Rice Experts Successfully Breed Super Northeast Rice to Realize Two-season Planting

Zhou Xiaodong, chief scientist of the National Institute of Agriculture’s Ministry of Agriculture on the efficient integration and utilization of local varieties and foreign resources, disclosed in an interview with reporters in Shenyang on the 5th that his more than ten years of scientific experiments found that through successful breeding methods, the breeding period was successfully selected. For the 80-day super-early-ripening rice, the double-season rice planting in Liaoning has been successfully achieved in the laboratory.

Zhou Xiaodong said that due to the high cost of planting and high technical content, it still needs further improvement. However, in 3-5 years, the real realization of large-scale production and transformation in the Northeast can be realized.

September in Shenyang was a warm and happy day. It is Zhou Xiaodong's busy rice growing season in Shenyang, Liaoning Province. As agricultural experts such as the Ministry of Agriculture and the Heilongjiang Farming Reclamation Bureau, Zhou Xiaodong took a peasant image and headed into the fields to carefully check the output of rice this year and looked at a golden landscape. Zhou Xiaodong said to himself: “The black land of the Northeast is Whitening, if long-term use of agricultural fertilizer does not change the way of planting, there will be problems with food security."

According to Zhou Xiaodong, China's agriculture must take a new path of scientific research, that is, to protect land resources, but also to securely increase grain production. If the northeastern region achieves dual-season rice planting, it will change the traditional mode of single planting for thousands of years, with both good harvest and high yield.

Zhou Xiaodong told reporters that this type of short-term, early-maturing rice resource with a growth period of only 80 days was developed through more than ten years of scientific and technological breakthroughs. It was derived from wild domestication and mutagenesis techniques, and the use of space breeding methods eventually led to successful selection and breeding. Its greatest advantage is that shortening the growth cycle reduces planting costs. The output per acre can reach more than 1,000 pounds and the second phase can reach 900 pounds. In recent years, in the Liaozhong County of Shenyang City, two years of rice have been planted in one year, and records of planting in the four seasons have been achieved in Sanya, Hainan.

According to the laws of weather, the annual frost-free period in Shenyang is between 160-165 days. The 80-day super-early-ripening rice of this growth period is fully qualified for the frost-free period.

In Zhou Xiaodong's laboratory, the reporter opened more than 10 years ago. He traveled all over China to cultivate experimental records of this super-early rice. From 805 farms in Heilongjiang Province to Sanya City in Hainan Province; from Handan City in Anhui Province to Shenyang City in Liaoning Province. Every year for nearly 10 months, I go back and forth in the four areas of more than 100,000 kilometers.

According to the historical records, no one dared to think and no one dared to do it from ancient times to the present. However, Zhou Xiaodong dared to be a Chinese dream. He told reporters that with the resources and technology he has mastered, the history of planting rice in the past has been rewritten. At present, the rice base in Liaozhong County has been planted in two seasons, with both good harvest and high yield.

"In accordance with the scientific advancement, it is being strongly promoted. Over the past 10 years, this kind of super-early rice has completed various steps in the laboratory, and various indicators have shown that it can adapt to the conditions for planting rice in two seasons in the northeast." Zhou Xiaodong said that at present, this The planting costs are a bit high, and the technical content is high, which does not meet the requirements for large-scale production conversion. However, it can be fully realized and promoted in 3-5 years. By then, it will open a new chapter in rice cultivation in Northeast China.
