Doomsday Bunker Upgrade

The ecological greenhouse is a research project established at the beginning of the establishment of the scientific research center.

Although the term ecological greenhouse has been around for a long time, before the meteorite fell, some people had been studying ecological agriculture and greenhouse planting. There is not no research combining the two, but these ecological greenhouses are similar to the ecological greenhouses in the research center. Well, it's two completely different things.

Before the disaster, the so-called ecological greenhouse is a system composed of the interests and interdependence between various plants grown in the greenhouse and various animals, microorganisms and various natural factors in the greenhouse.

Although a relatively stable ecological cycle can be formed, most of the sunlight, air and water need to be input from the outside world.

Especially the most important sunlight, which is almost an indispensable and important resource for all agricultural production before the disaster.

However, with the series of disasters caused by the meteorite impact and the impact of the recent volcanic eruption, the sunlight has long disappeared, and even in the next decade or so, it can only return to a low-light environment at most.

Without sunlight, it would be a huge blow to agriculture as a whole, and people would have to use artificial light to illuminate crops in energy-intensive ways.

For the ecological greenhouses in the past, such impacts and blows were fatal.

Therefore, Chen Xin only wanted to conduct research on ecological agriculture and build an ecological greenhouse that can adapt to the current environment.

Fortunately, this research went very smoothly. After all, it has the research foundation of the original ecological greenhouse, and now there is a geothermal power station to ensure the energy supply and the warmth of the greenhouse, and adjust the model of the original ecological greenhouse under the condition of all conditions. , so that it can adapt to the current environment is not a difficult thing.

In fact, after the construction of the scientific research center, the research on the ecological greenhouse has made good breakthroughs and progress under the team led by Professor Li sent by the state, and based on this, the second phase of the expansion of the greenhouse has been carried out.

And according to the model of the greenhouse, a new greenhouse was built in an original labor reform farm in the urban area, which made the original farm play its role again.

After these greenhouses were built, they quickly played their role and began to produce various agricultural products stably.

However, most of them are still vegetables and fruits. The poultry and fish raised in greenhouses are not produced immediately due to the relationship between time and need to be raised for a period of time to be able to provide meat stably.

As for the most important food crop, rice was initially chosen.

On the one hand, rice is the staple food in the southern region, and everyone is used to eating rice instead of noodles. On the other hand, the entire greenhouse is built for the purpose of forming a stable ecological cycle and realizing permanent cultivation.

Planting more than two main food crops rashly will occupy a large amount of limited resources in the greenhouse.

Now than in the past, after the loss of sunlight and main precipitation, especially the destruction of surface vegetation, the nutrients that the soil can provide becomes limited. The planting of greenhouses must consider the overall ecological cycle.

Although it is not impossible to forcibly plant a variety of major food crops by artificial supplementation to produce food in large quantities, and the country does do this in some places to obtain a large amount of food, this method is still in line with the purpose of ecological agriculture. The opposite.

After all, the purpose of studying eco-agriculture is to restore the destroyed environment of Blue Star and rebuild the Blue Star's ecology in the future. If we adopt the method of depleting the lake and fishing, although it can indeed solve the urgent need, it is not a long-term plan and plan.

Therefore, even if the country needs a lot of food now, it still supports the ecological greenhouses built by Chen Xin and the others, instead of adopting a method more similar to traditional agriculture, relying on artificial input of chemical fertilizers, light, water and other conditions to large-scale large-scale produce food.

However, after realizing the rice-based ecological planting system, the team led by Professor Li also began to study another wheat-based planting system.

This is mainly to enrich the variety of food, but also to meet the differences in dietary structure between the north and south of the Yan Kingdom.

Although now, the difference is basically not much difference, but there is an obsession with eating people in the Yan Kingdom. Since rice can be well cultivated, it is impossible to give up wheat.

Chen Xin knew that Professor Li and the others were currently researching the wheat planting system, but he originally thought it would take some time, but he didn't expect that they really gave him a huge surprise.

When Chen Xin came to the ecological greenhouse, Professor Li was watching the mechanical harvesting of wheat with his research team.

"Professor Li!" Chen Xin came to Professor Li's side, greeted the old professor, looked at the wheat being harvested in front of him, and asked in surprise, "Is this batch of wheat ready to be harvested?"

"Yes, the growth is very good, and the yield per mu is expected to be 1,000 catties!" Professor Li was delighted with the bumper wheat harvest in front of him, and when he heard Chen Xin's question, he replied happily: "We did not interplant this batch of wheat for the sake of safety. Now that the yield can be guaranteed, we can start the interplanting experiment of wheat and other crops in the next step!"

Wheat intercropping was a common way of planting wheat before the disaster. Chen Xin had also learned about related technologies for the ecological greenhouse, but it was a little strange to hear Professor Li say this at this time.

So he asked Professor Li: "Professor, is the interplanting of wheat to make up for the lack of light and temperature of two crops a year in some areas? The ecological greenhouse has artificial light and temperature, so there should be no need for interplanting, right?"

"No, this is different. The traditional intercropping is indeed to solve the problem that wheat can only be harvested once a year due to insufficient light and temperature in some parts of our country. Interplant other crops to reduce the competition for light and temperature in the case of two crops a year. Problem." Chen Xin's question happened to be Professor Li's professional scope, which naturally made the old professor want to explain it to Chen Xin.

He took Chen Xin to a field of unharvested wheat, pointed to the space where the rhizomes of the wheat plant existed, and said to him: "The ecological greenhouse we are using now can provide sufficient light and temperature, so the purpose of interplanting is It is not to reduce the competition for light and temperature, but to make more full use of the planting space and at the same time increase the grain output per unit area.

Now these wheats use the traditional planting spacing. Later, we will adjust the spacing to be wider. Although the planted wheat will be reduced, the total grain output per unit area can be increased when other crops are interplanted. So it is still very meaningful to interplant! "
