War is fought by strength, defeating the weak with the strong is a high-probability event, and defeating the strong with the weak is a low-probability event; although there are many successful examples of defeating the strong with the weak in history, the conditions for success are quite harsh in all such cases, and if hope is based on chance, it is very unrealistic. ↙ Eighty-eight ↙ ↙ reading ↙, .※.o◇

The war with the Sima family, Cao Liang never expected to achieve the final victory through a battle, this war will be a long-term, protracted war, and arduous, and it must have enough patience, confidence, and perseverance, and there is no place for stealing corners.

The basis of the war is the population, the population represents the soldiers, taxes, the Sima family occupies the vast majority of the territory of the Wei State, controlling more than eighty percent of the population, so the Sima family's war strength is the most abundant.

And Cao Liang only controls one state, and the economy is relatively weak, and the population is relatively sparse, even if Cao Liang forcibly relocates the people of Hanoi to merge, the population of the state is only six or seven hundred thousand, according to the ten to one soldier and civilian configuration, six or seven hundred thousand people, at most can only feed sixty or seventy thousand troops, the number of the current state army has basically reached the upper limit, and if the army is recruited, it is already beyond the range that the people of the state can afford.

Of course, Cao Liang can also solve the army's food and salary problem and reduce the burden of the people through the way of tuntian, but tuntian is also a double-edged sword, it has great benefits in solving the army's grain and grass supply, but the army's excessive participation in agricultural production will inevitably reduce the time for drills, so that the army's combat effectiveness will decline.

What is even more troublesome is that once a large-scale battle is launched, the army of Tuntian must be called back to fight, and the field of Tuntian will inevitably be abandoned. ¥ ♀ Eight ¥ ♀ Eight ¥ ♀ Read ¥ ♀ Book, .2 ≠ ◆

Therefore, in the current situation, it is not impossible to do Tuntian, but it is necessary to control the scale and not affect the army's operations and training, and not to reduce the army's combat effectiveness.

The military and civilians of Tuntian did not come from the active army, but mainly prisoners of war, Hu people, prisoners, and displaced people, and all these redundant personnel were incorporated into the sequence of Tuntian to enrich the foundation of Tuntian.

In the Han and Wei dynasties, the agricultural production efficiency was very low, and the agricultural production of later generations was very different, as an example, the yield per mu in later generations could reach 800 kilograms, and now, I am afraid that even one-twentieth of the later generations could not reach. In this era, an adult labor force can only barely feed a family of three after a year of hard work, which requires God to open his eyes, the wind and rain are smooth, if there is a famine, there is no food to eat, can only eat soil.

In this regard, Cao Liang also said that he was quite helpless, after all, the development of agricultural technology needs to be passed on from generation to generation, especially the selection and breeding of food crops is extremely critical, without Yuan Longping's hybrid rice, it is likely that China's 1.4 billion people will still be hungry.

Cao Liang couldn't change into hybrid rice, corn and potatoes, so he could only honestly go to the tuntian, build water conservancy, expand the area of irrigated land, and change the farming mode of relying on the sky for food.

In terms of farming tools, Cao Liang widely promoted iron farming tools and designed the Quyuan plow.

The ploughing technology of the Han and Wei dynasties has been relatively mature, but the plough of the Han Dynasty is a long straight plow, when ploughing the land, turning back is not flexible enough, the soil is laborious, and the efficiency is relatively low.

The appearance of the Quyuan plough in history was at the end of the Tang Dynasty, the real technical maturity was in the Song Dynasty, Cao Liang once visited the museum is to see the Quyuan plough of the Song Dynasty, the tour guide at that time also proudly introduced that it is the emergence of the Quyuan plough, so that the ancient agriculture from extensive management to intensive farming, greatly improved the efficiency of agricultural production.

Cao Liang was more impressed by the Quyuan plow, so after going back with a little recollection, he drew the drawings of the Quyuan plow, so he summoned a few carpenters and blacksmiths to build the Quyuan plough according to the drawings, and after several improvements, the first sample of the Quyuan plough finally came out.

After trying it in the farmland, all the people were surprised, this kind of curved plough is flexible and easy to use, which can save a lot of manpower and animal power, and the effect of ploughing is directly doubled.

Doubling the efficiency of arable land is terrifying.

If the effect of cultivated land can be doubled, it means that the area of cultivated land can be doubled, and the doubling of cultivated land means that the grain output will be doubled, even if it is subject to other factors, only an increase of five or six percent, that is also a great achievement, in order to solve the problem of lianghuang, to improve the establishment of the army, it has practical significance.

Cao Liang ordered more blacksmiths and carpenters to be recruited, and even temporarily stopped the armory workshop in the barracks, and went all out to build a new type of curved plow.

This has been invented and designed by Cao Liang when he was the governor of the state, three or four years have passed since then, and now at least in the state, the quyuan plow has completely replaced the straight plow, and the agricultural production of the state has increased by at least seventy percent compared with the previous one, and the grain produced has increased by more than fifty percent.

Grain production increased by more than fifty percent, which is already a rather terrible data, today's merger and state, the warehouse is solid, every family has surplus grain, it can be seen that the popularization and use of Quyuan plow, has produced a great effect.

A single Quyuan plow can have such an obvious effect, which undoubtedly makes Cao Liang full of confidence. Solving the problem of rations for the people of Bingzhou will undoubtedly ensure the improvement of the army's establishment, and the left guard battalion of Zhan Hong and Liu Jing's right guard battalion will soon be established, and the Xiaocai battalion will also be expanded from 5,000 to 10,000 people, and the number of Bingzhou troops will surge from 50,000 to 80,000.

This is only the number of mobile legions, not including the county soldiers guarding the counties, if you count all the soldiers and horses guarding the towns in various places, I am afraid that there will be 100,000 people.

Thinking that Shu has a population of one million, but only has 100,000 soldiers, and the state with a population of six or seven hundred thousand, can raise 100,000 soldiers, this number is indeed a bit incredible, plus the state is more mountainous, the climate is arid and rainless, and the agricultural production efficiency is low, it is not easy to achieve such an achievement.

But Cao Liang really did not use military force, but built the army on a reasonable basis, in which the invention and expansion of the Quyuan plough played a decisive role. 11...Friends who read books, you can search for "blue Chinese network", you can find this site as soon as possible.
