Wen Tianxiang was willing to eradicate the tragedy of women drinking porridge. Considering the current difficulties, it was not suitable for the times. He said: "Your Majesty, I think that things are urgent and serious. Nowadays, he should take the fight against Mongolia as the top priority..." Li Jun shook his hand to stop Wen Tianxiang and continued, saying: "Increasing taxes does not necessarily depend on increasing tax rates. There are other methods to use. Increasing grain output is the fundamental way to solve the problem."

After studying Chinese history in depth, Li Jun said a thought-provoking sentence: "The so-called benevolent monarchs in all dynasties gave the people only tax reduction and exemption, saving some benefits to the people, as if tax reduction is a magic pill. This is like a small-sized pancake that is enough to divide. The country is full and the people are hungry; the people are full and the country is poor again, and it is always so contradictory and seems irreconcilable. In fact, the fundamental way to solve this problem lies in paying attention to science and technology, promoting education, developing production, improving production efficiency, and creating a large amount of material wealth. Then a strong country and rich people are a natural thing."

As Li Jun said, not only Chinese history is like this, but the entire world history is like this. When encountering a good monarch and implementing a policy of light taxes and low taxes, the people will gain some benefits. If they meet a bad monarch at the wrong time, not to mention excessive taxes, they will add a little tax, which will make the insufficient material wealth created because of low production efficiency, and the people will have to struggle in dire straits.

Someone will rise up, silence the people and punish them, and save the people from dire straits. When they succeed, they will repeat the mistakes that the people they overthrown have made and squeeze the people. This will form a vicious circle: poverty, poverty, no matter how poor, it is extremely poor from life to death.

Li Jun was filled with emotion and agreed with China's strategy of "Science and Education to Prosper the Country". He thought that he could choose some technologies suitable for the conditions of the time from modern technology to promote it, make the cake bigger, so that the country and the people can have food, and no longer have conflicts or even wars because of the competition for food.

It is certainly good to increase grain output. Wen Tianxiang and the others dreamed that given the technological level at that time, it could only be a beautiful dream. Throughout the dynasties, a lot of investment in agriculture had been invested in, and the results were very little. When Li Jun mentioned this nerve-wracking thing, Wen Tianxiang and the others' heads suddenly became much bigger.

Li Jun understood their thoughts, smiled slightly, and said, "In addition to firing cement, the cement kiln I drew can also produce silicon fertilizers. Combined with corrosive soil and farm fertilizers, it can increase the output by 10 to 40%. The production and use of silicon fertilizers must be fully promoted in the Song Dynasty. Well, first promote it in places with conditions, and then it will be implemented nationwide when the conditions are ripe."

The fertilizers of crops are mainly nitrogen, phosphorus and potassium. Modern research shows that the use of chemical fertilizers can increase the yield by 40 to 50%. Nitrogen fertilizer is the main fertilizer. The chemical production process is too complex and cannot be endured by the Southern Song Dynasty's scientific and industrial level. The production of nitrogen fertilizer is as far away as the human dream of flying in the sky, and cannot be reached.

The production of phosphorus fertilizers requires the use of sulfuric acid and corrosion-resistant materials, which was something that the industrial level of the Southern Song Dynasty could not bear.

The process of potassium fertilizer is simpler and cannot be produced in a hurry. Only silicon fertilizers containing multiple elements can be produced without modifying the cement kiln. Although the effect is not as obvious as the three chemical fertilizers of nitrogen, phosphorus and potassium, it is also a good choice.

There are many small cement factories in our country, and the cement produced does not have much market competitiveness. In order to promote the conversion and efficiency of small cement factories, a silicon fertilizer project was once implemented. Li Jun knew about it. After thinking about it, he decided to produce this useful fertilizer.

The production of silicon fertilizer was promoted well under the promotion of Li Jun, and achieved good results. The grain output was greatly improved. The historical tragedy of women drinking porridge for life was eradicated and Li Jun's great wish was fulfilled. (Note: The main raw materials of silicon fertilizer are lime matter raw materials and clay raw materials, and the fuel is coal. They must be crushed into pellets before feeding and after firing. At that time, there was no crushing equipment. After Li Jun considered it, he designed a set of crushing machinery using animal power and hydraulic power based on actual conditions. The effect was much worse than the current crushing equipment. At that time, it was an amazing invention. What was more important was that it could complete the crushing task, which was just a longer time. Using 50~125Kg of silicon fertilizer per mu can increase the yield by 8%~35%.)

Wen Tianxiang and the others could never have imagined that they could increase such a large amount of output, and they all showed a surprised expression of Mo Ming. This cannot be blamed on Wen Tianxiang, it is really a bit incredible for Li Jun's idea. Li Jun's promotion of silicon fertilizer was the earliest major event in history to use chemical fertilizers, six hundred years earlier than Europe.

Just when Wen Tianxiang and the others were shocked, Li Jun said something that made them jump up in surprise.

After saying so many things, it was even more tiring than giving a lecture. Li Jun picked up the tea cup and took a sip of tea, and then said: "The second most effective way to improve grain is to improve rice varieties and promote hybrid rice."

Wen Tianxiang and his friends had no idea what hybrid rice was, and their minds were blank and they didn't know at all. After they had been in contact with Li Jun for a long time, they discovered that Li Jun had many novel, bold, and very applicable ideas and creations, which were really as far as the sea, and were unfathomable. They all stared at Li Jun with wide eyes and listened to his explanation.

Even Master Mingxia, who was not surprised by his favor and disgrace, was surprised and looked at Li Jun with his "fair eyes" wide.

Li Jun was not surprised at all about their performance. He, a person from a thousand years later, had the most common things in that era and shocking effects in the Southern Song Dynasty. Li Jun saw it a lot, and it was no wonder.

"Hybrid rice can greatly increase grain yield, but there is a difficulty at present, which is to find wild fruit and cultivate rice seeds. Hybrid rice has a high yield per mu, and its disadvantages are also obvious. It is that it cannot produce seeds by itself, and can only use the first generation of seeds. It must be made every year and every season." Li Jun confirmed the conclusion: "This disadvantage is nothing compared to the yield per mu of thousands of kilograms. It is like a small flaw in white jade, which is not worth mentioning." He thought to himself: "Old Yuan, I plagiarized your achievements. If you say bad things about you, I will be too sorry for you. Hehe, if you are angry, just dance your tap dance on the ridge of the field, don't sprain your feet."

Now, the yield per mu of China's super hybrid rice in the experimental fields has reached 1,200 kilograms, and the yield per mu of thousands of kilograms is already very low. However, it was unimaginable in the Southern Song Dynasty. Wen Tianxiang, a person who was still in shock, couldn't help but jump up, overturned the teacup, smashed it on the ground, and stuttered for a long time before saying, "Master, is this true?" It was so surprising that he could not help but question the monarch so much that he couldn't help it.

Chen Yizhong, Zhao Liangchun, Gundam, Lu Xiufu and Master Mingxia all stood up suddenly and looked at Li Jun with incredible eyes.

"Sit down, sit down, sit down." Li Jun was not surprised at all about their reaction, saying: "The yield of acre of over a thousand kilograms is relatively low. If we do well, the yield of acre is higher than that, two thousand kilograms will not be difficult."
