Before entering this world, Shen Long not only read a lot of information, but also personally went to the Western Regions for field investigations, and he couldn't be clearer about what crops are suitable for planting here, and the northern foot of the Tianshan Mountains grows more cotton, tomatoes, corn, potatoes, sweet potatoes and wheat, among which cotton cannot be eaten, and it is not suitable for planting too much for the time being, and the rest can be planted here.

It's just that corn, potatoes, sweet potatoes and tomatoes have not yet entered China, so these soldiers from peasant families do not know each other.

In this regard, Shen Long has been prepared for a long time, he has already asked people to cook some of each new crop, farmers have always been cautious about new crops, they will never plant this kind of thing before they are not sure that this kind of thing can be eaten and have a good harvest, only when they taste the taste of these crops with their own mouths, they will be tempted.

Although for the Tang Dynasty, each of these good seeds brought by later generations was extremely valuable, in order to convince these soldiers, Shen Long still reluctantly cooked some.

With his guidance, the taste of these foods is much better than the usual big pot rice, and the soldiers have a long aftertaste after tasting it, "This tomato is a little sour, a little sweet...... These potatoes are so glutinous......"

"If you want to say it's delicious, I think sweet potatoes are the best." During this period, the sugar making process had just been brought back from Tianzhu by Wang Xuance for more than 100 years, and sweetness was still a luxury for the people of the Tang Dynasty.

"How many corns should be on this cob?" Someone began to slowly count the grains on the corn cob, calculating how much an acre of land could produce, and although it was not known the density required to grow the corn, it was only a rough estimate, and the soldiers were still stunned.

"The yield of sweet potatoes and potatoes per mu is more than 1,000 catties, and although the yield of corn is less, it is much stronger than wheat! As long as we can plant these lands well, not only do we not have to worry about being hungry, but we can also escort Guo Junwang and Yang Du to the past! Shen Long began to describe the bright future to these soldiers, and in order to convince these soldiers, he deliberately changed the conservative figures.

"One acre of land can produce a thousand catties!" Still, hearing this, the soldiers' eyes widened, they had grown up farming, and they knew the terrible number; Even if it is the best cooked land in Guanzhong, it is good to be able to harvest 300 catties of wheat a year, and Shen Long here directly has a yield of 1,000 catties per mu, which is more than three times the yield per mu in Guanzhong.

Seeing their surprised looks, Shen Long remembered Wang Anshi's father and son, and immediately someone asked, "Shouyu, since these grains can produce so much, why don't we plant all these fields with sweet potatoes and potatoes?" "The desire for food is also engraved in the bones of these people.

"Come on, we may be used to growing wheat, but no one has ever planted sweet potatoes and potatoes, and we have planted all of them in the beginning, and if there is a case, we will be hungry; Second, although these things are good, they are not as easy to store as wheat, and they are easy to rot if they are not eaten quickly after they are planted; So let's grow some wheat first, and when the big guys learn to grow sweet potatoes, potatoes, corn and tomatoes, it's not too late to expand the area! Shen Long explained.

They are not just tuntian in the six cities, and they have to send troops to fight, and it is not okay to bring sweet potatoes and potatoes when leading the troops to go to battle, if they accidentally rot, then there is no need to fight this battle.

According to Shen Long's plan, the center of these lands will be planted with wheat and interplanted with corn, so as to save land fertility while ensuring harvest. Then plant sweet potatoes and potatoes on the edges; In later generations, grapes and fruits in the Western Regions can be said to be very famous, both high yield and delicious, and can also help these soldiers balance nutrition, so this arrangement is very suitable.

When these crops are ripe, you can eat potatoes, sweet potatoes, corn, and a small amount of wheat to preserve most of the wheat. When you need to fight that day, you will grind wheat flour and make naan, which can be stored for a long time without spoiling, which is most suitable for marching and fighting, and then bring some jerky and raisins to supplement fat and glucose, so as to ensure that there will be no problems.

Then, in the future, the soldiers of the Tang Anxi Metropolitan Protectorate and the Beiting Metropolitan Protectorate will carry naan and raisins on their backs to hang and beat those tribes who dare to disobey the orders of the Tang Dynasty!

"It's still thoughtful!" After listening to Shen Long's explanation, everyone was greatly admired, "How should these things be planted, and they have to be caught to teach us!" ”

After convincing these soldiers, Shen Long led them to begin to cultivate the land, and they worked in the fields during the day, and returned to the city at night, holding torches to listen to Shen Long explain to them how to grow these new crops; Despite the fatigue, Shen Long took the lead in leading them to work every day, and he did more than any of them, and these people did not complain.

Everyone is like this, so why should I complain about a small soldier? And when they think of the harvest that is about to come, they don't even have the last bit of slander.

These soldiers were accustomed to farm work, and letting them wait for the crops was more neat than wielding knives and guns, and after working for a while, they finally reclaimed this large area of land, and Shen Long began to lead them to sow seeds.

Based on the existing conditions, relying on historical data and Ivan Vanke's mechanical design capabilities, Shen Long designed some wooden agricultural tools, which were built and distributed to soldiers by craftsmen in the city to help them improve their farming efficiency.

After a short period of adaptation, the soldiers quickly got started, and with the help of some animal power, more than 1,000 people planted tens of thousands of acres of land in a short time.

"Shouchuang, if this is a good harvest, how long should we be able to eat? I'm afraid that even the armies of Xizhou and Qiuzi can be fed! The guide who was lined up by Guo Xin to Juliu City asked.

"When the grain is harvested, we will naturally escort Guo Junwang and Yang Du to the past, and then we will send some people to bring seeds over and teach them how to plant." Although the conditions in Xizhou and Qiuci are not as good as those in the north of the Tianshan Mountains, it is enough to grow potatoes.

"Guard, these farming tools are so useful! Can I let the caravan take it back to Chang'an and let it be used by my family? If I had these, my father and mother wouldn't have to work so hard! The young soldier from Chang'an asked.

"It's easy, but there's no need to send farm tools over, when the caravan comes back, I will give the drawings to the steward of the Guo family, and let them build farm tools for your family!" These things are also very useful in Datang.

After a few more days, it was finally time for these crops to sprout.
