have now shriveled up due to pests. Although he has tried his best to take various measures, the state of the potato seedlings still makes him anxious. In particular, several leaves have begun to turn yellow and wither, which makes him even more worried.

"If these potatoes continue like this, they may be completely ruined." Li Xiangqian thought silently in his heart. The uneasiness in his heart was like a cold vine clinging to his heart, making him suffocate.

He squatted down and carefully checked the roots of the potato seedlings, and found that some abnormal changes had occurred in the soil. The soil became loose, and some places even showed signs of root rot. Li Xiangqian felt more and more depressed. He knew that this disease might be caused by the continuous invasion of pests and water pollution. In any case, he couldn't just watch these potatoes being wiped out. He needed to find a way to save them and give the potato seedlings a glimmer of hope.

"We must find a way," Li Xiangqian secretly made up his mind. He decided to take immediate action to find a solution that could effectively fight potato diseases.

He went to the study room in the courtyard and flipped through some agricultural books he had collected, trying to find inspiration to solve the problem. In the ocean of books, he searched for relevant information about potato diseases, but his heart was always filled with anxiety. Every time he turned a page, he hoped to find a solution to the problem, but every time he saw those complicated professional terms and treatment methods, he couldn't help feeling a little powerless.

"This information seems too complicated." Li Xiangqian laughed at himself, "Maybe I still need help from professionals."

He decided to contact Professor Zhang and ask for help again. His heartbeat quickened the moment he dialed the phone. Although he had communicated with Professor Zhang more than once, Li Xiangqian could not help but feel an urgency every time he faced a problem.

"Professor Zhang, my potato seedlings have a serious disease problem." Li Xiangqian's voice was a little nervous. "I have taken many measures, but the situation does not seem to be getting better."

Professor Zhang was silent for a moment after listening to Li Xiangqian's description. Then he said in a serious tone: "The potato disease problem is indeed complicated. You first need to check the soil condition to see if there are root rot bacteria. Secondly, you also need to understand whether other plant diseases have spread to the potato seedlings."

"Okay, I'll check it right away." Li Xiangqian replied. Although he felt a little uneasy, he still remained calm.

After hanging up the phone, Li Xiangqian returned to the field and began to carefully check the soil. He dug the soil with a hand shovel and found that some roots had turned black and rotten, and the root system had become fragile. These signs of disease made him feel heartbroken.

"It seems that the problem is more serious than I thought." Li Xiangqian sighed in his heart, "We must find a solution as soon as possible."

He decided to take more radical measures, first to deal with the germs in the soil, and then to treat the potato seedlings with special agents. He found some pesticides and soil conditioners and prepared to thoroughly disinfect and improve the potato field. The whole process was very tedious, and he needed to handle every detail carefully to ensure that every step was effective in fighting the disease.

While dealing with the potato fields, Li Xiangqian's heart was filled with mixed emotions. He knew he had done his best, but the unknown outcome still made him nervous and uneasy. He often sat by the field, staring at the damaged potato seedlings, praying in his heart, hoping to reverse the current predicament.

"I must not give up," Li Xiangqian said to himself, "even if I face great difficulties, I must persevere to the end."

Time passed quietly in the busyness and anxiety. Li Xiangqian spent a long time in the fields every day, observing the changes in the potato seedlings and constantly adjusting the treatment plan. He gradually felt tired from the day-to-day work, but he never stopped caring for and taking care of the potato seedlings. Whenever he saw the potato seedlings show some signs of recovery, a glimmer of hope would rise in his heart.

One evening, Li Xiangqian found that the condition of the potato seedlings had improved a little. Although some seedlings were still affected, overall, the growth of the potato seedlings was much better than before. His worries were slightly relieved, but the pressure in his heart still existed.

"These changes are a good start, but they are still far from ideal," Li Xiangqian thought silently in his heart, "I must continue to work hard until the problem is completely solved."

He continued to check the potato fields regularly to ensure that every potato seedling was adequately cared for. He also regularly recorded the growth of the potato seedlings, trying to find more improvement solutions through data analysis. In this process, Li Xiangqian not only learned how to deal with potato diseases, but also gradually mastered more agricultural knowledge and skills.

Despite the heavy workload, Li Xiangqian's mentality gradually became more positive. He began to learn to find fun in his busy work and enjoy every time the plants recover and grow. Every time he sees the potato seedlings gradually recover, his heart is filled with a sense of accomplishment and satisfaction.

One day, while working in the fields, Li Xiangqian found a particularly healthy potato seedling. The seedling's green leaves and upright stems formed a sharp contrast with the other seedlings. Seeing such a change, he felt extremely relieved.

"This is the result of our hard work," Li Xiangqian said proudly. "Although we faced many challenges, we were able to achieve some results in the end."

As time went by, Li Xiangqian's treatment of the potato field gradually showed results. The condition of the potato seedlings began to improve, which relieved his tension a little. However, he knew that although the current situation had improved, potential threats still existed. He realized that in addition to dealing with existing diseases, he must also strengthen pest control to prevent similar problems from occurring again in the future.

At this time, Li Xiangqian thought of a solution to the problem - to invite more manpower to help catch pests. His neighbor He Yuzhu was a kind-hearted person who also had a certain understanding of agriculture. Li Xiangqian decided to ask He Yuzhu for help, hoping to use his strength to completely eliminate the pests in the fields.

So Li Xiangqian walked towards He Yuzhu's home. He Yuzhu's home was not far from Li Xiangqian's courtyard. It was a traditional bungalow with several tall fruit trees planted in the front yard. Li Xiangqian walked to the front of the yard and knocked gently on the door.
