The general trend of the Tang Dynasty swallowing the world has been achieved, Li Chengqian, Ma Zhou, and Tang Fengyi's plan is just to open the unification in the future, laying the groundwork, and the huge debts will make them try their best to expropriate and extort in the country, and riots will break out, and when the time comes, the Tang Dynasty will complete the liberation of the entire Eurasian continent with the attitude of maintaining world peace and liberating the poor people.

Li Shimin, who figured out this, was very pleased, so, no matter how well Li Tai planted the fields in Lingnan, his merits could not be compared with Li Chengqian, recently, the eldest grandson queen was most concerned about the marriage of their adult princes, Li Ke stubbornly wanted to marry Sun Xiaomei, for this reason, he did not hesitate to contradict the eldest grandson queen, for the sake of Concubine Yang's face, the eldest grandson queen did not care about anything with him, on the contrary, Li Shimin, who learned the news, issued an order to comfort Li Ke, and rewarded him heavily, This is also to show support for his pursuit of Sun's daughter.

As for Li Tai's side, Empress Changsun thought that she could decide with a word, after all, Li Tai was his biological son, but who knows, Li Tai did not agree to the person selected for him, but wanted to marry a girl of the Yi clan who was a female official in the art troupe, which made Empress Changsun angry, and almost caused all the qi diseases that she had not committed for a long time.

But who knows, after Li Shimin learned that the name of this Yi girl was Ah Yue, he raised his hands in approval, that girl Li Shimin had seen several times before, on behalf of Lingnan to Wangjianglou to give himself a song and dance, cut wheat in Guanzhong, and grew up under the edification and education of Sun Xiangfu and his wife, people are very kind, contented, and more and more beautiful.

The problem is that Li Tai's side is still a little uncertain, the prince of the Tang Empire, except for the crown prince, the prince with the highest title, marrying a relative, the woman of the other family will actually disagree, such a thing is impossible to happen for thousands of years, but in the Tang Dynasty, it exists.

Then, taking Ah Yue became Li Tai's political task, because his marriage made Li Shimin think of another problem.

The intermarriage between the royal family and ethnic minorities can make these ethnic minorities more loyal to the country, he himself is like this, the eldest grandson queen is a Xianbei tribe, since the Tang Dynasty, few people mention this ethnic group anymore, because, all belong to the Han people, even those Xianbei people have gradually disappeared, and they are basically gone in the Song Dynasty.

As a result, all the adult princes have a new task, and the guidance given by Li Shimin is to try to accept minority women as concubines, even if there is really no suitable one, at least one should be accepted as a side concubine.

Usually, if a minority with a small population has a princess-level figure, it will be difficult for it to have any rebellion, and when minority women become princesses and princesses, it becomes a trend, then it is difficult for them to separate themselves from this country, because half of the descendants of the royal family are of their own blood, except for those whose populations are so large that they can threaten the status of the Han population.

If the unification war of Eurasia is launched, the Tang Dynasty will really face such a problem, the Persians, the Great Cannibals, the Europa, and even the Tianzhu people are all larger than the current Han base, and these ethnic groups will become a threat to the existence of the Han population genes.

Therefore, Wen Yanbo, the right servant of Shangshu, who is committed to promoting ethnic integration and stabilizing the development of ethnic groups, put forward a proposal in the court to reform the marriage system.

Some restrictions on commoners taking concubines will be abolished, and the number of foreign women will not be limited, as long as the people can raise them themselves.

Moreover, once these foreign Hu girls marry the people of the Tang Dynasty, they can immediately get the household registration of the Tang Dynasty, and even, the imperial court will give encouraging policies, officials, public officials take Hu Nu as concubines, they can enjoy a certain number of days of marriage leave, and the civilians who have accepted foreign Hu Nu as concubines can be divided into different occupations, and the tax of one to two percent will be reduced or exempted for the next year, and the ethnic minorities in their own countries are not among them, because all of them who hold the household registration of the Tang Dynasty enjoy the same policy treatment as the Han people.

After the news was announced in the country, in the territory of the Anxi Metropolitan Protectorate, there was first a wind of women chasing men, and those countries in the Western Regions escaped the war and flowed into the territory of the Tang Dynasty. After this decree was issued in May of the ninth year of Jeongwan, the population may grow explosively.

In mid-July, Lingnan Road has selected a location for several fenced houses are almost built, Sun Xiangfu after inspecting the seedlings of rubber trees and sisal, then returned to Guangzhou City, ready to carry out the final harvest and data statistics of several field crops, rubber trees and sisal are different from potatoes and sweet potatoes Those crops with strong adaptability, their growth cycle is relatively slow, there are problems, and the cost of wasting time is larger, and Sun Xiangfu himself has not planted these crops in later generations, fortunately, there are several Mayan natives who have planted sisal, Combined with some of their experience, after two and a half years, there should be a lot to gain.

Moreover, Zhao He not only brought back the seeds this time, but also a lot of harvested sisal leaves and rubber sap released, which have been taken to Chang'an and handed over to various research institutes for research.

At the beginning of the month, Sun Xiaomei had a letter to come over, in the field, the first period, the last season of hybrid rice growth is good, the yield of the last season, reached eleven stone two, that is, 1344 catties, and this last season, if you can increase dozens of catties again, you should be able to achieve the expected yield, if you can plant more than 1400 catties, then the highest yield per mu of hybrid rice at present, even if it is on par with the nineties of the later generations.

In addition to the pest factor, there are two main reasons for the high yield of crops, one is the evolution of the seed itself, so that the imperfect gene becomes perfect, which is what hybrid rice seeds pursue, this point, at present, there are some advantages, that is, there are more original wild rice varieties produced in various places.

The second point is that fertilizer ensures that crops are nutritious in all aspects, just like people will gain weight if they eat too much high-calorie food, fertilizer is the high-calorie food of crops.

When the level of science and technology cannot reach the production of chemical fertilizers and help these crops to supplement nutrition in an all-round way, Sun Xiangfu uses the method of topdressing many times, within the range of the crop's tolerance, so that it has been full, two fat people, born cubs, are basically fat, so far, the effect is not bad.

Of course, he does not recommend that the people also use this way to increase the yield, because this requires the input of manpower, the cost of fertilizer is too great, only professional people, there is a breeding base, to help the people cultivate the best seeds.

Therefore, even if Sun Xiangfu's first phase of rice seeds reached the expected goal, and the rice seeds produced were handed over to the people to plant, they would plant a yield of about ten stones per mu at most, which had a lot to do with the fertility of fertilizer, insect control, and weed control technology.

The output of about 1,200 catties, although it is seven or eight hundred catties different from the general yield of 2,000 catties per mu in the Jianghan Plain in later generations, but in this period, it is enough, because there is no need to feed so many people now.

As for the people in the non-farmland area, they may be able to grow a yield of about seven or eight stones, but now that the crops in Datang are abundant, they may not need to plant rice, and it is very stupid to compete with others in terms of competing with others, and it is a good choice to choose emerging cash crops, corn, or various vegetable crops.

Judging from the growth of the corn field in Lingnan, its yield is still good, and it is much easier to grow than rice.

"Teacher, those Maya people who grow corn often say these days that our place is amazing, and the corn grown is much larger than their cobs, and the grains are fuller." After Li Tai greeted Sun Xiangfu at the gate of the city, he said happily.

"They didn't even know the basics of planting corn before, fertilizing, dressing, removing pests, cutting seedlings, and they could grow high-yield corn there, by the way, how did they know that the cob of corn was big, and whether it was eaten secretly?"

Sun Xiangfu glared at him, Li Tai suddenly touched his nose embarrassedly and said, "Well, those Mayans said that tender corn is the best when boiled, in order to please Ah Yue, I picked some boiled and eaten, it was very sweet, she liked it very much." ”

Sun Xiangfu knew that this was the case, and gave him a blank look and said, "It's useless for her to like to eat corn!" The point is whether she likes you or not. ”

Hearing this, Li Tai's face was a little broken, but after a while, he puffed up his chest again and said, "I will definitely make her like me." ”

Sun Xiangfu gave him an encouraging look and said, "I think you should be able to do it, as long as you keep working hard to make yourself better." ”

Love can change a person, and the advantage is that when you fall in love with a woman who has her own thoughts and is relatively independent, Li Ke is like this, and Li Tai is the same.

In fact, Li Tai was not the only one who stole the corn, Feng Ang also ate a lot when he was greedy, but after this thing entered the withering period, it was not so delicious when cooked, and Feng An's teeth were not suitable for gnawing old corn, so as soon as he received the news that Sun Xiangfu had returned to the city, Feng An, who had already packed up in the city and was about to leave for Jiangling, came over.

"Masaaki! Although the yield of this corn is high, the taste after aging is not as good as rice and wheat, and even worse than potatoes and sweet potatoes. After sitting down in the living room of the yamen of Li Tai's governor's mansion, Feng Ang said while sipping tea.

Sun Xiangfu smiled and said, "You can eat rice and wheat and get out of your shell!" This old corn! It is also to grind the flour, sieve the rough part, make pasta to be delicious, and its nutritional value is no worse than rice and wheat, and it has the benefits of lowering blood lipids, lowering blood pressure, anti-arteriosclerosis, anti-aging, etc., which is very suitable as a staple food. ”

Corn is recognized as a 'golden crop' in later generations, but if you really want to make it delicious, you still need to spend a certain amount of effort, at least, you need to grind it more finely, and then through multiple processes, sieve out impurities, if it can be fine like the powder ground by the machine of later generations, the taste of corn noodles and corn steamed bread can reach the extent that it is not lost to wheat, because it has a natural compound sugar sweetness addition.

When Feng Ang heard this, he suddenly realized, "It turns out that the old man's eating method is wrong, don't you say it, after eating this corn, when the old man came out, he was much more relaxed, and his whole stomach was lighter, it does have its benefits, as for how to grind noodles and make food, you have to teach everyone quickly." ”

Feng Ang has actually seen the benefits of corn, that is, when it is planted, it is less worry-free than rice, and the yield is not low, if its taste can be comparable to rice noodles, then Lingnan will definitely have to be planted on a large scale, so that a lot of manpower can be saved to do other things.

Of course, Sun Xiangfu knew his thoughts, and said with a smile, "With the climate of the Lingnan coast, corn can be planted at different times, so that you can have tender corn to eat all year round, but when it comes to grinding cornmeal, I think that sweet potatoes and potatoes can also be made into vermicelli, so that it is more convenient to store as a staple food, and before we go to Jiangling, we can get some out." ”

"Sweet potatoes can also be made into vermicelli? This old man wants to see and understand, what tools do you need, you say quickly, the old man will find someone to arrange. ”

It is said that the yield of corn is large, but compared with sweet potatoes and potatoes, it is far worse, but Feng An, who has eaten sweet potatoes and potatoes, feels that these two crops seem to be more suitable for cooking, and if they can be made into things like rice noodles, it would be great, this is a crop that can be more worry-free than corn.
