Datang: Li Shimin begged me to rebel

When the middle warehouse opened, Li Ke was still disappointed. The two warehouses in the middle were rice and hybrid rice.

Hybrid rice with strong yield is very strong in the modern industrial system, but it is useless in this era, because these hybrid rice is really just a reserve grain.

In other words, unlike wheat, it can be kept as a seed, it can only be used for food.

This is the real strategic reserve.

Li Ke quickly walked towards the remaining two warehouses. Isn't there still two warehouses?After opening the remaining two warehouses, Li Ke was relieved to save the optimized rice for planting.

Well, with these two things, it means that Datang's grain production will definitely enter an explosive stage next year.

This has nothing to do with fertilizers. Although land fertilizers are very important, chemical fertilizers are also very important, but in fact the improvement of crop seeds itself is also very important. Li Ke does not ask much for the increased yield of crops alone. It should be very easy to double the current simple right?

Many people underestimate crop improvement, and always think that the greatest role of modern grain production comes from chemical fertilizers, but this is not the case.

Before Li Ke came here, in the 80s, one kilogram of chemical fertilizer could increase the yield of crops by 1:20, but after entering the 21st century, the ratio of each kilogram of chemical fertilizer increased by only 1:5.Why is the production increase ratio of chemical fertilizers reduced so much?

This is naturally the improvement of grain seeds and the change of the nature of the land. In the case of such a large increase in production in the 80s, only 40 kilograms of chemical fertilizers were applied per hectare, but after the 21st century, this number reached 400 kilograms, an expansion of ten times.

But from this point of view, we know that the impact of chemical fertilizers on increasing production is far less than that of grain improvement, and the more chemical fertilizers, the better.

Excessive fertilization will cause the land to completely degrade, and it is even possible to turn it into dead soil.

Therefore, chemical fertilizers are never decisive. Even without chemical fertilizers, Li Ke thinks it should be no problem to reach [-]% of the production of modern fine varieties after planting in Datang.

At least, if you have to worry about fertility, the land in the Tang Dynasty was 1000 years less than the modern ones!

Coupled with the continuous popularization of Quyuan plows and columbine carts this year, when these iron tools begin to become popular, it means that the efficiency and depth of farming will be greatly improved, and the output of grain will also increase.

Therefore, the grain output of Datang will definitely increase explosively next year. When the grain output increases, the people's incidental industries will increase, such as making various drinks and snacks with grain, and raising poultry and livestock, etc. A complete industrial chain will be formed.

Alcohol isn't just for drinking, after all.

It can also be said that from now on, Datang has finally completely got rid of the food crisis.

At least with the current population and the current grain and farming machines, it is impossible for Datang to be short of food.

After reading this, Li Ke did not forget about the underground. The underground should continue to extend, but he doesn't know what will be stored underneath.

Skillfully entering the underground warehouse, the previously long passage finally extended again, and this time Li Ke walked forward for a short time, and found that there was a downward step in the front passage. When Li Ke walked down this step, He was stunned.

Below is a wider space, which...seems to be higher than the original warehouse above, which...is actually an air-raid shelter?Li Ke quickly saw the problem here from the markings on the wall.

This is a civil air defense facility. In addition to the corridor passage in the middle, there are also large rooms isolated on both sides, and these rooms are stocked with various simple daily necessities.

And Li Ke quickly found the reserve warehouses in these civil air defense facilities, but after seeing these reserve warehouses, Li Ke smiled bitterly. This thing is indeed a national strategic reserve, but it is useless to him now.

There are a large number of gas masks in one warehouse, while the other warehouse has three defense suits.

The number of these reserves is not particularly large, and the largest number of reserves is strategic food.

The shelf life is 20 years. In fact, the reserve cans and compressed biscuits that can be eaten after 30 years.This is the real strategic food, more than half of the cans in these warehouses are these, but Li Ke also found some new ones and a small half of the cans.

The shelf life of this small half of the reserve cans is 5 years, obviously it has just been reserved.

As for those with a shelf life of 20 years, Li Ke probably looked at them, and the production date has probably been more than ten years since he traveled through time.

It is estimated that the follow-up should be gradually replaced by cans with a shelf life of 5 years.

Preservatives must be added to the 20-year shelf life. For these strategic grain reserves, don’t say that preservatives are unhealthy. This stuff doesn’t consider that at all.

There are complete living facilities in the entire air-raid shelter, such as the drinking water system, which should be a drinking water system that directly extracts groundwater, but there is no electricity or the inside is still, Li Ke does not know how these things work.

Speaking of which, Li Ke was quite interested in seeing this civil defense measure, because he had never seen this thing before.

Those air-raid shelters that are open to the outside world are different. Those air-raid shelters are not of the same level as these air-raid shelters. Civilian air-raid shelters only have short-term self-sustaining capabilities. They are preset to prevent bombing and other situations, and do not allow people to survive for a long time.

But this air-raid shelter, combined with the strategic reserve warehouse on the ground, should be similar to a long-term self-sustaining underground base.

At present, there are still a lot of things that have not been unlocked, but to be honest, Li Ke thinks that these unlocked things are of no use to him, mainly because the current Datang... really doesn't lack anything.

And those things that are missing can't be directly replenished by providing materials at all, it will take time to proceed slowly.

So this air-raid shelter, Li Ke, just came in to have a look. When he found something new, he just didn’t find the weapon arsenal he wanted most. There are indeed armed police forces stationed around the warehouse.

Under special circumstances, after the armed police force withdrew, weapons would naturally be available.Large weapons cannot be stored in underground warehouses, but light weapons are unnecessary, so it can be said.

But for the wheat and rice, he had to take the time to find an outside warehouse and release them, so that someone could arrange planting.

There is no way to plant it this year, and it should be fine next year, but rice is no problem at all in some places in the south where three crops and two crops are grown.
