As a technician, it is a great honor to be able to participate in such a great project, and it will be recorded in my qualifications in the future, so that I can have the capital to brag to my children and grandchildren in the future, so that my family can be proud of myself!

This is even more commemorative than the previous participation in the pollution control of Wood Cutting Township, because it is a small collective, a small place, this is a big collective, a big place!

So, with this unprecedented enthusiasm, everyone quickly formed a team, their tasks were determined, and then they received a set of sand control packages from Wang Han: a speed potion, a retardation potion, and a fertile soil formula. Pen & Fun & Pavilion www.biquge.info

Everyone really wants to see how fast this speed potion is, and how slow this slowness potion is.

Wang Han also made a speed potion and a retardation potion himself, and found a small clay pot to try.

Well, let's plant ephedra, this is ripe.

……

The Speed Elixir is a dark purple water potion, while the Retardation Elixir is an earthy yellow water potion. The two potions were about the same size as the physical elixir, so Wang Han hesitated, considering their cost, the speed elixir did not pour on the root of the ephedra seedling, but carefully dripped on its top leaves.

After a few minutes, the speed potion was basically absorbed by the ephedra grass seedling, and he poured the retardation potion directly into the gravel.

After pouring it, when the retardation potion had completely penetrated, he buried it in the fertile soil formula.

Bless the fertile speed of this fertile soil recipe from being affected by the Retardation Elixir!

After doing all this, Wang Han endured and endured, but he didn't hold back after all, and logged into the farm to ask the senior housekeeper: "It's the same medicine, won't speed, slowness, and fertile soil affect each other?" ”

The senior butler quickly grinned, but in Wang Han's opinion, this smile looked like he was laughing at himself: "Respected master, the soil itself has no speed, it is only sticky. So Speed Flasks can't increase its speed. ”

"Sand and gravel is very slippery and not fixed, and when it is subjected to external forces, it rolls, and because of its slippery properties, its friction is very low, so it slides fast. At this point, the retardation potion creates a force field that slows its rolling. ”

The fertile soil formula only enhances the effective ingredients in the sand and gravel, which is equivalent to a nutrient, so it will not be affected by the sluggish agent. ”

OK, I've seen it for a long time.

I have to admit that the senior butler's explanation makes a lot of sense.

Each potion has a different surface of action, and it is only mistaken by their names.

So, wait!

……

Wang Han didn't wait long.

Speed potions are used on the human body and only last for a few minutes.

But when it was used on these plants, the ephedra seedlings that had been planted grew a lot the next morning, and Wang Han even doubled the root system of the plant!

And a little dirt has appeared on the surface of the sand and gravel below.

I'll go, it's only been a short afternoon and an evening.

Don't be too fast!

Wang Han hurriedly went to ask the other classmates again, but everyone looked at him with green eyes.

The growth rate and soil change rate of the groups selected Salix saxon were indeed much faster than those of Saxon and red willow.

Zhou Qing quickly puffed out his biceps towards Hu Lujing with murderous energy: "Boy, look how I beat you to the ground!" Facts have proved that the effect of Salix sand fixation is better than what you said about Halaxon and red willow! ”

"And our salix can be used for biomass power generation, which is an energy-grade war preparation material, and your Saxon wood and red willow are at most used as pasture grass, indirectly growing Cistanche, and it is just a luxury medicinal material! No matter which aspect it is, at present, we should first use Salix to transform the desert, and then consider the problem of medicinal materials when there is less desert and more land! ”

Hu Lujing was dumbfounded by Zhou Qing for the first time.

After Wang Han read everyone's observation records, he made a final decision: "Then, let's adjust the plan, in the early stage, use ninety percent of the land to bring and plant Salix, and so on to ensure that only half of the grown Salix is enough to supply the consumption of biomass power plants, and then replant the rest of the land with Halaxon and red willow, so as not to cut down these two plants in other desert areas and become extinct." Of course, it would be even better if Cistanche could be generated. ”

Next, each group was still responsible for starting the work, and Wang Han continued to observe his own samples.

As a result, Lingmiao Ecological Group gathered local herdsmen and workers transferred from China Construction Fourth Bureau to start a vigorous desert tree planting project.

First of all, they rented off-road vehicles to act as leg power, carrying groups of ecological commissioners and workers to the divided area, cutting down a large number of local native sand willows and distributing them as saplings.

These Salix seedlings will continue to be planted in the nearby sandy soil, and then the intern ecological commissioners will lead the intern ecological commissioners to promote growth and sand fixation with precious speed and retardation agents.

Wu Butong was personally responsible for the receipt and use of each tube of medicine, and tried to prevent the loss of these two miraculous medicines.

The business elites led by Xu Qiangguo are coordinating the elite construction team of China Construction Fourth Bureau to step up the pace of building biomass power plants, and strive to be able to use these salix plants before they grow into patches.

On the third day after the experiment, Director Zhang came all the way from the capital.

Wang Han was soon called back to his temporary office at Chahanhu and met with Director Zhang. After a short period of reminiscence, Wang Han's heart jumped when he heard Director Zhang's intention, and he was a little puzzled on the surface: "You mean that the satellite detected that a purple-red light band appeared in the dust storm in this desert, and suspected that there are some high-purity non-ferrous metals?" ”

"Yes. It could be gold, but it could also be copper, and this needs to be further sampled and analyzed. Director Zhang was very sure: "Originally, this matter was not in my charge, but the Metallurgical Bureau thought that I was familiar with you, and I also had a big project related to the Ministry of Defense recently, so the leader sent me to understand." ”

Defense?

Wang Han instinctively remembered bullets and shells.

He smiled and said, "How can you help me?" ”

Director Zhang was embarrassed: "The expert is not me, I am just here to contact you." If you've not been very busy lately, can you spare a day and we'll take some samples in the desert. ”

"Okay!" Wang Han said with a smile: "It just so happens that the tests that our company should do recently have been completed, and I will accompany you for one day." ”

He was still very satisfied with Director Zhang's behavior of coming to say hello first. After all, this place has already been bought by him, and if he really wants to do any research, he should also inform his owner first.

Director Zhang was also completely relieved. Wang Han's strength has increased greatly now, and Yu Changchun can sell the old in front of him, and the others are somewhat under pressure in their hearts. And this is another master who is not afraid of things, if he comes secretly and makes any moves, he will be discovered by this kid, and then he will make a fuss regardless of it, and it will be their gang that suffers.

Well, it's wrong, with this kid's keenness, as long as he and others come, he will definitely not be able to escape his attention, so just be generous.

Anyway, if there is really a copper vein, this kid will also have a share.
