Latest website: At present, agricultural development has stagnated. Not only in terms of crop seeds, but also in the field of chemical fertilizers, or in the field of pesticides, it has basically reached a bottleneck period.

For example, in the field of chemical fertilizers and pesticides, our current research in the field of chemical fertilizers has basically stagnated. The effectiveness of chemical fertilizers has been maximized. It is currently difficult to develop new fertilizer formulas that can significantly increase crop yields.

The current research field on chemical fertilizers is mainly focused on technologies to improve fertilizer utilization, reduce environmental pollution, and increase crop yields.

The thinking of the entire industry, including the entire society, has also changed, and it has begun to pursue green environmental protection and sustainable development. For example, primitive fertilizers such as bio-organic fertilizers have begun to regain their youth.

As for the field of pesticides, the current development cannot be said to be stagnant, it can only be said to be very slow. Because people attach great importance to food safety, they are becoming more and more cautious about the application of pesticides on agricultural products. More and more agricultural products are beginning to focus on being ecologically pollution-free and pesticide-free, so this will also lead to some farmers becoming reluctant to use pesticides.

Of course, pesticides are essential in agricultural production and play a huge role in preventing pests and diseases. It’s just that the current pesticides have changed from the original goal of killing pests and diseases to have the characteristics of low toxins, low residues, no pollution, and decomposability.

Even now, some so-called biopesticides have begun to be developed, which are completely pollution-free, but they cannot be applied on a large scale.

Then there are the seeds of crops. In recent decades, crop seed technology has made great progress, from the original single selection method to the use of chemical soaking to increase the germination rate of seeds and improve the resistance of seeds to diseases and pests.

Then came the hybrid technology. It should be said that hybrid technology appeared very early. A long time ago, our ancestors learned to use hybridization between different crops to cultivate and domesticate better crop seeds.

Nowadays, hybrid technology is more advanced. After the application of new technologies, hybrid technology has a new lease of life.

Through crosses between different varieties, new genetic variations are created, from which offspring with excellent traits are selected for reproduction and breeding. The steps involved in this technology, such as parent selection, hybridization, selfing, and multi-generation selection, can be said to be an important part of modern seed technology.

Another example is the use of molecular marker technology to track and select target traits to improve the accuracy and efficiency of selection. For example, genes controlling important traits such as disease resistance, insect resistance, and drought resistance can be marked. Alternatively, professional tissues or cells can be used for in vitro culture to obtain asexual propagation lines or polyploid plants, from which haploid or diploid plants with excellent traits can be screened.

There is also haploid breeding technology, which uses methods such as haploid induction and doubling to obtain homozygous plants with excellent traits. The technical process of haploid breeding includes steps such as haploid induction, haploid identification and doubling.

Then there is the more controversial genetically modified technology, which can be used to introduce genes with excellent traits, such as insect resistance, disease resistance, drought tolerance, cold tolerance, herbicide resistance, etc., to make crops more adaptable to the environment and increase yield and quality. For example, genetically modified rapeseed can reduce the attack of pests and diseases and increase the yield and quality of rapeseed.

And we can also use genetically modified technology to breed new genetically modified crop varieties with efficient reproduction and high yields. These varieties can be reproduced and produced faster, thereby reducing the use of seeds and the need for agricultural labor, and reducing agricultural production costs. .

We can even use genetically modified technology to develop agricultural products with new traits, such as highly nutritious and high value-added products, thus increasing the added value of agricultural products. For example, genetically modified technology can increase the content of protein, oil and other nutrients in plants, providing people with higher quality food.

Finally, the rational use of genetically modified technology can also greatly reduce pollution and improve the agricultural ecological environment.

However, although genetically modified technology has been around for decades, it seems that except for us, the development of this technology has also stalled this year.

This may be because people and society generally have deep misunderstandings about genetically modified technology and genetically modified crops, which prevents this technology from being promoted on a large scale.

Speaking of this, Wu Hao paused for a moment, then waved his hands at everyone and said with a smile: "What I said so much is not to whitewash genetically modified technology.

It is true that genetically modified technology does have certain problems.

At present, its biggest problem is safety. Although many studies have proven the safety of genetically modified technology, there are still some problems because the development of this technology is still short.

For example, some genetically modified organisms may have stronger vitality and adaptability, thereby occupying a dominant position in the natural environment, squeezing the living space of other species, and even leading to the extinction of some species.

Another issue that people are more worried about is that the use of genetically modified technology may lead to genetic contamination. For example, mixing genetically modified corn with non-genetically modified corn may produce new offspring with unstable traits. This will not only destroy the stability of non-GMO corn traits, but may also have an impact on food safety and the ecological environment.

And this will also cause some ethical issues, such as whether it is in line with the laws of nature, whether it will cause harm to the ecological environment, etc. "

"Similarly, the advantages and disadvantages of gene editing technology and transgenic technology are actually similar, and they also face the same problems as transgenic technology."

At this point, Wu Hao emphasized: "But in my opinion, genetically modified technology and gene editing technology are the key to future agriculture and the development direction of future agriculture.

As the world's population continues to grow, so does the demand for food.

According to the United Nations, the world's population is expected to exceed 10 billion by the middle of this century, around 2059.

With such a huge population, the demand for food is undoubtedly huge and unprecedented. Who will feed these 10 billion people is also a problem faced by the whole world.

With the continuous increase of population, the continuous expansion of urban scale, and the continuous expansion of desertification and saline-alkali land, there is less and less land available for cultivation in the world.

Even now, nearly one billion people around the world are hungry. Global warming has led to endless natural disasters, and regional instability has led to an increasing number of people affected by disasters, and the number of hungry people is also increasing.

This is the case now, but when the population reaches 10 billion by the middle of this century, I don’t know how many people will go hungry. "
