Yuan Lao's double-cropping rice yielded 1500 kilograms per mu
Realized in Hainan
The yield of late planting mu is 660.36 kg
Plus 926.5 kg of early manufacturing
Hainan double-season mu yield of 1586.86 kg
Set a record for the highest number of rice in the history of double seasons in Hainan

Quickly occupied the 6th place on the Weibo hot search list
Netizens have left messages in the topic to brush the screen
"Be grateful, cherish every grain"
"Grandpa Yuan, did you see it?"
"You are not there, but the dream is still there..."
"The yield of late planting mu is 660.36 kg, plus 926.5 kg of early cropping, and the yield of double-season mu is 1586.86 kg." Elder Yuan, your double-season yield of 1500 kilograms per mu, Hainan has come true! On the 26th, the rice wave rolled over the Nanfan Public Test Base in Yazhou District, Sanya, and Cao Bing, a researcher at the Sanya Nanfan Research Institute of Hainan University, who got the production measurement results, said excitedly. At this time, under the breeze, the rice stems that were bent by the full grain ears swayed with the wind, as if waving to Elder Yuan, and the whole rice field was like a blanket of golden light.
On October 26, the late production of Nanfan Public Experimental Base in Yazhou District, Sanya was 660.36 kg per mu, plus 926.5 kg of early manufacturing, and the yield of double-season mu reached 1586.86 kg, achieving the goal of 1500 kg per mu of academician Yuan Longping.

"It's a big breakthrough." Cao Bing said that the target of 1,500 kilograms of rice per mu in double-cropping has been achieved in Yunnan and Hunan. However, in Hainan, due to the short growth period and high temperature of rice, it is difficult for rice to yield high.
"It is not easy for Hainan to achieve the target of 1,500 kilograms per mu of rice in double cropping." Tu Shengbin, an associate researcher at the Chengdu Institute of Biology of the Chinese Academy of Sciences, who took over the conversation, thoughts back to 11 months ago.
"Double-season mu yield of 1500 kilograms" is the key goal proposed by Academician Yuan Longping to ensure national food security before his death. Under the initiative of Academician Yuan Longping, on December 20, 2020, the national hybrid rice double-cropping project of 1500 kg per mu was held in Sanya, and Yuan Lao personally served as the chief scientist of the project research leading group.
Subsequently, the Hainan Academy of Agricultural Sciences, Sanya Municipal Bureau of Agriculture and Rural Affairs, Sanya Nanfan Science and Technology Research Institute and other project implementation units overcame difficulties such as tight planting seasons and poor conditions, and organized 6 early demonstration sites in 5 cities and counties in Hainan.
Last winter and this spring, the low temperature and low-light climate in Hainan Province were unfavorable to early rice sowing, seedling growth and transplanting. However, the experts overcame the problems through regulatory techniques such as wide and narrow row planting, nitrogen control and upside down resistance cultivation, and anti-aging seed cultivation, laying a good technical foundation for the success of the project.
The average yield is 926.5 kg per mu. The production test results of the Nanfan Public Test Base in Yazhou District, Sanya on May 14 mean that the late manufacturing test only needs nearly 600 kilograms to achieve the target.
In the late manufacturing test, after many repeated demonstrations, it was determined that the site was selected in 10 test demonstration sites in 9 cities and counties such as Haikou, Sanya, Dongfang, Wuzhishan, Changjiang, Lingshui, Ding'an, Lingao and Ledong.
Selecting plots, harvesting, measuring moisture... On October 26, at the Nanfan Public Experimental Base in Yazhou District, Sanya, experts randomly selected 3 plots to measure production. The average yield per mu was 660.36 kg, and the average yield of early cropping was 926.5 kg per mu, and the yield of double-cropping mu reached 1586.86 kg, setting a record for the double-season history of rice in Hainan.
"This can comfort Old Yuan!" Tu Shengbin said that Before his death, Yuan Lao had been worried about the progress of the 1500 kg project in Hainan's double-season mu. In March, during the 2021 China Seed Conference and the Nanfan Silicon Valley Forum in Sanya, Yuan Lao, who was hospitalized at the time, asked his assistant to go to the test site to see and then tell him about the growth of rice.
"Although Elder Yuan has not personally seen the realization of the goal of tackling the problem, I believe that he will have a perception under the Nine Springs." Cao Bing clearly remembers that in May, when he transmitted the production data of two test sites in Sanya to Elder Yuan through pictures and videos, Elder Yuan in the ward was particularly happy.
"The same is to achieve the double-season yield of 1500 kilograms per mu, Hainan is of greater significance than Hunan, Yunnan and other places." Hainan's climate is similar to that of Southeast Asian countries, and achieving the goal will promote international cooperation and lead Hainan rice into countries along the 'Belt and Road'." Tu Shengbin said.
The results are not easy to come by!
We remember Elder Yuan and remember the entrustment
Hold the rice bowl firmly in your hands
