The sea rice we are talking about now is actually salt-tolerant hybrid rice. First of all, it is not a new species, it has existed before. Moreover, both China and other countries have extensive saline-alkali land, but the sea rice in those places has the defects of low yield and poor rice quality. Therefore, Yuan Longping team hopes to make full use of saline-alkali land through the research, development and popularization of sea rice, so as to increase food production and benefit mankind.
Ordinary rice will definitely use a lot of chemical fertilizers in the process of planting, and chemical fertilizers contain a heavy metal called cadmium. If this heavy metal reaches a certain amount, it will cause great harm to human body, and the accumulation of cadmium pollution by different varieties of rice is different. In general, super rice has the strongest ability to transport cadmium to grains, followed by hybrid rice and conventional rice.
At present, the technologies for removing cadmium from rice developed and applied in the world mainly include soil improvement, cadmium rice adsorption and irradiation breeding. The method that Yuan Longping's team thought of was to modify the cadmium-absorbing gene in rice so that it would not absorb cadmium during its growth. This technical breakthrough has achieved a difficult breakthrough from full to safe and assured eating.
There is no doubt that Yuan Longping's team's research and development of sea rice is of great significance. Otherwise, netizens will not joke that "only Grandpa Yuan Longping can call me fat".
