?

After hearing Yuwen Wen's malicious question, Yang Ji's heart skipped a beat and said that it was not good, and he couldn't leave. Besides, he could hide for a while and could not hide for a lifetime. In desperation, he could only bite the bullet and explain a little.

Seeing that Yang Ji was so aware, Yuwen Wen directly told him a major "discovery" today: after the autumn harvest, both the official fields and the farmland were idle. He had been busy training and fighting before, and it was not until now that he had visited the official fields to discover this situation.

"Eunuch, it's normal for rice to ripen every year at this time." Yang Ji replied. The person on the opposite side seemed to know everything, but the agriculture was almost Bai Ding, which made him quite 'proud'. "If you want to ripen twice a year, you will get the Song Dynasty."

"I know, but I think it's too wasteful and can't find rice seeds that are ripe a year."

"What does the envoy mean?"

"We need to find a way to increase the yield." Yu Wen Wen looked solemn.

Rice can be divided into early, middle and late. Early rice is usually harvested between June and July, while the rest are between August and September. However, in any case, most of the rice grown in Jiangnan in this era is a season of rice, which means that it is ripe every year.

This problem arises. After the autumn harvest, the farmland will be idle. Of course, it is also a good time to recruit farmers to fight. However, Yuwen Wen doesn't think so. He thinks that it is enough to use professional full-time soldiers to fight ordinary wars. It is better for farmers to have multiple lands, and idle farmland is a waste.

Seeing the empty farmland, he was depressed: Are you making a mistake? There is too little land. You have left me idle for a few months. In order to find a way to stock up on food and raise soldiers, I have lost my hair and lost my soul!

Yuwen Wen wants to make use of all the resources that can be used. Naturally, the valuable resources of farmland cannot be wasted. There are rice seeds that can be ripened twice or even ripened three times a year. The famous Chameng rice is one of them, but he cannot get it for the time being.

The large-scale promotion of Chameng rice in the Central Plains was in the Song Dynasty. Of course, it does not mean that Chameng would not have this kind of rice until the Song Dynasty. Therefore, it is possible to get it in this era, but the key is a matter of time.

Chameng is far south of Southeast Asia, that is, to Jiaozhi, and can be found in the Rinan County of Chen State. Although it is okay to let merchants who have no profit and cannot get up early, who would have obtained it would be the year of the monkey, not to mention being cheated by someone using counterfeit goods, everything is possible.

There should be local rice seeds ripening in Lingnan area two years, but Yuwen Wen is not an agricultural expert. Instead of traveling all over the mountains and rivers to find this kind of rice, it is better to make rice in the city directly.

If rice seeds cannot be solved in a short period of time, it will become inevitable to make a fuss on the land. There is a saying that goes, "If you can't change your girlfriend, then change your posture."

In today's era, there is a saying about crops called "southern rice and northern millet". Of course, wheat cultivation has also begun to become popular. The wheat planting area in the north is expanding, and a few places in the south have begun to start planting. Yuwen Wen's idea is to make wheat.

"Do you want to rotate rice and wheat?" Yang Ji asked. The man in front of him was indeed a reluctant person who was unwilling to do anything to increase his yield.

Rice and wheat rotation was generally believed to have emerged in the Tang Dynasty and became popular in the Song Dynasty. Especially after the Southern Song Dynasty developed the Jiangnan River Basin, rice and wheat rotation became a common phenomenon. As the name suggests, rice and wheat rotation was to rotate rice and wheat on the same piece of land.

It sounds very simple, but it is a bit troublesome to make. The south has water seeds, so most of the rice is planted. Rice naturally grows in paddy fields, while wheat is a dryland crop. If you want to rotate rice and wheat, you have to solve this problem.

After the autumn harvest of rice, drain the paddy fields into dry fields, and then quickly plant winter wheat. After harvesting the wheat in the spring of the next year, quickly store water and turn it into paddy fields. Then immediately plant rice until the autumn harvest is harvested and recycled again.

In this way, the harvest of the same piece of land increased significantly. Yuwen Wensi thought about it and felt that only in this way could the problem of idle farmland be solved. Then Yang Ji poured a basin of cold water directly: it would be impossible if it was implemented in a hurry.

Seeing Yuwen Wen ask about the reasons, Yang Ji talked about it one by one:

When rice and wheat crop rotation, it is important to whether the harvest and sowing of the two crops can be smoothly connected, especially after autumn harvest, the time interval of wheat is very short, which will increase the amount of labor. In addition, the drainage of paddy fields turns into dry fields, which will test the drainage capacity of drainage ditches.

When drainage in paddy fields, it will take for them to be suitable for wheat planting? No one knows this, so we have to explore. What if the wheat does not grow well if it takes a short time, and what if it delays sowing if it takes a long time.

In spring, wheat has to be harvested and then planted rice, and it has to be troubled. The dry fields have to be released into paddy fields. If improper operation will affect the rice harvest of that year, it will be more than worth the loss.

Of course, farmers are very welcome to increase their yields, and it doesn’t matter if they are tired. However, as a result, most of the year is busy farming, and the state government will recruit strong military service, so military service will inevitably be subject to period restrictions.

Another point is that according to the laws of various countries today, the annual rent and adjustment are only collected once after the autumn harvest. The income from planting winter wheat is not required to be paid. If you want to increase the income of the state government, the consequence of forcibly increasing the rent will be to incite civil unrest.

"The most urgent task is to popularize the transplanting method. If the people are not familiar with the transplanting method, they will take another rice and wheat rotation. If the connection between them is not connected, they may have a bad harvest."

"What if it is a trial in the official field?" Yuwen Wen asked, but then he rejected his idea. Now that the autumn harvest has passed, if you want to plant wheat, you have to drain the paddy fields, and secondly, you have not prepared enough wheat seeds, it is impossible to implement this year.

"Your Majesty, if you can't chew too much, you should make it the first step to popularize the rice transplanting method." Yang Ji advised that the rice transplanting method should be popularized in the Bazhou area in the beginning of next spring, and officials from other states came to learn it. As the saying goes, one mind cannot be used for both purposes. He thought it would be better to try rice and wheat rotation next autumn.

"Well, leave a year to plan well and strive to be piloted after next autumn." Yu Wen Wen nodded. Grain production is of great importance. The most urgent task is to repair the water conservancy first, so that the north bank of Santai River is protected from floods and increase the land area that can be reclaimed.

The grain output of newly reclaimed farmland is definitely not high, and it will take a few years to reach the ordinary level. During this period, it will also require careful cultivation, and the output cannot be doubled when you wake up.

"What the envoy said before, go to the new continent... the Western Yi said to look for corn, sweet potatoes, and potatoes. Is this true?" Yang Ji asked again. He came from the late Ming Dynasty and knew that the Western Yi found the new continent very far east of the East China Sea, with many magical crops like corn on it.

Corn, sweet potatoes, and potatoes were promoted in the late Ming Dynasty, but natural disasters and man-made disasters failed to play a role as soon as possible. Years of severe droughts made the crops completely harvested, and the increasingly heavy Liao gulf forced countless hungry northern people to resist.

Yang Ji always felt that if the imperial court could promote these crop plantings as soon as possible, he would probably have survived the Chongzhen period. If it weren't for internal and external difficulties, His Majesty would not have died in Coal Mountain.

'Here comes again, I'm in the Ming Dynasty again...' Yuwen Wen was speechless. The court in front of him was not the current court, and His Majesty was not the current emperor. However, what he said before was to find peppers, corn, sweet potatoes, and potatoes, which was not entirely a joke.

The promotion and cultivation of corn, sweet potatoes and potatoes was the reason for the significant increase in population in the late Ming and early Qing dynasties. The advantages of these crops are high yields and low requirements for arable land, which can greatly increase land utilization.

However, these crops have low calories, only half or even one-third of the rice with the same weight. In other words, to maintain the basic caloric needs of the human body, the consumption of corn, sweet potatoes and potatoes is significantly more than rice. Of course, this is usually the case, and the special variety is a different matter.

Therefore, the biggest function of corn, sweet potatoes and potatoes, which are known as the magical artifact, is to save wasteland. They do not need complete land. Even scattered and broken land can be planted on slopes. The unit calories are not high but the amount is large, which can fill the hungry people's stomachs.

There is a disadvantage of corn, that is, it requires a lot of water when growing, which can easily lead to land water loss. During the Qing Dynasty, corn planting was promoted, and many mountains and forests were cut down and turned into sloping farmland. The large amount of corn planted actually led to aggravation of soil erosion.

Therefore, to farm and increase income, it depends on rice. In this era, the development level of the two lakes is not high. As long as water conservancy can be built, schistosomiasis can be controlled, and wasteland will be turned into fertile fields, the rice produced will be enough to feed the people of this era.

"Huguang is familiar with it, and the world is full." This is the incident after the Song Dynasty. Today, Huguang area is still in the initial development stage.

Yuwen Wen was not interested in corn, sweet potatoes and potatoes far away in the Americas. The kingly way was to build water conservancy and cultivate rice. What he was most worried about was chili peppers. Chili peppers were native to Central America and were not introduced to the Central Plains until the middle and late Ming Dynasty, but this thing was really a good thing.
