"This place can't be avoided, and there are no other good places around, what should I do?"

Lin Quan was a little helpless, people are not as good as heaven, if this small basin is in China, then it will not be a problem at all, and a team of engineers will come over, drive the excavator over, and fill it up in three or two days! But in Niger, this kind of thing is probably not possible, because if you do this, the budget or something will be exceeded. Pen "Fun" Pavilion www.biquge.info

"Then do you think there is any way to solve this problem? If you need any support, just ask!"

Steiger's helplessness is also a little helpless, at this time he can only pin his hopes on Lin Quan, he himself is really out of luck anyway, and he also thought of the way that Lin Quan thought of but didn't say, but just like Lin Quan didn't say it, this matter can only be thought about in his heart, and there is no way to achieve it, because they don't have enough funds.

"Well, in this case, we can arrange it into a double-layered, mask-type shelterbelt!"

Lin Quan took a piece of paper and roughly drew on the paper, the painting teacher died early, and the things he drew were not much different from the ghost painting peach talismans, and he could barely see it.

"W-is this going to work?"

It took a lot of effort for Steiger to finally understand what Lin Quan meant, his plan was to start from both sides, plant a row of trees, and then when he reached the edge of this small basin, he would separate them again, plant an arc-shaped forest along the edge of the basin to the front, close to the mountain pass, and then add a forest like this in the back, just like a mask, which could cover the mouth of the small basin.

"Theoretically feasible, although the arc formation is not too dense for sand control, but because there are two layers of trees in front and back, the density can be guaranteed, and the front layer of trees will also slow down these winds, and then the trees behind can easily stop them!"

The general anti-sand forests are arranged in three layers, as the third line of defense, they also need to divide labor, but in Niger, the forest does not have this condition, there are too many mountains near Niamey, originally these winds from the north will slow down after passing through these mountains, and will be blocked partially, but because after crossing the peaks, they are accelerating in the process of descending, and the dust on the mountains will be rolled up by them again, so if the position of a line of defense is well chosen, the effect is no less than that of the three lines of defense.

"But in this case, what we calculated before is wrong, and the number of forests needs to be recalculated, at least doubled!"

The small basin is arc-shaped in front and back, and there are two more, which means that the planting is no longer one diameter, but a whole circle, so the number of saplings that need to be planted should be greatly increased.

Steiger hesitated, they had a big problem with funding, and no one knew how effective this anti-sarin was, the reason why Angus only agreed to build a third line of defense was because of lack of funds, and they also wanted to use this successful line of defense to sell their plan to the national leadership, and wanted to get their support, and then be able to allocate funds to complete other construction.

And what Lin Quan has to do now is to complete a line of defense, achieve some results, and then use it as an exhibit for them to sell.

But even for this exhibit, they don't really want to spend money, at least not too much.

After hearing Lin Quan's words, Steiger thought for a while and said: "Let's take a look first! If you have to do this, then try to reduce the cost, Mr. Lin, you have been to our government office building, you know the current economic situation of our Ministry of Agriculture, if there are too many funds, we can't come up with it, and this project does not have the support of the United Nations, so we don't have to reimburse anyone or anything, all of them have to be paid out of our own pockets, we can't come up with so much money, can you see if you can think of other ways?"

Lin Quan held his chin and thought for a while, the reason that Steiger said made him despise it, and he wanted the horse to run, and he wanted the horse not to eat grass, how could there be such a good thing in the world!

But even if the government reduces investment, it can still make a lot of money, and how much can it earn!

Next year, whatever they want, anyway, if the money is not enough, Lin Quan resolutely does not participate, let you say that the sky is broken, he made up his mind, if you don't see the rabbit, you don't scatter the eagle, you put it on your hot face, but the other people are not in a hurry, it seems that it is better to wait until others come to ask for their own more reliable, the asking price is better, and the things are simpler, it's really boring like this, you have to learn a lesson next year, so as not to ask for trouble, and you can't get paid for doing things, that's really a loss to grandma's house!

"Okay, then push this row of trees forward by 600 meters, and plant it directly at the downwind position, then you can save about 60% of the saplings, but the effect is estimated to be half discounted, you can calculate it yourself! See what you want to do, if you think about it, let me know when the time comes, okay?"

After Lin Quan finished speaking, he took his GPS receiver and walked towards Azak's position, he was going to measure the width and slope of the downwind outlet, planting trees on the hillside needs to consider more than on flat ground.

In particular, this is still a desert area, and the survival of saplings cannot only rely on surface water, but also the aquifer, and the location and slope of the hillside make the saplings planted on it farther away from the aquifer than the saplings planted on flat land, in short, the survival rate is lower.

The location of this downwind outlet is not very wide, but the ground is very uneven, Lin Quan roughly estimated, almost 20,000 poplar trees are enough to plant, the conditions here are actually not very bad, at least there is a Karui River next to it, this river is smaller than the Tailu River, but because it is closer to the south, so the rainfall is more abundant, so the Karui River will not stop flowing in winter.

This is equivalent to providing a water source for planting here, with a water source, things will be much easier, because the location of the Karui River is in the river valley, so you can directly divert water and dig a channel, if the manpower is enough, Lin Quan feels that even if you don't have to wait for spring, now, even in winter, you can plant trees here.

There are also some villages here, the villages look dilapidated, but there are still a few wisps of smoke rising from them, which means that there are still people living in this village, and they still have some thin land on the beach of the Karui River, Lin Quan went to look at it, and found that the things they grow are relatively miscellaneous, corn, sorghum, wheat, cassava and other dry season crops can be seen here.

This made Lin Quan feel amazed, because the more varieties of crops planted, the more difficult it is to manage, and there are so many crops planted here, I don't understand what the farmers in that kind of land are thinking.
