Zhu Yu stood not far away, watching a group of genius students from the Beijing Normal University Hall squatting under the locust tree, smoking dry cigarettes one by one.

Dunhou smiled.

Zhu Yu also went to the sulfuric acid laboratory, which was ridiculed as a bald laboratory, and the genius students in it were competing to do experiments day and night, and even the thatched house felt that it was a waste of time.

Agricultural students are slow, chemical engineering students are fast.

The contrast is striking.

But Zhu Yujue's slowness is fast.

It is the hope of the Ming Dynasty and the future of the nation.

Zhu Yu walked over to find Song Shihui, who was silently smoking dry cigarettes, and briefly elaborated on some of the situations in Miyun County.

Song Shihui put down the cigarette pouch and knocked it on the stone mill next to him, knocked the cigarette ash in the cigarette pouch pot, stuck it in his waist and walked to a cement house in the middle of the field.

That is the result of Song Shihui's hard work over the years.

Gene pool.

The hybrid hybrid rice needs enough rice seeds to be cultivated.

There are fifteen varieties of rice alone, including indica, glutinous, japonica and other varieties, and even a drought-tolerant hybrid rice has been cultivated.

There are also seeds such as wheat, beans, and wheat, and that small cement house carries the food and clothing of the people of the Ming Dynasty.

Song Shihui has cultivated the high-yielding rice Song Mi No. 7.

The yield per mu is 600 catties.

With scientific planting and high-quality fertilizer, the yield per mu can reach a yield that even a god can't do.

The yield per mu is 1,000 catties.

Song Shihui took out two small pockets from inside, handed them to the agricultural students next to her, walked to Zhu Yu and didn't speak, and looked at the hybrid field planted with various crops in silence.

The farming custom of Beizhili is winter wheat and summer rice, and these two small pockets contain Song Mi No. 7 with a yield of 1,000 catties per mu and Songmai No. 7 with a yield of 800 catties per mu respectively.

Originally, I wanted to give my teacher a surprise, but my uncle Zhu Yu said that he would go to Miyun County to promote it first.

But there is a problem that has always troubled Song Shihui, the degradation of improved seeds.

Although the yield of hybrid rice with a yield of 600 catties per mu is very high, high-yield rice will be degraded due to problems such as individual genetics and offspring separation.

At most, it will degenerate into the low-yielding rice of the past, and a batch of high-yielding hybrid rice will be replaced every summer sowing.

It doesn't hurt to change rice seeds, many people have to buy rice seeds and wheat seeds by borrowing every year, and only need to establish a seed company to solve this problem.

The establishment of a seed company prevented the leakage of improved seeds, and secondly, it could also save the common people from being harmed by the bureaucrats and gentry.

Zhu Yu came over to ask Song Shihui to help promote potatoes, and when he heard him say that this kind of rice yields 600 catties per mu, his eyes widened on the spot.

It also made Zhu Yu completely relieved.

A sentence of promotion is simple to say, but it is extremely difficult.

The people of Miyun County have planted grains for many lifetimes and have never read books, so it is difficult for them to accept foreign things, especially the grain planting that is related to whether the family can survive.

Even if someone wants to plant potatoes, they won't plant potatoes in the first place, which will make the people who have moved their minds retreat.

No matter how high the yield is, if you don't know how to serve, you won't be able to grow food.

The common people are not big squires who have endless food, and they are busy all year round, and the food they grow is not enough, where will they open up a field to plant potatoes that they can't grow.

These are secondary, and the most difficult thing is how to change the people's closed and conservative thinking, as long as some things are deeply rooted in the hearts of the people, it is difficult to change them.

It is no less difficult to change the farming methods that have been adhered to for generations than to keep the people from worshipping in the ancestral hall.

The eldest brother Zhu Shun was able to promote it successfully, firstly, because of the great kindness of the people, and secondly, the common people after the catastrophe had no way to live, so it was better to repay this kindness.

Even so, Song Yingjing personally presided over the government affairs of potato promotion, but also encountered many practical problems, and many times it was necessary to dispatch officers and soldiers from the inspection department.

Under the promise of the Song family that as long as they can't grow grain, the Song family will still open a porridge factory next year, so that potatoes can be promoted in such a short period of time.

Zhu Yu immediately dragged Song Shihui out of here, ordered someone to go to the Beijing Normal University Hall to bring two fast horses, and rushed to Miyun County.

A few days later, the students of Jingshi University drove a mule cart and brought enough 1,000 acres of fertile land to plant Songmi No. 7 and Songmai No. 7.

Zhu Yu took Song Shihui to the only remaining 1,000 acres of official land in Miyun County, and the two stood on the ground, looking at the fields with strange shapes.

Song Shihui, who was taciturn, suddenly changed her words: "If you want to really grow high-yield rice, the first thing to change is not good seeds, but scientific planting methods." ”

"This includes hydrological surveying and mapping, water conservancy construction, soil improvement and other issues, we can't grow high-yield rice in the first year, we need to solve these problems first, before we can plant high-yield rice."

"Hydrological surveying and mapping has been handed over to my nephew, but this water conservancy project needs a large amount of silver, and my uncle needs to go to the imperial court to ask for silver, or to find the squires to raise donations."

When Zhu Yu heard that he was going to ask the court for silver, he smiled bitterly, the court lacked nothing but silver, and it was estimated that there was no hope.

As for finding the gentry to raise donations in the name of building water conservancy, it is even more impossible, and every time the county government issues a notice saying that the construction of water conservancy is actually a means of looting the people's fat and ointment.

The squire took the lead in donating first, and then divided the account fifty-fifty afterwards.

If you want these squires to donate money, you can also settle the matter of splitting the account first.

Zhu Yu patted Song Shihui on the shoulder and said, "Shihui, you go to measure the hydrology first, and Uncle will solve the matter of silver." ”

is finally about to start promoting the results of these years, but Song Shihui and the agricultural students behaved a little strangely, just squatting on the ground and silently smoking a pot of dry tobacco, and getting up to do things.

It's not that they don't want to be excited, this group of students from Beijing Normal University who are working silently for the future of the nation have been forgotten for too long.

I don't remember what excitement was anymore.

Song Shihui took the county chronicle of the county, looked at it twice, only who had a person in the family, and who donated a few taels of silver in the construction of water conservancy, and returned the county chronicle to the white-haired scribe: "It is full of county chronicles bought by the squires with silver." ”

"There is no record of the annual precipitation, maximum precipitation, rain-free period, and the most important drought and flood situation in Miyun County."

"The next year will be very hard, you write a letter to your family first, we have been living here for the past few years."

None of the agricultural students quit complaining about being tired, put away the cigarette pouch pole, and walked silently to the simple pergola on the ground to write letters to their families.

Zhu Yu, who was next to him, decided to talk to the local squires, hoping that they could donate some silver, after all, it would be good for them to build a water conservancy.
