Of course, Liu Xin understands that the strategic significance of hybrid rice is more important, after all, the annual output of hybrid rice is about seven or eight times that of any grain crop in Dahan, which means that if hybrid rice is planted in the whole territory of Yizhou, then the annual output of hybrid rice in Yizhou alone is equivalent to the total output of grain crops in other states in Dahan. Pen, fun, and www.biquge.info

What kind of concept is this, this represents the opportunity for Yizhou to be able to control the price of grain in Dahan, and the strategic significance is self-evident.

However, it is still that problem, the task given to Liu Xin by Tiandao stipulates that the five crops must be promoted to all parts of the Han Dynasty, so Liu Xin can only hold the idea of seeking well-being for the common people in the world, and promote hybrid rice to all parts of the Han world!

After choosing the second crop seed, Su Jia also put forward her own suggestion at this time: "Master, I personally think we still need one more crop seed - that is, potatoes. ”

Liu Xin nodded thoughtfully, potatoes are a good thing, not only can they be used as staple foods alone, but also as vegetables, and whether they are fried and fried alone, or cooked with other ingredients, the taste is excellent.

Liu Xin has always liked to eat potatoes since he was a child, and he has never been bored, but now that he has traveled to the Han world, Liu Xin has never eaten fresh potatoes, and can only use potato chips to satisfy his hunger.

The reason for this is very simple, there were no potatoes in the Han Dynasty, because potatoes are native to the Andes Mountains of South America, and the history of artificial cultivation can be traced back to the southern region of Peru from 8000 to 5000 BC, so potatoes are still facing the Han across the sea.

Liu Xin felt deep despair when he thought of this, which meant that he would not be able to eat potatoes again in ten years.

Although there must be potato seeds in the warehouse in Chengdu, according to Liu Xin and Su Jia's analysis of Tiandao, it is very likely that Tiandao will not return the crop seeds to Liu Xin before the unification of the Han Dynasty.

Therefore, if Liu Xin wanted to obtain potato seeds before the unification of the Han Dynasty, he could only build a port after taking Jiaozhou, and then build ocean-going ships to go to the Americas to obtain seeds for various crops.

However, these two methods of obtaining potato seeds will take at least ten years, after all, the Han is so big, there are so many princes, even if Liu Xin has a lot of advantages, but it is not a simple matter to turn the advantage into victory - just like Cao Cao after the unification of the northern Han Dynasty, before the Battle of Chibi had such a big advantage, looking at the cards can completely crush the alliance established by Sun Quan and Liu Bei, and there is a great tendency to sweep the world, and the end of the troubled times is just around the corner.

If it is replaced by a popular phrase in the interstellar 2 circle, Cao Cao is how to lose the flying dragon riding face?!

As a result, Cao Cao was milked to death by a mouthful of poisoned milk, and he was defeated in the Battle of Chibi, and finally formed a situation of three kingdoms.

So an advantage is not the same as a victory.

Therefore, Liu Xin conservatively estimated that it would take at least ten years for him to defeat all his opponents and unify the Han Dynasty.

The reason why it takes such a long time is mainly because the goal is to unify the Han Dynasty, and now the Han has a lot of legal territories controlled by foreign races, for example, half of the territory of the Bingzhou side is still in the hands of the foreign race, although most of the Han territory on the Xiliang side is in the hands of the Han Dynasty, and it is not as serious as the Merge State, but there is a very serious problem in the Xiliang region, most of the military governors of the Xiliang have inexplicable connections with the Qiang people, and the control of the Xiliang troops by the Han court is not optimistic.

Then there is the Nanban tribe in the Yizhou and Jiaozhou regions, the Di tribe at the junction of Yizhou and Liangzhou, and the Shanyue tribe in the Dongwu region, these alien races also control a large number of Han territories, so if Liu Xin wants to unify the Han Dynasty, he must also solve them one by one.

That's why Liu Xin will make a prediction of unifying the Han in ten years, and this is still the most idealistic result, Liu Xin feels that even if he can unify the Han in fifteen years, it can be regarded as thankful.

Getting back to the point, Liu Xin realized that he had forgotten that there was an option like potatoes in crop seeds.

By the way, a little knowledge of popular science, in 2015, China has launched potatoes (at the official level, potatoes are called potatoes, but potatoes are more suitable for national conditions, so this book is called potatoes) staple food strategy, advocating that potatoes will be processed into steamed buns, noodles, rice noodles and other staple foods, so potatoes will become rice, wheat, corn in addition to another staple food in China, because China is now the world's largest potato producer.

Having said that, if potatoes are used as a staple food, Liu Xin feels that potatoes have more advantages than hybrid rice, after all, potatoes are not inferior to hybrid rice in terms of nutritional value.

Because of the growth habit of potatoes, they suffer much less pests and diseases than hybrid rice, and only need sufficient water to grow smoothly, and the breeding speed is extremely fast, which can be promoted to the whole Han in a short time, because potatoes only need to be cut and sown, which is much simpler than planting hybrid rice.

Moreover, the yield of potatoes per mu has reached an astonishing 4,000 catties, and according to the planting conditions, it can be planted three or four times a year, that is, the annual yield of potatoes is tens of thousands of catties!

When potatoes were introduced to China around the 16th century, the famine problem in China was alleviated to a certain extent, because potato tubers are rich in dietary fiber and rich in potassium salts, which are alkaline foods. According to some sources, its content is as much as apples, so the absorption of potatoes by the stomach and intestines is slower, and after eating potatoes, they stay in the intestines for a longer time than rice, so they are more satiety, which is more hungry for the victims of the famine, so potatoes are an excellent food for disaster relief.

Speaking of the medicinal properties of potatoes, yes. It is the medicinal value of potatoes, which sounds very mysterious, after all, potatoes are a very common food, and no matter how you look at it, it has nothing to do with medicinal herbs.

But as an old Chinese medicine doctor, Liu Xin must correct the name of potatoes, which have extremely good medicinal effects in both traditional Chinese medicine and Western medicine.

According to traditional Chinese medicine, it is sweet and non-toxic, can strengthen the spleen and stomach, invigorate qi and regulate the body, relieve pain and relieve pain, and facilitate bowel movements. It has a significant effect on patients with weak spleen and stomach, indigestion, gastrointestinal disharmony, abdominal pain, and poor stool, and is mainly used to treat stomach pain, ribs, carbuncles, eczema, and burns.

I won't say that the above paragraph was written by Liu Xin directly... Back then, Liu Xin was desperate to die of these backs, and there were hundreds of medicinal materials to carry, and now I think about it, I feel that Liu Xin's lazy cancer is all because he was forced out after memorizing these...

In Western medicine, it is also affirmed that potatoes can regulate the spleen and stomach, and can also help digestion, detoxify and nourish the skin, and may even prevent stroke.

All in all, potatoes are a good thing, so Liu Xin is very optimistic about the development of potatoes in Dahan, and they can definitely become the first staple food in Dahan.

Thinking of this, Liu Xin took out his mobile phone to check the rating list about potatoes.

I don't know if I don't search, I was shocked by a search, there are more than 200 kinds of potatoes in the warehouse in Chengdu, and there are many colorful potatoes with excellent ornamentation, and the top three in the rating list given by Tiandao are all covered by colored potatoes.

Liu Xin clicked on the black potato that ranked first and found that the black potato was actually a special potato cultivated by a domestic research institute.

And according to the evaluation given by Tiandao, the reason why black potatoes appear black and purple is because black potatoes contain a large amount of anthocyanins, and these anthocyanins have anti-aging effects and are very beneficial to the human body.

At the same time, black potatoes also have the characteristics of developed main stalks, few branches, strong growth potential, and strong disease resistance, and the yield per mu can reach 1,500 kilograms, which is about 20 percent higher than that of ordinary potato varieties.

So this black potato is not the kind of potato that is not used in the middle, it not only looks good, but also the quality is excellent.

Black potatoes can obviously rely on their appearance to be an idol in potatoes, but black potatoes are a real powerhouse.
