In addition to the human exchanges, Zhou Bai's stay in the county for so long was not in vain. He brought back a total of 1,500 taels of silver.

Suihanji has been sold simultaneously in one county and seven counties. The current sales situation is good, so Zhou Bai was able to advance a dividend of one thousand taels of silver.

In addition, Zhou Bai also received the bounty from Ji Hongzhe that the imperial court had just issued for the suppression of bandits. The fifteen bandits who killed the bandits received not only titles, but also rewards that had been clearly stipulated all along.

In addition to the famous green forest giants, these Jin cavalry who act as horse thieves are all worth thirty taels each.

There was a bounty of 450 taels, plus an additional 50 taels for rescuing Hu Yanhe, a "rich businessman" who was robbed. The court was encouraging.

One thousand five hundred taels of silver is enough to support the inner government for a period of time anyway. After all, the soldiers who protect the village are only provided with food and shelter, and have not yet received their salaries.

After receiving financial support, the inner government immediately expanded its manpower because Zhou Bai had too many plans for the future.

In addition to the civil servants Tong Sheng served as, Chen Zhongbang established a new Agricultural Bureau and Tiangong Institute at Zhou Bai's request, and recruited a considerable number of farming experts and craftsmen in the Yingtian Department.

The selection criteria for farming experts are old farmers who have produced the most outstanding grain harvests in previous years, and young people who have been educated and can read, but have been rolling in the fields since childhood.

The combination of the two can provide pertinent suggestions for the development of the Agricultural Bureau. There are not many types of sweet potatoes, corns, and potatoes, and they need careful attention from the Agricultural Bureau.

With just one harvest, there will be enough seeds to spread in new fields next year.

There is also hybrid rice, and Zhou Bai will not let it go in this life.

Yuan Shengke of Blue Star explained the principles of hybrid rice very clearly. Because of admiration and good biology, Zhou Bai happened to remember how to cultivate the first generation of hybrid rice.

It's just that Zhou Bai had to discuss the male sterility of rice with the farmers from the Agriculture Bureau for three days and three nights before he could explain it to them.

The old farmers were speechless. The clan leader really said it was so complicated. Are you still worried that they would not recognize male flowers and female flowers?

They can tell the difference just by looking at the size of the flower.

Finally, the Agriculture Bureau summarized a complete process, which is to remove immature male flowers when the rice flowers bloom to prevent self-fertilization.

At this time, the remaining female flowers can be used as female parents and crossed with other male parents to produce hybrids.

In order to get more hybrid varieties, Zhou Bai specifically told Chen Zhongbang not to be afraid of spending money and to buy rice from the southern states. Their northern rice was only drought-resistant, but its yield was much worse than that of southern rice.

The goal of northern hybrid rice is to produce high-yield rice in dry fields with as little irrigation as possible.

Of course, when it comes to how to increase grain yields, Zhou Bai still has a way to test it in Tiangongyuan, and that is the chemical fertilizer that time travelers always have.

Nowadays, because the Tiangong Institute of Technology does not have any outstanding craftsmen, it does not insist on climbing any firearms technology tree, and has temporarily stopped at collecting saltpeter and sulfur.

Now Zhou Bai only asked them to study two things, one is chemical fertilizer, and the other is brewing high-alcohol wine.

Zhou Bai can provide them with ideas in both directions. Nitrogen fertilizer and phosphorus fertilizer, then find someone who has such a thing and try them one by one.

Cow dung, soybeans, plaster of paris; urine, plaster of paris, water... closed fermentation.

Anyway, several combinations are given, one by one, and in the end which one is more effective and popular.

As for high-quality wine, although Zhou Bai doesn't drink and doesn't know how to brew it, he knows how to purify it.

It's nothing more than re-distillation of low-alcohol wine, and paying attention to the distillation process when making wine.

The northern region is relatively cold, so there is no shortage of spirits, but because food is precious, people tend not to waste too much on making wine.

As long as Zhou Bai can perform the combination of punches well, the Zhou family will not be short of food in the future. In this way, they can also brew high-quality food wine and plunder many gold and silver treasures from the cold northern country.

…

More than a month later.

Next to Zhou Bai's own manor, there are now many more houses, as well as some yards surrounded by fences and bricks.

With the school grounds as the core, including the surrounding fields, it has become the exclusive base of the inner government. The village guard team strictly patrols and does not allow anyone to enter.

On the beach surrounded by streams, a comprehensive experimental field was circled here. Zhou Bai estimated that the time was almost up, so he took a group of confidants to the experimental field to check it out.

Wang Liangtian is now very high-spirited. Because of his relationship with Uncle Fu and the fact that he has done what Zhou Bai told him, he is now the field envoy of the Agricultural Bureau.

He manages a group of veteran farmers and receives not only a monthly salary but also performance bonuses.

Today, when Zhou Bai came to inspect, it was not only about his own bonus, but also about whether he could earn bonuses for his old brothers.

There are so many juniors in Yingtian Hall who want to make progress every day, which puts him under a lot of pressure.

However, Wang Liangtian was still very confident in his work and was not timid in the face of difficulties. He stepped forward to introduce the experimental fields to Zhou Bai and the others very diligently and loudly.

"My boss, Mr. Chen, look, these ten acres of rice fields have not been fertilized with chemical fertilizers, while the ten acres here have been fertilized with a generation of chemical fertilizers in advance."

"The testing of second-generation chemical fertilizers cannot keep up with spring planting. We have already conducted separate tests on the corn fields on the other side. You see, these foreign grain varieties are not acclimated to the soil at all."

"And here, the same is true for sweet potatoes and potatoes. They are all done according to your instructions. They are called whatever they are called. There must be comparison!"

Looking around, the wilderness is green and lush, but the plants in the fertilizer field are obviously half a head taller and taller, and the rice flowers are obviously blooming more fully.

The expression of luck in the foundation of farmland is also very straightforward. If ten acres of ordinary rice fields reveal traces of light and floating luck, then ten acres of chemical fertilizer rice fields reveal more solid luck.

The wisps of white air seemed to have noticed Zhou Bai's arrival and swarmed in. They gathered under the clouds, like a thick base dragging the tower above.

Such a performance of luck means that his experiment was successful and he did nothing wrong.

The use of grains and fertilizers in the country is an important weapon for him to achieve his great cause in the future, and is a "heavy treasure" that can solidify the foundation of his luck.

Chen Zhongbang picked up the rice plants in the two rice fields and compared them carefully. He took a breath of air and was keenly aware of the value.

This can at least increase production by 30%. If third- and fourth-generation fertilizers are developed in the future, 50% is also foreseeable.

"My lord is wise, these secrets must not be leaked, at least according to your plan, not in the next few years." Chen Zhongbang praised the wiseness with his hands, while scanning the men who came behind him.

At first, Chen Zhongbang didn't understand why Zhou Bai sent troops to guard the farmland. This was not a waste of manpower. Now he finally understood why the lord was the lord.

"Well, record, the confidentiality level will be raised to one level, the formula can only be known to five people, but anyone who leaks it will be dealt with according to family law."

"The Agricultural Bureau's experimental fields are well maintained and will be credited with third-class collective merit once. Tiangong Institute's merit in developing chemical fertilizers will be credited with third-class collective merit once. This month's bonuses will be paid in full."

At this point, the big farming calculation has taken shape.

Zhou Yuan, who had been silent all this time, became anxious and stepped forward with clasped fists and asked for a fight: "Master, our village protection team should also give us a chance to make meritorious deeds. The county government has just issued an order to suppress bandits, don't you think so?"
