The construction of water conservancy can be divided into several directions, one is to dredge the river channel, excavate the irrigation canal, this way is slow to work, and it requires a lot of manpower and material resources, and can only be used in the area near the river, and the restrictions are still very great.

However, the benefits of digging irrigation canals also have their advantages, because irrigation canals have a large irrigation area, and once they are put into use, they can be almost once and for all.

The other is to drill wells for irrigation, which is much smaller in scale, and does not need to be close to rivers or irrigation canals to draw water, only there are aquifers underground, and well water can be pumped anywhere.

However, the disadvantages of drilling wells are also great, because the wellhead is generally very small and deep, and it is purely dependent on manpower to lift water, so the irrigation area is generally very small, if all the irrigation well water is used to irrigate the ground, the number of wells that need to be drilled will be an astonishing number, and the amount of work will be quite amazing.

Julu is located in the Hebei Plain, the waterways are barely counted, the well-known big rivers have Fuyang water, Lishui, Hutuo River, etc., as well as the famous ancient and modern continent, and the rest of the unknown small rivers and ditches are even more innumerable, just take the river water for irrigation, you can irrigate millions of acres of land, but only a hundred acres is obviously far from enough for Wenyuan. After thinking about it for a long time, Wen Yuan decided to grasp it with both hands, and to do a good job in Julu's water conservancy and irrigation system at all costs.

In terms of rivers, Wenyuan is determined to dredge all the original river irrigation canals in Jizhou, as for the excavation of new irrigation canals, due to the amount of work is too large, it cannot be effective in a short period of time, but for Wenyuan to do things never only look at the immediate interests, to do it, you must do your best! From the end of spring ploughing before the Ming Dynasty, we will dig irrigation ditches with all our might, and how many will count!

After the irrigation canal is dredged, the machinery for lifting water is also very necessary, and the invention of Bi Lan in the late Han Dynasty has invented a rollover car, which is a very convenient tool for lifting water, but it is a pity that it is only five years away from now, and it has not yet been promoted, and Wenyuan does not know how to make it at all.

However, although Wen Yuan didn't know the principle of overturning, he had seen another water lifting tool in his previous life.

In the park of his hometown in his previous life, there was a big waterwheel in Lanzhou with a height of seven or eight meters in front of the main entrance, Wen Yuan often saw it every time he went to the park, although Wen Yuan was not from a professional class, but Wen Yuan could probably remember the structure, so he planned to wait until the meeting, so he drew a sketch for the craftsmen to try to do and see.

In addition to irrigation canals, the work of digging wells is also very important, in the drought season, the role of river pools and canals will be reduced accordingly, the people of the Han Dynasty have long had the habit of digging wells in the fields for watering people and animals, but it takes a lot of money to dig wells, generally more than ten meters deep wells will cost two or three thousand dollars, thirty or forty meters deep is even more need seven or eight thousand, such a large expenditure, many poor people simply can not afford it.

However, if there is a drought, the kind of small wells of two or three thousand dollars will either dry up, or the amount of water will become less and less, and digging it is equivalent to digging it in vain, and only the kind of wells that are thirty or forty meters deep or even deeper can draw water as usual in times of drought.

Although this kind of deep well is quite expensive and expensive, each well can irrigate twenty or thirty acres of fields, and it is still very cost-effective to use it for a long time.

According to the existing scale of mud water craftsmen in Julu, Wenyuan plans to dig a total of 3,000 wells in the early stage after the beginning of spring, and initially solve some cultivated land that is far away from the water source and cannot be irrigated with river water.

3,000 wells, converted into more than 20 million yuan, is almost double the annual tax income of Julu! Such a large expenditure, naturally can not only rely on their own funds, Julu two years of bumper harvest, whether it is military households and civilian households, have saved a lot of money and grain, the two share together, the government to work and materials, the people to pay for food, in this way, the expenditure can save a lot.

If these ideas can be realized, Wen Yuan believes that even if there is a big drought in the coming year, Julu County will not lose much grain!

In addition to water conservancy, the establishment of a medical school has been reported, and the foundation of the new medical school has been laid on the banks of the mainland, and it is believed that it will be put into use in more than half a year.

The name of the medical school, Wen Yuan has not yet thought of it, but Hua Tuo must be the principal of the college, and there are also the original medical craftsmen in Julu City, in terms of apprentices, Wen Yuan has already planned to draw a part from the military households first, and will also select a group from some poor families to study with Hua Tuo, all apprentices who study medicine with Hua Tuo will be paid monthly by the government, and this matter does not need to wait for the completion of the medical school to be done, Wen Yuan plans to start recruiting apprentices now, so that the apprentices can learn to become teachers as soon as possible, It was then assigned to the medical workshops to be established in each county and village in the future.

According to Wenyuan's plan, the lowest-level medical workshop should be popularized to every county, county, and village under his rule, forming a complete medical system network covering the entire Julu and even the party from top to bottom, so that the people can get medical treatment, which is also the goal that Wenyuan has set for himself.

After listening to the political affairs reported by the frustrated professor, it was followed by a report on the military aspect.

For the Julu Army, which has a population of only more than 400,000, 40,000 troops is already the limit that Julu can bear, so in the past few months, Zhang Jaw has not recruited strong soldiers, except for stepping up the training of the main and auxiliary soldiers, there are not many things, and Zhang Jaw has also put the focus of his work on improving the equipment of the soldiers.

In the past four months, the Julu craftsmen have created nearly 1,000 pairs of wrought iron armor and thousands of hard crossbows, in addition, the blacksmith workshop has also recently created 500 Mo knives, which have also been sent to the gall pottery warehouse, and there are also a lot of other kinds of ordnance baggage.

Wen Yuan nodded lightly after listening, Wen Yan praised it, and didn't say anything.

In the evening, Wen Yuan returned to the mansion, and according to his orders, Wang Li waited in his study early in the morning.

Wen Yuan sat lazily on the bed, in front of Wang Li, he didn't need to be too serious, but Wang Li always bowed his head and stood beside Wen Yuan, waiting for the lord's inquiry all the time.

"Wang Li." Wen Yuan rubbed his temples, trying to clear his confused mind, he used to drink the low-alcohol wine of the Han Dynasty and developed the habit of using a big bowl, but now he is drinking high-grade wine made by himself, and Wen Yuan has been drunk several times.

"The little ones are here!" Wang Li responded and took a cup of tea from the case and handed it to Wen Yuan.

Wen Yuan took a sip of water, sighed and said, "In the past few days, there is any new information. ”

Wang Lili took out a few notes from his sleeve and handed them to Wen Yuan.
