After the speech, Hao didn't stay in Lionroar City for long, and the next day he said goodbye to Owen and returned to the Savage Land with the accompanying subhuman patriarch and escort to prepare for the relocation and other matters.Obviously, he's going to be very busy.Two weeks later, the Ghost Race's right-hand man, Wu Ming, led a group of sub-humans of different races to the junction of the Savage Land and the Canaan Desert.In addition, they brought more than a dozen truckloads of dried wheat straw, as well as all kinds of necessary tools and supplies.Most of these things are provided by the human side."
Assemble, please!
I'd like to explain to you what exactly is needed to control the desertification here. ”A lizardman (green lizard) who knew human writing held a booklet with the "Desertification Control Plan" printed on it, and shouted loudly at the subhuman race present.This "Desertification Control Plan" was previously compiled and printed by Owen Alpha to retrieve the scientific desertification control materials accumulated by a great country in the past of the Earth Alliance."
Hurry up, assemble!"
Wu Ming, who was appointed as the captain, also urged: "Line up here, hurry!"
”Hearing this, the people put down the handles of the wooden carts one after another, gathered in the open space in front of the lizardman, and stood in line.After counting the number of people, Wuming turned his head to the lizardman on the side and said, "All the personnel are here, and you can explain and arrange today's tasks." ”"Please listen carefully, and if you don't understand, you can wait until I finish talking before asking questions."
Flipping through the "Sand Control Plan" in his hand, the lizardman began to introduce the above sand control methods to everyone."
What our team has to do is the grass grid sand fixation method, the specific steps are as follows......
"Grass grid is an effective sand control method that can prevent wind and fix sand and conserve water, and its production can be divided into three steps - the first step is to grab a handful of dry wheat straw and beat it with the wind, and shoot off the inferior wheat grass that is relatively broken, leaving only the good quality long wheat grass."
Subhumans who don't have scales or exoskeletons on their hands can do this job with gloves, after all, it is dried wheat grass, and if you grasp it directly in your hand, you may accidentally puncture the skin.In the second step, the processed dry wheat straw is neatly stacked on the edge of the square drawn in advance on the sand, and the middle part of the dry wheat straw should be aligned with the edge line, and the size is 1×1 meters.When stacking, pay attention to keeping the thickness of the dry wheat straw moderate, neither too thick nor too thin.If it is too thick, the dry wheat straw will easily fall down under the action of its own gravity, and it will not be easy to stand.If it is too thin, the grass grid will not be strong enough to prevent the Canaan Desert from continuing to erode northward.The third step is to take a tool shovel and press hard along the edge of the square, insert the middle of the dry wheat straw into the sand, and the ends will stand up to form a natural barrier, and the height can be maintained at a height of 10 to 20 centimeters.After stepping on it, the sand on both sides of the dry wheat straw should be pushed towards the roots to make it firmly fixed on the sand.In addition to the good effect of wind prevention and sand fixation, the grass grid also has a strong water conservation function, and the effect of controlling snow in winter is as high as 100%.Putting up a good grass grid does not mean that the work of sand control is over, sand control is a long and large project, and in the future, plants can be planted in the grid to further strengthen the ability to prevent wind and fix sand.In addition, dry wheat straw is, after all, a dry dead thing, which will be eroded and rotted by the wind after four to five years of rooting, and will need to be re-tied at that time.“…… The above is the process of making a grass checkered sand barrier. ”Closing the "Sand Control Plan" in his hand, the lizardman looked up at the subhuman race present and asked, "Is there anything you want to ask?"
Just ask me questions. ”"I have a question."
One of the Green Beasts in the team raised his hand and said, "How long are the 1 meters, 10 centimeters, and 20 centimeters you just mentioned?"
I don't have that concept. ”Sweat!
Actually want to explain this.The lizardman didn't mean to despise the green beast clan, he didn't know how long a meter and a centimeter were before, and he only knew it after studying in Frontier Town.No wonder the leader of the alliance said that the educated population is the high-quality labor force, and the efficiency is far higher than that of the uneducated population, and if this is the case, the lizardmen suddenly understood what Owen had said before.Walking to the wooden cart, the lizardman picked up a bundle of long ropes, held it up, and said, "This is the tool you will use to draw the edges of the square, and there will be a mark on it every one meter, so you can use this bundle of rope to measure it then." ”With that, he turned and put the long rope back, and took out a wooden ruler from it, and showed it to the people."
And this wooden ruler, for your convenience, there are only two scales on it, ten centimeters and twenty centimeters."
It turned out that the tools were so well prepared, and the subhuman races present were now relieved.After the tools were all put back, the lizardman asked everyone again, "Any more questions?"
”"Yes!"
This time it was the hand raised by the Demon Snake Clan, and he spat out the letter."
Why does the grass square have to be 1×1 meter in size and 10 to 20 centimeters high?"
This question has nothing to do with work, but the lizardfolk don't mind explaining to them how the grass squares prevent wind and sand fixation.Flipping through the "Sand Control Plan" in his hand, the lizardman quickly found the corresponding explanation and read it to everyone according to the above content."
After practice, it has been concluded that the sand control effect of other forms of grass walls, such as rectangles, triangles, prismatic shapes, circles, etc., is not as good as that of squares, that is, grass checkered sand barriers.Among them, the 1×1 meter in size and 10 to 20 cm high grass squares are the most effective in sand control. ”"The main reason is that the central part of the 1×1-meter-sized grass grid is only about 10 centimeters hollowed out by the vortex created by the air current.However, other specifications, such as the center of the grass grid of 2×2 meters and 2×3 meters, have been deeply eroded, and the effect of sand fixation and sand control is not good. ”"In addition, in general, the wind mainly carries sand particles within 10 centimeters of the surface, beyond which the amount of sand is transported is very small.Therefore, the height of the grass grid is between 10 and 20 centimeters, and there is no need to be higher than 20 centimeters, and less than 10 centimeters will lead to poor windbreak and sand fixation. ”Hearing this explanation, the smart subhuman race nodded understandingly, while the brainless subhuman race looked confused."
If you can understand it, you can understand it, and if you don't understand it, forget it."
Closing the booklet, the lizardmen don't insist that every subhuman must understand the principle of the grass square."
Anyway, if you don't know, it won't hinder your desertification control work."
Since the other party said so, those stupid subhuman races were very decisive to give up using their brains."
Next question."
The lizardman asked again."
That's, I'm so embarrassed."
The tall Red Devil scratched the back of his head and said, "You just talked about so many things in one breath, I heard it all the time, and I still don't know what to do, can you please demonstrate?"
”"Alas-" Hearing this, the lizardman couldn't help but sigh, the Red Devil is really a representative of thick limbs and simple minds.Sure enough, you can't expect all subhumans to figure out the process of making grass checkered sand barriers by listening to explanations.The lizardman had no choice but to walk over to another wooden cart, grab a handful of dried wheat straw, and demonstrate it to everyone."
You've all taken a good look at me."
The lizard man and the captain Wuming each demonstrated once, and after confirming that all the subhumans had figured it out, everyone started today's sand control work.Except for stopping for lunch at noon, everyone worked until the evening, when they packed up their things and prepared to return to the camp where they were resting.Raising his hand to wipe the sweat from his forehead, Wu Ming looked at the spectacular scene of the net-like grass squares joining together on the sand, and he felt a full sense of accomplishment in his heart."
I really hope that this will stop the Canaan Desert from continuing to erode northward, even if it is at a reduced rate.""
Absolutely."
Overhearing Wuming's words, the lizardman replied with a confident face, "I believe in the alliance leader, he has created so many miracles, and he will definitely be able to conquer the Canaan Desert as well." ”"Hmm."
Wuming nodded slightly, then turned away."
Let's go back to camp.".
