Original title: The double season hybrid rice yield per mu reached 1530.76 kg, exceeding the expected target
According to the news from CCTV news client, yesterday, in Hengnan County, Hengyang City, Hunan Province, Yuan Longping led a dual season hybrid rice yield of 1530.76 kg per mu, including 619.06 kg of early rice and the third generation late hybrid rice variety. “Sanyou One” 911.7 kg, exceeding the expected target of 1,500 kg.
More than 30 acres of rice fields, seen from the air, are high in the east and low in the west, they are of different sizes, arranged in a trapezoid shape, surrounded by many hills. This is the birthplace of the third generation double season hybrid rice.
Where is the “super” of the third generation double season hybrid rice?
First of all, from the appearance point of view, the third generation double crop hybrid rice is robust, totaling more than 600 rice ears, which is three times more than ordinary rice ears. By increasing the number of particles and increasing production, this is the first “super” created by the scientific research team of Academician Yuan Longping.
Second, under the microscope, compared with ordinary rice, when the length is basically the same, the third-generation double-crop hybrid rice has more “fatty” rice grains. It is the length of southern indica rice and the width of northern japonica rice. Planting rice has all the advantages.
It is not easy for third generation double season hybrid rice to achieve such results.
One of the difficulties is the weather. September is the key period for heading and filling of late rice, but in September this year, Hengnan County had more rain and less sunlight. This field is also in 2019, with more than 260 hours of sunshine in September, and only more than 40 hours this year.
The successful production test is a new breakthrough in the eyes of academic Yuan Longping. “The average yield per mu of third-generation double crop hybrid rice is 10-20% higher than existing high-yield hybrid rice, which means an increase of more than 100 kg. There are 250 million mu of hybrid rice in our country. If the yield per mu is increased by 100 kg It can increase production by tens of billions of kilograms and increase food production to half of Hunan province. “
■ Dialogue
Yuan Longping: Very satisfied with the results of the production tests.
According to the news from the CCTV news client, yesterday, the academic Yuan Longping, who is in his nineties, saw the hybrid rice production test site through a video at the National Engineering Technology Research Center of Hybrid Rice in Changsha, Hunan. Hearing the results of the production test, Academician Yuan Longping said: very satisfied.
Academician Yuan Longping: 911 (kg / mu) right?
Reporter: 911.7 (kg / mu).
Scholar Yuan Longping: Good.
Academician Yuan Longping: 911.7 (kg / mu) right?
Journalist: Are the numbers particularly good? How do you feel now?
Scholar Yuan Longping: Very excited, even more excited. I was very satisfied when it could reach 880 kg (per mu), but now it exceeds 900 kg (per mu), so I am very satisfied. This is the result of everyone’s joint effort. (Double season rice yield per mu) 3000 jin, made in Hunan, the hometown of hybrid rice, is even more icing on the cake, I am very satisfied.
Reporter: What is your next goal?
Scholar Yuan Longping: The next step is to promote Hengnan’s experience in the province and rice-producing areas of the country, and make further contributions to national food security.
