Looking at the endless flow of water, Su Song said: "How much water can this waterwheel produce?" How much can I water in a day and night? ”

Di Dutou said: "Back to the main matter, we have calculated, the water coming out of the waterwheel is three hundred and fifty quintals in one hour, and three acres of land can be watered in twelve hours in a day." If two donkeys are rotated, day and night, five acres of land can be watered in twenty-four hours. ”

The efficiency at night is always lower, so the day and night add up to only five acres. Su Song roughly calculated, a household has thirty acres of land, if there is such a well and a waterwheel, it can be watered in five or six days. As long as it is watered in time, it can withstand drought. Of course, this year's drought is not severe, and not all the fields have to be watered, and it is easier to do so. However, donkeys and mules are not available in every family.

After thinking about it, Su Song asked again: "If you don't use donkeys and mules, and use manpower to push, how much land can be watered in a day?" ”

Di Dutou said: "Even if it is halved, you can only water three or four acres a day and night." ”

Su Song nodded, took a closer look at the structure of the waterwheel, and said to Du Zhongxiao: "It is not difficult to make this waterwheel, if all the villages of the camp and field affairs are built, they will not be afraid of drought." This year's drought is not heavy, so we can build some first, and then slowly make up for it. ”

Du Zhongxiao pointed to the iron chain and said: "It's not difficult to make it, but it uses a lot of iron." ”

Again, the key is iron. In this era, iron is still very scarce, and even iron farming tools are not popular in the countryside, let alone waterwheels that use so much iron. A pound of iron is twenty wen, because the chain is forged, it is made of good iron, and it is more expensive, and the waterwheel is not cheap, and it will cost five or six times just to use iron. With the addition of timber and labor, a waterwheel will cost 20 times, and the cost of household promotion is not low. If you add the matching little donkey, even if it is a field job, it can be difficult to promote for a while.

Seeing that Su Song didn't speak, Du Zhongxiao said: "Now this waterwheel can only be used for emergency use, and it is built in a suitable place, and it is not a matter of time and day to make all the fields watered." We can ask the blacksmith to build some first, choose a village to install it, and pour some good land. When there is a real drought, the good land can be watered, so that it will not run out of food. ”

Su Song nodded, this is a solution. If you want to harvest in a disaster year like a normal year, the cost is too high, as long as the harvest continues, no one will starve to death, and you can carry the famine. At present, the usual algorithm of agriculture is three points of harvest, one share of land rent and tax, one point of self-consumption by those who farm the land, and one point of savings. That is, three years of normal harvest, can carry a natural disaster with no harvest. If this is not done, it means that the taxes are too heavy, the peasants' burdens are heavy, and there will be problems.

This is how the peasants can calculate how much land they can cultivate to survive. For customers, for example, a family of five does not have any land, and it is all rented. The field tax is one-tenth, that is, one stone per mu is collected, and the field tax is one bucket. The rest of the harvest was divided equally with the landlord, and one acre of land could get four buckets for one, and ten acres of land could get four stones. If you plant 50 acres of land and harvest 20 stones, you will have enough to live, and you will not have the ability to resist famine. Therefore, the government's tax service cannot be borne by the customer, otherwise there will be a flight.

The land is distributed equally, and all the households are the main households, and there are no customers. One stone is collected for one acre of land, thirty stones for thirty acres, three stones for taxes, and twenty-seven stones remaining. In addition to enough food for a family of five, there are also savings to withstand the famine. If the water conservancy facilities are well constructed, the harvest per mu can reach not only one stone, but two stones, and it will be a well-off home. This is calculated on dry land, and then counting ten acres of paddy fields, and an extra one or twenty stones, the life is relatively wealthy, and can afford infrastructure construction.

The model villages of these five battalions near Qingtai Town are divided in this way. Other mulberry orchards and orchards are regarded as the welfare of farmers, so that in addition to food and clothing, they can also have money in their hands to support the development of commerce.

The plan is planned like this, and it looks wonderful. However, the slender men really do not know how to farm, and the current reality is not optimistic, not only the crops in the field are not well managed, but even the estimated ten acres of paddy fields, most of the villages are not visible, and the water conservancy facilities are blank.

What can be done? Let them build roads and open canals, and the commanders and capitals in the villages below have changed halfway, and the progress is still not satisfactory. If it is pressed down again, I am afraid that there will be no one to do it for the officials at the grassroots level, and there will be no one to top Du Zhongxiao, so the progress of the project can only slow down.

Manpower is sometimes poor, and Du Zhongxiao has no choice. The manufacture of this kind of waterwheel is one of the remedial measures, through a variety of methods, so that the farmland infrastructure can be improved as soon as possible. If this area is done well, it can be promoted to other places.

Just like this village, Di Dutou is a capable person, and the waterwheel was built in their village, which is very helpful. When digging the well, he found a few strong sweaters and dug the well in one day. However, after the waterwheel was built, there was no idea of quickly popularizing its use, but standing here, as the political achievements of the transport judges, dressed in red and green, specially for people to see.

The seedlings in the field outside had already wilted, and Du Zhongxiao saw it in his eyes, so anxious. If this is my own land, if I get this watering tool, I will definitely dig many wells. The waterwheel can be disassembled and installed, it is nothing more than dismantling and installing here and there, watering the crops in the field as soon as possible to keep the harvest after autumn.

But these slender men who farm the land are not in a hurry, and the crops in the fields have not been seen a few times, and they are chatting in the sun and in the sun, and they are so chic that they can't do it. They are accustomed to the life of receiving money and grain, and when the rice is distributed every day, the crops in the fields are not cared for at all.

Looking at the elated appearance of the surrounding villagers, watching the excitement and being happy, not caring at all about the actual meaning of this waterwheel, Du Zhongxiao could only sigh in his heart. The fields are easy to open, but it will take a long time for these people to become real farmers. If you have to harvest the crops, some people have more families, and some people have fewer families, and you have the heart of comparison, you will start planting the land seriously. After a few years, some families have a prosperous life, build a new house and buy new clothes, and other people's eyes are red, and they know that they need to carefully serve the crops in the field.

Du Zhongxiao can't afford to wait, how many years can he work in the camp? Laying the foundation, I don't know how many times I can reap the fruits.

These days, Du Zhongxiao often goes to the villages below to inspect the fields to see how the land is planted, and the more he looks, the less confident he becomes. The only thing that can be done is to plan as reasonably as possible, put the framework together, and then train people to let them develop slowly.

Repair roads and canals, make water wheels for them, everything is ready, Du Zhongxiao will go to Yecheng. Agriculture has been effective for a long time, and it is not as good as his own farming in Yongcheng back then, so he has to let it go first. When Yongcheng was recruited, all the old farmers who had been farming for many years were recruited, so why bothered so much? In the first year of farming, those people harvested a lot of grain, which earned Du Zhongxiao political achievements. Now the camp and field affairs will be able to feed their stomachs when the grain is harvested in the autumn, and there is no need for other states and counties on Jingxi Road to transfer grain, so thank God.

If you want to make political achievements, you still have to rely on industry, and you have to rely on the iron mines and coal mines in Ye County. The next batch of slender men to come, Du Zhongxiao has already made up his mind not to let them open the field, and they are all arranged to go to Yexian County to open mines and do farm affairs. Slender men have always been militarized, they are used to being managed, maybe the working environment is more adaptable. Assigned to the village tuntian, they were uncomfortable, and Du Zhongxiao was even more uncomfortable.
