Sea rice, why can it be planted in seawater and other crops can't?

Hymie may be misunderstood as related to seawater, but it actually reflects salinity more accurately. Sea rice in China has not been planted in a large area, but it is in the stage of hybridization experiment, which is expected to obtain high yield. For this purpose, Qingdao Haimi R&D Center (led by Yuan Lao) was specially established, and a large number of test sites were opened. However, under different salinities, the yield of dried seaweed is different. For example, in the current testing environment, the salinity is 0.6%.

Qaidam basin belongs to the plateau continental climate, which is much drier than the coastal areas of China, and the temperature drops greatly. In addition, there are natural salt lakes in the basin, which is an excellent experimental environment. Once the dry seaweed experiment here is successful, large-scale production can be realized, which means that the dry seaweed varieties with drought tolerance and cold tolerance are successfully cultivated. By then, the whole northwest region and the surrounding areas of Qinghai Lake can be planted in a large area, and the grain output of China will be comprehensively improved again.

Different from ordinary rice, saline-alkali tolerant rice is a kind of rice between wild rice and cultivated rice, which generally grows in tidal flat areas. China's coastline is tortuous, and the coastal beach area is vast. The low-lying and flat terrain here has become the mouth of many rivers. Irrigation conditions are very convenient, especially suitable for rice planting.

However, there are also some shortcomings, such as high salinity in coastal beaches, so it is necessary to cultivate new varieties and actively adapt to this new environment. Our country has made a lot of efforts to this end. Liaoning began to study saline-alkali tolerant rice, and China Academy of Agricultural Sciences and other institutions also introduced a considerable number of saline-alkali tolerant rice materials from abroad for screening. Known as the "father of hybrid rice", the team of Qingdao Haimi R&D Center led by Yuan Longping, an academician of China Academy of Engineering, successfully measured the yield of Haimi in Qingdao.

The Qaidam Basin is located in the Qinghai-Tibet Plateau, with special climatic conditions, flat terrain and serious land salinization, which is similar to some salinized areas along the northern coast of China. If the trial planting of seaweed in this area is successful, the boundless land will become fertile land. Undoubtedly, it will expand the cultivated land area in China and increase the grain output. Keep the rice bowl firmly in your own hands, ensure food security and improve the living environment. It is a great pioneering work that benefits the present and the future, thus subverting people's cognition. Planting spoiled rice in the salty desert will have a far-reaching impact on the world, so that those countries that have long relied on food imports can get rid of the passive situation and achieve self-sufficiency. It is an outstanding contribution to human society.

People think that dried seaweed grows in seawater, but this is not the case. So far, rice can't grow in seawater. Basically, plants living on land can't directly irrigate seawater, because the salinity of seawater is too high, and plants growing on land are used to fresh water environment and basically can't survive in seawater. The reason why it is called seawater channel is because this kind of rice has high saline-alkali tolerance and can survive in saline-alkali land by the sea, so it is named! Its scientific name is actually salt-tolerant rice.
