Are the vegetables and fruits produced by plant factories or fruit and vegetable factories really bad? uncertain.

At present, there are three channels for vegetables that we can eat, or three production methods.

The first type of smallholder production is that farmers grow their own crops and sell them at farmers' markets.

The second type of fruit and vegetable production area is concentrated cultivation in greenhouses, and commercial vegetables are sold all over the country through fresh logistics channels. This is also the supply channel for most of the vegetables we can eat.

The third type is this new type of agriculture, which uses plant factories for production, and is not affected by external factors to cultivate vegetable products of consistent quality.

These three production methods have their own advantages and disadvantages. First of all, the first type of smallholder production is the best vegetable in our impression, organic, green and pollution-free.

It's just our self-image, it's not. The vegetables grown by the farmers themselves will be irrigated with farmyard manure. What about farm manure? Chicken, duck, pig, cow or human manure is fertilized after fermentation.

This way there is no chemical fertilizer pollution and is sufficiently green. However, it is difficult to avoid contamination, especially the harmful bacteria and viruses contained in these farmyard manures, which are very dangerous to human health.

Don't say anything else, let's just talk about this E. coli infection, which is the most serious in rural areas.

Therefore, this kind of farm food can be eaten by small households, but it is not suitable for sale as a commodity, and the risk of uncontrollable factors is very high.

The second type refers to the greenhouse vegetables grown in concentrated fruit and vegetable production areas, commercial vegetables. This kind of greenhouse vegetables is also the main part of the vegetables we eat at present, but there are still many risks.

First of all, land pollution. In particular, some greenhouse vegetable growers constantly fertilize and spray pesticides in order to blindly pursue yield and quality.

So the vegetables and fruits cultivated in this way look very nice, big, round, very red, and of good quality. But in fact, the taste is very bad, and the residue of pesticide is very heavy.

The second is that it is easily affected by external factors, such as hail, floods, snowstorms, etc., so it is difficult to guarantee the output and quality.

Third, the distance between supply and demand is relatively long, and the security of supply and demand channels cannot be guaranteed. Once some special reasons or special disasters are encountered, these contradictions will appear.

Vegetables and fruits and vegetables will be used as important supplies during these special time periods and become the targets of competition in various regions.

As a result, it is difficult to ensure the security of supply in non-vegetable growing areas.

As for the third plant factory or fruit and vegetable factory, it is a new type of vegetable and fruit planting technology that has emerged in recent years.

The use of vertical planting technology and controlled environment technology can greatly reduce the use of land. In a small area, through three-dimensional planting technology, the greatest benefits can be obtained.

Moreover, the controllable environment technology can control the production cycle and time of these plants at will, without being affected by the external weather and natural environment, and can achieve seamless planting throughout the year with huge output.

In addition, because it is planted in a closed artificial environment, there are no pests and diseases, and naturally there is no need to spray pesticides. And all planting adopts hydroponics technology, which is safe and reliable.

All planting techniques are standardized, so that these vegetables and fruits can reach a uniform size.

For example, the lettuce leaves you buy in the market are all the same size, the cucumbers are the same thickness and length, the pumpkins are the same roundness and size, the tomatoes are the same red color, and the sugar content is the same, etc.

Of course, this kind of plant factory production also has shortcomings and shortcomings. First of all, the construction cost of the plant factory is high, and it requires high operating costs.

Secondly, the nutrition of vegetables and fruits produced by plant factories is indeed slightly worse than that of fruits and vegetables produced by farmers.

But the needs of both parties are different. For plant factories and greenhouse vegetables, safety comes first, followed by quality.

And Wu Hao's application of this technology can reduce the biggest cost in the production process of plant factories, which is labor costs. And through the intelligent control system, these vegetables and fruits can be controlled more precisely than humans, so that the production efficiency is higher and the quality is more uniform.

Moreover, such large-scale plant factories are generally located on the edge of the city, and are dependent on the city. In this way, the security of the supply of vegetables and fruits in the city can be greatly guaranteed.

And this form of fruit and vegetable planting and supply is also a very important part of the future social supply system, which will directly affect the safety of human food supply.

Especially in China, the urbanization rate is getting higher and higher, and the number of people working on farms is gradually decreasing. Even with the passing of the older generation, young people are not willing to work in farming. This also makes domestic agricultural production bound to become intelligent and infinite the road of humanity.

If this is done well, the food security of our domestic people may be affected.

Food is the most important thing for the people, which is the foundation of the country, so it must be done well.

This is also an important reason why Wu Hao and the others were able to get support from top to bottom when they were working on this project.

The upper part is farther and deeper than what you can see.

At present, this project has also been included in the key projects of the agricultural development department, and will be developed as a high-tech agricultural technology in the future.

This is also the reason why this project is popular everywhere. The ultra-large-scale farms in the Northeast can take the lead in extending olive branches and inviting them to carry out the construction project of intelligent unmanned farms.

As a company, especially a company with a sense of social responsibility and responsibility, since it has the ability and advantages in this area, it should assume this responsibility.

Moreover, the benefits brought to them by this project are also very considerable, especially the current construction of these projects can basically fill the research and development costs.

Of course, this is still just the beginning, and this system, or this technology, still has many imperfections.

Moreover, the degree of intelligence and autonomy is not enough, and sometimes human intervention is required. The second is that the cost is still relatively high, so it is more difficult to popularize.

In the next step, the scientific research team will overcome these problems one by one, so as to continue to work hard to bring our country's agricultural production into a new era of intelligent development.

The reason Wu Hao said this at the press conference is also to promote this technology as much as possible, eliminate everyone's prejudice and misunderstanding, and truly promote the development of this technology.

On the other hand, it is also to take this opportunity to show the outside world their relevant development achievements in the past few years, especially the fruitful achievements in public welfare.
