Chapter 538 The land in Jinnan is saline-alkali land Lin Che analyzed the shortcomings of Zhu Yuanzhang's previous decisions and practices one by one, and explained the issues clearly and logically in calm and objective language. Slowly, people began to accept Lin Che's explanation, and began to think about their own blind spots in the past. They began to have doubts about Zhu Yuanzhang's leadership ability, and at the same time they also had a glimmer of hope for Lin Che. They needed to re-examine the problem and find the true truth. Effective solution. Then they began to discuss how to adjust and change in the future to continue to solve the problem of land waste in Jinnan, instead of blindly pursuing the wrong ideas of the past. Lin Che became the new focus, and people were eager to get more guidance from him. For a moment, all the courtiers looked at Lin Che intently, to see how he would tell the real problem of the land waste in Jinnan. As Lin Che revealed the answer, everyone was immediately shocked. They just thought that the land was not fertile and it would be difficult to grow crops. However, they did not know that the land in Jinnan was not just barren, but saline-alkali land. As Lin Che continued to explain: "The land in Jinnan is very special. It is not suitable for farming. Most of the land is saline-alkali land, making it impossible to grow crops. Even if it barely survives, the yield will be minimal." "The real reason why the land in Jinnan is abandoned is that the land here is all saline-alkali land." Zhu Yuanzhang, Liu Sanwu and Fu Youwen fell into silence for a while. They were not very familiar with the word saline-alkali land. They exchanged glances with each other, and their expressions of bewilderment turned on their faces. Seeing everyone's confusion, Lin Che smiled slightly: "The so-called saline-alkali land means that the soil contains too much salt and alkaline substances, causing the land to lose conditions suitable for plant growth. It is a sterile soil type. It’s almost impossible to grow crops on such land.”

After everyone heard this, they suddenly understood. They began to understand why the cultivated land in the Jinnan area had not been effectively used, and why the crop masters were sparse and thin, unable to produce a bumper harvest. A hint of helplessness flashed across Zhu Yuanzhang's face. He realized the complexity of this problem. However, for a person who regarded the development of Jinnan region as a major factor, no difficulty was insurmountable. He took a deep breath and firmly Said: “Since the root of the problem lies in land salinization, we must find ways to solve this problem.” After hearing this, Liu Sanwu and Fu Youwen focused their attention on Lin Che again, and he slowly said: "The improvement of saline-alkali land requires a series of measures. First, we can introduce fresh water for flushing to flush out the salt in the soil. , Secondly, increase the application of organic fertilizers and amendments to improve the nutrient content and water retention capacity of the soil. Finally, select suitable crops and salt-alkali resistant varieties for planting to gradually restore the productivity of the land. " Lin Che's words were full of confidence and hope. He continued: “To solve the problem of land waste in Jinnan, we need to carry out rice breeding and cultivate excellent varieties that are suitable for saline-alkali soil. This process is very time-consuming and labor-intensive and requires us to conduct a lot of experiments and research to find the most suitable for this land. of rice varieties.” "In addition to rice breeding, we also need to start improving the degree of salinization of the land. This is a more difficult task that requires the comprehensive application of knowledge from multiple fields such as science, agriculture and environmental protection. We have to use irrigation, diversion, and fertilization. and other means to gradually reduce the salt content in the soil and gradually restore the fertility of the land.” In order to further answer everyone's doubts, Lin Che continued to explain to everyone: "In fact, I have specifically visited the land of Jinnan for inspection and research. I have an in-depth understanding of the soil composition, water conditions, climate characteristics, etc., and thus accumulated a lot of knowledge. There is a lot of knowledge about the land in Jinnan. Although I am not a farmer, I have never stopped paying attention to the land. I believe that through everyone’s efforts, we will be able to solve the land problem in Jinnan.” The next day in the court. Prince Zhu Biao took out a map and relayed it to the ministers based on Lin Che's explanation: "The land in the Jinnan area of ​​the imperial court suffers from serious salinization problems. The land here looks like it has been soaked in pickle water and cannot be cultivated. Over time, the salt and alkali seep into the depths of the soil, making it impossible for plants to absorb it normally. Water and nutrients, this is like taking in too much salt in our body, causing edema and malnutrition.” "Land salinization is mainly caused by two factors. One is that the salt content in the groundwater is too high, and the other is poor soil drainage. These salts penetrate into the soil surface through water, and become thicker and thicker due to evaporation, eventually forming a It is impossible to cultivate and survive in the dead saline-alkali zone," Zhu Biao continued to explain. Liu Zhen, the minister of Dali Temple, frowned: "Your Highness, King Qin, the problem of salinization in Jinnan is so serious, why has the imperial court not taken any measures for so long?" Zhu Biao smiled and replied: "Even if your father knew about this, he would not be able to find a solution for the time being. The complexity of the salinization problem is self-evident. It requires comprehensive consideration of multiple factors such as groundwater systems, soil drainage, and the adaptability of crop planting. Your father has specially summoned all the ministers, hoping that everyone can discuss solutions together." Censor Li Xian couldn't help but interjected: "What His Royal Highness the Crown Prince said is absolutely true. This matter is indeed a difficult problem. However, ministers should adopt different countermeasures in order to be effective." Zhu Biao nodded in praise: "What Li Xian said is that the causes and degrees of salinization in different areas are different, so the countermeasures taken should also be adapted to local conditions. You can first improve the drainage system so that the groundwater can be drained smoothly, thereby reducing the salt content. Secondly, crops adapted to grow in saline-alkali soil can be introduced to improve land utilization. " The ministers nodded displeasedly upon hearing this. They seemed to be full of confidence in solving this problem. Zhu Biao continued to expand his views, explaining some technical methods and agricultural farming experiences that have been successfully applied in other countries. As Zhu Biao explained, the ministers became increasingly aware of the importance and urgency of solving the problem of land salinization. They thought that although they were civil servants, they could not ignore practical issues related to the stability of the country and the well-being of the people. There was a discussion in the court, and they began to discuss possible solutions to the problem of land salinization. Everyone hopes to contribute to the future of the country. The situation was urgent, and Zhu Yuanzhang eagerly urged the ministers to resolve the issue quickly. He firmly believed that with the gathering of many ingenuity, he would eventually be able to find an effective solution to the Tianjin-nan problem.

After a long period of discussion and research, the imperial court finally formulated a solution with unknown effects. (End of this chapter)
