"The reservoir is very useful, these trees we planted can lock in the water, and this reservoir can retain the surface water, provide water to the trees and us during the dry season, reduce the dependence on groundwater, and in the future we can also get a lot of pond mud to improve the soil quality of the farm, which is a long-term plan and it is worth the investment." Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Although Azak was still a little unimpressed, seeing that Lin Quan valued this reservoir so much, he couldn't continue to say anything.

20,000 seedlings are not much, but it is impossible to plant them all at once, as before, the 20,000 seedlings are divided into four batches, and 5,000 seedlings are planted each time, and all of them are planted in two weeks.

The workers began to devote themselves to the previous work of planting trees, and after the previous experience, they have become very proficient in this kind of work, compared to the batch of trees planted at the beginning, they now know more, such as digging the depth of the pit should not be too shallow, not too deep, and should be adjusted according to the height of the sapling.

The specific heat capacity in the desert area is too poor, the sunlight hits the sand and forms a strong scattering, and the temperature on the surface of the sand is the highest after roasting, and under the sand, the lower the temperature, so the pit is dug deeper, the root system of the sapling will not be burned, if the temperature is too high, these delicate saplings will definitely not survive, especially now is the hottest season of the year.

But this pit can not be dug too deep, because the height of the sapling is limited, after the pit is dug too deep, the height of the branches and leaves outside the sapling is not enough, as mentioned earlier, the surface temperature of the gravel is the highest, and the closer to the ground, the more severe the scattering of the gravel, and the higher the air temperature, so the young leaves of the sapling are too close to the ground will be quickly scorched, and only the trunk can withstand this temperature, and the trunk also needs to do some protective measures, just like brushing the tree with lime in winter, but this time the brush is not lime, but mud！

These wet mud can absorb heat at the beginning, evaporate the water to dissipate heat, and when the water has evaporated, the trunk of the sapling will be covered with a layer of dry mud, which is equivalent to dressing the sapling, even in the daytime, it can reduce the temperature of the sapling.

The workers also changed the watering method according to this arrangement, and used to water the roots, but now they have to water along the trunk of the tree, not too fast, so as not to wash away the mud, and after the mud absorbs the water, it can return to the original evaporative and heat dissipation working mode, which can continue to protect these young saplings.

But there's a problem with this, and that's that the moisture is depleted too quickly!

This watering method is more wasteful of water resources, and the plant absorption and utilization rate is not very high, but the evaporation rate is very high, so the labor intensity of the workers becomes higher, and the water consumption is also higher.

But now Lin Quan doesn't care much about this matter, although this is a desert, but the north is the Tailu River, the Tailu River is about to be cut off, while there is still water in the river, he doesn't care how much he uses, but if the Tailu River is broken, he can't afford to use it like this, although the groundwater is abundant, but if some are too fast, the well water still can't support it.

Steiger hasn't been here since the saplings were sent, so this guy can't fulfill his requirements and hides and doesn't dare to see himself, right?

Lin Quan slandered in his heart, but he had to come sooner or later, and at least he still did some things, such as the pickup truck, this is a new car, although the price is not expensive, only a few thousand dollars, but this at least represents an attitude of his, he is not perfunctory Lin Quan.

Calculating the time, Lin Quan has been here for almost half a year, he has tanned a lot in the past half a year, the sun in Africa is very scorching, although this is not an equatorial region, but the sun is still very strong, ultraviolet rays are also very strong, the first few months of coming here, he has been sunburned several layers of skin.

There was one guy who was even more unlucky than him.

That's Wangcai!

Whether Wangcai is a German Shepherd in the end, Lin Quan is now more and more suspicious, Denise said that it is a German Shepherd, but the dog lover Li wants to say that it is not, and there are two military dogs in Zhao Cheng's army, those two military dogs Lin Quan has seen, it is said to be a purebred German Shepherd, but there is a relatively big difference in appearance compared to Wangcai, first of all, from the hair, Wangcai's hair is black and shiny, although the German Shepherd also has a whole body of black dogs, but the number is not very many, yellow and black variegated are more common.

And the difference in size between the two dogs is too big, Wangcai is nearly one meter tall, more than 30 centimeters taller than the German Shepherd, standing next to it is like comparing adults and children, the difference is too obvious.

But it's not Demu, it doesn't matter, this guy is very smart, it is estimated that he is a more powerful breed than Demu!

Otherwise, Sir Frydon wouldn't have thought of it as a treasure in the first place.

Wangcai's hair is pure black, which is very useful after nightfall, and it is difficult to be found if you drill into the night, and the stealth performance is excellent.

But in the daytime, this goods are miserable, and you can't go out at all, and you don't want to be abused by the sun.

Black things absorb light, and some of them heat up, which everyone knows, and in summer, everyone will choose to wear light-colored clothes, the closer to white, the better, because white clothes reflect all the light, and black clothes are all taken in order and absorbed, so the light-colored ones are cooler, and the black ones are hotter.

People can change clothes, but dogs can't change clothes, they only have a body of fur, change can not live, but the dog has no sweat glands, can only rely on the tongue to dissipate heat, which is very disadvantageous.

Originally, the temperature was relatively high in TSNY, but it was not a desert area, there was a lot of green vegetation, and there were a lot of tall plants in the yard left by the British.

But here, it's miserable, it's all desert, there are no trees, so it doesn't want to go out all day, it only wants to stay at home, it's sick and listless during the day, and it's willing to go out at night.

So every night Lin Quan will take it out to patrol the forest, both to be able to give himself courage, after all, the desert is empty, a gust of wind at night is very scary, the dog's senses are more sensitive, and the ability to find danger is stronger than people, so it can be courageous; and by the way, you can also take it out to wander and spread, so as not to make it sick after being stuffy at home for a long time.
