The record of average yield per mu of rice in China is getting lower and lower.

A few days ago, the Ministry of Agriculture announced that the experimental plot known to Academician Yuan Longping had a yield of 926 kg per mu, setting a Chinese record. However, a commentator named "Barry" searched the data and found that as early as before, in addition to the satellite with a yield of 100,000 jin per mu released by People's Daily in the 1958's, Xinhua News Agency released news in 2006 that the yield of rice per mu was 1287 kilograms. Yunnan Daily released news in 2010, saying that the yield of rice per mu exceeded 1000 kilograms. If Academician Yuan's 926 kg is a record, is it true that China's record is getting lower and lower? After Academician Yuan's "record" was released, Chen Jieren questioned that the yield measurement of the Ministry of Agriculture was not open and transparent and was besieged by a large group of people for two main reasons: first, are non-agronomists qualified to question agronomists? Second, Academician Yuan is a famous scientist, and the output is determined by the state. I will not refute these reasons. I just want to ask you to look at these pictures and ask again: is there really no need to question? If non-agricultural personnel cannot question the agricultural sector, will it be impossible for people who do not work in the detention center to question the day someone dies in the detention center?

Hunan Daily-how does Yuan Longping set a new record?

On the afternoon of 19 September, an expert group of the Ministry of Agriculture announced in Changsha: the super hybrid rice tackled by Academician Yuan Longping has an average yield of 926.6 kg per mu in Yangguao Township, Longhui County, Shaoyang City, Hunan Province. Some media said that this is a record of super high yield of rice that shocked the world.

The amazing news spread all over the country the next day, and a village secretary as far away as the northeast said to me unconvincingly: our village could have reached a yield of more than 900 kilograms per mu more than a decade ago. Listening to his tone is very firm, I doubtfully looked it up on the Internet, who knows, the doubt is even bigger.

First, I found a report by Xinhua News Agency on September 7, 2006: "1287 kg: China sets a new record for rice yield per mu in the world" (the original title is so, readers can ask for it according to the title). The latest record for the world's rice yield per mu was born on the same day in Taoyuan Township, Yongsheng County, Yunnan Province, the report said: the new rice variety "Xieyou 107" achieved a real yield of 1287 kg per mu through accurate quantitative cultivation techniques. The report said that this is the Ministry of Science and Technology organized experts on-site acceptance. According to reports, "Xieyou 107" is a new super hybrid rice variety selected by a research group headed by Professor Wan Jianmin, a "Yangtze River Scholar", with the support of the national "863" special funds and approved by the state.

A very smart friend did not agree that this is "accurate quantitative cultivation", others are "100 mu average yield", there is no comparability. Is that really the case? I accidentally found the front page of Yunnan Daily on September 22, 2010: "Chujing 28 sets a new world record for rice yield per mu and the average yield per mu of 100 mu demonstration fields exceeds 1000 kg." the report said that the super rice variety "Chujing 28", bred by Li Kaibin, a rice breeding expert from the Agricultural Science extension Research Institute of Chuxiong Yi Autonomous Prefecture in Yunnan Province, was popularized and planted on a large scale in Touyi Village, Yinjie Town, Midu County. The expert group entrusted by the Science and Education Department of the Yunnan Provincial Agriculture Department has checked and accepted that the average yield per mu of its 100 mu has reached 1002.11 kg, setting a new world record of 988.77 kg per mu.
