Lin Quan was very happy when he saw the stagnant water on the farm. Pen "Fun" Pavilion www.biquge.info

The most lacking thing in the desert is the soil, although the plants can survive and grow in the sand as long as they have enough water, but the microorganisms have not been able to do this, the sand is easy to compact, and the ventilation is not very good, so it is not a good place for them to live, and the land is different, after having a loose soil layer, the oxygen in the air can enter the soil layer, and these microorganisms can survive.

When they get enough oxygen, their activity increases, which further loosens the soil.

The loose soil provides a very good place for these microorganisms to move, which allows them to break down some organic matter that plants cannot absorb, and then return it to various substances that plants can easily absorb, such as fertilizers and some metabolites that plants are relatively lacking.

For example, the fallen leaves of plants, which contain potassium, are needed for the growth of plants, but the content in the soil is not very rich, at this time, after the microorganisms decompose the leaves, the roots of the plants can also absorb these nutrients when they absorb water.

A layer of soil appeared on the surface of the farm, although it was only a thin layer, but this discovery still made Lin Quan very happy.

Generally, the soil contains sand, so the color of the land does not seem to distinguish much, but the water permeability of the sand is relatively strong, and the rainfall absorption is relatively fast, and the sand containing the soil will turn into mud when it rains, and the water is easy to retain, and then form surface water, and with surface water, some plants with shallow roots are easy to survive.

And the deeper the soil, the higher the chance that these plants will survive and will not die in the future.

It seems that this year to dig a batch of river mud from the Tailu River back, there is a lot of sediment washed down from the Gobi Desert, although the composition of the sand is relatively large, but because the river will be cut off, so when the river does not move, the sediment will settle down, the weight of the sand is heavier, so it is generally sunk in it, and the mud is relatively light, so it will be on it, so when digging, it is very good to dig a thin layer on it!

This is a technical job, Lin Quan didn't know this situation at the beginning, and then after his own summary, he found this thing, last year they dug a lot of sediment from the Tailu River, the first few times I only thought about the quantity, so I couldn't wait to send an excavator over, and the sediment dug back in the end was not much, and then it was much better after summarizing the experience a few times.

"Azak, take a few people, let's go to the Tailu River!"

Lin Quan thought that if it rained, the water level of the Tailu River might not rise, after all, the first time it rained, the rainfall in the upper reaches basically seeped into the ground, and if there was no rain flowing into the Tailu River, the water level of the Tailu River would not rise, and after a whole dry season, after six months of drought, the arid desert absorbed water very quickly.

Moreover, the temperature in the desert area during the day is too high, and the water evaporates quickly, and the water level of the Tailu River will not last long without continuous rainfall.

At this time, Lin Quan thought about the next thing that his vineyard was going to replant grapes!

In the past, because of the variety of grapes, the vineyard was almost useless by Lincoln, and the grapes in it could not be used to make wine, but if the vineyard was destroyed, Lin Quan also felt that it was too wasteful, and from the situation last year, tourists seem to like the vineyards here, everyone picks them here, weighs and sells them by themselves, and then they are interested in making their own wine, which is very attractive to them.

So Lin Quan still decided to keep this vineyard, anyway, the area is not very large, although it can't make wine, but it is also excellent to eat it simply as a fruit!

And for this reason, Lincoln asked to rebuild a vineyard, but the location he chose was not very good, which made Lin Quan a little nerve-wracking, he had been worrying about this matter for a while, and at this time he saw the water on the ground, he thought of something, so he decided to go to the Tailu River to have a look.

The Tailu River is a river in the north of Agadez, this river is a seasonal river, which means that it does not have water all year round, and the time it flows is only about two-fifths of the time of the year, and the rest of the time the river is broken.

The Tailu River originates from the mountain peak in northern Niger near Libya, this peak is still relatively high, more than 6,600 meters above sea level, what is the specific name, Lin Quan remembered it before, but now he has forgotten.

But it doesn't matter, the Tailu River originates from the foot of this peak anyway.

As you know, the higher the altitude, the thinner the local air and the lower the temperature, about every 1,000 meters above sea level, the temperature will drop by 6 degrees Celsius, and the temperature above the 6,000-meter mountain is below zero degrees Celsius, so this is a snow-capped mountain.

The snow on the snow-capped mountains will melt with the change of temperature, in the winter the range of ice and snow is relatively large, but in summer, the range of ice and snow is relatively small, and in the spring when the average temperature begins to rise, the snow on the iceberg melts to form a water source, which is the origin of most of the rivers, like the Yangtze River and the Yellow River in China, are originated from the plateau snow mountains.

However, there are not many sources of water for the icebergs, so there is a very unique landscape in the Tailu River, that is, there is water in the upper reaches, no water in the downstream, and the water stops intermittently in the middle reaches (the low water level in the middle reaches is relatively high), while Lin Quan is in the downstream, and the river disappears after flowing into the desert.

At present, the heavy rainfall has not yet appeared, and the melting of the iceberg snow has not reached the highest point, so the water source of the Tailu River is relatively small, and only when the rainfall becomes more in the rainy season, the snow melts upstream, and the water table rises so that the desert is saturated, the water source of the Tailu River will become abundant, so that it can form flowing water.

After hearing Lin Quan's words, Azak hurriedly found a dozen people, and then came to Roy, asked him to take a few guards as escorts, and the group drove along the canal to the Tailu River.

The Tailu River is a small river, this river is not wide, the widest part is only about 50 meters, this river is like a rift valley washed out of the desert area, when there is flowing water, it becomes a river, and when there is no flowing water, the riverbed becomes a deep ravine in the desert.

Lin Quanxing rushed to the edge of the riverbed to take a look, the riverbed was still dry, and there was no water in it!
