In the spring of 72 B.C., the ice floes in the Peacock River had not yet melted, and the Yellow Banner of Ren Hong, the capital of Anxi, left Luntai, where the capital was stationed, and came to the city of Quli, where he had fought.The canal plough has left a legend about the Marquis of Xi'an everywhere, what iron gate closed overnight, covering the valley fire ox to break the enemy, and with the return of Wu Zongnian to the Han Dynasty, the Tibetan head book that was not suitable for propaganda in the past separated the right kings, also circulated in the war.Not to mention the seven battles and seven victories in the last war, which made General Anxi a legend more revered than the Marquis of Yiyang.Although Lao Sun regrettably missed the opportunity to change his name in Chigu Castle, he was also promoted to the rank of Guandu Lieutenant, with a rank of 1,000 stones, guarding the iron gate, and being responsible for the matter of ditch ploughing and tuntian.The ditch plough was only the starting point of the routine inspection of the new official after he took office, and he only joked with the left and right; "The inner county guards the county every spring, but I am patrolling the country!"
After the name was changed, Anxi Dadu Protector, Zhilu was mentioned by Huo Guang as Taishoutong, but his power was much greater, not only in charge of a few captains and thousands of soldiers, and in the custody of thirty-six countries, but also in essence to declare war and diplomatic power, of course, if the internal small state died, it could only be regarded as "counterinsurgency".The first thing Ren Duhu did after arriving at the canal plough was to ask Sun Wan to take him to see the tuntian by the Peacock River.Quli City is located on the bank of the Peacock River, the mother river of the Loulan people, and the benevolent river god worshipped for generations is a rare non-tributary water system.Its only source comes from Bosten Lake, where water overflows from the western part of the lake, passes through the Tiemenguan Gorge, flows through the canal plow, and then flows southeast through the Gobi for hundreds of miles to flow into Lop Nur.In the event of a severe drought in the Yanqi Basin, the water level of Bosten Lake will be lowered, and the Peacock River will be cut off in minutes, which will be a catastrophe for the people of Loulan.But at least in the canal plough, the Peacock River is still very abundant, occasionally even flooding, compared with a few years ago, the number of tuntian has increased greatly, but the agricultural official in charge of this tuntian is particularly not satisfied, Ren Hong just took office, he picked up Sun million, put forward a grand plan, which made Ren Hong very concerned, must come to inquire in person.Song Litian, the agricultural official of the canal plough, was a rickety black and thin old peasant, darker than Fan Shengzhi, and he did not wear a scarf, but wore a flat bun, a wooden hairpin, a few white threads in his black hair, always wearing a short beat, a sickle on his waist, and his legs were held high, but there was not much hair on his legs.Everyone he saw had a stinky face, and Ren Hong also smiled and bowed his hand: "Song Litian, I haven't seen you for many years." ”At that time, Ren Hong was sent by Fu Jiezi to be Sima in the mud city, and helped the king of Shanshan to plant a small land for half a year, and it was Song Litian who helped him promote farming and the method of replacing the field in the mud, and now he is put into the canal plow to exert the residual heat."
The old man doesn't dare to accept the heavy gifts of the capital."
Although Song Litian had a relationship with Ren Hong, he was too lazy to climb any relatives, only pointed to the fertile fields on the banks of the Peacock River, and simply introduced the Tuntian plan drawn up by him and Sun Wan."
Don't hide it from the capital, the old man followed Zhao Sosu in Hexi in his early years to promote the field method, and got the order of Dasi Nong, that is, Sang Gonghong Yang, to plow the ditch and inspect the soil and identify the soil."
At that time, it was the late years of Emperor Wu of the Han Dynasty, and after learning the lesson of Li Guangli's two expeditions and lack of food, he decided to expand the tuntian in Luntai, Quli and other places to recruit people to live on the border.Sang Hongyang's performance was done according to Song Litian's proposal, although Sang Hongyang has been completely defeated, but Song Litian's words still have respect for his old boss.Sang Gong said, the canal plough water and grass are abundant, the land is fertile, suitable for planting grains, can be more than 5,000 hectares of tuntian here, a year to support 500,000 stones!
This was determined by the old decay and many agricultural officials. ”Then there was an edict of Luntai, and the matter was not resolved until Xiaozhao re-operated the Western Regions, and the Han army returned here, and after blocking the Xiongnu outside in the Battle of Tiemen, Tuntian gradually recovered.Ren Hong bowed his head and asked, "How much land has been opened by the canal plough now?"
”Sun Wandao said: "Now there are more than 500 hectares, and more than 50,000 stones of corn and wheat are obtained every year, which is enough for thousands of people to eat. ”"But Song Litian thinks that the cultivated land can be expanded several times or even tenfold."
Song Litian immediately said: "The premise is that we can build embankments, build ponds, open ditches, and divert water from the Peacock River to irrigate crops!"
”This is the plan of Song Litian and Sun Qian, he hopes to turn the canal plough into the granary of the Western Regions as planned by Sang Hongyang, so that more Han immigrants can be fed, and the army can also eat enough when it crosses, and there will be no more tragedies of Li Guangli's two western expeditions, and there will be more tragedy of starvation than war death.Ren Hong was not in a hurry, and first carefully asked Song Litian how he planned to build water conservancy.Song Litian was confident: "The Fangkou weir of the Xueqin River, felled wood and earth and stone piled up into a weir to raise the water level of the Peacock River, and then diverted the river water into the depression as a pond, and then led the water from the pond to the canal to irrigate farmland. ”This is what is often done in the Central Plains and the south, Sun Shuao repaired Shaobi in Huainan, and Ximen Leopard repaired the twelve dikes and ditches in Yehe are all like this.The water conservancy projects of Dahan are even more vast and ordinary, and Guanzhong is full of ditches.It can not only dredge the flood, but also irrigate the fertile land, so as to enrich the country, and the rich people are happy."
Although it will take tens of thousands of laborers, if it can be repaired, 5,000 hectares of fertile land will be enough to feed 30,000 or 40,000 people in the canal!
The subordinates dared to ask for permission from the capital guard, and the Luntai soldiers and Loulan, Yu Li, and Yanqi Ding Zhuang came to come, and it could be done in half a year!
”"At that point, the canal plough will not be what it is today."
Song Litian said longingly: "Lituntian is in the field of anointing, the mail is placed in the critical place, the Chi Festival is endless, and the merchants and traders are under the plug. ”The more Song Litian and Sun Wan talked, the happier they became, but Ren Hong became more and more worried when they heard it.After learning more about the plan of the two, it was indeed the direction he was most worried about, but Ren Duhu, who had always liked farming, shook his head and resolutely rejected this strategy."
No, this move is used in the Western Regions, just like drinking a donkey to quench your thirst!"
Ren Hong spent a whole afternoon telling Sun Wan and Song Litian what sustainable development is."
This Peacock River is a lone water, which starts at the iron gate and flows into Lop Nur in the Prison Sea.The Western Regions are dry and the amount of water is limited, if the upstream canal plough is dammed and intercepted for irrigation of fertile land, then the water flowing to the downstream Loulan City will be greatly reduced, and the canal plough will increase the land, how much less land will Loulan have, and what is the benefit of the entire Duhufu?
If there is no Loulan, even if the canal plough can accumulate millions of corn, the gain will outweigh the loss. ”If the water of the Peacock River is blocked by the dam, too many trees are cut down on the banks, and soil erosion increases, I am afraid that the flow will be cut off, the fragile Lop Nur will gradually dry up, and the downstream Loulan City will be depleted of water, and it will eventually be abandoned and submerged in yellow sand.Song Litian and Sun Wan looked at each other, and Lao Sun felt that Ren Hong was thinking too seriously, but he didn't know that this was a real thing that happened in history.Population growth, overexploitation, destruction of vegetation, drought and water scarcity and the expansion of desertification are the reasons for the rapid disappearance of the ancient oasis city.Loulan, this mysterious city-state will disappear in more than 400 years, and Lop Nur will be completely transformed into a sea of death after 2,000 years.The diversion of the Peacock River is a sharp sword hanging over the heads of Loulan and Lop Nur, and Ren Hong is still thinking about how to stop this, how can he speed up the process?
He straightened his face and said: "Song Litian, the Han Dynasty opened a canal in Tuntian by the Shule River in Jiuquan County, which has made Dunhuang even drier, and some lakes have gradually dried up. ”Therefore, Ren Hong will not only not allow the canal plough to repair the dam and open the canal, but will tie their hands and feet, and ask the canal plow, like other cities along the Peacock River, to strictly follow the four seasons and months that Ren Hong copied in the hanging spring: prohibit logging, prohibit the killing of young animals, prohibit the shooting of birds, prohibit large-scale construction, and prohibit the burning of mountains and forests in summer, this is the "environmental protection law" of the Great Han Dynasty, whether the Central Plains and the south should be how it is debatable, but Dunhuang and the Western Regions are in need of this heavy code.The standard set by Ren Hong for the canal plough can be extended to the north and south and 36 states, and it is often not natural disasters that destroy the oasis, but the death of human greed.More than 20 years ago, he described the strategy of the canal plough and Tuntian, I thought that the imperial court could re-implement it, but I never thought that it was completely denied by Ren Hong, Song Litian was a little annoyed, squatting on the edge of the ridge and a little angry, and said: "The canal plough will only be able to feed three or four thousand people forever. ”Ren Hong can't help it, the Western Regions is so cruel, otherwise why is the population of Southern Xinjiang still so sparse in later generations?
And the district field method tailored for the Kanto region of the Han Dynasty cannot be used in the Western Regions, do you expect the canal ploughman to be as diligent as the farmers in the Central Plains?
It is impossible for the soldiers and farmers to devote all their energy to the fields, and it is difficult to maintain intensive cultivation due to the lack of manpower.Therefore, the medicine that Ren Hong prescribed for the canal plough was to divert the population.Ren Hong told Sun Wan: "The ditch plough must count the land and household registration every year, and the fields that can be cultivated are set at 1,000 hectares, and the mouth is 5,000 people. ”The south of the Tianshan Mountains was dry and barren, but the population of the oases was constantly growing, and after the Han Dynasty brought peace to the Western Regions, even the best way to eliminate the population: war, could not be fought.The north of the Tianshan Mountains is rich in resources, and the immigrants from the Central Plains are too far away, and few people are willing to come, but they can send some overflowing population from the oasis city-states.In the past, the states were independent of each other, and the Xiongnu only extorted grain and slaves, and did not interfere in their internal affairs.However, after the Han Dynasty entered this place, the 36 states were brought under the jurisdiction of the Metropolitan Protectorate, which was like forming them into a federation and unifying them under the Han Dynasty, and the military and diplomatic affairs were all under the management of the Metropolitan Protectorate.On weekdays, the household registration is counted and the winning soldiers are made and handed in, and in the event of war, the conscription is subject to the dispatch of the capital guard, and if one side is in trouble, the capital guard will bring support from all sides.It is forbidden to deal with foreign countries such as the Xiongnu and Kangju without permission, these things were laid by Fu Jiezi when he was in office, but it saved Ren Hong a lot of trouble.Therefore, in terms of sustainable development, Ren Hong is determined to make the whole Western Regions a game of chess, whether it is the Han Army's Tuntian Point or the Oasis Small State, no one wants to be the black sheep!
After disposing of the canal plow, the soapy yellow flag set off again, along the Peacock River, the only life belt in the Gobi Desert, to the south, intending to go to Loulan, which was the starting point of Ren Hong's steady progress, and also the first political achievement he handed over to the imperial court after becoming the protector of the capital."
Loulan is the first city-state in the Western Regions, the big county is the order, the rank is 600 stones, the small county is the long, the rank is 400 stones, and there are barbarians who say the way."
Ren Hong smiled: "Let's go and see how that zodiac chief has done in the past few months!"
