"The continuous development of productive forces has made the yield per mu of agriculture continue to increase, and the output of China's agricultural planting is also increasing, due to the widespread use of iron farming tools, the development of water conservancy and irrigation and the progress of agricultural technology, especially the improvement of farmers' enthusiasm for production, the output per unit area has increased. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 According to Li Kui's estimate of the agricultural output of Wei in the early years of the Warring States Period, one mu of land can produce one and a half stones of millet in an ordinary year, and nine buckets per mu today. According to the "Historical Records and River Canal Book", all the land irrigated by the water of the Zhengguo Canal can be harvested for one minute per mu. One bell is six stones and four buckets, and the yield per mu is three stones, eight buckets and four liters. In the Han Dynasty, the yield per mu was three stone millet, which was recognized by the Han Dynasty literature...."--Excerpt from "China Agricultural Development Report"

According to the grain planting documents of the past dynasties, later historians have probably derived the grain output of one mu of land in China in the past dynasties.

In the early Warring States period, the yield per mu was 205.8 catties, in the late Warring States period, the yield per mu was 247 catties, the yield per mu was 232 catties, the yield of millet per mu in the Han Dynasty was 281 catties, the yield per mu of beans was 264 catties, the yield per mu of the Wei, Jin, Southern and Northern Dynasties maintained the level of 3 stones per mu, the yield per mu in the Tang Dynasty was 334 catties, the yield per mu in the Song Dynasty was 309 catties, the yield per mu in the Yuan Dynasty was 338 catties, the yield per mu in the Ming Dynasty was 346 catties, and the yield per mu in the Qing Dynasty was 367 catties.

All the above yields are calculated as an average of all grains and are annual yields per mu.

In Cangzhou, wheat is planted for two seasons, Chen Benshun receives about 300 catties in one season, and the income of one mu a year is about 600 catties.

Even Chen Benshun himself once thought that it was impossible to grow more than 600 catties of grain in one acre of land, unless it was black soil.

But as the high-yielding crops grew day by day, he slowly began to feel that what he once thought was a joke.

Jiang Yin was very interested in agricultural planting in the four prefectures and counties, and during this time he kept driving around the four surrounding prefectures and counties to visit the people, on the one hand, to popularize some basic agricultural knowledge that should be known for planting high-yield crops, and on the other hand, to ask them what they thought of local officials and their evaluation of some government systems.

Jiang Yingui is the emperor of the new Song Dynasty, but his style of acting is very different from the emperors of previous dynasties, throughout the ages, as long as he is an emperor, it is by no means easy for ordinary people to see, even if he goes to the countryside to visit, it is also a pre-selected people, selected officials, selected places and times, so that someone can have the honor to see the true dragon emperor.

However, Jiang Yin was not ordered by the sky at all, overriding the consciousness of sentient beings, he sat in a jeep all day long, with two cars of bodyguards, and then randomly went to the countryside to visit, the more poor and decaying places, the more he went.

These also let him see a lot of the dark places of the New Song Dynasty, through the visit, Shun Teng caught a lot of corrupt officials, as well as a variety of local protective systems, for these people and systems that violate the Constitution of the New Song Dynasty, Jiang Yin did not have the slightest merciless intentions, as long as there are corrupt officials, all will be dismissed and investigated, and can never enter the officialdom of the New Song Dynasty again, once the local hegemonic system is discovered, then the local hegemonic landlords or magnates will be escorted into the Honglu Temple, Pending the outcome of the trial before the Central Court.

During this period of time when high-yield crops were being promoted, Jiang Yin dismissed 14 corrupt officials and swept away three land tyrants who were famous for one side, and Jiang Yin's title of Mingjun suddenly spread in the New Song Dynasty.

The social atmosphere of the entire New Song Kingdom was also invigorated.

Originally, there were still many New Song Dynasty officials who were ready to enjoy the tribute of local magnates, but when Jiang Yin's attitude was so resolute, he also quietly retracted the hand he wanted to stretch out.

By constantly tightening discipline, suppressing corruption, and pacifying local hegemony, the new Song Dynasty's originally slightly biased course for peace and enjoyment returned to normal.

Under this good social climate, high-yielding crops in four states and counties are also growing smoothly.

In less than three months of cultivating high-yield crops, with Cangzhou as the center, southward expansion to Qingzhou, Dezhou, Dizhou, four straight asphalt roads are also being built simultaneously, three months later, these three asphalt roads about 100 kilometers long are finally repaired, since then, the new Song Dynasty is considered to have a complete appearance of a country.

Cangzhou was designated by Jiang Yin as the capital of the new Song Dynasty, with Cangzhou as the center, three wide asphalt roads led to Qingzhou, Dezhou, and Dizhou respectively, and these three asphalt roads were designated by Jiang Yin as No. 1, No. 2, and No. 3 national highways, and in the other three states, there was only a township road connecting these three states and counties.

With a wide and straight road, both pedestrians and horse-drawn carriages can pass quickly on the road, Jiang Yin's next plan is to use the township roads in all the sixteen townships and counties below the four states to repair the roads.

Although the amount of work is huge, in the face of modern mechanized equipment, these are just problems, and it only takes some time for these roads to be completed.

While Jiang Yin was building the country in a big way, in three months, the high-yield crops were basically ripe.

Cangzhou is located in the plain shallow mountainous area, is a treasure land for growing grain, if you plant autumn corn in this terrain, you can even grow three times a year, although sweet potatoes can only be ripe once a year, but the growth of sweet potatoes is faster, no need to wait until it is fully ripe to receive, and the yield will not lack too much.

Therefore, at the end of June, Jiang Yin announced that the whole country would begin to harvest grain, and the land that was originally planted with sweet potatoes would be planted with another round of corn to reach the standard of double corn cropping.

The harvest began, and after three months of hard work, the fruits were to be harvested for the first time, and the people of the New Song Kingdom who planted those high-yield crops were all excited and apprehensive.

However, the high-yielding and high-yield varieties brought by Jiang Yin from modern times did not disappoint them, the sweet potatoes with thick arms of adult men were dug out of the ground one by one, and the corn that was growing happily was broken off from the corn stalks one by one by crazy farmers, and the whole New Song Dynasty was full of excitement and joy of a bumper harvest.

Chen Benshun went to the field as soon as he received the grain, and when he took his assistant to pick all the fruits that could be picked in the field, his excited snot and tears flowed out together.

Needless to say, just by virtue of the yield through his own hands during the harvest, Chen Benshun felt that it had exceeded 1,000 catties.

In fact, not only more than 1,000 catties, but also far more than the entry-level threshold of 1,000 catties, the weight of the sweet potatoes and corn received, together reached a terrifying 3,000 catties per acre.

Three thousand pounds! That's 3,000 pounds!

Chen Benshun swore that he had never seen anything that could grow 3,000 catties from an acre of land in his life, and he didn't even dare to think about it, but when he cried with joy and told those overseas gentlemen the news, those people showed disappointed expressions.

"The use of chemical fertilizer is only 3,000 catties, I said that the effect of pesticides is still too important, we don't use pesticides, at least 2,000 catties have been lost."

"Yes, yes, if we increase the sodium content of nutrients a little bit, and have a little insect repellent effect, we can increase the yield by at least 500 catties."

"This is only the first year this year, the land is rich in fertility and only 3,000 catties of chemical fertilizer are used, and it is estimated that ordinary people can only reach 2,000 catties in their homes....."

.... Listening to those overseas gentlemen discussing the arguments of 2,000 catties and 3,000 catties, Chen Benshun had a deep feeling at this time, as if he and they were not living in the same world......
