The Middle Ages from One Thousand and One Nights

If Petra Ancient City is on the mountain valley, about 80 kilometers of position is the dead sea sincerity.

The salt concentration in the dead sea is about ten times the ordinary sea, so the salt storage is very rich, and it is also very easy to form minerals such as saline halide and photogenous oxide. And the most important thing is that refining potash (potassium carbonate) will become Easy relaxed.

I believe that students who have learned junior high school should be able to think that potassium carbonate [K2CO3] and calcium phosphate [CA3 (PO4) 2] What reactions occur in liquid --calcium ions and carbonate to produce a precipitate, in which in water Leave potassium ions and phosphate ions.

But unfortunately, the prepaid tri potassium is directly used as a chemical fertilizer, and the effect is not too good, but it can be used to make fire protection materials and fire clothing. The calcium phosphate itself can only replenish phosphorus, and excessive calcium may lead to land strips.

As we all know, crops want to grow up healthily, the main elements that need to be added are nitrogen, phosphorus, potassium ... Of course, do not add to less than two meters,

Considering that it is necessary to produce chemical fertilizers to use the peasants, rather than getting a pile of urea, calcium phosphate, potassium chloride, so that the large number does not know the calculation ratio of farmers, Alibaba can only choose to make Compound fertilizer.

However, if he wants to produce a famous high-efficiency compound fertilizer-phosphonate in the later generations, Alibaba also needs to be used to use phosphoric acid.

Want to use a phosphoric acid, Alibaba must use strong inorganic acid to solve the calcium phosphate minerals of Jordan, and is also called wet method, as for other methods, it is unrealistic.

However, the problem is that the two alkali, the two alkali is still good, but the three sulfuric acid, hydrochloric acid is still nitric acid, and it is too difficult to produce large-scale production in the craft level of the medieval.

If sulfuric acid is only efficient and pollution, the synthetic ammonia industry required to produce hydrochloric acid and nitric acid is a caravan in front of Alibaba. There is no qualified and stable, homogeneous steel, you want to make what large chemical equipment can only stay on paper.

Therefore, only sulfuric acid can be used ... Although it is polluted.

Mineral species in the Middle East may still have a lack, but sulfur is absolutely not less.

After thinking about what you have to do, Alibaba has a idle heart and look at your own house ---

It's really good to live in the seven miracles of the world!

......

In recent days, the residents of Petra Ancient City know that there is such a thing --- a new elaston dropped over their head.

After you know this, these residents are still quite uneasy - because they cultivate the land, the jurisprudence is not part of them.

The land poured in the mountains in the mountains, and there is also the land of the water left by the former people, and they have never been known for the outside.

Therefore, these Belids suffered from accidentally found that there is such a peach source in the middle of the South Syrian Valley, they will move.

They have always declared that the mountains are not in the mountains. The food in the residents is still not enough to eat cloud clouds, trying to escape high agricultural tax, and mislead taxes, let him collect the head tax.

They succeeded - because the location is too remote, and the rock wall valley area is too poor, even the taxle of the Apula Empire is too lazy to run the past, completely according to the number of cultivated land, which is submitted.

This happens to the burden on them, but now is coming.

If Alibaba is true, keep them in the cultivated land they drive according to the number of tax books, then the farmland that claims to be owned by himself, then these farmers have completely no way - who makes them do not have these land Taxation?

As for acknowledgment error, this is not need to think --- To know in the teaching method, this land is the Holy Spirit, "The Leaders of the People" just replaced the Holy Spirit in managing the land. You dare to deceive the leaders of the people, that is, deceive the Holy Spirit. This cat teaching party, the sect, although there are many, but there is no sect thinking that the sacred spirits are not sinned. If you want to die, you can try it.

Seeing property may be lost, these poor mountains and evil spirits have even disgusting born born, wanting to use food as a employment fee, say some robber outside the desert, come in, to drop the landlord on the head, then Push responsibility to the outer robber.

But when they saw the seventy-hundred people, they were all in one. It is not your own affordable.

As for it, don't think about it, don't think - I can't do it, and even if I entered the Petra's ancient city, she is a relationship, Wanfu, but people are blocked in your door, the same is also a husband, Wanfu what! The light is to enclose you, so that you have no salt to eat enough.

It seems that it can only be accepted, after the mountains privately discuss, it is not laminated, and it is full.

If Alibaba knew that these mountain people thought, they will be furious, saying "There is always a kind of people who want to be humble".

But now Alibaba, I really didn't put the output of this land in my heart.

In the milders, the unrestfuling gaze, Alibaba took a few tens of people and patrolling the cultivated land of these peasants.

"Well? It seems to be more than the tax book?" Alibaba picked the eyebrows.

Although this is more, when he seems to look at his own balance treasure with middle school students, it is found that there is only three dollars with expectations, but there are nine pieces, nothing more than buying two bottles of cola.

I heard him saying, the family next to him couldn't hide, just have to stand up:

"Adults, some are recently opened, have not yet reported it!" He tried to do the final effort.

Alibaba jumped down the horse, with a hand-made decorative knife sword opened the earth block on the ground, revealing the wheat wheat buried below.

"It looks at least a season of wheat, right?" Alibaba squatted: "Do you want to check all the land?"

He wanted to understand what happened. From ancient times, there have been almost have seen the old man's pay tax (especially I believe in BOSS), and we have in this regard.

The length of the family - or is the village head, and the sweat on the forehead will take it out.

"This land is the leader of the people, I am in charge of the leader." Alibaba said slowly: "I am not here to become my farmers, nor to come to you. --- After all, I can't get a Diram.

However, I also understand that I really use it, I don't care what you have done before, now I will tell me which is your place, and then I am old, I will pay the 'Gizorn', I can do it.

Otherwise, because of the lack of the land, the corpse of the cleansing people will also know that you will also spread the plague, and now you are so hot now, how are you, right? "

If a soft in a soft, I don't know what to say, whether it is accompanied by an attachment, and the hidden danger of greed, now I can blame myself.

"Adults, can you discuss?" The old villagee tried to ask for mercy: "Adults got a great achievement of the Romans, and we also have a lot of people here. Since you can show your compassion about your interrogators, I believe you The people of the people will not be poor. You also saw it, the roads here are not good, use food to pay the 'Gizorn', there will be a large half loss on the road, so even the taxation is always unwilling. "

Alibaba is of course not to be difficult for these people, wait for the mine to recruit ore works, and these locals have to provide food. He just wants to take the opportunity to hit the other party and get a more favorable negotiation.

I can not exploit others, but I only keep this right in my own hands. Alibaba said.

Chapter 286 taking a shelf

Let the local residents are relieved that Ali Baba's great rods have gone high, but they put it softly.

After tapping, Alibaba put forward a solution to the migrant workers -

First of all, the land they reclamated must be declared to themselves, if there is any declaration, it is not the owner, and all Alibaba;

The land after declaration is owned by these mountain people, but the cropped crops in each year must use a wheelwise system - with wheat, alfalfa, winter wheat, and soybean a unit of two years.

When paying tax, all mountain people's duty tax and farm have been delivered upwards by Alibaba, and the mountain people directly in accordance with the food prices of Damascus or the pickled fish, in the form of grain, Alibaba Paying far taxs and does not need to pay people.

After paying your own food, you have enough food in their hands, Alibaba will have priority purchase rights, which is also based on Damascus or marinated fish, unless Alibaba has clearly put forward no longer Food, otherwise it is forbidden to sell food to foreign businessmen.

After selling a certain amount of food to Alibaba, Alibaba will give a ticket reward - these tickets can be used to exchange Alibaba is about to be in pickled fish, Damascus, Products, such as soap, lamp oil, fertilizers, etc. If you sell the number of foods in the year, you can also get Alibaba's hand made, extremely sharp chopper or hoe, and pick it.

After listening to Alibaba, the Petra's team was retired with doubt.

I have been tricking, and I'm looking at the mountain people in this side, I have gone through their village head and mix it together, I haven't been talked for a while.

In their view, the conditions given by Alibaba are really unscrowned - he makes everyone have to report the field area in the home, and it is really a little longer than before. But at the same time, they don't have to worry about taxlers, let alone Alibaba free people's darts, from now on, you can rest assured that children, generally don't lose.

The back part is the benefits of the local road channel - the previous tax payment, due to the taxes and food taxes, the food discount is really too low, so the mountain people can only choose to sell food. Come to pay taxes.

And if you want to sell grain tax, they will bear the loss of grain to the market, and the risks of being robbed on the road. If you sell it directly to the businessman, the counterpart price is really too embarrassing, they would rather go to the market to sell .

It is equivalent to saying that these farmers have in addition to the loss of the tax in the process of paying taxes, but also to accept the exploitation of a businessman, and pay the city when entering the city.
