new society Sanya reporter Wang Xiaobin
"I am now under a great pressure, there are two things to do." On the 14 day, Yuan Longping, an academician of the Chinese Academy of engineering at the age of 88, was interviewed by reporters in Sanya, revealing that he had already arrived at his age, but still felt a great responsibility on his shoulders.
is Yuan Longping's speech at the conference. Hu Yaojie, who was born in 1930 by China News Service reporter,
"the first thing to do is to make large scale demonstration of hybrid rice and yield 1200 kilograms per mu." In the long distance race to improve rice yield, Yuan Longping and his team have not slackened. Yuan Longping, the old man with a healthy body and quick thinking, wants to achieve this goal before he becomes a "90's".
rice is the key to achieve high yield, high quality and multiple resistance. Yuan Longping revealed that his team had at least five months a year to breed new varieties of hybrid rice in Hainan. "Hainan is the golden treasure of the south. Generally, it takes eight generations to produce a variety, and eight generations a year. But in Sanya, the superior light and light resources can be planted in winter, so that eight generations can be completed in three years.
after the Chinese people's food and clothing problem was settled, Yuan Longping team joined the new goal in "long-distance race". "The direction of R & D of hybrid rice has been strategically adjusted, from the simple pursuit of high yield in the past to high yield and good quality." But Yuan Longping emphasized that quality should not be sacrificed at the expense of output.
mention super hybrid rice. Yuan Longping can't help boasting. "My super rice is so beautiful that everyone should go and have a look." Yuan Longping invited everyone to visit the rice field. "My super rice is the guard of honor in rice."
"the second thing is salt tolerant rice cultivation." Yuan Longping introduced the important progress in the cultivation of seawater rice in 2017. "Under the condition of 0.6% sea water concentration, a small area of production reached 620 kg per mu."
China has an area of 1 billion 500 million acres of saline alkali land in northwest, northeast, North China and coastal areas, of which 2 to 300 million mu has the potential to be improved into farmland. Yuan Longping envisaged the extension of one hundred million mu of sea rice. "The output per mu of 300 kg per mu will increase by 30 billion kilograms per year, which is equivalent to the total annual grain output of Hunan province." It can feed 80 million more people. "
it is understood that in 1986, Chen Risheng, the father of the "sea rice rice", found the wild rice which could resist the salt alkaline of the sea water, and began the cultivation of the sea rice, and obtained the valuable resources of "sea rice 86". Since 2016, the Yuan Longping team has begun to study the sea water hybrid rice, in the simple desalination of the seawater irrigated paddy field to carry out the experiment. In 2017, the results were achieved. The maximum yield of the small area was 620 kg per mu. At present, a number of sea water rice materials have been screened at the southern breeding base in Hainan, and a certain amount of seeds has been produced. The two goals of
"super hybrid rice yield 1200 kg per mu per mu and the success of the research and development of sea water hybrid rice are the direction of my team's current efforts." Yuan Longping hopes to be able to achieve it in 2020, when he is "satisfied enough to retire."
