Yesterday, Academician Yuan Longping was looking at the growth of super hybrid rice planted by the farmer Wang Xianmei. On the same day, the third phase of the research project for super hybrid rice and the “three kinds of four†high-yield project will reveal that a breakthrough has been made in the high-yield research of super hybrid rice, and the target of producing 900 kg per mu is expected to be realized next month.

The newspaper Longhui News (Reporter Li Du correspondent Xin Yejun) made a major breakthrough in the high-yield research of super hybrid rice, and the target of producing 900 kilograms per month is expected to be realized next month! Yesterday, a group of famous domestic rice experts gathered in Yanggu Township, Longhui County, Shaoyang County. Niuzuzai Village, a 102-mu experimental plot, has been field-tested by experts. The results show that the yield per mu in the 100-mu paddy field is expected to exceed 900 kg.
Although the super hybrid rice led by academician Yuan Longping led a historical record of over 1,200 kilograms in small areas in Yunnan and other places, in Hunan, a major area of ​​rice production, a large-scale demonstration planted part of Qiu Block and produced 900 kilograms of spurt. first. This means that China's super hybrid rice harvesting a large area of ​​900 kilograms per kilogram of the third-level difficulties has now dawned.
The hybrid rice has a large area of ​​900 kilograms per mu. This is the highest peak in the world history of hybrid rice so far, and it is also a new leap from Yuan Longping, the father of hybrid rice, to the Chinese experts on the world grain issue. It is understood that at present, the three hundred acres of experimental bases established for scientific research and development are located in Hunan, which are located in Shaoyang Longhui, Luzhou Fucheng and Huaihua Zhapu respectively. Judging from the current situation of rice growth and maturity, the Longhui demonstration project is expected to be the first to sprint at the target point.
There are still some days when the middle rice is harvested. How to ensure science in the production test? Experts told reporters that the main basis for measuring production is the number of grains per panicle and plumpness. Luo Xiaohe, a breeding expert, demonstrated to a reporter at a test field in Niuzhuangzui Village, Yanggu Township, Longhui. He handed over one hand and counted more than 300 stones. There were also more than 200 grains for “sparse†spots. , And rice ears are full. Luo Xiaohe told reporters that according to estimates, if only 200 grains per mu can be achieved, the yield per mu can reach 900 kilograms per mu, and the yield per mu can reach 1,000 kilograms in front of an experimental field.
It is understood that the super hybrid rice has been approaching the target of breaking a large area of ​​900 kg per mu last year. Qing Xianguo, a well-known rice expert and chief scientist of Hunan's grain production project, said that the task force built a base test in Niuzhuangzui Village last year and accepted two blocks, with a yield of 838.8 kg and 891 kg respectively.
Seeing that the super hybrid rice finally leaped to a yield of 900 kilograms per mu in the demonstration area, Yuan Longping smiled exceptionally brilliantly. He told reporters that this year, a group of super-high-yielding potential seedling combinations developed by the member units of the Provincial Super Rice Collaborative Unit will exert their full force. Among them, Y58S/Xianghui 3218, Shuang 8S/0293, Yyou 7, P88S/747, Y Liangyou 302 showed particularly eye-catching performance, coupled with the maturing super-high yield cultivation techniques. The super hybrid rice was produced in part of the mound. After reaching 900 kilograms, there is hope that from the point to the face, the third target will be sprinted.

The preliminary success of the "Three-Four-Four-Four" high-yield project for super hybrid rice
The newspaper Longsheng News (Reporter Li Du correspondent Xin Yejun) was informed by the reporter from Yuan Longping, academician Yuan Longping, at the on-site conference on the third phase of the research project for the super hybrid rice and the “three kinds of four production†high yield project held in Longhui on the 21st. In 2007, the successful implementation of the super hybrid rice “three-produce four†high-yield project achieved initial success this year: the first batch of 20 model counties in our province this year, and seven model counties that selected super early rice have all been harvested. At least 33% of the targeted increase in yield; super hybrid rice, late rice is also expected to harvest.
As early as the end of 2006, in response to the grim situation in China and the significant progress made in the development of super hybrid rice, Academician Yuan Longping proposed the use of the technical achievements of super hybrid rice to produce 4 mu of land with 3 mu of land and greatly increase the The existing rice yields and total production, improve the economic benefits of farmers to grow grain, ensure the "three kinds of four" high-yield project of national food security. Through the joint implementation of the Provincial Department of Agriculture and the Hunan Hybrid Rice Research Center, the first batch of 20 model counties in Hengnan, Liuyang, and Longhui of our province took the lead to taste a bumper harvest last year, of which demonstration farms in 18 counties increased their yield by 33%.
It is reported that Hunan's "three-four-producing" model county will be expanded to 40 next year, and the area will be expanded from 60,000 mu to 240,000 mu. In addition, major grain counties in provinces such as Anhui, Sichuan and Henan provinces have applied for a new round of “three kinds of four†demonstrations.
