The first is to be cautious when introducing species that reproduce and produce ultra-fast, the second is to be cautious when introducing carnivorous species, and the third is to cause an uproar in the venue when it was said at the science and technology conference, that is, all those with edible value or excellent feed, as long as they do not bring malignant diseases that are not available in the country, they can be safely and boldly introduced, there are 700 million mouths in China, they can not pose a threat at all, and Hu Weidong called China a "big foodie empire" The nickname also spread throughout China and even the whole Shijie, and some foreigners ridiculed that "Chinese will eat everything they can eat, and call what is difficult to swallow medicine." "It has become a daxiao material after tea and dinner for Chinese

At the beginning, many people thought that the name "foodie" was impliedly derogatory, but Hu Weidong did not think so, and he cited countless examples in history to prove that it is the delicious taste of the Chinese that has benefited shijie, and "foodie" is not a derogatory term, but a symbol of the tenacious vitality of the Chinese nation

When foreigners only felt disgusted when they saw the caterpillar spinning silk and forming cocoons, we invented bright silk; When foreigners felt that it was enough to burn pottery, we changed the temperature of the fire and the soil to make fine porcelain; When foreigners discarded the bitter taste of ginger, we learned that this thing could replace expensive spices to eliminate the fishy smell; When foreigners are helpless in the face of all kinds of animals and plants that are difficult to swallow, we can turn them into delicious dishes through the "magic of fire"; When foreigners stay away from all kinds of poisons, our ancestors have long known what it means to fight poison with poison; When foreigners feel troublesome and throw feces everywhere. The Chinese collect these filthy things and turn them into treasures; It is precisely because of such industrious and intelligent Chinese ancestors that the only great civilization on Shijie that continues to this day can be created

The reason why Hu Weidong brought up the topic of eating at such an important science and technology conference is mainly because he is deeply worried about China's future food ration problem, China's population is growing too fast, and considering the huge side effects of the one-child system, even after the end of World War II, Hu Weidong does not plan to engage in the one-child system to step on the sudden brakes of population growth.

However, the effect of the two-child system will inevitably be much slower, so the future food pressure will inevitably be greater than in history, and the potential of chemical fertilizers, pesticides and water conservancy construction to increase production has been relatively limited, and the rapid growth of agricultural production in the past few years is coming to an end. In the case that it is difficult to increase the area of cultivated land significantly. The only hope is seeds, and whether it is a new, high-yielding crop or a high-yielding improved variety of existing crops, China desperately needs.

The discovery and domestication of new species takes time. And Hu Weidong also doesn't remember that in later generations, important new crops were discovered that changed shijie. Therefore, the focus is always on the internal exploitation of existing crops. In addition to radiation breeding, which theoretically has unlimited potential. Hu Weidong also asked Tong Dizhou and other top biologists in China to start sequencing the genes of major crops such as rice to lay the foundation for future research on genetically modified organisms. However, it is very labor-intensive and time-consuming, so the sooner it is started, the better.

Although Hu Weidong is not a biologist, the matter of GMO before crossing has caused a lot of uproar in China, so he has also used his leisure time to learn some information. In Hu Weidong's view, it doesn't matter whether the GM itself is good or bad, the key depends on how you do it, and the specific situation of China's agriculture is very different from that of the West, so it is impossible to simply follow the research route of others.

For example, Western agriculture, especially the agriculture of the United States, is a large-scale and highly mechanized model, so their genetically modified focus is on improving the ability of crops to resist insects and diseases, because the relative lack of disaster resistance is precisely the biggest weakness of mechanized agriculture, so they even introduce some animal genes into the genes of crops. This is undoubtedly very unsafe, but it is not too much of a problem for Westerners, because most of the crops they grow are used for livestock feed or oil extraction and other industrial purposes, and are rarely eaten directly, so the safety requirements can be relatively relaxed, but most of China's crops are directly used to fill their stomachs, and the safety requirements must be higher.

For example, the United States allows the addition of clenbuterol to pig feed, because there is not much clenbuterol residue in pork, and Americans do not eat animal offal that is easy to accumulate with clenbuterol, so the problem is not very big, but in China. If it is also allowed to add clenbuterol to pig feed, it must be a big problem, because Chinese eat animal offal

Moreover, China's agricultural manpower is sufficient, and the ability to resist disasters and provide disaster relief (disaster prevention aside) is much stronger than that of the vast and sparsely populated United States, and the pressure of eating is much greater than that of the United States, so the insect resistance and disaster resistance of Chinese crops is far less important than the yield, and it is obvious that the genes of animals will hardly help the latter, and the introduction of genes of high-yielding plants is the right idea, for example, the later academician Yuan Longping proposed that the genes of C4 plants with higher photosynthesis efficiency can be introduced into rice with lower photosynthesis efficiency. C3 plants such as wheat, if successful, can increase the yield by at least several percent, its value is far greater than the improvement of insect and disease resistance, and the introduction of plant genes, the safety is far better than the introduction of animal genes, even even if the same plant genes, the genes that increase crop yield are still much safer than insect resistance genes, which is the right way for the development of genetically modified science in China

Of course, it takes a long time to complete the sequencing of the gene maps of major crops, so the main ways of breeding in China are the rapidly developing radiation breeding and more traditional hybrid breeding. Due to the beginning of the "911 Project", China's radiation breeding research has developed rapidly, compared with the more traditional and backward hybrid breeding inevitably looked down upon, Hu Weidong had to re-emphasize his long-standing view, "For the application of science and technology, not advanced must be the most haode, make full use of the mature jishu, often has greater practical significance." ”

To Hu Weidong's delight, the "wild defeat" (i.e., pollen abortion of wild rice) required by Yuan Longping scientists to cultivate the most critical "sterile line" of three-line hybrid rice has been found in Hainan Island, which has cleared the way for the successful breeding of three-line hybrid rice in the future, and the discoverer has also won the first prize of national science and technology (each conference has a special prize, two first prizes, four second prizes, and eight third prizes, of which the special prize is vacant most of the time because of the extremely high standard.
