Chapter 172: Li Zhen's efforts The number two person in the Tang Empire, the crown prince of the dynasty whose status is second only to the monarch, the future heir of the Tang Empire, and the commander-in-chief of the Southern Army of the Tang Dynasty......
Wait, wait, Li Zhen's many identities made Sai Qunxiong understand that Li Zhen is the real super golden thigh, and Wang Dewei, who he thought was a thigh before, can only be regarded as an insignificant hair on this golden thigh - Wang Dewei is just the helmsman of a super shipyard, while Li Zhen is the future prince of the Tang Dynasty, holding hundreds of thousands of troops, conquering countless countries and lands, and countless kings of small countries groveling in front of him, kissing his boots......
Such golden thighs, if you don't hold them at this time, when will you stay?
So as soon as he heard Li Zhen's question, Sai Qunxiong immediately took out all the things he brought: "This is all the things we brought from our hometown, I hope there are things that can be useful to your esteemed Highness." ” "Your Highness, this is the kind of delicious food that my subordinates just said."
Wang Dewei stepped forward, opened one of the bags, and took out a fist-sized thing with a reddish-brown skin that looked quite unbearable and introduced: "Don't look at this thing, it doesn't look very good, but it tastes crisp and delicious, and more importantly, the skin of this thing is very thin, and all the inside is edible......
Your Highness, if this thing can be successfully planted in Datang, then we will have one more crop that can be eaten in Datang. ” Wang Dewei introduced it in detail, but Li Zhen didn't listen to a word - in terms of understanding sweet potatoes, Wang Dewei is only a native of the Tang Dynasty, how can he compare to Li Zhen, a time-traveler who has traveled from the future?
You must know that although Li Zhen is a little rich second generation, his family started after he was ten years old, and his family was not very rich when he was ten years old, and he didn't eat this thing in the countryside back then.
"Sure enough, this is the sweet potato......
Hahaha......"
Li Zhen was so excited that she laughed out loud at the end.
I can't help but laugh, God knows how much effort he made to increase crop yield after coming to Datang - Li Zhen asked for a huge manor from Li Shimin back then, although in the end a place became a cement test workshop, but a large part of it was still grown grain, the purpose was to study how to increase grain production, and even not only Li Zhen, even Li Zhi's manor was bought back by Li Zhen at a high price.
In order to increase the amount of grain assets, Li Zhen almost used the methods that he knew in his previous life and copied in Datang, and also hired dozens of old farmers who had a hand in farming as consultants.
So since then, Li Zhen no longer focuses on the improvement of crops, because he has understood that the reason why the crops in later generations can have such a high yield is not only high technology, but also the slow cultivation of the Chinese people for thousands of years.
Later, Li Zhen stopped paying attention to these things, but asked the people on the farm to keep the fullest, highest-yielding ears of wheat and other crops every year, and then keep them for next year's seeds, hoping to optimize the genes of the crops and slowly improve the grain yield - this was the inspiration he got from an article he read when he was a child called "Green Fingers", and the old grandmother used this method to grow white calendula.
Li Zhen doesn't know if this method is useful, but according to the theory of seed genetics, even if it can't completely optimize seeds, it should be able to increase some grain production.
In fact, what Li Zhen didn't know was that he found the right method by mistake, because in ancient times, the people of China did use this method to select seeds, and it is precisely because of hundreds of years of such breeding that there is a future Even if high-tech crop seeds have not yet appeared, the grain output in China can reach more than 200 catties (ask my father what he said, the output in six years is about so much, no chemical fertilizer, no farming machinery, only farm fertilizer and a cow), barely feeding hundreds of millions of people in China, In the end, it was the emergence of hybrid rice.
Now Li Zhen has used this method in advance, but this method takes too long, and it will not be effective at all without one or two decades.
So Li Zhen quickly put this matter aside and began to use a short-term effective method - that is, to open up a fertile land with high yields.
It was at that time that Li Zhen set his sights on Nanyang, and only by conquering this place could the Tang Dynasty temporarily solve the threat of hunger, and Li Zhen could buy more time to find new high-yield crops.
In other words, even if there is no offense from Lin Yi, Li Zhen will find an excuse to conquer Nanyang after stabilizing the situation in Lingnan.
Now Nanyang finally fell into the hands of the Tang Dynasty, but Li Zhen only found out at this time that it was not so simple to want to farm in Nanyang - there were too many natives in Nanyang.
The Tang Dynasty has just conquered Nanyang and has also carried out some immigration, but the number of these immigrants is very small, it can only be regarded as experimental, and the places occupied are also in the northern part of Linyi.
If you want to completely resettle and develop, you must carry out a major clean-up of the South Seas, and only after reducing the natives here to an acceptable level can the resettlement policy officially begin - although most of the slave catchers have entered here, it is not so simple to clean up the natives to a safe value range, and it will take at least three years or more.
After three years, the immigration work can be carried out completely, and it will take at least five years for the Tang people to fully adapt to the Nanyang environment and occupy Nanyang - that is to say, if you want to truly turn Nanyang into the granary of the Tang Dynasty, it will take about ten years less from Li Zhen to conquer here......
This is still a goal that can only be achieved with the full cooperation of the people of the Tang Dynasty, in case there is a mistake, such as the outbreak of chaos within the Tang Dynasty, this time will need to be longer.
It was with these in mind that Li Zhen took those high-yielding crops in the Americas to heart - he had even decided that if there was really no way, if the situation in Lingnan would develop in two years, he would be ready to take the risk of going to the Bering Strait himself, through which he would go to the Americas in search of sweet potatoes and corn.
But this is a last resort, because it is still dangerous to cross the Bering Strait in this day and age.
