"Go and call Mr. Song, and go with me to the port of Jinmen to raise funds for this fleet. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info" Li You commanded, although the thing brought back by the fleet this time is inconspicuous, he knows the power of this thing, and Song Yingxing is the one who can maximize the role of this thing, so he should be allowed to see it as soon as possible.

"Dare to ask Your Majesty, what kind of treasure did this fleet bring back?" Wang Chengen is now more familiar with Li You, he knows that asking about this kind of thing will not arouse the emperor's suspicion, and at the same time, he is indeed a little curious, when Chen Guangfu's fleet transported a large amount of gold from the Wa Kingdom in the past, he didn't see His Majesty so excited? Could it be that the elixir found from overseas fairy islands can make people immortal? But shouldn't Mr. Fu Shan accompany him? How could you choose Song Yingxing.

"Haha, it's indeed a treasure, you'll know when you see it." Li You didn't want to leak it, and soon Song Yingxing was taken to the palace, and Li You immediately led the men and horses to rush to Jinmen, which also caused many important ministers in the court to speculate, they were as curious as Wang Chengen, what did the fleet bring back this time?

However, when this thing appeared in front of Wang Chengen and the others, they were greatly disappointed, only to see that such a thing looked inconspicuous at all, like a piece of white, pale yellow or brown clods, and it also exuded all kinds of peculiar smells, and it didn't look like a treasure at all.

But Song Yingxing and Li You were overjoyed, Song Yingxing took a small piece and crushed it and put it in his hand to observe, "Your Majesty, this is what you call struvite stone?" ”

"It is this thing, which has evolved over a long period of time from the accumulation of feces and carcasses of birds, bats and seals, and if it is scattered in the field, it will greatly increase the yield of the field; Of course, how to add it, and how much to add, these need to be carefully studied by Mr. Song, once the effect of this thing is excavated, then the people of my Ming Dynasty can stay away from hunger. Li You said that struvite is mainly produced in the islands off the coast of Peru and Baja California, as well as in areas in Africa where cormorants, pelicans and gannets are abundantly populated, and is also distributed on some islands in Southeast Asia.

"Of course, in addition to studying these, Mr. Song should also analyze what makes this struvite so useful." Now you can try to dig struvite to act as fertilizer, but these natural struvite will always be used up one day, and the distribution of struvite is mostly remote, can only take care of the nearby fields, want to let the entire people of the Ming Dynasty enjoy this welfare, but also have to research synthetic fertilizers, of course, this takes a long process, but it is always good to make some preparations in advance, and there will always be a time to be able to use in the future.

"Wechen obeys the order, this is a great merit, Wechen will do his best to do this well." Song Yingxing replied, the chatterbox and grain pile agricultural production are very important, Song Yingxing remembered that Li You had described the bright prospects to him, and felt that these struvite stones were really more precious than gold, gold This thing can't be eaten when you're hungry, and you can't wear it when it's cold, but this struvite can bring more food to the people of the Ming Dynasty, so that more people can stay away from the pain of hunger, but it's much more useful.

Immediately, all the struvite carried by this fleet was unloaded and transported to the grange supervised by Song Yingxing on the outskirts of the capital, Song Yingxing immediately led the team to conduct a careful study on the role of struvite, and soon made progress, summed up the most reasonable amount of struvite, as well as the increase in the yield of various crops after the use of struvite, which provided valuable reference data for the large-scale promotion of struvite application.

Several major factors that determine grain production are soil, climate, temperature, seeds, cultivation methods, etc., of which climate and temperature can not be controlled, but several other items can be adjusted, now it is the Xiaoice period, the temperature has dropped greatly, and the grain production in Daming is declining, although Li You asked Song Yingxing to preside over the promotion of potatoes, sweet potatoes and corn brought back from the North American continent, but this still cannot meet the needs of the people of Daming.

After all, it is not a long-term solution to buy grain from all over the South Seas, and it can only take care of some coastal states and counties, and whether it is the North American continent or the development of Australia is not an overnight thing, for a long time in the future, the Ming Dynasty is still the main area where the people live, so the use of struvite to increase the production of grain has become the best choice.

Of course, struvite is not all good, if this thing is spread, the same land can produce more food, although it will also bring many problems such as population increase, a large number of tenants are fired by landlords, etc., but it is good for promoting urbanization and industrialization, and expanding the North American continent and Australia, only by stripping these people from the land can more labor be provided to the workshops and more people to participate in the expansion of the North American continent.

"Your Majesty, after the research of Weichen and other students and professors in the Agricultural College, this struvite can indeed increase the production of grain, and the specific increase data is here." After that, Song Yingxing handed over a table detailing the yield improvement data of rice, wheat, potatoes, corn and other crops using different amounts of struvite.

"Well, Mr. Song has worked hard, now that we have an accurate figure, then continue to expand the scope of promotion, and then let the agricultural colleges in various places also participate in this matter, once it is determined that struvite does also have a role in promoting their local food production, I will immediately promote it, and I will also let the merchants in the south transport more struvite back." Li You commanded.

"Weichen obeys the order, with such a treasure, my food problem can be greatly alleviated." Song Yingxing said excitedly that the previous promotion of corn, potatoes, sweet potatoes and other crops has played a certain role, and then the manufacture of new farming machinery, the cultivation of improved seeds, etc., have increased grain production, and now with this struvite stone, Song Yingxing is no longer worried about the problem of food.

"It's just that there is still one thing that needs to be revealed by Your Majesty, the name of this struvite stone sounds a little indecent after all, and it really doesn't match the effect of this thing, and I ask Your Majesty to give this thing a name." Song Yingxing pleaded.

"This ...... It's better to call it Jin Kela. "That name should be loud enough, right?
