“Go and call Mr. Song, and I go to the port of Jinmen with me to raise funds for this fleet.”Li Yu ordered that although the things brought back by the fleet were inconspicuous, he knew the power of this thing, and Song Yingxing was the one who could maximize the role of this thing, so he should be seen in the first time.

"Dare to ask your majesty, what treasure is this fleet brought back?"Wang Chengen is now more familiar with Li You, he knows that asking this kind of thing will not cause the emperor's suspicion, and he is indeed somewhat curious, before Chen Guangfu's fleet from the Aoguang returned a large number of gold when his majesty was so excited?Is it the fairy medicine that can be found from overseas Xian Island, which can make people immortal?But shouldn’t that be accompanied by Mr. Fushan?How to choose Song Yingxing.

Surely, it is a treasure, and when you see it, you will know it.Li You did not want to disclose, not often Song Yingxing was taken to the palace, Li You immediately led the people to leave to Jinmen, this move also caused a lot of speculation, they and Wang Chengen are as curious as, what is the fleet brought back?

However, when this thing appeared in front of Wang Chengen and others, they were greatly disappointed, only to see that such a thing seemed inconspicuous, like a piece of white, yellow or brown earth, but also emit all kinds of odors, does not look like a treasure.

But Song Yingxing and Li You are happy, Song Yingxing took a small piece of crushed and put it in his own observation, "Your Majesty, this is what you call guano stone?"

“It is precisely that this thing, after the accumulation of feces and corpses of birds, bats and seals, has evolved over a long period of time, which, if it is scattered in the field, will greatly increase the yield of the farmland; of course, how to add it, and how much, requires that Mr. Song to study carefully, and once the role of the object is excavated, the people of my Ming can stay away from hunger.”Li You said that the main sources of guano stone are the islands along the coast of Peru and Baja California, as well as the large number of cormorants, psalms and pond geese in Africa, and are also distributed on some islands in Southeast Asia, and the guano stone is rich in nutrients such as nitrogen, phosphate and potassium, which can greatly promote land production.

“Of course, in addition to studying these, Mr. Song should also analyze what makes this guano stone so useful.”Now can try to excavate guano stone to act as fertilizer, but these natural guano stone will always run out one day, and the distribution of guano stone is mostly remote, can only take care of the nearby fields, want to let the entire Daming people enjoy this welfare, but also have to study synthetic fertilizer, of course, this requires a long process, but do some preparation in advance is always good, there will always be time to use in the future.

“This is a great merit, and the micro-supling will do its best to do this.”Song Yingxing said that the casket valley pile agricultural production is very important, Song Yingxing remembered that Li You once described a good prospect for him, he felt that these guano stones are really more precious than gold, gold this thing is hungry and can not eat, cold can not wear, but this bird dung stone can bring more food to the people of Daming, so that more people away from the suffering of hunger, but much more useful.

Immediately, the guano stone carried by this fleet was all unloaded and transported to the field farm in charge of Song Yingxing on the outskirts of Beijing, and Song Yingxing immediately led the team to carefully study the role of guano stone, and soon made progress, summarizing the most reasonable amount of guano stone, and the increase in the yield of various crops after the use of guano stone, providing valuable reference data for the large-scale promotion of guano stone.

Several major factors that determine grain production are soil, climate, temperature, seeds, farming methods, etc., of which climate and temperature are uncontrollable, but the other few can be adjusted, now it is a small ice age, the temperature is greatly reduced, the grain production in Daming is declining, although Li You let Song Yingxing presided over the promotion of potatoes, sweet potatoes and corn brought back from the North American continent, but this still can not meet the needs of the people of Daming.

Buying food from all over the South China is not a long-term solution, but also can only take care of some coastal states and counties, and whether it is the North American continent or Australia's development is not an overnight thing, in the future for a long time, Daming is still the main area of people's lives, then the use of guano to increase the production of food has become the best choice.

Of course, the guano stone is not all good, if the same land can produce more food is a good thing, but this will also bring about the increase in population, a large number of feces by the landlords and many other problems, but this is good for promoting urbanization and industrialization and expanding the North American continent and Australia, only these people can be separated from the land, can provide more labor to the workshop, so that more people to participate in the expansion of the North American continent.

“Sire, after the study of micro-chung and other students in the Faculty of Agriculture, this guano stone can indeed increase the yield of food, and the specific data are here.”Saying that Song Yingxing handed over a form, the above detailed list of the use of different amounts of guano stone to improve the yield of rice, wheat, potatoes, corn and other crops.

"Well, Mr. Song has worked hard, and since the accurate figures have been obtained, then continue to expand the scope of promotion, and then let the agricultural colleges around the country also participate in this matter, once it is determined that the guano stone does indeed promote their local food production, it will immediately promote, I will let the merchants in the south transport more guano stone back."Lee ordered.

“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 role, and then the manufacture of new farming machinery, the cultivation of good seeds and so on has increased food production, and now coupled with this guano stone, Song Yingxing has not much to worry about the problem of food.

"But there is still one thing to be shown by His Majesty, and the name of this tungstone sounds indecent after all, and it is quite contrary to the efficacy of this thing, and His Majesty is asked to give it a name."Song asked for the star.

“This...it’s better to call it a thorn.”The name is loud enough, isn’t it?
