Chapter 494

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

Although the term "ecological greenhouse" has been used for a long time, and some people have been studying ecological agriculture and greenhouse planting before the meteorite fall, and there is no research combining the two, these ecological greenhouses are totally different from the ecological greenhouses in the research center.

Before the disaster, the so-called ecological greenhouse was a system composed of various plants planted in the greenhouse, various animals, microorganisms and various natural factors.

Although it can also form a relatively stable ecological cycle, most of the sunlight, air and water need to be imported from the outside world.

In particular, the most important sunshine, which can almost be said to be an indispensable resource for all agricultural production before the disaster.

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

Without sunlight, it is a huge blow to the whole agriculture. People have to use artificial light to provide light for crops in a way that consumes a lot of energy.

For the past ecological greenhouse, such impact and blow is fatal.

So Chen Xin would like to do research on ecological agriculture before, and build an ecological greenhouse that can adapt to the current environment.

Fortunately, this research is very smooth. After all, it has the research foundation of the original ecological greenhouse, and now there are geothermal power stations to ensure the energy supply and the warmth of the greenhouse. It is not very difficult to adjust the mode of the original ecological greenhouse under the condition that all conditions are complete, so that it can adapt to the existing environment.

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

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

And after these greenhouses were built, they soon played their role and began to produce a variety of agricultural products stably.

However, most of them are fruits and vegetables. Poultry and fish raised in greenhouses are not produced at the first time because of the time, so they need to be raised for a period of time to provide meat.

As for the most important food crops, rice was chosen at the beginning.

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

Planting more than two kinds of main food crops rashly will occupy a lot of limited resources in greenhouse.

Now, no more than in the past, after the loss of sunlight and major precipitation, especially the destruction of surface vegetation, the nutrients that the soil can provide have become limited. The cultivation of greenhouse must consider the overall ecological cycle.

Although it is not that it is not impossible to plant a variety of major food crops by artificial supplement to produce a large amount of food, and the country does do so in some places to obtain a large amount of food, this method is still contrary to the purpose of ecological agriculture.

After all, the purpose of ecological agriculture research is to restore the destroyed environment of Bluestar in the future, and rebuild the Bluestar ecology. If we use the method of fishing with all our efforts, although it can really solve the immediate problem, it is not a long-term plan.

Therefore, even if the country needs a lot of grain now, it still supports Chen Xin's ecological greenhouses instead of using a way more similar to traditional agriculture, relying on artificial input of chemical fertilizer, light, water and other conditions to produce grain on a large scale.

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

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

Although there is little difference now, there is a strong desire for ChiYan people. Since rice has been cultivated well, it is impossible to give up wheat.

Chen Xin knows that Professor Li and his colleagues are studying the wheat planting system recently, but he thought it would take some time, but he didn't expect that they really gave him a big surprise.

When Chen xinlai 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 and said hello to the old professor. Then he 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. It's estimated that the yield per mu will be 1000 Jin!" Professor Li is very happy about the bumper harvest of wheat in front of him. When Chen Xin asked, he said happily, "we didn't interplant this batch of wheat for the sake of safety. Now that we can guarantee the yield, we can start the experiment of Interplanting Wheat with other crops in the next step."

Wheat interplanting is a very common way of wheat planting before the disaster. Chen Xin also learned about the relevant technology for the sake of ecological greenhouse. At this time, he was surprised to hear Professor Li say so.

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

"No, it's different. Traditional interplanting is really to solve the problem that wheat can only meet the requirement of one crop a year due to the lack of light and temperature in some areas of China. Interplanting other crops reduces the competition for light and temperature under the condition of two crops a year." Chen Xin's problem is just Professor Li's professional scope, which naturally makes the old professor want to explain to Chen Xin.

He took Chen xinlai to a piece of wheat that had not been harvested, pointed to the space of the root part of the wheat plant, and said to him, "the ecological greenhouse planting that we are using now can provide sufficient light and temperature, so the purpose of interplanting is not to reduce the competition for light and temperature, but to make full use of the planting space, At the same time, increase the grain yield per unit area.

Now the traditional planting spacing is adopted for these wheat, and then we will adjust the spacing wider. Although the wheat planted will be reduced, the total grain yield per unit area can be increased by interplanting other crops, so interplanting is still very meaningful! "
