The matter of re-entering the rice scale was dealt with in one day, and Du Wei ran back happily and wrote a big-character list by hand, but although the words were well written, I am afraid that not many people could understand it, and they had to be helped by these officials to read it to the victims.

"Lord Shangshu, the calculated average yield per mu is nine stone three, this is dry rice, nine stone three!"

"It's just nine stones and three stones, what are you excited about, compared to when I planted rice for the first time in Lingnan, it didn't increase much, it seems that this yield is basically a limit before the improvement of rice seeds."

This planting, from the scientific field preparation, to the use of the best fertilization program that can be done during this period, to the higher efficiency of insect control, weed control, can be more than the first time in Lingnan, let the Lingnan people who do not know how to plant rice at all, put in more effort, but the average yield per mu has only increased by 0.3 stones, that is, more than 30 catties.

According to Sun Xiangfusun's analysis, it is not a problem of planting technology, because the planting technology is almost impeccable, which is the limitation of rice genetics.

Previously, in order to facilitate comparison, he calculated and compared the size of the acres of trial planting according to the acres of later generations.

If it is only about nine stone three or 1,100 catties per mu, then he wants to end the first phase of research and planting and reach the yield of the first phase of hybrid rice research and trial planting in later generations, but there is a gap of nearly 300 catties to catch up.

In four years, through continuous hybridization, optimize the genetics of rice seeds, and increase the average yield per mu by nearly 300 catties, which is very difficult.

Although Sun Xiangfu looked down on this yield of 1,100 catties per mu, this output was enough for the people in the fields to beat gongs and drums to celebrate.

Last year, they themselves, only planted five stone four yield, now this yield in their opinion is more magical, Sun Xiangfu is really the first person in the world to farm, the same field, let him plant, the yield per mu actually increased by nearly four stones, with each family almost twenty-five acres of rice field to calculate, this is to increase the yield of nearly 100 stone rice in each household's field, then, the income from selling grain, almost increased by six times. If that's the case for both seasons, that's twelve.

Many older old farmers, when the officials of the Ministry of Agriculture helped them settle the account, they were excited to tears, they could never have imagined that in their lifetime, they would actually see the scene of planting more than 20 acres of land, and they could earn more than 20 yuan a year, this is really a developed rhythm!

There are people who are happier than the people, it seems that there are others, that is Li Tai and their princes, when they walked through the cheers of the people, they all held their chests high, it seems that this credit is theirs, but they don't know that until now, they haven't remembered all the procedures and precautions for planting rice!

The first time planting, Sun Xiangfu just exercised their hands-on ability a little, so that those northerners who had never seen how rice was grown, had a general understanding of what was going on with rice planting, and the whole process, they just did some dispensable physical work, these things, just let a village child do it, maybe they are better than them.

However, when they were proud and later learned that Sun Xiangfu had no intention of taking them to Dingxiang, they were struck by lightning one by one.

"Why? Why? Now that the rice has been planted and the yield is so high, why don't you let us go to Dingxiang······?"

"Based on what you just said, you are not qualified enough to make a decision. Rice seed research, this is just the beginning! You actually think that this is a finished product, I want to ask you, how to grow rice, do you really know? Can any of you tell me how to soak rice seeds? ”

"Uh······"

In the small courtyard where Sun Xiangfu lived, a group of princes who hurried in were speechless when they were just asked a question from him, and Wu Meiniang, who was playing with Sun Jing on the side, still looked at them with a gloating look, but let the smarter Li Tai find an excuse and pointed to Wu Meiniang, "Then why can she go?" ”

"Her basic theoretical knowledge has been learned, and she is going to go to Shanyang's Agricultural College to learn her hands-on ability for one to two years, your age is several years older than her, but now, the hands-on ability is a mess, and the theoretical knowledge has not yet been introduced. It's also a shame that you're embarrassed to talk about others.

In the next month, you go to the field every morning and evening to take care of the crops, and when it is hot at noon, follow Mei Niang to learn the basic theoretical knowledge, if this season of rice is planted, you can't even soak the seeds, prepare the field, fertilize these basic things for planting rice, I think you can't even see the next sports conference. ”

Thinking that Li Shimin might take the school examination for his own people, Li Tai regained his senses and realized how careless he had learned in the previous few months, and most of the time, he focused on solving the problem of having a full stomach, but it was really a failure.

Hearing that she wanted them to learn theoretical knowledge with her, Wu Meiniang's expression was wonderful, and she was promoted to a little teacher, and a lot of tricks for these princes popped up in her mind, but she saw Sun Xiangfu turn his head to her with a straight face and said, "If you don't care, teach them crookedly, be careful that I will leave you with Shanyang for the rest of your life to teach the Hu people to farm." ”

"Hah~"

Wu Meiniang was depressed, but Sun Xiangfu didn't have any meaning to take back this sentence, Sun Xiangfu asked her to teach Li Tai them, in fact, it was also useful, after learning the basic theoretical knowledge, when teaching others, he would often reorganize the knowledge and eat more thoroughly, Sun Deshou and others were the same at the beginning, now, they basically don't need Sun Xiangfu how to teach, they can do some breeding, hybrid experiments, and can also slightly improve the planting methods of some crops according to the time and geographical environment, Every once in a while, there will be some new breakthroughs, and Sun Xiangfu will let them grow on their own.

"Starting tomorrow, you will have to do the work of preparing the fields and draining the fertilizer, and the dung ······ that hundreds of thousands of people on the construction site have saved in the past few months."

When Sun Xiangfu said this, Li Tai and the others were shocked again, farming, they couldn't escape from dealing with these things, and their hard days were coming again.

"When you encounter difficulties, don't feel afraid, learn to face them, temper your will, and make yourself stronger, understand?"

Under Sun Xiangfu's encouragement, Li Tai and the others withdrew from the small courtyard with a bitter face, and before they could take two steps away, they heard Wu Meiniang in the courtyard ask Sun Xiangfu, "What about after they become stronger?" ”

"After that? Of course, I got used to doing these more difficult things. ”

Li Tai and the others only felt that the soles of their feet were very slippery and were about to fall to the ground.

Wu Meiniang's silver bell-like laughter came from the courtyard, and she felt that she should drain more fertilizer this season and apply all the newly developed fields.

"Go and ask your two ladies to carry the basket, and let's go to the pond to pick water chestnuts."

Sun Xiangfu handed over some simple things to Li Tai as much as possible to do, in addition to being able to take leisure and take care of more children, in fact, he was exercising Li Tai's grassroots organization ability, with their identity, where would it really be their turn to do those dirty and smelly jobs, they only needed to know when and what the people under the organization would do, and they would be able to benefit one party very well, after all, they were all the princes, and in the future, at least they would do the positions above the state assassin history.

Soon, Hongmei and Chun Tao each twisted a basket out, Sun Jing heard that they were going out, and ran out of the house, Sun Wanting, who had two long strings of gardenias on her braids, was holding a pink paper umbrella, for fear that the sun would burn the gardenia on her head.

Wu Meiniang came out last, one left and one right, holding Sun Feng and Sun Wanyu, who were almost two years old, with both hands, according to the usual practice, in the end she should only hold Sun Feng, because Sun Wanyu will definitely ask for a hug when she sees her father empty-handed, and Sun Xiangfu rarely refuses this child who looks most like herself.

"Let's go, let's go, Daddy, this time, I'm going to row."

Sun Jing jumped out of the yard first, and ran to the main canal next to the road in front of the door, over there, there were a lot of canopy boats that could row to the lotus root pond and water chestnut pond, but if he really wanted to row the boat, it was estimated that he would not be able to reach it tomorrow.

"Slow down, don't go into the river." Zhang Ke, who was on duty outside the house, would catch up as soon as he saw Sun Jing, the kid running out.

Most of the area in the ditch is rice fields, and the irrigation ditches are naturally dense, so he is afraid that children who love to play with water will fall into the ditch and have an accident.

However, it is precisely because the children here can come into contact with water at any time, so they will practice the water very well since they were young, and the later Sun Xiangfu is a person who can swim two thousand meters breaststroke and two hours of backstroke without feeling laborious.

"Lele, don't make trouble, after picking water chestnuts, Daddy will teach you to swim."

"Swim like a frog?"

"Yes."

"Daddy, Daddy, Huanhuan wants to swim too. Like a frog. ”

"Wet your hair when swimming, do you want your pretty braids and gardenias?"

"Ah~ Then I don't want to swim."

In the hot summer, swimming in the clear river is the best way to relieve the heat, and at dusk, no one will take a bath with hot water, but directly in the big canal in front of the door, even most of the village girls are like this, but they will wear clothes.

Sun Jing and Sun Wanting had seen Sun Xiangfu's strange way of swimming early on, but they couldn't learn it after a few days, especially Sun Jing, who liked to play in the water the most, and went into the water, but he was so nervous that he had been studying for more than a month, and he only dared to close his eyes and pinch his nose to stay below the surface of the water for a few seconds.

On the canopy, Hongmei and Chuntao took care of Sun Jing, who was going to row with a small pulp, Zhang Ke used a penny to prop up the boat quickly, and Sun Xiangfu, who was sitting on the bow of the boat and blowing the wind, was in a good mood, and once again hummed a folk song that he often hummed in the past few days.

"The two of us rowed a boat to pick red lings, we have to have a heart, we have to have a sister, just like two horned lings, never separated, we have one heart······"

Sun Xiangfu's singing voice, only Hongmei and Chuntao feel it the most, because they are adults and know how to love love, but they are limited to the limited level of singing skills, and they can't sing with Sun Xiangfu like Yu Xiuer.

As for the reason why Sun Xiangfu was in a good mood, it was naturally because of the good news he had been waiting for for a long time, Zhao Long drove the new ship with a steel structure keel to complete the first sea voyage, and on the way, he even encountered a large wind and waves, but he came back intact.

According to the news he sent back from the letter, this kind of steel structure keel, covered steel plate ship, due to the weight of the ship, draft, far stronger than the wooden ship in the sea wind resistance, although the speed of navigation has decreased a lot, but the safety, is improved a lot of levels, after coming back, they only need to do some small comfort, and practical design adjustments, you can start mass production, he is very confident, drive such a ship, go to a farther place.

That is to say, at most, after a year or two, he can get some South American species he wants, and with those things, the disaster resistance of the people of Datang has really risen to a higher level.
