Why doesn't Chongzhen promote red rice, that is, sweet potatoes?

The first is that sweet potatoes are not tasty.

Delicious roasted sweet potatoes and dried sweet potatoes are essentially snacks, not staple foods.

If you eat sweet potatoes as rice, then it is not as good as other staple foods in terms of nutrition and taste.

Long-term consumption of sweet potatoes is easy to reflux acid and unappetizing eating.

Sweet potatoes are low in protein and lack some of the vitamins contained in brown rice and wheat, making them malnourished when consumed for a long time

The second is that farmers are not highly motivated to grow sweet potatoes.

Farmers in the real world are not as "simple" as the old farmers in the online article, as long as they have a stutter, even if it is pig food, they will smile and never rebel.

The peasants not only had to eat food, but also to dress themselves, buy salt, see a doctor, and save money for their wives, coffins, and sons' wives.

This is achieved by selling grain, and if you can sell it at a high price, you have to sell rice, wheat or millet.

Sweet potatoes are not only not delicious, but also resistant to storage and easy to mold, so how can farmers sell them when they grow them?

If the old farmer is allowed to eat sweet potatoes with sweet potato leaf soup, they might as well start this kind of life.

Finally, in the long run, Chongzhen has no intention of promoting such high-yielding crops at all, at least not now.

Solving the problem of ecological collapse in the mixed agricultural and pastoral belt of the Loess Plateau through tuntian fields and high-yield crops is like fighting a fire.

The salary is inexhaustible, and the fire is not extinguished.

From the Qin and Han dynasties, in order to defend the frontier, he built a large tuntian on the grassland of the border county.

As a result, the situation was very good at the beginning, after all, for the Chinese with the traditional concept of more children and more blessings, there is more food, more people can be fed, and the population is naturally raised.

However, as the population exceeded the ecological carrying capacity, the Han Dynasty's control of the northwest frontier continued to decline, and by the end of the Eastern Han Dynasty, the Qiang Rebellion in the northwest became a major problem.

Although Liangzhou Sanming had a certain effect on the use of troops in Xiqiang, the Han land was still shrinking, and when the Western Jin Dynasty was born, the bald tree function rose, which made the Jin Dynasty even more frightened.

The same was true in the Ming Dynasty, which originally did not have such multilateral towns on the northwest border, and mainly relied on the two kings of Qin and Jin to guard the border.

As a result, the vassal system collapsed after the Jingnan, and the Ming emperor successively set up four border towns in the northwest and greatly developed Tuntian.

In the middle of the Ming Dynasty, Shaanxi was once known as Fengsuo, not to mention the Guanzhong Plain, and the tax task of a year can be completed in ten days.

As for the border towns, relying on tuntian, they can also be self-sufficient, and even can be transported to the surrounding areas.

But by the end of the Ming Dynasty, the evil consequences in the grassland began to appear, and the soil erosion was serious, and the mountains in the northwest could not even see the roots and trees.

This man-made ecological disaster, superimposed on the drought of the Xiaoice River period, was the natural cause of the fall of the Ming Dynasty, which actually repeated the mistakes of the Western Jin Dynasty.

Looking at the whole country, in fact, it is the same. At the peak of the feudal dynasty advocated by many online articles, what about the Manchu Qing Dynasty, which had the three major killing weapons of "spreading the land into the mu, never increasing the endowment, and high-yield crops"?

The Chinese population has increased sharply from 60 million to 400 million, the destruction of ecological vegetation has accelerated, the involution gene has begun to be implanted, and the average height and physique of Chinese people have begun to deteriorate sharply, and it has not begun to recover until recent decades.

The lives of these people, and the ecology of the time, can be seen in black and white photos on the Internet today.

If this is the pinnacle of the feudal dynasty, Chongzhen feels that it is really not necessary.

In fact, Chongzhen found in the simulation that Daming has never lacked food, what Daming lacks is the ability to transport grain to the place of famine.

Or, what is most lacking is the ability to export purchasing power to the affected population.

After all, the Ming Dynasty, which has been monetized after Zhang Juzheng's reform, is the most efficient is silver, but Chongzhen is the most lacking in silver to distribute to the victims.

Later, Chongzhen was inspired by the original Ming Dynasty's policy of "opening salt to China" in a simulated war, that is, salt was introduced to border towns, and grain merchants were used to exchange grain for salt in local areas.

Although this policy had failed, Chongzhen at that time replaced it with "tobacco leaves in the middle", allowing grain merchants to exchange grain and other daily necessities for tobacco after arriving in the border towns.

Because tobacco is not only drought tolerant, but also can grow in barren land, and at the same time is a stearful commodity throughout the Ming Dynasty and even in Mongolia.

Later, northern Shaanxi formed an economic cycle with Saiwai and the inland, and the income of the local people increased greatly.

It's a pity that because Lin Dan Khan was red at that time, he repeatedly entered the border, and smashed the border at that time, and threatened the northwest for a long time.

Faced with a two-front battle again, Da Ming in that simulation still did not fall.

Therefore, this time, Chongzhen did not intend to let the local farmers and merchants sell it on their own, but to purchase it by the supply and marketing cooperatives, so as to make a fortune and avoid being targeted by Lin Danhan again.

After laying out the northwest, Chongzhen focused his attention on the construction of Yingchang City.

At present, Chongzhen transferred 5,000 cavalry led by Fried Rabbit from the Mangui Army, and temporarily transferred Chen Qiyu to Jin Fu to exterminate the peasant army.

Man Gui led 20,000 foot soldiers to start repairing Yingchang City, which was also his old job.

Back then, Ningyuan City was recommended by Yuan Chonghuan to be repaired and rebuilt.

Now Mangui has commanded his subordinates and the Karashen people who surrendered, and initially rebuilt the rammed earth city wall outside Yingchang City, which is also a cattle and horse wall.

In this way, in the event of an attack by the enemy while the Karashen tribe was grazing, the city would not dare to let these herdsmen and cattle in, but they could be placed between the cattle and horse walls and the city walls.

The Ox Horse Wall itself also had firing holes and gun emplacements, and it was not much of a problem to deal with small groups of enemies.

At present, Mangui is rebuilding the walls of Yingchang City.

When the old Khan of Karashen built the city, he did not consider that the walls should be protected against artillery.

Therefore, several straight city walls were built directly with green bricks, and the middle was extremely thin.

This kind of vertical wall is enough to deal with bow and arrow slashes, but once the cannon is pulled, a cannon is a hole.

Therefore, Man Gui decided to pull down the bricks and make a heavy T-shaped triple earthen wall to prevent artillery fire.

Ready-made bricks are then used to build on the outside of the triad earthen wall to stabilize its structure.

However, the problem is that the adhesive needed for the wall bricks is not enough now, so he wrote a notebook and asked Chongzhen for it.

It is mainly necessary to produce a large number of oyster shells from the coast for burning into lime, which is mirage, also known as oyster ash.

Of course, Man Gui also mentioned that the mortar mixed with glutinous rice is stronger, but the cost is high, so it is impractical.

Chongzhen looked at Man Gui's recital and shook his head.

To put it bluntly, I still want money!

Fortunately, Geng Ruqi patrolled the salt in Lianghuai before, and he took out 600,000 taels of silver from the salt merchant.

There is no need to let him come back with silver, just exchange it for glutinous rice and transport it to Tongzhou.

After all, Yingchangcheng will face the baptism of the main force of Jianzhou sooner or later!
