Shangyuan Festival is the grandest festival of this era, however, the palace is a gloomy and bleak appearance, many from birth, in the palace to live a rich and comfortable life of the little princes, tomorrow will be the first time to go out, and, on weekdays, those personal servants who are obedient to them, the emperor also did not allow them to bring, just sent each of them an unknown palace maid, and a guard who did not listen to them very much, look at the posture of these two people walking, you know that they are all practitioners, It should be a secret guard trained by Li Shimin and his wife.

If they just went out and experienced the local life for a few months, they would not have such emotions, before leaving, they also received the news that the management system of the harem will be comprehensively improved, and when they come back, the maids and eunuchs who are now serving them will all be gone, that is to say, these two secret guards may be their lifelong companions.

As for those palace people, who are as careful as Empress Changsun, they naturally want to gather all of them and train them for the operation of several other commercial plazas that will open one after another, not only that, but she also ordered that the proprietors of the shops that rent commercial plazas should come out and receive training organized by the eldest grandson's family together.

If it's just Sun Xiangfu going to Shannan Road by himself, it's actually very simple, but if you add a few children who haven't woken up yet, it will be a bit noisy.

When Sun Jing woke up, he couldn't see his mother Yu Xiu'er, and he liked to cry.

When Sun Wanyu stinks, only Sun Xiangfu personally serves it.

The two little guys who are more than one year old, Sun Feng and Sun Wanyu, basically can't lose their hands, and they are stubbornly entangled with Hongmei and Chun Tao, if they come to you to play, you ignore them, all kinds of screams! Catch! Trouble! Toss you have to compromise.

Therefore, since he hit the road, Sun Xiangfu has really experienced the hard work of taking care of children.

"I knew it earlier, and I brought Xi Niang and Duan Niang too." After finally getting tired of playing with a few children and letting them sleep on the soft bed in the carriage, Sun Xiangfu said depressedly.

"As soon as the children get together, they will go to the sky, the husband is busy with official business on weekdays, and the concubines dare not let the children disturb the husband, now I know that it is not easy for the concubines!" Hongmei helped Sun Xiangfu knead the sore arm that was holding the child, and Chun Tao helped him press and bow down for too long, and his thighs were a little numb and smiled.

"With your own children, no matter how tired you are, you are happy, but with other people's children, it's different, let's go on so slowly, I'm afraid we won't be able to catch up with the rice breeding in the fields."

For the cultivation of rice, although Sun Xiangfu is no stranger at all, it is impossible to engage in hybrid rice breeding as soon as he comes up, because he first needs to find different rice varieties, and before different rice varieties are cultivated, what Sun Xiangfu has to do in the first year is actually just to teach the officials of the Ministry of Agriculture to organize field preparation, fertilization, and even cultivation of subspecies in accordance with more scientific methods.

When Sun Xiangfu came over, the hybrid rice research center where he worked had already solved the main problem of using the advantages of interspecific hybrids, and the newly bred interspecific super hybrid rice in the experimental field had large ears, many grains, and excellent quality, which was 20 percent higher than the yield of high-yield hybrid rice commonly planted before, and the yield per mu had exceeded 1,000 kilograms.

However, the yield per mu is more than 2,000 catties, in this period, Sun Xiangfu is not daring to think, although he knows the whole set of theoretical knowledge, and has participated in planting, but the current scientific and technological conditions are limited, first of all, the fertility of your field, it is impossible to reach the indicators of those experimental fields in later generations.

Therefore, if you want to increase the yield of rice, it also needs a relatively long cycle, just like he taught the children of farmers to use the quaternary seed management technology to cultivate improved wheat seeds, it takes almost a few years to achieve certain results, and then step by step, gradually push up.

Of course, since he decided to do it, he was still somewhat sure.

In the first year of Zhenguan, he opened a test field in Lingnan, planted Zhancheng rice, and achieved the result of ten stone and three stones per mu of wet weight, according to the calculation of dry rice, it should be more than eight stones and less than nine stones, count a thousand catties! Then the beaten rice should be seven or eight hundred catties.

In fact, the yield planted by ordinary people is much lower than the yield of his experimental field, and the data fed back from Jiangnan and Lingnan in the past two years show that ordinary people, even if they only take the average output of Shangtian, the dry rice produced per mu and put into storage is basically not more than six stones, only about 700 catties, and can produce more than four stones of rice, more than 500 catties, which is roughly equivalent to the level of the Ming Dynasty in later generations.

In Sun Xiangfu's view, there is still a lot of room for improvement in this yield, in an area like Dongting Lake, which is just suitable for planting two seasons of hybrid rice a year, if the three-line hybrid rice technology is used to plant, the yield per mu should be able to mention one to two percent on the previous best results.

If the conditions are ripe, it is not impossible to promote the super rice breeding program, like the first phase of super rice in China from the 96th year to the millennium, and the yield will reach more than 700 kilograms per mu.

This is because the technology that Sun Xiangfu learned to use has been three to four levels more advanced than the period of the first generation of super rice breeding, of course, it is impossible to exceed the yield of 900 kilograms per mu in the third stage, because in the third stage, molecular technology has begun to be combined with conventional breeding.

Sun Xiangfu did not use the premise of molecular technology, at most the conventional breeding technology, to the extreme, to promote it to the yield of seven or eight hundred kilograms per mu, after all, this period of one mu of land is only equivalent to a little more than eighty percent of the future generations, if the mu production capacity of 1,500 catties of dry rice, compared with his first test in Lingnan experimental field, the yield increased by about fifty percent, which is enough to shock the world.

In addition to the weight of about 20% of the chaff, the mu production capacity has ten stone of rice, even if it is impossible for ordinary people to plant to the extent of Sun Xiangfu, about seven or eight stones, it is still very likely to achieve, which is much higher than the economic value of the main grain crop wheat in Guanzhong, with this grain output, the output of one mu of land is almost enough to supply a person's staple food consumption for a year, according to each young adult only planting ten acres, two seasons a year, two million young and strong people to farm, It can properly guarantee the food rations of more than 30 million people in Datang.

Among the more than 30 million people in Datang, the real young and strong population is only about 10 million, which is equivalent to using less than 20% of the young and strong population to solve the problem of eating for everyone, so that the remaining 80% of the young and strong population can be engaged in other industries.

Of course, this expectation only exists in Sun Xiangfu's general conception, even if it is to achieve the breeding and planting of the first improved rice, the whole process will take almost four years, and it is best to have smooth weather in these four years, so as not to have any major disasters.

The convoy had just walked for a while, and then stopped, Sun Xiangfu got out of the carriage with some irritability, and asked Zhang Ke, who had returned to the team, "What's wrong." ”

"It seems that the king of Han wants to pay tribute."

"Hey, these little guys are still endless, let's discuss it, let's take your turn! Tell the attendants that when they get to the next market town, I will equip each of them with a toilet in their carriage, these little guys can pull it, and solve it directly in the carriage, without my permission, they are not allowed to stop and dump feces, and if they like to pull, let them stink all the way to Jingzhou. ”

The oldest is a group of boys who are only twelve or thirteen years old, they have emotions and don't want to go to Shannan Road, but they haven't come up with any tricks.

Now, in addition to Li Tai's kid, because he pulled everyone into the water, he was isolated by everyone and hated the same enemy, and he was quite honest, and Li Ke, the king of Shu, was able to hold his temperament, read books in the carriage, and did learning, and the other kings, especially Li You and Li Su, who were younger than these blind guys, were even more difficult to serve, Sun Xiangfu directly gave the order to the secret guards who were responsible for taking care of them, if it didn't work, they would be pumped, and they went out of Chang'an, it was a dragon, and you had to be honest in the carriage.

"Why? This king is just a compliment, why don't you Sun Zhengming allow it, even the imperial brother, don't bring such unreasonable. ”

Li Yuanchang, the king of Han, is also a little fat man, the reason why he is so fat, but also thanks to the sweets offered by Lingnan, usually he is under the care of his mother, almost live a life of obedience, this time out, he always feels that everything is not good, however, Sun Xiangfu soon let him understand, what is the power of the holy decree.

"King Han, right! Do you know what His Majesty gave me before leaving? ”

"What, what will?"

Li Yuanchang is not afraid of Sun Xiangfu, but he is still more afraid of Li Shimin, listening to Sun Xiangfu's tone, he knows that he is afraid that Li Shimin has given him some will to discipline himself as a prince, and he was suddenly a little scared, he didn't dare to resist the will, and the two chamberlains who were responsible for taking care of him didn't dare to resist the will.

"Your Majesty said, during the period of going to Shannan Province to plant rice, I will pay for the discipline of the kings, and if necessary, you can carry out the punishment of up to thirty lashes, by the way, what about my whips!"

Sun Xiangfu said, and immediately a guard lifted a red sandalwood box to the front of the car, the lid was opened, and there was a whip woven of hard cowhide with lines lying inside, such a whip can draw blood marks on the horse's buttocks, not to mention the fine skin and tender meat of these little princes.

Seeing this whip, Li Yuanchang's fat suddenly shook in fright, he recognized that this was a royal thing, but saw that Sun Xiangfu did not pick up the whip to whip his posture, but spoke again, "In addition to pumping people, I can also punish you in many projects, such as people like you who have a lot of and urine, I can punish you for not eating, not drinking water, and even punish you for doing all kinds of work, if you don't want to be punished, it's better to be honest, Shannan Road, but there are no servants recruited, laundry and cooking, it is estimated that you can't do it, It's likely that something like emptying the toilet will be done by the disobedient among you······"

"I, I, I, I'll get in the car, don't you find an excuse to punish me for no reason, otherwise, I will definitely go to my father and brother to complain."

Li Yuanchang said, and hurriedly climbed to his carriage, who expected, Sun Xiangfu continued, "I want to tell Your Majesty, I'm afraid you have to wait a few years, this rice can't be planted, you can't go back to Chang'an at all, so, it's best to be honest, otherwise, you may have to empty the toilet in Shannan Road for several years." ”

"Poof."

Li Yuanchang was so frightened by Sun Xiangfu's words that he slipped and fell directly on the carriage, and he didn't care about his aching knees, so he got into the innermost part of the carriage and didn't dare to show his head again.

At this time, Chun Tao Dao, who saw the conversation between Sun Xiangfu and Li Yuanchang in the carriage, said, "The husband went to Shannan Road to do business, why did Your Majesty hand over so many little princes to the husband to discipline?" ”

"Hey, who knows what our majesty is thinking! Perhaps, this increasing number of younger brothers and sisters has become a worry for him! ”
