Are the vegetables and fruits produced by plant factories or fruit and vegetable factories really bad? Not necessarily.

At present, there are three channels of vegetables that we can eat, or three ways of production.

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

The second kind of fruit and vegetable production area, greenhouse centralized planting, commercial vegetables, through the fresh logistics channel sales throughout the country, 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, and cultivates vegetable products of consistent quality.

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

It's just our self-impression, it's not. This kind of vegetables grown by farmers themselves will be irrigated with farm fertilizer. What kind of farm fertilizer, chickens, ducks, pigs, cows or human manure is fermented and fertilized.

This way is no fertilizer pollution and is green enough. However, it is difficult to avoid contamination, especially the harmful bacteria and viruses contained in these farm fertilizers, which are very dangerous to human health.

If nothing else, let's talk about this E. coli infection, which is the most serious in rural areas.

Therefore, this kind of farmhouse dish can be eaten by small families, but it is not suitable for sale as a commodity, and the risk uncontrollable factor is very high.

The second is the greenhouse vegetables and commercial vegetables grown in the concentration of fruit and vegetable production. This kind of greenhouse vegetables is also the main body of vegetables we eat at present, but there are still many risks.

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

Therefore, the vegetables and fruits cultivated in this way look very good, very large, very round, very red, and of good quality. But in reality, the taste is very poor, and the residue of pesticides is heavy.

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

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

Vegetables, fruits and vegetables will be used as important materials in these special periods and become the target of competition in various regions. As a result, it is difficult to ensure the security of supply in areas that are not vegetable grown.

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 cultivation technology and controlled environment technology can greatly reduce the area used in the land. In a small area, the maximum benefits can be obtained through the three-dimensional planting technique.

Moreover, the controllable environment technology can control the production cycle and time of these plants as you like, and is not affected by the external weather and natural environment, so that it can be planted seamlessly throughout the year and the yield is huge.

In addition, because it is planted in a closed artificial environment, there are no pests and diseases, so there is no need to spray pesticides. And so the planting adopts hydroponic 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 you buy in the market is the same size of leaves, the thickness and length of cucumbers are the same, the roundness of pumpkins is the same, the size is the same, the tomatoes are as red, the sugar content is the same, and so on.

Of course, there are also disadvantages and disadvantages in the production of this plant factory, first of all, the construction cost of the plant factory is high, and the operation cost is high.

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 sides are different, for plant factories, as well as greenhouse vegetables, safety is the first, followed by quality.

The application of Wu Hao's technology can reduce the biggest cost in the production process of the plant factory, which is the labor cost. And through the intelligent management and control system, these vegetables and fruits can be controlled more accurately than people, so that their production efficiency is higher and the quality is more uniform.

Moreover, this kind of large-scale plant factory is generally located on the edge of the city, which is dependent on the city. In this way, the supply of vegetables and fruits in the city can be greatly guaranteed.

This form of fruit and vegetable planting and supply is also a very important part of the future social supply system, which will be directly related to the security of human food supply.

Especially in China, the urbanization rate is getting higher and higher, the number of people working on farms is gradually decreasing, and even with the death of the older generation, young people are reluctant to farm, which also makes domestic agricultural production will inevitably move towards the road of intelligent and unmanned.

If we do this well, then the food security of our people in our country may be affected.

The people regard food as the sky, which is the foundation of the country, so we must do this well.

This is also an important reason why Wu Hao and they were able to get support from top to bottom when they carried out this project.

It's farther than you can see, and it's deeper than you see.

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

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

As an enterprise, especially an enterprise with a sense of social responsibility and responsibility, since it has the ability and advantages in this regard, 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, which can basically cover the cost of research and development.

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

Moreover, the degree of intelligent autonomy is not enough, and there are times when 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 tackle 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 why Wu Hao said these 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 an opportunity to show the outside world their relevant development achievements in the past few years, especially in the field of public welfare.
