Agro innovation to ensure food security

According to statistics released by the Chinese Academy of Sciences, China has more than 40 million mu of medium- and low-yield fields, and 10 million mu of saline soils in four provincial-level divisions, including Hebei, Shandong, Liaoning, and Tianjin in the Bohai Bay rim area.

If technology can overcome problems such as barren soil and the lack of freshwater resources, the potential of these lands could be huge, said Liu.

Researchers estimate that by 2020, the Bohai Bay rim will have the potential to increase crop production by 5 billion kilograms per year.

Back in 2008, Liu and a group of researchers started research on brackish water irrigation technology in Nanpi county. The wheat output that year reached 300 kilograms per mu, and in 2009 the yield rose to 350 kilograms per mu. Last year, the yield topped 500 kilograms per mu.

"Irrigation is important and the seeds were another crucial factor," Liu said.

The "Xiao Yan 81" mentioned by villager Xu was one type of wheat series cultivated by academician Li Zhensheng, a wheat breeding expert.

"Xiao Yan" is a hybrid of wheat and wheatgrass, which gives the new variety great saline-alkaline tolerance.

"The wheat production back then was only 200 kilograms per mu, but after using Xiao Yan 81, the wheat output this year reached 450 kilograms per mu," said villager Xu.

Liu looks forward to the outcome of the ongoing policy meeting, which opened on Saturday, during which the country's leadership is scheduled to outline a broad reform agenda. He said he hoped the new policy could inject vitality into China's agricultural development.
