Doomsday Bunker Upgrade Chapter 493: Ecological planting

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, there were always people studying ecological agriculture and greenhouse planting, and there is not no research combining the two, but these ecological greenhouses and research centers here Compared with the ecological greenhouse, it is completely two 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.

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.

The absence of sunlight 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.

That's why Chen Xin 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 original ecological under the condition of all conditions. It is not difficult for the greenhouse model to adapt to the current environment.

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, so that the original farm could play a role again.

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

However, most of them are still vegetables and fruits. The poultry and fish raised in greenhouses are not produced immediately due to the relationship of time.

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 is not the same as 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 incompatible with ecological Agriculture has the opposite purpose.

After all, the purpose of studying ecological agriculture is to restore the destroyed environment of the Blue Star in the future and rebuild the Blue Star's ecology. 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 that Chen Xin and the others have built, instead of adopting a method more similar to traditional agriculture, relying on artificial input of chemical fertilizers, light, water and other conditions. to produce food on a large scale.

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 from 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 did not expect that they really gave him a huge surprise.

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

"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, it's growing very well, and the yield per mu is expected to be 1,000 catties!" Professor Li was very happy about the bumper wheat harvest in front of him, and when he heard Chen Xin's question, he replied happily: "We don't have this batch of wheat for the sake of safety. Intercropping ~IndoMTL.com~ Now that we can guarantee the yield, we can start the intercropping 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 the relevant technologies for the ecological greenhouse. He felt a little strange to hear Professor Li say this at this time.

So he asked Professor Li: "Professor, is intercropping 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 intercropping, right? "

"No, this is different. The traditional intercropping is indeed to solve the problem that wheat can only meet once a year due to insufficient light and temperature in some parts of our country. Interplanting other crops reduces the need for two crops a year. Wen's contention problem." Chen Xin's problem happened to be Professor Li's professional scope, which naturally made the old professor want to explain to Chen Xin.

He took Chen Xin to a field of wheat that had not yet been harvested, pointed to the space where the rhizomes of the wheat plant existed, and said to him: "The ecological greenhouse we are currently using can provide sufficient light and temperature, so The purpose of interplanting is not to reduce the competition for light and temperature, but to make more full use of the planting space and increase the grain yield per unit area.

Now these wheats use traditional planting spacing, and we will adjust the spacing wider later. Although the planted wheat will be reduced, the total grain output per unit area can be achieved when other crops are interplanted. Therefore, interplanting is still very meaningful! "
