The difference between sea rice and common rice
Sea rice (sea rice): It is a figurative name of salt-tolerant rice. Rice that can grow in saline-alkali land such as beaches (where seawater passes, not seawater) is not afraid of short-term immersion in seawater.
Misunderstanding: "Sea rice is rice that can grow in seawater". In fact, the salt content of seawater is 3.5%, and the early salt tolerance of sea rice is 0.5%. Yuan Longping participated in the Qingdao Sea Rice Research Project, and it is planned to improve the salt tolerance to no less than 1% in three years. On the basis of the existing naturally occurring wild rice with high salt tolerance and alkalinity, a rice variety which can be industrialized and popularized, grows normally under the seawater irrigation condition with salinity not lower than 1%, and the yield can reach 200-300 kg/mu. China has 200 million mu of saline-alkali land which can be used to grow sea rice. According to the future yield of 20-300 kilograms per mu, it can increase grain production by 50 billion kilograms and feed about 200 million people. Chen Risheng has been studying and popularizing in Zhanjiang for a long time, and Yuan Longping, the father of hybrid rice, participated in the research, which greatly improved the attention of related work. 201610/4. Yuan Longping presided over the Qingdao sea rice research project and set up a 30-mu sea rice research and breeding base with an initial capital of 6,543.8 billion yuan; 65438+February 10 Wuhan Institute of Sea Rice Biotechnology was established.
Growing habits:
After the high tide, sea rice will be submerged. The rice at the filling stage has blue and white ears, and the height is 1.7 meters ... In the experimental field of seawater rice planted by Hutoupo Professional Cooperative, golden yellow rice and blue and white stems and leaves are intertwined, and the ears covered with grains are bent down. Huang, a local villager, told us that sea rice can thrive as long as it absorbs nutrients from seawater, does not apply fertilizers and pesticides, and does not weed. The plant height of the most prosperous sea rice can reach more than 1.7 meters. At the same time, this sea rice also has the characteristics of wind resistance and waterlogging resistance. After many days of seawater intrusion caused by typhoons "rammasun" and "Seagull", it is still growing well, and there is hope for a bumper harvest at present.
