After Duoduo retreated, Zhu Cilang ended the imperial army and led his personal army back to Nanjing.

No country can be without a king for a day, especially without a supervisor handling government affairs.

These important memorials in the past days were drafted by cabinet tickets and sent to the Shandong front line quickly, and Zhu Cilang Yu Xing reviewed Zhu.

But this is not a long-term solution after all, and the emperor should still be in charge of the capital and make the subjects all over the world feel at ease.

There is Gao Jie in Shandong, and Qin Gongming is enough.

After returning to the palace, Zhu Cilang was not idle, but summoned Lu Zhenfei, Gao Hongtu and others to analyze the Shandong war.

Although the Shandong War ended with the Qing army retreating, the whole process was not easy.

Although the Qing army had no choice but to do anything to the bastion group, they filled the trenches and broke through the trenches and directly came to the city.

This is caused by a combination of multiple factors.

First, the specific people did not understand Zhu Cilang's intentions properly, and only regarded the trenches as a tool to delay the advancement of the Qing army.

In fact, the real essence of the trench is that it can provide quick and effective support and block the enemy's attack with dynamic defense.

However, in the Battle of Shandong, the communication and support between the various sections of the trench was insufficient, which led to the Qing army finding a key breakthrough.

This is an aspect that needs to be improved in the future.

Secondly, there are also problems with the location of the trench excavation.

The Ming army chose to dig the trenches as the connecting line between the trenches, which led to the limited support for the trenches on both wings when the Qing army filled the trenches.

If the trenches are dug into arches and excavated at multiple levels, the coverage area of ​​the bastion can be larger and the support will be given.

These are all lessons learned.

Zhu Cilang never thought that he could defeat the Qing Dynasty overnight.

Even this new defense method needs to be tested in practice.

Doesn’t this reveal the problem?

It is not terrible to expose problems. As long as you can learn lessons and improve them based on them, you will make progress.

Tactics are dead, people live.

Through continuous improvement, I believe that the Ming army will become more and more at ease in the fight against the Qing army.

Of course, there are still many things worthy of recognition.

For example, the use of a six-pound cannon and a twelve-pound cannon.

This new type of artillery has proven to be stronger than the Red Cannon in many ways.

For example, the rate of fire, such as the loading method, the loading speed.

Even the most proud power of the Red Cannon is no stronger than the twelve-pound cannon.

As for the enemy of ten thousand people, the bombing of cannons shone brightly, killing and injuring countless Qing troops.

Zhu Cilang was very pleased that the establishment of the Firearms Department had achieved results.

Of course, good things need to be rewarded. Zhu Cilang ordered Gao Hongtu to continue his efforts to strive to equip the entire Ming army with new muskets and cannons.

After the two left, Zhu Cilang moved to the Imperial Garden.

Of course, he did not come to appreciate flowers and plants, but inspected an important task.

At this moment, the Royal Garden garden gardens have been completely demolished and the land has been plowed.

It can be said that the entire Imperial Garden is now a piece of farmland.

There are two kinds of potatoes and sweet potatoes planted in the farmland.

Needless to say, potatoes have a more well-known name for sweet potatoes.

Whether it is potatoes or sweet potatoes, they were introduced to the Ming Dynasty in the late Wanli period.

However, neither of these two things were officially promoted, and it was not until the reign of Emperor Kangxi of the Qing Dynasty that they were planted on a large scale.

As we all know, the late Ming Dynasty encountered the Little Ice Age with the most severe climatic conditions.

The weather was extremely cold during this period, and the drought was severe in the whole north, which caused famine, which led to the surging peasant uprising during the Chongzhen period.

In the end, Beijing was captured by Li Zicheng, and the Qing Dynasty took advantage of the conflict between Wu Sangui and Li Zicheng to benefit, and took the opportunity to enter the pass and steal the fruits of victory and pick peaches in vain.

From meteorological analysis, the climate gradually warmed up after Shunzhi, and the Little Glacier completely ended during the Kangxi period.

The so-called "Kang Gan Prosperity" is just because the little ice river ends, and God is just admiring his face.

Of course, in addition to this, large-scale promotion of potatoes, sweet potatoes and even corn is also very important.

In the feudal era, letting the people have enough food was the most important thing.

Because land annexation cannot be solved by all dynasties, large-scale peasant uprisings will break out at a certain stage.

The Qing Dynasty relied on the large-scale promotion and planting of potatoes, sweet potatoes and corn to solve the problem of people's food, which led to the so-called "Kang Gan Prosperity".

If the land is not enough, the output will be collected.

During the Qing Dynasty, most of the land was also in the hands of landlords. The population from tens of millions in the late Ming Dynasty to hundreds of millions in the late Qing Dynasty. Of course, there is no other reason. High yield crops are the only reason.

Since the Qing Dynasty could promote potatoes, sweet potatoes, corn, and Zhu Cilang, it would be natural.

However, as the first batch of experimental products, Zhu Cilang is preparing to try the cultivation of potatoes and sweet potatoes first.

This is mainly because the planting time of potatoes and sweet potatoes is close.

Potatoes are usually planted in February or March and harvested in May and June.

Sweet potatoes are planted in mid-to-late April and harvested in September and October.

Now potatoes have been planted for more than two months, while sweet potatoes have just been planted.

As for corn, you should choose to sow after mid-May at least.

In order to stagger the time, Zhu Cilang chose to sow summer, that is, sow corn in June, so that he should be able to harvest in October.

Among these three drought-tolerant and high-yield crops, Zhu Cilang is most optimistic about potatoes and corn. The main reason is that the growth cycle of these two crops is shorter, while sweet potatoes require relatively long time to grow.

Of course, these three crops, Zhu Cilang, will do their best to promote them. It is just a difference in time.

First try to promote potatoes, followed by sweet potatoes and corn.

As long as the people's food problem is solved and the demographic dividend is obtained, the number of people alone can crush the Qing Dynasty.

Relatively speaking, the north is more suitable for planting these three high-yield crops. However, this does not mean that the south cannot be planted.

Guizhou and Yunnan are very suitable for growing potatoes and sweet potatoes. As for Sichuan, it can also promote seeds on a large scale.

It is better to plant rice in Huguang, Jiangxi and other places. After all, it is impossible for a country to survive by relying solely on potatoes, sweet potatoes and corn. It is still necessary to provide appropriate rice reserves.

The potatoes will be harvested in one or two months. Zhu Cilang really wants to see how much the first batch of potatoes cultivated can produce.

Although he knew that the per mu of potato yield beat all the crops of this era, he was really unsure of the actual yield.

But Zhu Cilang had already made up his mind that as long as the actual per mu of potatoes were justified, he would immediately issue a large-scale promotion.
