Chapter 496: The meaning of ecological greenhouse

The ecological greenhouse of the scientific research center is not the same as

the traditional greenhouse, and it is also quite different from the ecological

greenhouse before the disaster.

The greenhouse in the traditional sense is mainly used to raise the

temperature and artificially change the growing environment of crops.

Although the ecological greenhouses before the disaster are different, they

are actually used for this purpose, but relatively speaking, they will be more

comprehensive in function.

Chen Xin remembers that according to the information he found, there are even

the kind of ecological greenhouses with solar panels that use solar power to

provide energy for the greenhouses and make full use of natural resources to

increase the yield of crops in the greenhouses.

But these are now impossible.

Including the new greenhouses built by the country. The most essential

difference between these newly built greenhouses after the disaster and the

past greenhouses lies in the walls.

Traditional greenhouses are mostly constructed with transparent films, which

are low-cost and easy to maintain. They use straw or heat-preserving quilts to

maintain the temperature. In the past, they were indeed sufficient and

sufficient heat preservation.

However, if you want to maintain the temperature in an environment of tens of

degrees below zero, this is not what traditional greenhouses can do. Even in

the past, ecological greenhouses used plexiglass, transparent plastics and the

like for building materials. The insulation performance of the materials has

not exceeded too much.

In the greenhouse of the scientific research center here, all four walls are

made of high-performance insulation materials as interlayers, the outer layer

is made of low-temperature resistant metal materials, and the inner layer is

made of composite materials. The three-layer structure can not only resist the

invasion of external cold, but also prevent the interior. Loss of temperature

and water vapor.

Because there is no sunlight outside, the current ecological greenhouse does

not consider the issue of light transmittance. Instead, it is necessary to

reduce the escape as much as possible in order to save.

In addition to the structural difference, the bigger difference lies in the

interior.

not only uses a variety of technologies such as soilless cultivation, three-

dimensional planting, and ecological agricultural breeding to upgrade the

original flat planting area to a solid planting system, but also forms a cycle

between various crops to form an organic whole.

With the continuous supplement of the three necessary conditions of light and

mild water, although the ecological greenhouse of the scientific research

center can not be said that it can be cultivated indefinitely, there will be

no problems for at least ten or twenty years.

The expected goal of the research team led by Professor Li is that there will

be no circulation problems within 50 years, and to ensure that the ecological

greenhouse can still operate normally without changing crops except for

mechanical maintenance.

As for the maintenance of the ecological greenhouse, it has been fully

mechanized with the help of Chen Xin.

Mechanical harvesting, mechanical seeding, mechanical irrigation, mechanical

feeding... In the entire ecological agriculture system, the parts that require

human labor have been replaced by mechanized operations under Chen Xin's will,

and everything has become automated.

In fact, the ecological greenhouse here in the scientific research center is

indeed fully automatic. It only needs to set the planting mode and ecological

system, provide the original crop seeds and animal seedlings, and ensure the

supply of light, temperature and water. The entire ecological greenhouse is

Able to operate on its own.

The 50 years of no problems that Professor Li pursued means that in addition

to mechanical failures, the entire ecological greenhouse can operate on its

own for 50 years without problems.

In order to achieve this goal, Professor Li and his team carefully selected

all crop seeds.

They did not choose those seeds that were artificially cultivated in the past

with high yield but could not inherit the traits for a long time. Instead,

they chose those seeds that had stable traits and could be seeded directly

without significant yield reduction.

Moreover, he has carried out meticulous research on the ecological dependence

of crops. Only then can the fully automated ecological greenhouse of the

current scientific research center be built.

The animal seedlings used in the ecological greenhouses are even better breeds

that have been bred by optimizing the traditional livestock seedlings with the

aid of the equipment used by Chen Xin to breed genetically modified wolf dogs.

It's just that animals are very different from plants. They need someone to

take care of them.

Although the automatic machinery of the ecological greenhouse can provide them

with the water and food necessary for survival, they still have to be dealt

with by humans if diseases or other conditions occur.

I have to say, this already has the flavor of automated agriculture in science

fiction.

The ecological greenhouse devoted to Professor Li and Chen Xin did not

disappoint them. Not only can they continue to maintain themselves, but they

can also produce fruits and vegetables, as well as a large number of food

crops and eggs every month. Agricultural and sideline products such as milk

and meat.

According to the calculations of Professor Chen Xin and Li, such a greenhouse

can feed at least 3-5 people on one acre of land.

Don’t think that this number is very low. If you follow the traditional

agricultural model, if you only plant rice on one mu of land, you can produce

five or six hundred catties of rice in one season and one thousand catties of

rice a year, which is all right. Reluctantly to meet the needs of two to three

people for rice.

But it is impossible for a person to eat only rice without eating vegetables

and other meats.

So in theory, if you want to feed a person and meet his dietary needs, one

acre of land with traditional planting methods is simply not enough.

But now this kind of ecological greenhouse can provide completely different.

First of all, the ecological greenhouse that can be used for three-dimensional

planting and ecological agricultural breeding can completely turn the original

acre of land into several acres of land~www.mtlnovel.com~ and greatly increase

the output of crops.

Not only that, the ecological system built in the ecological greenhouse can

produce a wide variety of fruits and vegetables, as well as eggs, milk and

meat obtained by raising poultry and livestock, as well as other agricultural

and sideline products.

A rich variety of food, especially the existence of meat, can greatly reduce

people's demand for a single food.

So in terms of how many people can be supported by one acre of land, of course

the ecological greenhouse will win.

However, correspondingly, the maintenance cost of the ecological greenhouse

has also been increased a lot.

In the traditional farming method, one person can do all the work on one mu of

land.

But for the ecological greenhouse, if there is no automatic machinery provided

by Chen Xin, and it is completely maintained by manpower, maybe three or five

people may not be able to maintain the operation of the ecological greenhouse

with an area of one acre, and these people must have enough knowledge to let

They can deal with all kinds of problems.

It’s just that although the investment cost is high, the ecological greenhouse

is also a huge piece of good news for the current situation in Yan Country.

Because for the current Yan country, the manpower needed to maintain an

ecological greenhouse is secondary, and more food output is the main thing.

After all, in the last days, manpower is very valuable, but food is very

valuable.

It is precisely because of this that the high level of Yan Guo pays special

attention to ecological greenhouses, and plans to adopt this model to build

new ecological greenhouses to produce more food.
