China's northernst coast 6 sacry-resistant "sea rice" test species success

Recently, Yuan Longping
and his research team "double-season super rice production broke the world record" news cheered the people of China, November 4, in China's northern Liaoning Panjin, another good news: Yuan Longping
and his research team 6 salt-resistant rice screening and cultivation achieved initial success, an average yield of more than 300 kg per acre, which means that "sea rice" in the vast salt-alkali land in northern China has the initial significance and value of promotion.
harvested this fall, planted for decades and irrigated with salt water for the first time. "Yang Jun Chong, 64, is a plumber in the experimental field, busy all year, Yang Jun Chong is still full of excitement." The average rice is , but this new variety has nothing to do. Yang Junzong gently stroked the golden rice grains in glassware with his hand, as if they were a golden bean. On November 3rd, at Panjin Test Station, the National Salt-resistant Alkaline Rice Innovation Center located in Panjin High-tech Industrial Development Zone, the reporter met the legendary "sea rice". "Sea rice", the name of salt-resistant rice, refers to rice that can grow on a salt-alkali soil at a certain salt (alkali) degree. It is adaptable, not only resistant to saline, but also resistant to wind, waterlogging, pests and diseases.
Panjin is located between 40 and 42 degrees north latitude, across China's northernst coastline, located in the mouth of the Liao River, there is a large area of saline resources. In this screening, test planting of high-salt-alkali varieties "sea rice", will be in the Northeast high-salt-alkali land rice cultivation and utilization to explore a new way. In 2019, Yuan Longping
team and the National Hybrid Rice Engineering and Technology Center created the "National Salt-resistant Alkaline Rice Test demonstration base", Yuan Longping personally named the "Northern Salt-Lyne Rice Yuan Longping
working test station" settled in Panjin, China's northernst coastline this retreat has a new historical mission.
Yang Jun Chong said that although Panjin is also growing rice on saline soil, but the vast majority of the planting areas have been improved, the salt content in the soil and water has been less than 1 per thousand, the general rice species can not grow in the high-salt soil environment. The test base screened 209 salt-alkali rice varieties, 100 high-quality rice varieties and 12 high-quality rice varieties in the region for breeding.
test field selected 130 acres of land located at the mouth of the LiaoHe River, but the sea water introduced under natural conditions is still not enough for the cultivation of 6 salphate-resistant rice. The test station introduced intelligent equipment and drilled a deep well with a salt content of 22.4 inches near the test field. To ensure that the salt water dilution concentration reached 6 inches and then irrigation, to ensure the success of screening, breeding tests.
this year is the first year of breeding, after unremitting efforts, has been initially screened out of salt-resistant alkali and high-quality rice varieties more than 30 copies, of which the most difficult scientific research 6 salt-resistant rice varieties 6. With Yuan Longping
team cooperation of Liaoning Zhongju Eco-Agricultural Science and Technology Development Co., Ltd. Chairman Zhang Sub said that salt-resistant rice and ordinary rice in the appearance of similar, rice spike on the number of grains less than ordinary rice;
"There are also river crabs," Zhang said, this year's salt water rice crab combined test, the results are gratifying. Not only is "sea rice" growing vigorously, but the taste of crabs is more delicious than that of ordinary rice paddies, which greatly increases the added value of the yield of high-salt-alkali rice per acre. In the future to promote planting, can achieve the current season "crab" has benefits, that year "rice" has benefits, this is panjin test planting "sea rice" produced by the new harvest.
to the reporter calculated an account: this year' 6 salt water irrigation rice paddies yield 400 kg of rice, 25 kg of farmed river crabs, only these two income can reach about 2200 yuan. Salt-resistant rice straw salt content is very high, Inner Mongolia farmers
on the straw more than 30 indicators of laboratory analysis, found that salty straw is stronger than high-quality pasture, is a good green feed additives. Compared with ordinary farmland, the amount of salt-resistant rice was reduced by 60%, the pesticide residue of rice was significantly lower than that of ordinary rice, and the quality of rice was also significantly improved.
", "the beach is painted as a good field, salt-alkali land in the rice flower fragrance", is Yuan Longping
and his team made a vow. "Next year, we will do further tests in the rice species irrigated by
8 inches of salt water, " said Peng Yulin, a team expert and deputy director of the scientific research department of the National Hybrid Rice Center. " With
soil improvement and the progress of planting technology, the yield of "sea rice" will increase year by year, and the previously worthless saline land will become a sought-after "scent". Yuan Longping said
,500 million mu of barren saline land in China, of which 200 million mu have the potential to grow rice. After the successful trial and promotion, according to the output value of 200 to 300 kg per acre, can increase grain production by 50 billion kg, more than 200 million people. ”
