In the summer grassland, there are many mosquitoes.

The grasslands around the Yellow River are the most fertile grasslands.

Since Li Jing led the army to destroy the Eastern Turks in the fourth year of Zhenguan, Xue Yantuo, under the leadership of Zhenzhu Khan Yinan, took over most of the territory of the Eastern Turks.

The original people and horses of the Eastern Turks basically moved south to the south of the Yellow River as a barrier to the Tang Frontier.

This strategy, if it is placed in later generations, will definitely be very criticized.

However, judging from the situation at the time, it cannot be regarded as a failure.

On the whole, in the Zhenguan Dynasty, the Eastern Turkic nobles after surrender were still more obedient and loyal to the Tang Dynasty, basically playing the role of a barrier on the frontier.

"Khan, in front of you is the location of a large tribe of more than 3,000 people in the Eastern Turks, let the children lead the troops to give them a little color."

As the eldest son of Zhenzhu Khan, Lu Mang also personally followed Yi Nan on the expedition this time.

It turned out that since the Tang Dynasty adopted the method of "pushing the grace order" last year, Yi Nan's control over Xue Yantuo has greatly decreased.

In order to avoid further deterioration of the situation, he decisively provoked the contradiction between Xue Yantuo and the Eastern Turks.

First, there were some skirmishes between the two sides, and now, Yi Nan simply led the army to attack the Eastern Turks.

"A tribe of 3,000 people, you don't have to work big brother, you can do it, just take care of it."

Yi Nan's eldest is not far behind.

For Xue Yantuo, most of the things in the territory that were attacked by any tribe belonged to this tribe.

In other words, if Trolley defeated this tribe of more than 3,000 people, then the final result was likely to be that he got a group of cattle, sheep and captives, and his strength rose to a new small level.

Bazhuo is naturally very aware of this situation, so he will fight for every battle.

Battles on the grasslands often take place in autumn, when cattle, sheep and horses have grown fat, and the herdsmen have begun to be idle.

However, this time, Yi Nan couldn't help but send troops in the summer.

If you really don't make any more moves, this autumn, Xue Yantuo himself may be about to fight.

However, in this way, the war will not last long, after all, the Eastern Turks are covered by the Tang Dynasty, and Yi Nan does not dare to completely turn his face with the Tang Dynasty.

"You don't have to fight, one from the left, the other from the right, let's go together."

Yi Nan naturally knew the careful thoughts in the hearts of his two sons, so he simply adopted a compromise method.

With Yi Nan's order, Lu Mang and Bazhuo each led an army of 10,000 and headed towards the tribes of the Eastern Turks.

……

Next to Weishui, there are hundreds of acres of paddy fields that are particularly eye-catching.

There are still two months before the Mid-Autumn Festival, and the golden ears of rice are constantly swaying in the breeze.

It is golden, like someone who has laid a layer of gold in the field.

"Lord Wang, this rice from Nanyang is really unusual, it has matured so early."

Wang Xuance followed behind Li Kuan and personally confirmed the situation before the rice harvest.

Because of the climate, Li Kuan did not let people plant double-cropping rice in the paddy fields in large quantities, but only arranged a few hundred acres for trial planting.

The seedlings of these trial rice fields are all raised in the greenhouse, which can be regarded as saving a period of time.

Otherwise, the surrounding area of Chang'an City is really not the best place to grow double-cropping rice.

Now that the early rice in Chang'an City has been ripe, it must be arranged to be planted in Hangzhou and Mingzhou.

"Well, it's ripe, but this ear of rice is still not long enough."

Li Kuan saw rice for the first time in Datang, but as a baby who grew up in the countryside, he still knows a lot about the situation of rice.

For example, the relatively high-quality rice in later generations, the length of the rice ear alone can reach 15 centimeters, or even longer, and the grain is full, and the yield per mu can easily reach 1,000 catties.

But these rices in front of him, although Wang Xuance felt very surprised, Li Kuan felt that it was still not good.

This yield is definitely less than half of that of later generations, and if you die, you will yield two or three hundred catties of rice per mu.

"Lord Wang, this is already very good, I heard from a Jiangnan businessman who has planted rice that our rice grows better than anywhere he has seen."

There is no harm if there is no comparison, Wang Xuance obviously doesn't understand why Li Kuan is still dissatisfied.

"Forget it, it has solved the problem of two seasons of planting, and there is a yield of four or five hundred catties a year, which is still much stronger than corn."

The rice of the Tang Dynasty, even if it is a rice seed of the South Seas, is still incomparable with the hybrid rice of later generations.

Thinking about it this way, Academician Yuan is really a great hero!

"Then the subordinates will arrange for people to harvest tomorrow, do you need to invite Dai Shangshu from the household department to come over and have a look?"

Wang Xuance was well aware of Li Kuan's purpose and determination to promote rice cultivation.

This early rice is ripe, and although the seedlings of late rice have not yet begun to be planted, it is almost foreseeable that double cropping rice does exist and can be promoted in Datang.

"Well, also send a post to Fang Xiang and Wen Xiang to see if they are interested."

In order to popularize rice in Datang as quickly as possible, Li Kuan is not prepared to adopt the method of popularizing woad vegetables.

Food is too important, and the grain production in this era is too low.

The ability of ordinary farmers to resist risks is very low, and when there is a famine, the victims are killed.

……

A lot of rice is grown in the Chu Palace, which is not news, and anyone in Chang'an City has heard of it.

However, it is still June, and since Li Kuan invited himself to watch the rice harvest, this makes Dai Zhou and Fang Xuanling feel strange.

However, considering that there were many strange things in the Chu Palace, they all came to the Chu Palace's courtyard after the next day.

Then, under the personal leadership of Li Kuan, he came to the side of Waseda.

"This Nanyang rice seed is really a little different, it is ripe in such a short time."

Seeing the golden rice field in front of him, Fang Xuanling was a little surprised.

It's really cooked!

You must know that it has only been more than three months since the rice was planted, and it basically takes five or six months to harvest corn if you plant it normally.

Although it is not sure whether it can really be successfully planted for another season, Fang Xuanling is already a little surprised.

Li Kuan said disapprerovitically: "Early rice and early rice, if it can't mature early, it will delay the planting of late rice." ”

"His Royal Highness the King of Chu, I heard that you still have a lot of fish in this rice field?"

Wen Yanbo on the side remembered the rumors at the beginning of the year, and he didn't know what the situation was now, whether it would be that grass carp and crucian carp would be produced together after the rice was harvested.

"Wen Xiang, because this early rice field has to be planted for two seasons, the rice planting is relatively early, and the fish fry are not ready at that time, but there is no fish raising. However, there are a lot of fish in the middle rice field next to it, and it is estimated that there is already about a pound of grass carp. ”

Cotton and rice are the two crops that Li Kuan is most concerned about this year.

No matter which one it is, it is of great significance to Datang.

So no matter what Fang Xuanling asks, as long as it is related to them, Li Kuan can basically answer.

"This rice looks good, and now that it's ripe, let's start harvesting."

Dai Xuan picked a bunch of rice ears and took a good look at them.

Although the paddy looks good, no one knows what the yield will be until it is actually harvested.

So whether it's Dai Xuan or Fang Xuanling, everyone's performance is relatively normal.

Li Kuan didn't say much about it, in fact, he was also a little curious about the yield of this rice.

This piece of land is very regular, and someone has already measured the area, and when Li Kuan gave an order, more than a dozen farmers went down to the field to work together.

I saw the sickle waving from field to field, and soon bundles of rice plants were placed among the ridges of the field, and a farmer began threshing on the single scale.

Wang Xuance had already arranged everything in advance, but it was only a quarter of an hour's work, and half an acre of land had already been harvested.

"Lord Wang, it's more than one hundred and fifty pounds."

didn't wait for all the acres of land to be harvested, Wang Xuance couldn't bear to let people start weighing first.

"Hmm."

"Huh?"

Li Kuan and Dai Guan's reflections were completely different.

"What do you say, it's already more than one hundred and fifty pounds?"

Just now, Dai Xuan didn't pay much attention to the threshing situation in the single scale, but now he suddenly heard that it was more than 150 catties, and he felt that he had heard it wrong.

Although it is rice that has not been dried, it is still very scary if it is more than 150 catties, even if it is dried, it is 120 catties, which is basically equivalent to the harvest of one mu of corn.

"Dai Shangshu, from the harvesting of rice to threshing, it is all carried out under everyone's noses. If you don't believe what we say, you should believe your eyes, right? ”

"His Royal Highness the King of Chu, this rice is not a rare crop, there are many people in Jiangnan Province who grow it, why have I never heard of such a high yield?"

Wen Yanbo personally went to confirm the rice that had just been weighed, and it was really more than 100 catties, which made him feel very surprised.

"The seeds are different, if the rice seeds of Jiangnan Province are planted here, it is estimated that one mu of land can only produce about 100 catties, which is not as good as Jiangnan."

Rice is not so mysterious, and what people don't understand is why there is such a big difference in yield.

"I heard that in the Agricultural College of Guanshishan Academy, all students study how to improve seeds in the greenhouse and in the ground every day, could it be that if the seeds have changed, the yield will be so great?"

Fang Xuanling was very excited in his heart, but his kung fu of controlling his expression was very good.

"That's right, in fact, everyone saw this situation a few years ago. After several years of improvement, the yield per mu has increased several times, and the shape has also changed greatly. If the seeds of this rice can continue to improve, let alone the yield of two or three hundred catties per mu, it is normal to double it again. ”

In the absence of pesticides and chemical fertilizers, rice with a yield of 1,000 catties per mu is basically not even thought about.

Li Kuan only hoped that he could increase the yield of rice per mu in Datang to 500 catties, and he was very satisfied.

However, Fang Xuanling and the others selectively ignored the second half of what Li Kuan said, feeling that it was just a metaphor.

"If these rice varieties from the South Seas have such a high yield per mu, then this significance is too great."

Fang Xuanling began to look forward to the arrival of autumn, and the tens of thousands of acres of rice in the Chu Wangfu were harvested together, which could completely prove how the yield of rice was.

Moreover, with these tens of thousands of acres of rice seeds, even if it is to be promoted on a large scale in Datang, it can be regarded as having the basic conditions.

In the midst of everyone's discussion, the first mu of early rice has been harvested.

"Three hundred and twenty-four catties, Lord Wang, the acre of land we chose is the most ordinary piece of land, and basically the others will not be worse than this."

Wang Xuance's face was full of smiles.

was watched by the Xungui of Chang'an City for a few months, and now he has finally pulled back a game.

"If the yield is still so much, I don't think we need to wait for the autumn harvest anymore, and now we can think about how to promote rice planting next year."

On the way here, I also passed by a large area of one-season rice planting, and those rice seedlings grew very strong, and it didn't look like the yield would be worse than this.

"Yes, if rice is planted in Guanzhong Province, then next year's grain production will be doubled, and farmers will no longer have to worry about hunger."

Dai Xuan excitedly kept stroking his white beard.

"Ahem!"

Li Kuan had to interrupt Dai Guan's fantasy, "Dai Shangshu, there are not many areas suitable for growing rice in this middle road. The main thing is that people are not used to eating rice, and if you want to promote rice, I think Gangnam-do and Sannam-do are the best places. ”

Su Changshu, the world is full.

During the Song Dynasty, there was this statement, which is enough to show that the grain development potential of Suzhou and Changzhou is huge.

Jiangnan has a dense water network and the temperature is warmer than Guanzhong, and the most important thing is that the area can be easily connected to the Grand Canal, transporting locally produced grain to all parts of the country.

As for Shannan Road, Li Kuan thought of the Jianghan Plain, which is also a big granary.

It's a pity that when I was in Datang, the development was still very slow.

You must know that Xiangyang in later generations is also an important grain producing place in the country.

Of course, Li Kuan's choice of Shannan Road is also a very important factor is that it is very close to Chang'an City, almost a suitable place for planting rice, and Shannan Road is the closest to Chang'an.

After the rice cultivation here in Shannan Province developed, it continued south to Ezhou in Jiangnan Province (I have to complain, the Jiangnan Province of the Tang Dynasty is too big, and all or part of Jiangsu, Zhejiang, Fujian, Hunan, Hubei, and Anhui provinces belong to Jiangnan Province, no wonder Tang Xuanzong later split it into Jiangnan West Road and Jiangnan East Road).

Ezhou is now Wuchang, and it is also a good place for the development of agriculture.

"What His Royal Highness the King of Chu said is that the yield of this rice from the South Seas is higher than that of corn, and it is also higher than the original rice yield of Jiangnan Province. If it is really promoted, it is easiest to promote it in Gangnam Province. ”

Fang Xuanling immediately accepted Li Kuan's suggestion.

It seems that rice production can be increased wherever it is promoted, but if you choose the wrong place, it will be much more difficult to promote.

For example, in Hebei Province, if you force the farmers there to change to rice, they will not have to rebel?
