The principle of the pumping machine for the well canal is the same as that of the pump, but compared with the old-fashioned pump, although the tools prepared by Zhang De for Ma Zhou are not as good as the "Friends of the Miners", they are better in terms of popularity, and they are easy to maintain and maintain.

With the use of fig pin and eucommia gum, the iron pumping machine can make the pipe diameter larger, thick and long, and the effect is very good.

In addition to the drought-resistant requirements of the wells and canals and the Hetao and Hedong areas, Zhang De is not without other considerations, such as the Yunmengze area, where the enclosing of polders and cultivating fields is a process. When pocket-sized lakes are dried up, large wetlands are formed, and wetland development is another process.

In order to ensure the good operation of Datang No. 1 construction site in the future, the primary guarantee is still food, and stable output is the condition for continuing to expand reproduction.

Although the farming system of Middle-earth matured very early, the operation of the empire also had a strong inertia. For example, agricultural activities did not rely on the consciousness and knowledge of yeoman farmers, but on the guidance of the agricultural bureaucracy under the imperial system. This is also the reason why "persuading the peasants" is a key point of attendance for bureaucrats.

If farmers only rely on experience, they can only find a way to optimize breeding on staple foods. However, food is not abundant, and at the same time, the model of increasing yield per mu of underground production by extensive cultivation makes it impossible for farmers to boldly try other grains as staple foods, and of course, technology is also a chasm.

For Lao Zhang, an engineering dog, in the era when things like spicy strips can be sold 1,500 years later, the food industry is the strong backing for this kind of play.

And "Qi Min's Technique" is a bold attempt of the Northern and Southern Dynasties miniature version, Jia Siqian is a system member after all, and his status in the rivers and lakes is three streets stronger than that of mud legs.

The pumping equipment is used in the lowlands and wetlands of Yunmengze, and in addition to rice, there are also starchy high-yield crops, one of which is the mushroom.

"Qingming Xintian, how much more planting?"

Li Fengjie took the field book for February and asked the newly appointed head of the grain shop in Chuzhou.

"20,000 acres, mountains and rivers."

"Did the local farmers say anything?"

"The officials of the governor's palace have come to see it, and the natives have not spoken a word. Occasionally, it is also some ridicule. ”

"Hmm."

Closing the field book, Li Fengjie said again: "Where is the germination of new seeds?" ”

"Hanyang is Yangzhou and Jiangxia is Suzhou."

"Remember to enter it in the book."

"Lang Jun rest assured, the little one is awake."

After saying goodbye, Li Fengjie rode a horse to the west of the city, and on the way he saw a few of An Bo's partners, took two taels of China Resources Jinyuan, and asked them to recruit another group of Anguo fellow villagers who had no way out.

When he arrived at the men's mansion in Liangfeng County, Li Fengjie told Zhang De about the Xindi in Chuzhou, Zhang De poured him a cup of tea, nodded and said: "I won't tell you, the new flour is filled with glass jars, and after being sealed, it will not be a problem to store it for more than a year." ”

In the past, wheat had no eggs, and even the poor and exquisite old masters hated wheat rice, let alone nobles. Unless there is a special reason, wheat rice will not be a noble meal at all. Like Li Dong, who eats a bowl of carved rice and sheds two tears with emotion, is the serious ruling class.

However, nowadays, wheat is in short supply, and the steamed buns, cakes, and breads made of flour are all based on flour grinding technology. Even noodle lovers who often eat cold tao now understand that alkaline artemisia seeds are of great use.

"Brother means ......"

"What is the yield per mu of mushroom Yangzhou?"

"Two thousand pounds."

"Hanyang is much better than Yangzhou." Zhang De took a sip of tea, "Jia Junpeng harvested Hebei mushrooms the year before last, and there were 1,500 catties per mu. For my brother in Cangzhou trial production of some mushroom powder, one acre of land can produce 100 catties to 200 catties. ”

"Can mushrooms still produce powder?"

"Yes, but it's not as good as taro."

The taro powder is extremely high, and the broken place in Hedong can yield more than 2,500 catties per mu. This matter was not pondered by him, but experimented by Jia Fei based on the exposition of his ancestors.

Jia Siqian is not a genius, he is a super genius.

According to Jia Sixian's theory, in order to prevent a famine, as long as one or two acres of a family's 30 acres of land are planted with taro, they can ensure that they will not starve to death.

However, the broad masses of the people can't say it, and Jia Siqian can't say it either, although he is in the system.

The fly in the ointment is that Jia Siqian can't make taro flour, especially taro flour that can be stored.

After a rough calculation, the minimum flour of taro per acre is 300 catties. This grade is comparable to the gross income of the rice in the field. Some go to the field, and the yield of millet per mu is only more than 100 catties, which can only be maintained by extensive planting. And as long as you master the right technology, it's okay to starve people to death.

It's a pity that the peasants don't understand how to plant and when to plant at all, and most of the agricultural experts are the staff or adjutant of the local chief, and the most important are also officials.

Farming techniques have always been official.

"Brother, on both sides of the Han River, there are many no-man's lands, if you take it, you can make a profit without losing money." Li Fengjie calculated an account in his heart, according to this market, if he just grows mushrooms to eat, he can actually live people. But this is not enough, because it is less difficult to grow mushrooms than rice.

The biggest difficulty is that there is no harvest of mushrooms, and it is unstable. The awesome thing about rice is that its output per unit time is very stable, and it can be planted one after another, and Hanyang can be planted for at least two crops.

Moreover, the troublesome part of the mushroom is that it is not sown on dry land, but needs to be used as base fertilizer in wetland paddy fields. According to the tradition of Yangzhou people, after the fermentation of human and animal manure, a layer of fertilizer is supplemented, and then river mud is used, and finally ploughed, and then the budding mushrooms are selected for planting.

Zhang De asked people to enclose the polder in the enclosure of the polder in Chuzhou, which took into account the reason for the river mud to be fertilized. After the pond is cleared, it is also possible to trap fry to raise fish.

There are many things involved in this, not to mention the project of encircling the polder, just turning the ground, you have to remake the Quyuan plow, which should be suitable for the Quyuan plough of the mushroom paddy field, and the plow should be added with a slide on both sides to reduce the pressure, so that people can easily adjust, so that the cattle will not go forward and people can not keep up.

Then there is the collection of human and animal manure, which needs to be managed in a unified manner. Coupled with the drainage irrigation canals and pumping machines used for field drainage, the whole process must mobilize at least 30% of the strength under the China Resources system.

Of course, all this Dou clan is worthy, and it can obtain a large amount of flour, which is enough to make any party swell into a giant in an instant, causing unnecessary suspicion from the central government.

Therefore, to produce such a result, Zhang De has to consider another problem, how many people have to be brought in for this matter.

Just a Li Chengqian, that is tantamount to self-defeating, getting the captain to be late and Cheng Caodi, and it is not too fashionable to beat the dog. As for Fang Mou Dudu, the land of the two families in the Henan circle of Shandong can bypass Chang'an City by 10,000 circles......

But all this must be done, not about the struggle between the emperor and the crown prince, but about the future of the engineering dog carrying a kitchen knife without fear of the emperor or the duke grinning at him.

Shicheng Iron and Steel Plant is one arm, the largest construction site in the country, it must be another arm, and both arms have to firmly grasp two stainless steel kitchen knives, so that the waste that will be used as a prison can only watch the magic weapon being cut into garbage.

When the engineering dog was thinking about becoming bigger and stronger, a certain Hill Muye man wiped his mouth in the cafeteria, and then said to his fellow villagers with a smile: "How about it, the fat intestines are delicious!" ”

"Mmmmmmmmmm......mm

The villagers of Shir Muye, who came to the Tang Dynasty with the Persians, were full of emotion: Is there a more beautiful animal in this world than pigs?

"So, what are you thinking?"

Shaheen rubbed his hands together, his eyes incomparably bright, looking at his fellow countrymen. (To be continued.) )
