There are many types of phosphate rock.

However, according to the different formation factors and compositions, it is roughly divided into two large categories: apatite and phosphorite.

The phosphate mine near Yanggou Village is apatite phosphate ore.

This can be judged by the variety of colors of the ore and even the faint fragments of crystals in the rocks.

The finest apatite crystals can even be milled for gemstones.

Of course, the apatite crystals on this phosphate rock are clearly not up to the level of a gemstone.

But the existence of those glittering fine crystals is enough to show one thing - that is, the grade of this phosphate rock is extremely high!

These are all things that Zhang Ran has known for a long time.

If it weren't for this excellent phosphate mine, it would be impossible for him to move those profit-seeking businessmen to invest in this side when he was alleviating poverty, so that he would have enough confidence to take the unfinished political achievements to look at Kehua.

Zhang Ran would never have imagined that these things, which were used as political achievements and capital to seduce Kehua, would bring such great help to the development of the base area after returning to this era.

Only inferior ores need beneficiation, and for this high-quality mine, beneficiation is completely unnecessary.

The only processing required for these mined phosphate rocks is to concentrate some manpower to crush the mined phosphate rocks.

The purpose of this is, of course, to speed up the decomposition of phosphate rock when soaking with sulfuric acid, so as to get what Zhang Ran finally wanted to get after scrapping this large circle of effort - a precipitate containing a large amount of calcium phosphate and a small amount of impurities......

That is, the most basic crude phosphate fertilizer!

The phosphate fertilizer produced in this way is of course not as efficient as the industrially produced phosphate fertilizer.

But for this era of fertilizing fields in addition to farm manure or shaving dead branches or humus layers from the mountains, such phosphate fertilizer can almost be described as a fetish!

Now, with the exception of coking plants and copper smelters, almost everyone is doing the same thing, which is to mine phosphate rock, or to crush the mined phosphate rock with a small hammer.

A large soaking pond has long been excavated, and the surrounding area is reinforced with stones and other things to prevent leakage.

The crushed phosphate rock is poured into the soaking pond, and the large amount of sulfuric acid that has accumulated from the extraction these days is poured into it......

The rising smoke is like a steamer.

The next thing to do is to stir and wait......

The whole process takes about a few days.

At this time, Wang Changtian and Lu Yan, as well as the village party secretaries of various villages, were busy and crazy.

Because the phosphate fertilizer and ammonia fertilizer produced in advance are very limited, and all the crops are waiting for top dressing......

For these fertilizers, in the past few months, almost all the active laborers in the base have been revolving around it, mining copper ore and transporting copper ore, helping to transport the purchased coal back from the outside like ants moving, accumulating a lot of work.

Now, it's time for the detachment to fulfill their promise to exchange their labor for fertilizer!

Everyone wants to be the first to get fertilizer!

Because the best topdressing period is missed, the effect will definitely be greatly reduced.

It is impossible for anyone to understand this truth for the common people who have been dealing with crops since they became sensible.

To this end, Wang Changtian and Lu Yan came up with various methods to evaluate, who will take the first batch of fertilizer, who will take the second batch, and how much......

This is a great opportunity to strengthen the cohesion of the base area, and at the same time consolidate the weight of his own speech in the base area, although it is very troublesome, but Lu Yanwang Changtian, as well as the village party secretaries of each village, did not ask anyone for help, and handled it personally.

In this case, of course, Zhang Ran will not take the initiative to intervene.

He's now busy experimenting again.

The crude phosphate fertilizer prepared in advance for the experiment was divided into several small portions, and small plots of fields were fertilized separately and then observed.

The goal is still to get the best amount of fertilizer, not to cause a bad harvest because of too much, and not to think too little to achieve the best top dressing effect.

Ma Chengbang, Zhao Wanlin, Zheng Tianming and others are now chattering with Zhang Ran's ass every day.

According to the previous agreement, the people in the base area will exchange labor for fertilizer, and when the labor share is consumed, they will exchange food, money and goods for fertilizer or buy fertilizer.

When the purchase of these grain goods began to be exchanged for fertilizer, the detachment and them each took half of the proceeds.

But just relying on the base area, it is impossible to make too much money.

Therefore, Zhang Ran gave them all the power to promote and sell fertilizers outside the base area.

The detachment only demarcated the scope of export fertilizer and should not be too far away from the periphery of the base area, and the detachment did not care about other operational aspects, but only extracted 30% of the profits from the profits!

In fact, the detachment itself can do the sale of chemical fertilizer to the surrounding areas of the base area, relying on the role of chemical fertilizer, and there is no need for these landlords to earn an extra two percent.

But Zhang Ran always knew very well that the ultimate goal of the detachment was to fight against the Japanese army, not to make money.

If too much energy is involved in this aspect, it will inevitably affect the building of the detachment and thus the combat effectiveness of the detachment.

Handing over to these landlords will not only better bind them to the detachment, but also allow their own forces to form a barrier on the periphery of the base area, which will definitely be beneficial to the base area.

There is no need to be involved in these miscellaneous things, just continue to harvest money and grain, and give these landlords an image that is beneficial to them, Zhang Ran is naturally happy to do it.

Now Ma Chengbang and others are chasing Zhang Ran's ass and chattering, that is, when will they get the fertilizer prepared for them by the detachment.

Because of the limited production capacity, the fertilizer manufactured in the base area is not enough to supply the base area, and where can we afford to reserve another one for Ma Chengbang and others?

But what Ma Chengbang and others said is obviously true.

Although the use of chemical fertilizers, once the word of mouth spreads, the people on the periphery of the base area will rush to ask for this fertilizer.

But word-of-mouth communication always takes time, and the effect is not guaranteed, where is the reality of seeing is believing?

"Captain Zhang, my requirements are not high, you just give me 300 catties of phosphate fertilizer and 100 catties of ammonia fertilizer!"

Ma Chengbang begged: "I have done a good job in the experimental field over there in Yuanguang, and I have already greeted the people around there, let them see for themselves, how big is the difference between the yield of chemical fertilizer and the yield of no chemical fertilizer - you say this, if you don't give me chemical fertilizer, my experimental field will not increase production, and it will not affect the sales of chemical fertilizer in our detachment?" ”

"It's Zhang Ran brand fertilizer, Zhang Ran brand fertilizer - you can't tell the brand, are you embarrassed to ask Zhang Team for fertilizer?"

Zhao Wanlin, Zheng Tianming and other landlords relied on the strength of the crowd, and arched Ma Chengbang with a few buttocks, and said with a flattering face that he and others were not as greedy as the surnamed Ma, and they only needed 200 catties of phosphate fertilizer and 100 catties of ammonia fertilizer......

"Oh, I said gentlemen, can you just spare me?"

Zhang Ran spread his hands and said: "You don't know, in order to get the fertilizer as soon as possible, how many fights have we had in the past two days?" Shijiagou's Shi Wanzhong Village Party Secretary has been beaten several times, and now his eye sockets are still green, and he doesn't even know who beat him, do you also want me to beat people because of unfairness......

A few people begged again, obviously as long as Zhang Ran did not agree to set aside some fertilizer for them to expand the influence of fertilizer, they would never give up.

"If you want me to promise to give you a batch of sample fertilizers first, it's not impossible, but I also have the conditions!"

When the patience of a group of landlords was almost grinded, Zhang Ran spoke.

"Captain Zhang, our family is about to knock you out with such a bamboo pole and two bamboo poles......

The landlord of Ma Chengbang smiled bitterly when he heard this, but this time he didn't make all kinds of excuses like before, but said: "Forget it, anyway, you are used to being knocked by Captain Zhang, how much money do you want this time......

Anyway, now that the fertilizer has come out, they have also seen the effect of these experimental fields, as long as the popularity of the fertilizer is expanded, how much money can be earned back, so they don't care.

"This time, it's not about money!"

Zhang Ran had a straight face, and said solemnly: "I promise you, I only have one request, that is, the fertilizer that our detachment goes out must take the parity route, you can earn the money you should make, but you must not rely on strange goods to live and make black money everywhere!" ”

"Captain Zhang, don't worry about this!"

Hearing this request, several people immediately clapped their chests and said: "With this fertilizer factory, it will be difficult for us to make money in the future, so now, we want to make money while also making a good reputation......

Hearing this, Zhang Ran's heart calmed down a little.

He didn't want to come up with chemical fertilizer, but this chemical fertilizer has become a new means for these landlords to unite and exploit the surrounding people, and the gains outweigh the losses!

But in addition to this, Zhang Ran has another request!

That is, when necessary, the share of fertilizers that are now handed over to them according to the contract must be at the disposal of the detachment!

In the future, the base areas of the Eighth Route Army will be strictly blockaded by the Japanese army, and all kinds of materials will be scarce to the extreme, and the same will be true for food.

At such a time, if the limited resources cannot be given priority to the teams in the base areas, the combat effectiveness of the Eighth Route Army will be greatly weakened, which is tantamount to fueling the arrogance of the little devils in disguise.

That's something he didn't want to see.

Originally, Zhang Ran thought that Ma Chengbang and others would definitely not agree easily!

But the reaction of a group of landlords was unexpected by Zhang Ran - they patted their chests fiercely and said that if there was really that day, they would be obligated to do so - of course, even if it was a white strip, it would still be a beating.

"You guys finally have a bit of a patriotic capitalist!"

Seeing this scene, Zhang Ran was very pleased, he didn't want to admit that as long as it was possible, in fact, everyone had patriotic feelings.

He prefers to think that this group of landlords was moved by their noble personality because they had spared no effort in ideological propaganda for a while, which influenced these black-hearted landlords......

Otherwise, what sense of accomplishment is there?
