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 existed a long time ago, some people have been studying ecological agriculture and greenhouse planting before the meteorite fell. There is not no research that combines the two, but these ecological greenhouses are similar to the ecological greenhouses in the research center. Comparison is completely different.
　　 The so-called ecological greenhouse before the disaster is a system composed of the interest and interdependence between the various plants grown in the greenhouse and the various animals, microorganisms and various natural factors in the greenhouse.
　　 Although it can also form a relatively stable ecological cycle, most of the sunlight, air and water need to rely on input from the outside.
　　 Especially the most important sunlight, which can almost be said to be an indispensable and important resource for all agricultural production before the disaster.
　　 But with the series of disasters caused by the meteorite impact and the impact of the recent volcanic eruption, the sunlight has long been gone, and even in the next ten years or so, it will only be restored to the low-light environment at most.
　　 Without sunlight, it would be a huge blow to agriculture as a whole. People have to use artificial light to provide sunlight for crops in a way that consumes a lot of energy.
　　 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 well. 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 greenhouse mode when all conditions are complete. It is not difficult to make it adapt to the current environment.
　　 In fact, after the scientific research center was built, the research of the ecological greenhouse has made good breakthroughs and progress under the team of Professor Li sent by the state, and the second phase of the expansion of the greenhouse has been carried out on this basis.
　　 In accordance with the model of the greenhouse, a new greenhouse was built on an original reform-through-labor farm in the urban area, allowing the original farm to play its role again.
　　 After these greenhouses were built, they quickly played their role and began to produce a variety of agricultural products steadily.
　　 However, it is mainly based on various fruits and vegetables. Poultry and fish raised in greenhouses are not produced in the first time because of time. They need to be kept for a period of time to be able to provide stable meat.
　　 As for the most important food crops, rice was chosen at the beginning.
　　 On the one hand, rice is the staple food in the south, and everyone is used to eating rice instead of noodles. On the other hand, the entire greenhouse is constructed for the purpose of forming a stable ecological cycle and realizing permanent cultivation.
　　 Planting two or more major food crops rashly will occupy a large amount of the limited resources in the greenhouse.
　　 Now is no better 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 planting of greenhouses must consider the overall ecological cycle.
Although it is not that we cannot rely on artificial supplementation to forcibly plant a variety of major food crops for mass production of food, the country does do this in some places to obtain a large amount of food, but this method is still in line with the purpose of ecological agriculture. Run in the opposite direction.
　　 After all, the purpose of studying ecological agriculture is to restore Blue Star’s destroyed environment and rebuild the Blue Star’s ecology in the future. If we use the method of exhausting all the water and fishing, although it can indeed solve the immediate urgent need, it is not a long-term plan or plan.
Therefore, even if the country needs a large amount of food, it still supports the ecological greenhouses developed by Chen Xin and others, instead of adopting a large number of methods that are more similar to traditional agriculture, relying on artificial fertilizers, light, water and other conditions to produce large-scale plants. 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 be able to enrich the types of food, but also to meet the differences in dietary structure between the north and the south of the Yan country.
　　 Although it seems that the difference is basically the same now, but the people who eat Yan are obsessed with it. Since rice has been well cultivated, it is impossible to give up wheat.
　　 Chen Xin knew that Professor Li and they had been studying the wheat planting system recently, but he originally thought it would take some time, but he did not expect that they would really give him a huge surprise.
　　 When Chen Xin came to the ecological greenhouse, Professor Li and his research team were watching mechanical harvesting of wheat.
　　 "Professor Li!" Chen Xin came to Professor Li's side, said hello to the old professor, looked at the wheat being harvested in front of him, and asked in surprise, "Is this batch of wheat ready for harvest?"
"Yes, it is growing very well, and the yield is expected to be 1,000 catties per mu!" Professor Li was happy for the harvest of wheat in front of him. Hearing Chen Xin's question, he replied happily: "We did not interplant this batch of wheat just to be on the safe side. Now that UU reading www.uukanshu.com can guarantee the yield, we can start the experiment of interplanting wheat and other crops in the next step!"
　　 Wheat interplanting is a very common wheat planting method before the disaster. Chen Xin has also learned about the relevant technology for the ecological greenhouse. At this time, he heard Professor Li say that but felt a little strange.
　　 So he asked Professor Li: "Professor, wheat interplanting is to make up for the lack of light and temperature of two crops a year in some areas? The ecological greenhouse has artificially provided light and temperature. There should be no need for interplanting, right?"
"No, this is different. Traditional interplanting is indeed to solve the problem of insufficient light and temperature in some areas of our country that wheat can only meet one crop a year. Interplanting other crops reduces the competition for light and temperature in the case of two crops a year. Question." Chen Xin's question 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 piece of unharvested wheat, pointed to the space where the rhizomes of the wheat plant existed, and said to him: "The ecological greenhouses we use now can provide sufficient light and temperature, so the purpose of interplanting It is not to reduce the competition between light and temperature, but to make 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, and then we will adjust the spacing to be wider. Although the planting of wheat will be reduced, but in the case of interplanting other crops, the total grain output per unit area can be increased. So interplanting is still very meaningful! "
