Was the first batch of seawater rice varieties born in my country?

According to reports, the "seawater rice" planted in Qingdao, Dongying and Daqing at the end of May has become green. It is reported that the Qingdao Seawater Rice R&D Center led by Yuan Longping has cultivated a strain with a yield of more than 600 kg per mu under the condition of 6 salinity irrigation water. Regional testing of varieties is currently underway.

According to the plan, the first batch of seawater rice varieties will be born in China in 2019, and it is expected that the rice varieties will be marketable in 2020.

At the end of May this year, 88-year-old Yuan Longping, an academician of the Chinese Academy of Engineering, gave on-site guidance to the National Coastal Saline-alkali Land Rice Improvement Demonstration Base in Chengyang District, Qingdao City.

According to Dr. Zhang Guodong, deputy director of the Qingdao Seawater Rice R&D Center, the varieties they breed can tolerate a salinity of 6, while the varieties selected by other breeders generally only tolerate a salinity of about 3.

Zhang Guodong's R&D center has cultivated a strain with a yield of more than 600 kilograms per mu under the condition of 6 salinity irrigation water, he said, "At present, regional tests of varieties are being carried out in major saline-alkali lands across the country, which will take two years, and then one year of productive experiments." In 2019, the first varieties of saline-alkali tolerant rice (i.e., seawater rice) will be born in China, and in 2020 they can be planted on a large scale. ”

For the future of seawater rice after the market, Zhang Guodong said that it will be at a level or slightly higher than ordinary rice, but not much higher, "the seed industry circulation market is a production materials market, not a high-profit industry, too high will affect the enthusiasm of farmers to buy."

According to Zhang Guodong, there is no national standard for the "seawater rice" variety, which is not recognized by the state, and in 2017, under their leadership, the relevant national standards have been formulated, and the varieties will be identified.

The discussion topic about our country's agricultural production has always been relatively intense, and one such news has triggered a wide discussion among countless netizens and friends, that is, the new rice of "seawater rice" is about to be put on the market. In response to the news that seawater rice is about to go on the market, many netizens and friends also raised some confusion in their hearts. For example, some netizens are very curious about the taste of this seawater rice?

What are the advantages of seawater rice?

In the face of the various questions raised by the majority of netizens and friends and the various confusions about our domestic seawater rice, I think it is necessary for us to understand some of the basic information we have learned. "Seawater rice, also known as saline-alkali tolerant rice, refers to a type of rice variety that can grow in saline-alkali land above salt concentration and yield of more than 300 kg and 667 m2. ”This kind of rice has a very tenacious vitality, can grow and develop very well in saline-alkali areas, not only that seawater rice has a very good insect resistance, which also further improves the yield of seawater rice.

1. Resistance to salinity

The biggest feature of seawater rice is that seawater rice has a very strong ability to resist salt and alkali, and this kind of salt and alkali resistant rice will also further increase our domestic grain production. Because we can grow more of this rice in the relevant saline-alkali areas, our domestic rice production area can be further increased. <>

Two: tenacious vitality

The vitality of seawater rice is very tenacious, which is not only reflected in the fact that this rice can survive in high salinity, but also because this rice has a very strong ability to resist insects. Therefore, the food yield that can be obtained by growing seawater rice in the relevant areas is very <>

It has stronger survivability, resistance to waterlogging and drought, lodging, resistance to diseases and insects than ordinary rice, and higher nutritional value.

The yield of this rice is very high, the steamed rice tastes very fragrant, the taste is very good, the rice grains are also very large, and the vitality is very tenacious.

The yield is very high, the survival competitiveness of this rice is very strong, this rice is particularly drought resistant, virus resistance is also very strong, this rice looks transparent, and the nutrients are also very high.

First of all, seawater rice definitely doesn't taste salty, and secondly, there are many varieties that also taste good. In addition, seawater rice has many unique advantages in terms of nutrition. First of all, from the perspective of quality, due to the high trace elements in saline-alkali land, the mineral content of seawater rice is higher than that of ordinary rice. Secondly, seawater rice grows in saline-alkali land with harsh conditions, rarely has diseases and pests, and basically does not need pesticides.

Many studies have also shown that moderate salinity conditions can promote the accumulation of secondary metabolites in plants.

First time I heard about seawater rice.

The name always makes people feel that it lives in seawater, but it is not. Seawater rice is a kind of rice that is between wild rice and cultivated rice, which is generally grown in seaside tidal flat areas and has salt and alkali toleranceSo, what is the difference between seawater rice and rice? <>

One, the appearance is different

The plants of seawater rice are somewhat taller than ordinary rice. After maturity, the ears of seawater rice can reach about 23 cm long for its paddy.

After threshing, the rice is carmine red. The plant height of ordinary rice is generally 1 meter high, of course, the height of ordinary rice is different for each variety. After the rice is threshed, the color of the rice is milky white.

Second, the characteristics are different

Seawater rice has different soils in which it growsFlood resistance, salinity-alkali resistance, and fall resistanceLodging, resistance to pests and diseases, etc. In these aspects, ordinary rice is a big difference, especially the characteristics of ordinary rice that are resistant to salinity and flooding. <>

Third, the taste is different

Rice made from seawater rice is not salty. Its softness is moderate, and the steamed rice looks crystal clear. In contrast, rice made from ordinary rice tastes average, and individuals prefer to eat rice made from seawater rice.

Fourth, the nutritional content is different

Due to the special cultivation measures of seawater rice, the rice produced from seawater rice contains as much protein as possible; And the rice made from ordinary rice is rich in protein. Seawater rice is rich in lipids.

Sodium is also higher than ordinary rice, and seawater rice also contains trace elements such as copper, iron, molybdenum, and manganese.

Fifth, the growth environment is different

Seawater rice mainly lives in the tidal flats of the sea, the corner of the sea, and the low-lying saline-alkali land.

After planting in May, it is completely free from fertilizing, insecticide, weeding, etc., but the tides are needed to "moisten" them. Whereas, ordinary rice is more suitable for growing in paddy fields with fresh water, and people need to fertilize, insecticide, and weed them on time.

Although seawater rice has great advantages, the main rice grown in China is still ordinary rice.

The taste and nutrients are different, the rice in the sea is more nutritious, the salt is also very high, and this rice can also be eaten with a good taste.

The difference between seawater rice and ordinary rice is that there will be some differences in the taste, and seawater rice has a little salty taste.

The planting site is different, the grain yield is completely different, the nutritional value is also completely different, and the ups and downs experienced in the planting process are also completely different.

The so-called "seawater rice" is said to be a wild rice plant found in the reeds by the sea in Suixi in the 80s of the last century. It is inferred from the fact that the reeds were able to form a large community here, and it is believed that it is not pure seawater, but a wetland formed by an inland river flowing into the sea, and its water is a mixture of freshwater and seawater.

The person in charge of the seawater rice project at Guangdong Ocean University said that its "Haihong 12" can be grown in soil with less salt content. The soil salinity of tidal flats, which are usually flooded by tidal water every day, should generally be consistent with the salinity of tidal water, so it is assumed that the so-called "seawater" salinity here should be 4 6 or less. This can also be confirmed by Academician Yuan Longping's claim that its "seawater rice" can tolerate a salt content below 6.

Seawater rice is a common name for saline-alkali tolerant rice, and traditional rice cannot grow normally on cultivated land containing certain salt and alkali components. The breeding experts of Qingdao Seawater Rice Research and Development Center have polymerized various genes such as salt tolerance, alkali tolerance, disease resistance, high quality and high yield through hybrid breeding technology and conventional breeding methods, combined with molecular marker-assisted selection, and selected and bred a new type of saline-alkali tolerant rice, which can be widely planted along the tidal flats, inland saline-alkali land and around saltwater lakes, which relieves the pressure on cultivated land and increases grain production and ensures national food security to a certain extent.

The invention of the inventor of seawater rice was robbed, which shows that Yuan Longping is a big **.

Speaking of seawater rice varieties, we have to mention"Sea Rice 86"It is a relatively precious germplasm resource of saline-alkali tolerant rice. It was learned from the Wuhan Institute of Seawater Rice Biotechnology that a new rice variety that can grow along the beach and saline-alkali land - "Haidao 86" has been successfully tested and promoted, with an average yield of more than 300 catties per mu.

Seawater rice is a rice grown in seawater along the beach, after more than 30 years of trial planting, "Haidao 86" has many characteristics such as good resistance to salinity, resistance and flooding, it will grow well in seawater below pH value, or salt content below 6 thousandths.

Seawater rice is saline-alkali tolerant rice, which refers to a type of rice variety that can grow in saline-alkali land with a salt (alkali) concentration above the vertical vertical and a yield of more than 300kg 667m2. At present, China has about 33 million acres of coastal mudflats of various natures, and once these tidal flats are utilized, it can at least feed tens of millions of people, and it can be said that seawater rice is too important for our and the world's food security.

1. Seawater rice is not actually rice grown in seawater. Its origin is on the seaside of Yanchao Village, Chengyue Town, Suixi County, and it is the land where the sea water has been soaked for a short time, so the growing place of this rice is saline-alkali land, and it is not afraid of the short-term soaking of sea water, so it is different from ordinary rice and is called seawater rice.

2. Planting seawater rice is not directly irrigated with seawater, but mixed with seawater and fresh water, and diluted to make brackish water before it can be used for irrigation, usually the seawater with salt content can be used as irrigation water for seawater rice, and the proportion of fresh water is 80-83%. Seawater rice has other names such as "salt-tolerant rice", which refers to rice varieties that can grow in saline-alkali land with a salt concentration of more than 300 kg per mu.

Food is the foundation of the country, "a grain of grain can bring down a country, but also can save a country" this is the words of Academician Yuan Lu infiltrated pants Longping, those older generations will remember how the lack of food felt, the reason why we don't feel much is because our grain production is increasing every year, the people will not worry about the basic food, and recently the new seawater rice is about to go on the market, will the yield of this rice be higher? The yield is only average compared to the current rice, but it has an advantage that other rice does not have, and it is specially adapted to saline-alkali land, which is a problem that all countries in the world have not overcome, and we have not only overcome it, but also achieved high yields and achieved more arable land use.

We have all heard a news before, "7% of the world's land, to feed 22% of the population", this is a miracle of modern times, all this credit is due to those scientists who pay silently, we can have a yield of thousands of catties of rice per mu, we know that a few decades ago the grain output was only more than 300 catties per mu, and there are many famine years, the output can not keep up with the growth of the population, resulting in many people starving to death, so the older generation often teaches us the importance of saving food, in this 7% of the arable land, There is still a large part of saline-alkali land, which is not suitable for the growth of ordinary rice at all, so scientists have conquered this area again, and now it is finally available, which will increase the food production of our country, at that time does not mean that we can have more waste, but know the importance of food, and the constant fact is that our food security has a major guarantee. <>

Although it is now an era of peace, there are still many places in the world that do not have enough to eat, and now we can see these things in the information age, so we must cherish these hard-won lives more and hope that this rice can shine and bring us better food production. <>

Probably, now rice is studied in different ways, and there will be different research techniques, so the yield will increase.

Yes, the yield will definitely get higher and higher, and you will get a very good cultivation that will allow people to eat very healthy food.

Yes, this rice will have a higher yield, this is a new type of rice, and there will definitely be a good yield.
