Chapter 1397 Great Construction

On the evening of February 15th, the fourteenth year of Tianxuan, after Shi Buhui sent away the 3,000 soldiers of the Firearms Army who were going to build a permanent defensive position outside the city, he hurried back to the restaurant of the Lord's Mansion of Yuexia City. In the restaurant of the City Lord's Mansion in Yuexia City, the newly arrived high-level officers of the Firearms Army and the team of green plant experts from Liandao Green City, the holy land of Yidi's territory, are being entertained.

  In fact, about 500 meters away from the city wall of Yuexia City, there are already eight construction sites that are simultaneously building the second-level city wall. This is the expansion area of ​​Yuexia City.

  The green plant expert team from Green City also learned from the City Lord of Green City that the purpose of Qu Mao and Liu Qianhui's expansion of Yuexia City is to facilitate their research on the native plants around Yuexia City in the city, and they are all deeply moved.

  At the dinner party, the senior military officers of the Firearms Army and the team of green plant experts chatted enthusiastically with each other. Qu Mao and Liu Qianhui were also very willing to see such a scene.

At the banquet, Qu Mao knocked on the table, attracting the attention of Sunan, the city lord of Green City, Shi Buhui, and Liu Qianhui who were eating with him at the table, and said with a smile: "Everyone, for the construction I still have a good understanding of villages, building towns and other affairs. After all, most of the towns and villages in the Holy Land were planned and built by me.

  The words of the lord of the green city this morning reminded me that to change the climate in the desert, especially the practical difficulty of the large temperature difference between day and night, building a large freshwater body is indeed a good choice.

  In the past, I planned so many villages and towns in the holy land. Almost every village or town will dig 1 to 2 water storage ponds, and even dig some drainage ditches to connect different water storage ponds. Including building towns and villages on unvegetated islands such as Lian Island and Sky Island, and I never forget to plan reservoirs or reservoirs.

  After we established the Shaliu Marquis territory, Lord Liu Qianhui was in charge of planning and supervising the completion of the early city building tasks. Although I also came over later, because of the severe water shortage in the desert environment, I also ignored this point. "

  Liu Qianhui rolled her eyes and said, "Qu Mao, don't stand up and talk without back pain, you can dig a reservoir at will in the desert, but the fluidity of sand is much stronger than that of soil.

  Even if you don’t do anything and there is no wind and sand, the reservoir you dug will be filled by the natural flow of sand in a few days. This is the first problem.

  The second problem is: Even if you have an unlimited supply of fresh water, you don't hesitate to fill up the dug cisterns. But the fresh water in the cistern can seep below the sand surface faster than you can fill the cistern, and your cistern won't hold water at all.

The third problem is: even if you saved a reservoir of fresh water with great difficulty, all the fresh water in your pond will be evaporated in minutes after the sun comes out, and after the water vapor enters the air, it will be blown by the wind. Just blowing it to other places far away and then turning it into rain falls, it will not stay in the territory of Shaliuhou Kingdom at all. "

  Green City City Master hurriedly said: "My lord, what Master Liu said has some truth, this is a desert after all.

  The reason why there is no fresh water in the desert is mainly because the groundwater level is too low, and there is no vegetation to resist the direct sunlight, resulting in too fast evaporation.

The subordinates and team members carefully investigated the surrounding environment of Salixhou State and found that the groundwater level is very low. I am afraid that there is no fresh water resource 30 meters below the sand surface. This is also the main reason why it is difficult to grow plants in Salixhou State. , the root system of few plants can penetrate 30 meters below the ground.

  Of course, this is also the biggest challenge we have encountered in improving the desert climate by planting plants in the country of Shaliuhou.

However, a one-day survey in Yuexia City found that the distribution of underground water levels in Yuexia City was uneven, not to mention the surrounding area of ​​Crescent Moon Spring. The groundwater levels in other areas of Yuexia City generally ranged from 5 meters to 10 meters underground. With the prerequisites for planting trees. "

   Qu Mao said dissatisfiedly: "Maybe what you said is reasonable, but the pool of Crescent Moon Spring doesn't seem to have the kind of rapid evaporation that Liu Qianhui said.

  So I'm thinking of taking advantage of the opportunity to expand the city wall of Yuexia City by 500 meters, and build a large number of construction projects in Yuexia City, especially near the northwest direction, to dig at least two large reservoirs out. "

The lord of Green City sighed and said: "My lord, the surrounding area of ​​Crescent Spring is indeed an exception. First of all, the fresh water source of Crescent Spring continuously provides fresh water, and secondly, the root system of that tree must have played a role in conserving the spring water of Crescent Spring. .

  Subordinates should say or not, based on the judgment of the subordinates, if there is no human intervention by the soldiers and civilians stationed in the Yuanyuexia City of the Maoqiusi Kingdom, the subordinates think that there should not be only one tree by the edge of the Crescent Spring..."

  Qu Mao waved his hand to interrupt the words of the city lord of Green City, and said: "Let's talk about our own city building.

As for the problem of filling the reservoir with desert quicksand and seeping water from the reservoir underground, I think we already have cement, and we can completely seal the walls and bottom of the reservoir with cement, so that we will not be afraid of water seepage and leakage. . "

  Liu Qianhui, Shi Buhui, and the city lord of Green City all frowned, Qu Mao glanced at their expressions, and said, "Forget it, there is no need to seal it with cement.

Just like we build a permanent garrison outside the city, we first use cloth bags filled with sand to build them up, and the bottom of the reservoir is also dry. Although water will still seep, the speed of seepage will inevitably be much slower. up the trees, just to water the trees with the water that seeps out.

Well, the thickness and depth of the sandbags must be more than five meters. Now excavate a reservoir with an area of ​​about 10,000 square meters in the northwest corner of the new city wall of Yuexia City. After seeing the effect of the first reservoir , let's look at how to excavate the second cistern and subsequent cisterns.

  I think that with such a small scale, as long as two such large reservoirs are excavated and filled with water, the temperature difference between day and night in Yuexia City can be reduced by at least 10 degrees.

  If this strategy of Yuexia City is effective, I think other towns in the Shaliuhou Kingdom can also adopt this strategy. It is nothing more than that the pressure to supply fresh water from the Holy Land of Emperor Yi’s territory will be greater, and it is estimated that it is only the pressure in the early stage. "

The lord of the green city hurriedly said: "My lord, you should listen to the opinions of your subordinates before making a decision. Based on the calculation of the current 10 hours of sunshine in Yuexia City every day, the subordinates feel that there is no fixed fresh water source. Planting a water reservoir, I am afraid that two meters of water will be evaporated in one day, and if an adult digs a water reservoir with a depth of five meters, it will not be enough to evaporate in three days."

   Qu Mao was stunned for a moment, and asked: "Damn! Then what do you think should be done? You can't just ask questions without mentioning how to solve the problem, right?"

  The lord of Green City was silent for a while, and said: "My lord, I think that the reservoir really needs to be excavated. First, a large reservoir with an area of ​​10,000 square meters and a depth of 6 meters will be excavated in the northwest expansion area of ​​Yuexia City.

But we don't need to fill up with water immediately. According to Master Shi Buhui, you once asked Master Shi Buhui to lead the soldiers to plant bushes with an area of ​​more than one square kilometer there, using the tumbleweeds provided by his subordinates before. And camel thorns.

The subordinates felt that they would take the branches of the big trees by the Crescent Spring and plant them every 10 meters along the edge of the newly excavated reservoir. Penetrate the five-meter-wide sandbags, and see obvious water stains in the reservoir, or wait until the cutting trees survive, and then fill the reservoir with water. The subordinates believe that the probability of success will be much higher. "

Sunan smiled awkwardly, and said, "My lord, the reservoirs and canals in the early days of Yicheng were basically dug out by the subordinates themselves, but there was a stream on the side of the lord's hut in Yicheng at that time, which is the same as the current one under the moon. The situation in the city is different, so the subordinates here can't give any advice.

  But the subordinates feel that the opinion of the city lord is more meaningful. After all, transporting 200,000 tons of water from the holy land of Emperor Yi's territory to Xirong City will consume the capacity of a steam train.

   It will cost more to transport it from Xirong City to Yuexia City. For the Kingdom of Shaliu, fresh water is still relatively precious.

  The subordinates felt that regarding the transformation of the vegetation in the Shaliu Hou Kingdom, the adults should not act too hastily, as the so-called haste makes waste. "

Liu Qianhui pondered for a while, and said, "Qu Mao, I also think that there is no need to go to war for the time being. If you want to build a lot, it is not a big problem, because the desert area does not have much time to work every day, even if there is no sand in the environment of Yuexia City. The original 11 towns in Liuhou Kingdom were so bad, but the available working hours in a day and night would not exceed five hours.

  I think the priority should be given to the protection of troops and residents for the supplies transported by the Holy Land of Emperor Yi’s Territory.

  Currently, the people power of Shaliuhou Kingdom, even if they want to build large-scale construction projects, they still mainly focus on building buildings and city walls. What do you think? "

The lord of the green city continued: "My lord, the 80 green planting experts brought by my subordinates will stay in the lower moon city for a long time, and at least the expanded area of ​​the lower moon city will be turned into an oasis before being transferred to the upper moon city." And Mid-Moon City will continue to plant trees, and the construction of the reservoir will not be a big problem step by step."

   Qu Mao stared, and said: "Green City City Master, when it comes to afforestation and environmental improvement, you are naturally more professional.

  Since you already have a specific idea, and it happens that your team will also stay in Moondown City for a long time, then I will directly entrust you with the task of digging the reservoir.

  Let’s try it in the northwest of the newly expanded area of ​​Yuexia City. It doesn’t necessarily require a very standard square pool. You can try to make the best use of the situation without destroying the existing vegetation.

  After the test, expand the results in other areas of Shaliuhou. In order to support your afforestation plan, I will notify the Holy Land to equip two more steam train locomotives to transport fresh water, plant seedlings and seeds for you and your team. "

  Green City City Master said: "My lord, we still need to use some heroes to carry it from Xirong City to Yuexia City."

  Liu Qianhui said: "I will arrange this!"
