Du He was infected by the old man's hearty laughter, and he also laughed, but when he heard the back, he was inexplicable, confused, and didn't know what this had to do with him, and looked at Liu Renliang suspiciously. Pen & Fun & Pavilion www.biquge.info

Liu Renliang smiled, obviously understanding the reason, but he didn't tell him.

With a full of incomprehension, Du He asked, "Uncle, why is this?" Could it be that Duhe first proposed two crops of rice? ”

"This is just one of them!" The old man looked like you were lonely and unheard, and said, "Does the young man know about the plague in Suzhou more than half a year ago?" ”

Du He smiled: "I've heard of it, it seems that with the efforts of Du He and Sun Simiao, the people of the whole city were saved!" ”

The old man looked grateful, and said emotionally: "Yes, when the plague in Suzhou was threatened, 150,000 people, including my family, were threatened, but Lord Duhedu did not give up on us at this time of crisis, regardless of his own danger, he came to our Suzhou in person, and worked tirelessly to save the lives of 150,000 of us." In our eyes, Master Du is like a living bodhisattva. When the imperial court announced the news of planting two crops of rice, few people were willing to take the risk. If we don't plant two crops of rice, we can have no worries about food and clothing, but if we fail to plant two crops of rice, we won't even have food to eat. Later, I heard that the two-crop rice was proposed by Lord Duhodu, and he came to the conclusion after investigating the terrain and climate in the south of the Yangtze River. Master Du is the reborn parent of our Suzhou people, and his proposal is naturally good for our Suzhou people. It is precisely because we believe in Lord Du that we have today's harvest. July is coming, the seedlings for the second season are ready, and now we just have to wait for the land to be ready, and we can plant the seedlings again, and when the harvest comes, my youngest son will have money to marry a daughter-in-law. ”

The old man smiled and said very ordinary things, his face full of yearning for the future.

"Young man, if you don't think you're old and long-winded, go back and tell your father and mother, so that he doesn't hesitate anymore. Today's emperor is not the tyrant Yang Guang, he is a virtuous emperor, and Lord Du is a good official who is willing to work for our people, you should believe in their policies, don't hesitate. If you miss this year, there will be next year, and you shouldn't miss it next year. ”

Du He smiled bitterly, this old man already regarded him as a farmer who came to inquire about the news, it seems that similar situations should happen repeatedly, these people have unexpectedly become the spokesperson for the promotion of two crops of rice. I couldn't imagine that some of the trivial things I did at the beginning would be remembered by the people to this day, and I really felt a little ashamed, and said with a smile: "Thank you for reminding the old man, I will!" ”

Du He smiled and said goodbye to the old man and left.

Liu Renliang took the lead in walking towards the sweet potato cultivation field and said: "If it weren't for the general who won the hearts of the people here, it would not be easy to promote these two crops of rice." ”

Du He sighed: "The cause of the past, the result of today, the original effort, in exchange for today's ending, this is for the officials to be respected and loved, or should they do practical things, people-oriented, rich people and strong country!" ”

Liu Renliang said with deep thought: "The general's sentence of 'enriching the people and strengthening the country' is more sobering than 'the country is strong and the people are rich'. ”

The two walked for several miles, and came to a field where foreign matter was planted, and the sweet potato vines that were thriving were intertwined with each other, and there was a whole acre of sparse field.

"Good! You and I imagined it better! Du He not only stroked his palms and laughed, but his expression was even more excited than the success of two crops of rice.

Liu Renliang was surprised: "General, the successful transplantation of this sweet potato can really benefit the eternal future?" It's not that Ren Liang doesn't believe in generals, it's just too unbelievable. Do you know how Zhao Hui grows these sweet potatoes? He first fills the manure tank, then buries the sweet potatoes on top of the manure tank and grows them into seedlings. After the seedlings grew up, he cut the seedlings directly and then inserted them into the ground, without even needing roots, this planting method is really unprecedented, incredible. ”

Du He's eyes lit up, and he was overjoyed, it seemed that he was not entrusted. He had seen the cultivation of sweet potato seedlings in the countryside, which was not much different from the method used by Zhao Hui. Because the sweet potato vine is extremely tenacious, like a cactus, if you break off a piece and plant it in the soil, it can still survive.

The same is true for planting sweet potatoes, as long as you cultivate sweet potato vines, you can directly use sweet potato vines to make seedlings, as long as the sweet potato vines are inserted into the soil, it can survive and grow in a harsh environment, precisely because it has this vigorous vitality and easy to cultivate characteristics. Therefore, sweet potatoes are suitable for cultivation in any terrain, even on high slopes of loess.

He listened to Liu Renliang's disbelief on his face, and said with a smile: "Wait, the facts will prove everything." Sweet potatoes are harvested twice a year, and one acre of fertile soil produces two or three thousand catties of food, which is more than enough. "In fact, in the new varieties of later generations, the yield of sweet potatoes is not to mention two or three thousand catties, and fifteen thousand catties are all fluttering things.

However, Du He did not know what kind of sweet potato he brought from the Indians, so he did not dare to say so completely. But despite this, it is also an astronomical amount. Because the average yield of rice per mu of land in the Tang Dynasty was only one stone, and one stone was only equal to less than three hundred and fifty catties, it is conceivable that if the sweet potato is successfully cultivated, what kind of development will it bring to the agriculture of the Tang Dynasty.

It is completely certain that the successful planting of sweet potatoes can ensure that the Tang Dynasty will no longer worry about military rations in the future, even if it is a remote place to go to Goguryeo.

Liu Renliang made the numbers in Du He's mouth speechless.

There is no shadow of Zhao Hui in this field, presumably he is training sailors in the port of Shanghai.

The two also ended their private visit to Weifu, returned to Suzhou, changed their clothes, had lunch, and rode to the port of Shanghai together.

The Shanghai of the Tang Dynasty is very different from the Shanghai of later generations, and it cannot be compared.

As the largest city on the mainland in later generations, a prosperous place of economic, financial, trade and shipping centers, it was still a small fishing village at this moment, with a radius of only one mile. Due to the need for construction, more than 30 households in the fishing village have moved out under the persuasion of Liu Renliang.

Today's Shanghai is a barren area where there is only officer training, and no one has any human relations.

Du He stood on the bank of the Huangpu River in Shanghai, looking at this place where dogs don't poop and birds don't lay eggs, and couldn't help but smile bitterly, this place is so fucking barren.

Liu Ren Orbit: "This place in Shanghai has little to offer except for the construction of a wharf. ”

Although Du He was surprised by the barrenness of Shanghai, he smiled confidently: "It is enough to have this advantage, the future shipping is bound to be the general trend, Shanghai with convenient ports, as long as the Silk Road on the sea, the expansion is successful, I can guarantee that within a hundred years, it will replace Suzhou and become the largest metropolis in the south of the Yangtze River." ”

Only he, who is familiar with the general trend of history, dares to let go of this wild talk.

When he came to the dock, Zhao Hui was teaching the five hundred people in the open space, he took the ring ruler, gestured on a wooden board, and wrote down some knowledge of navigation from time to time, with a rigorous and serious attitude, and he didn't even notice the arrival of the two of them.

Du He and Liu Renliang didn't bother, they just watched from the sidelines.

It wasn't until the end of class that Zhao Hui discovered the existence of the two of them, and hurriedly stepped forward to say hello.

Du He smiled and quipped: "I didn't expect Brother Zhao to really have the talent to be a teacher." ”

When Zhao Hui was in Longmen, Jiangzhou, he didn't know Du He's identity, but now that he has lived in the Tang Army for half a year, he still doesn't know Du He's status in the Tang Dynasty, so he hurriedly saluted, saying that the brothers are commensurate, and they dare not be ashamed.

Du He is not reluctant, which is very important in the upper and lower ranks of the army.

is as close as Luo Tong and Fang bereaved love, when Du He gave the order, he was also commensurate with the general, and he was not allowed to call Qinglian and the eldest brother.

Zhao replied: "It's all some small experiences, but don't look at these small experiences, after driving at sea, these small experiences are often life-saving." ”

Du He asked Zhao Hui to take him on a tour of their military camp, and Zhao Hui laid out his reverie one by one: how to distribute the sailors. How to assign craftsmen who repair ships. How to assign medical personnel and so on, everything is mastered in detail, and it is very well organized, which is breathtaking.

During the visit, Du He found that the eyes of the generals looking at Zhao Hui were full of respect, which was the attitude of absolute obedience to his commander, and he said: "It seems that this Zhao Hui is not only an excellent captain, but also an excellent general who can be admired by the soldiers under his command." ”

Zhao Hui rubbed his fists and said, "General Du, when do you think we can sail to sea?" ”

Du He was surprised: "Is everything ready?" ”

Zhao Hui smiled confidently: "Everything that should be taught has been taught, and the people assigned to me by the general are all brave warriors, who are completely able to deal with all dangers, and the difference is only experience." This experience must be improved through sailing. In the end, he intends to sail in the nearby waters, first make friends with the friends of the leading countries, open commercial shipping routes, and then start a long voyage when he is fully prepared. In fact, in the last days, they will pass through many countries, they are far less developed than my Datang, but they have many things that our Datang does not have, and they should be happy to trade with us. ”

A trace of excitement flashed on Du He's face, the day of opening up the sea for Datang was finally coming, and he said with a smile: "In a few days, you can meet Your Majesty with me, and after Your Majesty agrees to give you the documents to be good with various countries, you can start sailing...... However, the sweet potato thing can't be pulled down! ”

In Du He's eyes, sweet potatoes still occupy a very heavy portion.

Zhao replied: "This point will be prepared for a long time, when he planted sweet potatoes, he has already handed over all the skills to reliable farmers, and now he is taking care of the sweet potato fields, with him, there will be no problems." ”

"That's good!"

Du He did not stay in Jiangnan for a long time this time, less than a month, after dealing with three major events, he visited all parts of Jiangnan, recorded the actual situation truthfully, and led Zhao Hui back to Chang'an.

When he stepped into Chang'an again, it was already late August, less than ten days before the wedding in September.
