Welcome to the 20th National Congress | Hunan: Strengthen the high yield and regenerate rice

On July 1, the reporter learned from the Hunan Academy of Agricultural Sciences Hybrid Rice Research Center that the breeding team of the center has continued to organize the expert team to focus on the province's Luo Luo, Ningxiang, Xinhua, Anhua, Lianyuanyuan In other places, Shimoda guided the promotion of local regenerative rice demonstrations and focused on increasing the research on high -yield regenerative rice.

Regenerative rice has a small amount of medicinal fertilizer, and the cost -saving efficiency is obvious. It is the most economical and efficient planting model in the southern light and temperature resources of the southern light and temperature resources. Data show that the area of ​​regeneration rice in the southern rice areas in my country is about 84.6 million mu. As of now, the regenerative rice year's promotion area is about 16 million mu. Therefore, the potential for regenerating rice is huge.

In response to the new trend of hybrid rice development, Hunan Hybrid Rice Research Center has long adhered to regenerative rice innovation, and has accumulated many technologies and experiences in the cultivation of regenerative rice varieties and supporting technology research. As of now, the center has established a recycled rice cultivation and screening system to cultivate more than a dozen of rice varieties that are suitable for regeneration.

Since 2018, the "three -pointers to support one person" led by Yuan Longping, academician of the Chinese Academy of Engineering, has focused on regenerating rice research, including variety cultivation and planting models, etc. The seasonal yield is 800 kilograms, the regeneration season is 400 kg per mu, and the total output of 1200 kg in two seasons.

In this regard, the team existing in the existing production area and potential development zone in the "hybrid rice regeneration", paying attention to the yield, rice quality, pest resistance, high and low temperature tolerance, resistance, regeneration power of high and low temperature, regeneration, regeneration of regenerative rice varieties The coordination of comprehensive properties such as rolling resistance has improved, and strive to build a variety of supporting planting models that are suitable for annual production and more than a year.

This time, the research team arrived at the Mingyue Mountain Village Regenerative Rice Demonstration Base in Xianyue Mountain Village, Lishi Town, Hunan Province, and the Zhongtian Dragon Boat Agricultural Machinery Manufacturing Company and other places. Experts believe that the annual output of regeneration rice is high or not, and the first quarter is the key. The production in the first quarter is high or not. Management is the key. At present, it is urgent to strengthen the management of fertilizer and water in the middle and late stages of the first season, and the prevention and treatment of diseases and insects. At the same time, the team also discussed on how to screen a number of independent intellectual property rights, comprehensive traits, and suitable for regenerative rice varieties that are suitable for Hunan production, as well as how to increase the research of regenerative rice harvesting machinery. According to reports, the team plans to try 1 ~ 3 regenerative rice harvesting machinery in July to display the regenerative rice harvesting site and carry out large -scale regenerative rice demonstration services next year. In order to improve the level of regeneration rice cultivation in grass -roots agricultural technicians and large planting households, the center also actively carried out the training technology training of regenerative rice fields combining offline and offline.
